Re: [EVDL] Bu's e-wheely bad idea weaving-recklessly the wrongway HT delivery

2015-08-23 Thread Peri Hartman via EV

Another significant factor is what an e-bike replaces.

If it merely 100% replaces a pedal-only bike, then clearly it is 
dirtier.


However if it replaces a pedal-only but also replaces 50% of car trips, 
it is incredibly cleaner.  Even if the car is an EV.

Mark,

That is kind of naive, or not resulting from careful thought -
cleanliness of any electric use depends on the power generating 
source.


I have 6kW of solar at home - pretty clean.  If I charged the light EV 
pack
with a gas generator that would be pretty stinky.  Grid power around 
here
is primarily NG from modern plants, so... you can argue about clean 
there
many ways.  I could probably cobble together a wood gas 
generator/generator

that would stink, but be carbon neutral.   Then there are all the other
options.

Light EVs are, if nothing, cheap for low income folks, they help the
sedentary wealthy get some exercise on short trips - just like the 
Vermont

people noted in recent posts.

Light EVs don't waste as much energy because they generally don't go 
very

fast - anything over 12mph has an air drag penalty and 80mph is very
inefficient in comparison whatever the source or vehicle. Air drag is 
the

predominant energy wasting pathway.

Light EVs make a lot more sense in terms of material efficiency as they
don't have to resort to titanium, and aluminum to be lightweight 
(easily
made from recovered scarp and recycled parts).  If you want to do a 
dust to

dust comparison.

A human is incredibly efficient if you can get sufficient distance and 
trip
time.  A few meals of beans and greens will get you a couple hundred 
miles

if you are a hearty and practiced rider. I suspect that is how the vast
majority of the millions of EV bike owners are doing it.  Someone 
recently
quoted there are 126 million light EVs, bikes scooters, and so on.  You 
can
discount the biological miles as not pertinent, but I think the 
pedal/EV

hybrid is a very worth design.  Far cleaner than other alternatives for
most power sources and use cases.

Seriously? Was it properly tuned? Did you drive it at less than wide-open

I can't help but think this is the perfect being the enemy of the good.

Even the worst full-sized gasoline-powered motorcycle is going to get better 
fuel economy than the best econobox, and the average motorcycle pollutes so 
much less than the average passenger vehicle it's not even funny. If 
motorcycles were the norm, we wouldn't be in the pickle we're in today.

Similarly, full-sized electric motorcycles put both gasoline-powered 
motorcycles and full-sized electric vehicles to shame -- and two-stroke 
gas-powered assisted bicycles are even more energy-efficient than full-sized 
electric motorcycles.

And a bicycle with an electric assist? Your stereotypical teenaged girl is 
going to use more electricity drying her hair in the morning than an 
electric-assist bicycle is going to use.

So, is an electric-assist bicycle somehow dirtier than a bicycle without 
electric assist? Does that even deserve to be dignified with a response?

Anything that's not a full-sized gas-powered single-occupant daily commuter car 
is a win for the planet. Full-sized electric vehicles are a fantastic 
replacement...but all the other options should be encouraged as well.

And you will not find iany/i powered vehicle friendlier to the environment 
than an electric-human hybrid.

  This was a wheely bad idea.
 
  A deliveryman on an electric bicycle was arrested after he zipped into the
  Holland Tunnel against traffic and veered around oncoming cars as he made
  his way across the Hudson River span, officials said Friday.
 
  Yongshun Bu, 44, and his motorized bike entered the westbound lane at the
  Manhattan end of the tunnel at 7 p.m. Thursday and was seen recklessly
  riding around traffic, ignoring signs and verbal instructions to pull over,
  according to Port Authority spokesman Joe Pentangelo.
 
  Bu, who was delivering Chinese food according to law enforcement sources,
  was ultimately grabbed about 20 yards into the tunnel and charged with
  criminal trespass.
 
  His wrong-way trip through the tunnel caused a short traffic disruption,

  BEYOND BERGEN: A lower Manhattan deliveryman rode an electric bicycle
  through the Holland Tunnel last night, skirting traffic and ignoring orders
  to stop, before officers grabbed him on the New Jersey tube.
 
