Re: [EVDL] Towing with a Bolt

[Cor van de Water via EV]

It usually comes down to three things-Warranty, design load and pilot 
expectations.If the manufacturer does not want to take responsibility for the 
unheard things that some people manage to do with a hitch, they will simply say 
that a hitch voids warranty.The design load of the frame will limit how much 
extra load the car can take before things start to deform and since an EV is 
designed to be light, there may not be too much margin. Note that it is not 
about the static load on the hitch ball, which is supposed to be pretty low for 
a well loaded trailer, but the dynamic loads, especially for a non braking 
trailer can be pretty high and tear on the frame.Then there is the issue of 
expectation. Drivers might expect to be driving their usual 70 to 80 mph and 
either put themselves in danger by exceeding the capabilities of the car or be 
dismayed by the limitations, not leading to a positive experience and if the 
towing feature is not a selling item then it won't be valued as such.

Towing with a Bolt 
Hi All, 
   My bro asked me a question I never worried about with Civicwithacord, nor my 
LEAF: Why is it so bad to toe with an EV?/Warranty voiding?

My first answer was of course, range drop with rolling resistance and added 
weight requiring more amps. 
My second answer was guessing that more amps mean more heat as well as worse 
voltage sag on the traction pack. But am I missing anything else?

Appreciatively, 

Bob Bath, from his iPod, so any misspellings are from autocorrect or fat 
fingers on a small device, not cluelessness..

Towing with a Bolt
]

The question posted asks about towing with an EV in general. I feel others
have answered that.

But the subject/topic of the post specifically asks towing with a Bolt EV.

I would first see what others have done, by checking with what the Bolt
drivers have posted
https://www.google.com/search?q=chevy+bolt+towing

And then, because the Bolt's underpinnings are based on the Chevy Sonic ice,
you could also look to what the Sonic drivers have posted
https://www.google.com/search?q=chevy+sonic+towing

Which btw also gives:

https://www.etrailer.com/vm/Chevrolet/Sonic/hitch
Chevrolet Sonic Trailer Hitch
For your 2015 Chevy Sonic the Draw Tite Hitch part # 24878 has been
confirmed as a fit and will work well for light towing as long as you stay
under the hitch's towing capacity of 200 lbs tongue weight and 2,000 lbs
total trailer weight and the towing capacities for the vehicle listed in the
owners manual.


That last bit is what you should have already read (the Bolt manual - rtfm)
to know the Bolt EV's design limitations.

[EVDL] Hot wire

[Seth Rothenberg via EV]

We had an over temperature event here recently.  In Jan 2016, I bought a
2013 Nissan Leaf.  Around May, I bought an OpenEVSE.   I had saved six
L6-30 power cords from servers I retired.  I removed the proprietary
connectors and put on L6-30Rs to make extension cables.
I used the combination for 18 months - usually 3 extensions and a 10-30
adaptor I made.  The EVSE is limited to 24Amps.

Last week, one of the junctions got hot enough to melt the plastic of the
plug.
Fortunately I was home to detect it.

I took it out of service until I could replace the damaged L6-30R and then
I monitored the connections.  One L6-30 junction and the 10-30 junction
both show 100 Farenheit while in use.  Is that normal?   Maybe I need to
exchange the surplus L630Rs with new ones.

I plan to work on getting an L6-30R outlet near the parking space.  But it
would be nice to have confidence in these cables.

Thanks

Re: [EVDL] Towing with a Bolt

[David Chapman via EV]

I would worry about the trailer exceeding the limit of the brakes more than 
anything. If you are talking about a little 4x3 Harbor freight utility trailer 
for flat ground around town use thats one thing but anything bigger might be 
unsafe especially in less than optimal conditions

There's no issue with volts or amps; the primary thing that will happen as

I hate to rain on folks' parades (even though it's raining today where I 
am), but this thread has almost nothing to do with EVs now.  I tried to 
bring it back on topic, but to no avail.  Maybe you could take it to private

I think this is less true of recent heat pumps.

I'd like to hear from someone who owns an EV with a heat pump -- how 
warm

does the air from the vents feel in the winter?

I think that many or most older heat pumps did have this annoyance.  
It's

not an EV, but I knew someone who had a late-1990s GSHP (Waterfurnace
brand) at home.  The heating air from the vents always felt cool to me,
meaning that it was below body temperature. Ninety deg F would be quite
believeable.

That's definitely not the case with my Mitsubishi mini-split from 2013.
Although I haven't measured its outlet temperature in heating mode, 
most
of the heating seasons it feels quite warm, almost hot.  So it has to 
be
well above body temperature.  As the outdoor temperature falls, its 
outlet

temperature declines too.  However, it stays noticeably above body
temperature down to an outdoor temperature of around -15 deg C.