  Yongshun Bu, 44, was delivering food when he “recklessly” drove through the
  tunnel around 7 p.m., the authority’s Joseph Pentangelo told CLIFFVIEW
  PILOT.
 
  Port Authority tunnel and bridge agents combined with PAPD officers to take

That particular part of your statement is incorrect.
I used to ride a 1000cc motorcycle that got 30mpg.

Seriously? Was it properly tuned? Did you drive it at less than wide-open

hooked up to it?

I used to ride Kawasaki H-2s.  750 cc, 300-350 pounds as I recall. I 
VERY rarely got more than 30mpg.  It was quite hard to ride them 
slowly.  I did get close to 50 mpg when I could hold it to 50-55 mph.  
As I recall,  a 3.5 gallon tank had to be filled every 100 miles or so.

StoreDot Announces EV at Microsoft ThinkNext 2015
Tamar Depaz May 5, 2015
]

A promise by Israeli nanotech firm StoreDot that within a year it will be
able to recharge an electric vehicle in five minutes has gained some true
believers.

Samsung Ventures and Norma Investments Limited (the investment firm that
represents business tycoon Roman Abramovich), along with other investors,
are providing StoreDot with $18 million for the development of its electric
vehicle (EV) charging technology.

Come next May, StoreDot CEO Doron Myersdorf promised at the recent Microsoft
ThinkNext event in Tel Aviv, “we will present a technology to recharge an
electric car in five minutes. Using an array of 7,000 cells, we’ll take a
car that has a zero charge and recharge its batteries to 100% capacity.
Then, while next year’s ThinkNext is going on, we’ll send it on a trip to
Beersheba and have it come back at the end of the event here to Tel Aviv,”
Myersdorf said in May of this year, to the cheers of an enthusiastic crowd.

The new round of funding, the company said, is centered on the development
and commercialization of its new EV business unit.

StoreDot became famous for its 30-second cellphone recharging technology,
which the company says will be on the market in the middle of 2016.
Altogether, StoreDot has garnered $66 million in funding in its four years
of existence.

In addition to helping develop the EV technology, the new investment will
help StoreDot build the prototype vehicle it plans to send to Beersheba and
back next year, and establish new labs to commercialize the technology.

[StoreDot’s] two development tracks – cellphones and electric vehicles –
have a lot in common. The technology for fast-charging in both devices is
based on the same concept, at different scales. StoreDot’s
nanotechnology-based system turns peptides into energy storage nanotubes,
which can store and emit a large amount of energy at one time, using what
the company calls Nanodots. With a few such dots, a cellphone can be fully
powered in less than a minute. With enough dots – 7,000 – the system can
provide the power needed to get an electric car rolling.

Batteries – both because of their size and the time needed to recharge –
have been major issues for electric car manufacturers, and experts say that
the industry is not going to take off unless batteries can be made smaller
and can charge faster.

StoreDot says it has the solution to both. Its new EV FlashBattery, the
company says, “charges fully in 5 minutes, providing 300 miles (480 km) of
driving distance. This fast charging technology shortens the amount of time
drivers will have to wait in line to charge their cars, while also reducing
the number of charging posts in each station, and considerably cutting the
overall cost of owning an electric car.” Because it charges so quickly, a
battery using StoreDot technology can be smaller, making vehicles lighter
and batteries cheaper to make, as well.

Not only will the system save time, said StoreDot, but “allowing for less
frequent battery replacement due to its increased number of cycles, EV Flash
Battery results in a 50% cost reduction per mile over the electric vehicle’s
lifetime, compared to existing battery technologies.”

Currently, the electric vehicle with the longest range is the $80,000 Tesla
Model S 85 kWh, which can go 265 miles. Only one other – Toyota’s RAV4 EV –
can go more than 100 miles (103, to be exact) on a single charge.

It’s a bold claim, but believable enough to gain the interest of top-flight
investors, who see StoreDot as the company to supply the fast-recharging
technology that is going to turn electric vehicles into the preferred option
for car buyers.

“This new EV division is a natural extension of our proprietary FlashBattery
technology originally developed for the smartphone domain. This funding
brings StoreDot closer to fulfill its vision of a care-free fast-charging
future,” said Myersdorf. “Together with our strategic partners, StoreDot
will accelerate the process of delivering our FlashBattery technology to the
EV market.”

New electric storage material could put more zip in your Tesla

Researchers have developed a new electric storage material that’s among the
best now available—an advance that could allow automakers to build faster
charging electric cars
]

BOSTON—The next electric car you buy might have a little extra zip. That’s
because researchers have developed a new electric storage material that’s
among the best at holding large amounts of charge as well as charging and
discharging in just seconds, they report this week. Moreover, because the
starting materials for making it are commercially available and relatively
cheap, it may prove more useful than higher performance—yet more
exotic—materials currently under development. That could eventually allow
automakers to build faster charging electric cars with a longer driving
range than any on the road today.

The new material, called a covalent organic framework (COF), is a highly
porous crystal. It’s used to store electricity in the heart of devices
called supercapacitors, which are widely used in everything from cars to
computers. In their simplest form, supercapacitors consist simply of two
metal electrodes separated by a conducting liquid, or electrolyte. To charge
the device, you apply a voltage between the two electrodes. That causes
oppositely charged ions to snuggle up to the surface of the electrodes,
where they remain even after the voltage is turned off. When the
supercapacitor is discharging, electrons flow from the negatively charged
electrode to the positive one, doing work along the way.

Because the transfer of electric charges happens so fast, supercapacitors
can be charged and discharged in seconds, compared with the hours it takes
for batteries. That’s made them ideal for applications such as regenerative
braking systems in electric cars, which use the energy in braking to
generate an electric current that is stored instantly.

The trouble is that the storage capacity of supercapacitors is limited by
the surface area of the electrodes, which is far less than the volume-based
storage of a battery. Not surprisingly, companies have sought to increase
the surface area of their electrodes by making them out of porous,
conductive materials like activated carbons, which now dominate the market.
Of course, they are always looking to do better.

One solution is materials with very high surface areas, such as carbon
nanotubes and graphene. Both of these are made from single layers of carbon
atoms, and have been used to make the highest capacity supercapacitors to
date. But the materials themselves remain expensive and relatively difficult
to produce in the volumes that would be needed for large-scale applications.
Another electrode-building material is redox-active molecules, which readily
absorb electrons and later give them back up. But redox-active materials
have their own challenges. Some fall apart after electrons cycle on and off
a few times, and others aren’t porous enough for making good
supercapacitors.

William Dichtel, a chemist at Cornell University, showed 2 years ago that
COFs can do better. Dichtel and colleagues reported making the first-ever
redox-active COF, assembled from organic building blocks
2,6-diaminoanthraquinone (DAAQ) and 1,3,5-triformylphluroglucinol (TFP).
Under the right conditions, Dichtel’s team found that DAAQ and TFP
spontaneously assemble themselves into large hexagonal rings with single
holes in the center. What’s more, the hexagons link together like sheets of
tiles on a bathroom floor. Additional sheets form on top of the first with
all the holes lining up. Ultimately, the material becomes a regular crystal
of tiled and stacked hexagons shot through with tiny pores, giving them a
surface area similar to activated carbons.

But because redox-active COFs have the ability to absorb electrons as well,
they have the potential to make better supercapacitor electrodes. Earlier
this year, the researchers reported that when they grew their material as
thin sheets atop a gold electrode, the COF had a capacity of about 160
farads per gram (F/g) of material. That wasn’t yet as good as the best
commercial supercapacitors. The problem was the COFs themselves weren’t very
conductive, even though they could charge and discharge quickly and hold an
impressive 12 electrons per hexagonal tile. The lack of conductivity meant
that the electrons in the upper portion of any COF more than 200 nanometers
thick wouldn’t be able to make it to the electrode. “There was no way to get
the charges out of the thicker films,” Dichtel says.

Until now. At the meeting of the American Chemical Society here this week,
Dichtel reported that he and his team got over their size hurdle

MONTPELIER – For a few minutes, David Cohen wants Vermonters to set aside
the possibility that they might ever run errands, in the winter, on a
traditional bicycle.

With that image banished, Cohen conjures up another: Grocery runs, shopping
trips, hauling kids or just exploring roadways — on cycles that are sturdy,
emphatically utilitarian and boosted by small electric motors.

Here in the hilly Green Mountain State, Cohen asserts, cargo bikes with
power-assisted pedaling are a no-brainer.

Furthermore, they're poised to transform our energy-wasting, car-centric
transportation habits, he says.

Will the revolution be fun? Only one way to find out.

Are we cheating yet?
Last year, Cohen, 55, a Brattleboro-based therapist, founded VBike, a
nonprofit devoted to advancing the adoption of bicycles that would play a
more central role in our daily lives.

Not that he has anything against a recreational ride.

But Cohen's threshold for a really useful bike in these parts is something
that can climb hills, with a load, without exhausting the rider.

Hard-core (mostly younger) bicyclists have suggested to him that
electric-assist constitutes a form of cheating.

It's an argument he's heard before — and an argument he favored in his
earlier days of bicycling.

Almost exactly 20 years ago, in the San Francisco Bay area, Cohen launched
Pedal Express, a bicyclist-powered haulage company. One of the rigs in his
fleet could manage a 1,000-pound payload.

Back then, people used to say, 'Hey why don't you put a motor on that
thing?' — and I'd be like, 'No: We're really trying to experiment with what
the human body is capable of doing.'

When he and his wife moved to Vermont in 2007, his appreciation for compact
communities firmed up. So did his respect for hilly terrain.

It became obvious, Cohen said. Bike transportation culture is not going
to happen, it's not going to take off in Vermont — unless we have bikes that
are relevant to our needs.

Rather than endorse ever more-strenuous workouts and ever-lighter cycles,
Cohen strives to build a critical mass of bicyclists

Accidental nanoparticles could let lithium ion batteries live another day
By Graham Templeton  August 18, 2015

battery nanoparticle
]

A new study from MIT could keep lithium ion battery technology on the track
for another few laps, allowing further improvements while we wait for a
fundamentally better solution to arrive. The breakthrough comes from an
accidentally created synthetic metal nanoparticle that could solve some of
the oldest problems for batteries. Their testing shows that the
nanoparticles could allow up to four times the charge retention after a long
lifetime of use, meaning devices could last longer and create far less
unnecessary pollution.

Not long ago, scientists discovered that the main reason lithium ion
batteries lose their capacity over many charge-discharge cycles has to do
with expansion and contraction of the graphite electrodes at either end.
When electron-laden lithium ion diffuse across this gap and offload their
electrons at the other side, they stick to the electrode there, and can snap
off as the whole thing expands and contracts. This removes some lithium ions
from the system, thus reducing the total available charge in the battery.

This expansion problem is one of the reasons graphite has been used for so
long, since it undergoes relatively little change throughout the battery’s
use. In particular, aluminum has been a frequent candidate to replace
graphite, but tends to get discarded because it expands and contracts too
much, and because it builds up an unhelpful coating when exposed to air.
Researchers from MIT were attempting to address this problem with different
treatments for aluminum nanoparticles — and that work led them to bathe
nanoparticles in a mixture of sulfuric acid and titanium oxysulfate, with
the intention of replacing the aluminum oxide coating that results from
reaction with the air with a more practical coating of titanium oxide.

The issue arose when the team accidentally left a sample of aluminum in the
bath for several hours longer than their technique required. This resulted
in an unforeseen egg-like nanoparticle design, in which a “yolk” of aluminum
is covered in a “shell” of titanium dioxide. What’s important is that there
is some space between the yolk and the shell (where the metaphorical “white”
would go), which allows the aluminum to expand and contract as it is wont to
do without affecting the titanium shell around it. This means that the
aluminum can react to the regular charge-discharge cycle without trapping
and removing any of the lithium ions themselves.

The delay in removing the aluminum from the chemical bath did not result in
the shell around the aluminum core, which would have been there anyway, but
rather the shrinking of that core to a “yolk” with the all-important
internal space. Though the team had not meant to create that unintentional
chemical product, the researchers did have the insight needed to put the
particles through their experimental paces, rather than simply throwing them
out. Whether they did this because they thought it might produce something
useful, or simply wanted to be diligent even with their failures, is
unclear.

What is clear is that lithium ion batteries need a breakthrough like this to
keep moving further into people’s lives. Charge-discharge capacity has a lot
to do with the lifetime costs of things like electric cars — if you could
regularly drive an all-electric car for several years without much real risk
of having to replace the battery pack, electric cars would become much more
affordable over their full lifespans.

Fully alternative technologies, from carbon-based batteries to
super-capacitors to mini-nuclear charging, have been predicted to kill
lithium ion for many years running, at this point — I’ve made the prediction
myself, more than once. What I think is often underestimated is the sheer
install base of the technology, partially with customers, but more
importantly with manufacturers. Though Elon Musk insists it will be at least
somewhat modular to accept newer battery technologies, the Tesla Gigafactory
is built to create lithium ion batteries; there is a significant economic
incentive to keep improving lithium ion batteries, and to put off a
large-scale switch as long as possible.

How long that stalling process can possibly continue will depend on how
rapidly our power demands increase over time, and how willing society is to
shell out to fulfill them.

Motorcycles are particularly bad if you look at person miles per gallon,
but so many cars are driven solo.  None of that is an issue for light EVs.I
had a variety of 750's and 850's (4 cycle twins) in the 80's and got no
more than 45mpg.

Seriously? Was it properly tuned? Did you drive it at less than wide-open 
throttle and / or triple-digit speeds? Did you have a thousand-pound sidecar 
hooked up to it?

Was working correctly and well tuned.  It was just old.  Hmm, just checked my 
old notes, it was getting 35mpg.
Driving at 65mph on the freeway mostly.
Many larger bikes, get pretty crappy mileage, and many econobox cars get better 
mileage than the big bikes.

2015-08-23 Thread Cor van de Water via EV
Let's do the math:
If I go to work, mostly I drive my EV truck which on the freeway uses
at least 160-200A at 120V to maintain an easy 55-60MPH so it uses about
200x120 = 24kWh for 60 miles or about 400Wh/mi

Once a week on avg I ride my e-bike to work. Now, I like to work out
to I typically ride it without motor, but let's suppose that I did ride
the same 11 miles one-way on electric power, just as when riding my truck
(not on the freeway, of course, but there is a parallel route that is
about the same distance as taking the freeway)
Then the consumption is about 300W for a speed of 20MPH so about 15Wh/mi

No matter where the power comes from, the bike uses about 1/30 the energy
that my truck uses for the same distance, so how can this be dirtier?

Cor van de Water via EV wrote:

My pack of 20 Golfcart batteries is now almost 4 years old and
it has brought my truck over 14k miles so far, but tonight when
I inspected a couple of the batteries I noticed something strange -
while some cells had minimal water loss (level about 1/2 under the
top of the cell) there were several other cells that barely had their
plates covered, the level had gone down more than a full inch in those!
How can this difference be explained?


4-5 years is about right for Sam's Club (Eveready a.k.a. Interstate) 
golf cart batteries. That's what I've been getting, too. Trojans and US 
Battery brands are a little better.


As others have noted, water usage increases as a flooded lead-acid 
battery ages. This happens for several reasons; some due to the battery, 
and some due to the charger.


Flooded batteries use a lead-antimony alloy for the plates. The antimony 
hardens the plates (makes them stronger), which extends life. But it 
also increases water usage, the self-discharge rate, and lowers the 
fully-charged voltage.


As the battery ages, the antimony migrates to the surface of the plates. 
This worsens all these effects. The battery gasses more, uses more 
water, and its fully charged voltage will be less. (It doesn't otherwise 
affect the amphour capacity, though. Loss of capacity comes from other 
effects.)


Most chargers do not compensate for new/old batteries. They blindly 
charge all batteries as if they are new. This means that old batteries 
get charged to too high a voltage. That significantly worsens gassing 
and water usage. The resulting chronic overcharging also shortens life. 
(This is why the batteries in an old batteries tend to suddenly all 
die together).


Big industrial EV chargers use the dv/dt or di/dt algorithms to 
compensate for battery age, and thus extend their life. Rather than 
charge to a specific ending voltage (or current), they charge until the 
*rate of change* in voltage or current goes below some limit. If your 
charger has this option, use it.


If not, your best bet is to reduce your charger's end-of-charge voltage 
(for example, from 2.5v/cell to 2.45v/cell). Also increase your final 
charging current (from 4 amps to 8 amps). In other words, rather than 
shutting off at 7.5v at 4 amps, change it to shut off at 7.35v at 8 amps.


Old batteries also need more frequent equalization. While you might only 
need to do this every 2 months when new, it could need to be done ever 2 
weeks when old. Equalization is a long slow low-current charge to an 
unlimited voltage. Basically, you charge at something like 2-4 amps 
until the voltage stops rising.


If you take care of them in their declining years, the batteries can 
easily provide double the life and number of miles before the pack needs 
to be replaced. :-)

Re: [EVDL] Difference in water use per cell for GC batteries

2015-08-23 Thread Cor van de Water via EV
Thanks Lee,
I am charging sparingly anyway, because I need to keep my household
electric consumption close to 300 kWh per month or pay a hefty higher rate
for the overage, I managed to get the home itself near 100 kWh/mo by switching
to LED lights and using a gas dryer, heater and cooktop and the 3 adults in
the household use a laptop each, so the times that I charge (typically 4 
weekdays
as I like to commute by bike once a week) and at least once a weekend, I can get
about 10kWh per charge and stay around the 200 kWh/mo budget for charging; 
luckily
I can charge at work as well, so typically I leave work with an (almost) full 
pack
after 6-8 hours of level 1 charging. (I tend to start my work from home, then go
to the office after traffic has cleared).
Since I also charge level 1 at home, my charging current is never more than 12A,
ramping down to below 10A when charging is under way or when the grid is weak at
the outlet, only if I plug in at a 240V J1772 can I get 20A of charge current 
into
the pack (120V nomonal, rising to ~147V under full charge, with current falling 
to
about 4-5A at that voltage from the resonant transformer. The only thing I can 
select
on my Bycan charger is whether I want the shutoff after 2 hours or 8 hours after
detecting the 147V max charge voltage. (The latter is the equalizing mode)
The charger is not often allowed to complete this anyway, on average 1 or 2 
times a month.

I am a little concerned if I may have reversed a few cells at the moments that 
I needed
to go a little further than the pack wanted, due to unexpected hills or when 
driving 
more freeway (fast) than anticipated, causing the pack to sag (under load) 
below 90V
which I then tend to counter by reducing power and trying to keep voltage above 
90V
under load, nursing the car along until I can plug in an recharge immediately...
Anyway, time will tell if these cells are weak and deteriorating or simply 
getting older.

Mark,
I think you are confused between a motorized bicycle which is the language
that the traffic law uses for a bicycle with a small ICE, typically a single
piston two-stroke engine (polluting, noisy and resembling a moped, but slower)

and the electric bicycle aka eBike which has no emissions (other than the
long tailpipe if it is charged from grid power and not from 100% renewable.

Almost all assisted bicycles that I see anywhere are e-Bikes, due to the
lack of hassle (no maintenance, fill-up, fouling, heat, noise, smell and so on.
Just charge and go.

Two-stroke engines are hi emission.

 motorcycles were the norm, we wouldn't be in the pickle we're in today.
 
 Similarly, full-sized electric motorcycles put both gasoline-powered

 electric motorcycles.
 
 And a bicycle with an electric assist? Your stereotypical teenaged girl is 
 going to use more electricity drying her hair in the morning than an 
 electric-assist bicycle is going to use.
 
 So, is an electric-assist bicycle somehow dirtier than a bicycle without 
 electric assist? Does that even deserve to be dignified with a response?
 
 Anything that's not a full-sized gas-powered single-occupant daily commuter 
 car is a win for the planet. Full-sized electric vehicles are a fantastic 
 replacement...but all the other options should be encouraged as well.
 
 And you will not find iany/i powered vehicle friendlier to the 
 environment than an electric-human hybrid.