Thus I see no reason that an EV heat pump would have to produce air 
that
feels cool under most conditions.  For the times that it did, I'd 
expect

it to have auxiliary resistive heat.

Re: [EVDL] Heat pump vs resistive Heater (never buy another AC unit)

[Peri Hartman via EV]

In your case, Cor, I think insulation is the key. If heat loss is 
minimal, the gradients inside will be minimal. Insulation would also 
make a big difference in an EV. But not so easy, perhaps.

Jim,You perfectly describing the situation where the design of the 
heating system is inadequate for the building, which typically happens 
when it was not designed but someone just installed something and hoped 
for the best.My mom had her house converted to floor heating, which 
included insulation under the floor. I do not know a house more 
comfortable than hers, while she has significantly reduced her heating 
costs. The heat capacity and insulation is such that the house loses 
only a few degrees overnight when her heater is off. Actually the 
thermostat is just reduced a few degs but the heater does not come on 
all night even with freezing temps outside. Our house loses several 
tens of deg in a few hours...

Cor van de Water said (in part):

I have always been amazed by how most of USA has forced air blowing
around through their house, which I find
rather uncomfortable. I am from Europe, where you have radiators under
windows that are warmed with
warm water and air in the room naturally circulates at a very low 
speed

(natural convection) throughout the room.



You're entitled to your opinion, but I HATED radiators which were the 
norm in schools when I was a kid.  You always ended up with the kids on 
one side of the room frying while the kids on the other side of the 
room wearing heavy jackets to keep warm.  Same thing with the floor 
furnace that was in my grandparent's house.  In cold weather we'd all 
huddle within 10 feet of the furnace while the rest of the house was 
frigid.

Tesla fires back at claims that its cars suffer from major quality issues
November 28, 2017  Matthew DeBord

A Tesla Model S.  / Tesla
]

  -  Reuters reported that Tesla's Model S and Model X vehicles suffer from
frequent flaws.
  -  But Tesla has never been outstanding at the nuts-and-bolts aspects of
carmaking.
  -  On track to deliver 100,000 vehicles in 2017, Tesla appears to enjoy
endless owner patience.


On Wednesday, Reuters reported that more than 90% of new Tesla Model S and
Model X vehicles have some sort of problem or flaw that needs to be fixed
before the vehicles can leave the factory.

Reuters cited unnamed workers and reviews of unconfirmed "figures from
Tesla’s internal tracking system as recently as October." The news agency
also reported that "people told Reuters of seeing problems as far back as
2012."

That was the year the Model S sedan went into production as the company's
first all-Tesla vehicle (the original Tesla Roadster was built in a chassis
supplied by Lotus).

Tesla pushed back against the report.

“Our goal is to produce perfect cars for every customer," a Tesla
spokesperson said in a statement emailed to Business Insider. "Therefore, we
review every vehicle for even the smallest refinement."

The statement went on to point out that Tesla strives to go over its
vehicles with a fine-toothed comb, post-production.

"The number of labor hours needed to complete a vehicle has decreased 33%
since early 2016," Tesla said.

"Of the 250,000 Tesla vehicles ever produced, more than half were built in
the past 18 months. Whereas before, it took three shifts with considerable
overtime to produce our target annual production of 100,000 Model S and X
vehicles, now it can be done with only two shifts and minimal overtime."

Tesla says customers are very happy ...


So what are we to make of the Reuters report?

Not much, and I say this as someone who has made a hobby of studying nearly
every Tesla vehicle I spot in the wild for quality control issues, chiefly
large gaps between body panels. For the record, I've tested just about every
trim level of every vehicle Tesla makes and for the most part, the quality
has been quite good. I'm not sure how the cars would fare over the long
haul, but Tesla owners seem to be a very happy bunch. 


According to Tesla, the company "has the highest customer satisfaction
levels and the highest percentage of customers who say that their next car
will be a Tesla in the entire global auto industry.”

It's also worth noting that demand for the Model S and Model X has been
solid enough to bring 2017's projected deliveries tally to a record 100,000
vehicles.
Production problems are nothing new

Quality does matter on luxury vehicles that sell for $100,000 on average.
But Tesla has always been iffy on the nuts and bolts of the business. That
hasn't changed with the new Model 3, either, as Tesla is struggling to
achieve its ambitious production targets with the car, a $35,000 mass-market
effort.

People who want to buy a Tesla just don't care. They're invested enough in
the brand — its snazziness and excitement, it transformational nature — to
overlook stuff that would offend the owner of a used Honda Civic. But that's
the crux of the matter: anybody can buy a Civic, but you have to commit to a
vision of a gasoline-free future to buy a Tesla, so you're investing in
something more than bulletproof build quality.

Tesla has also always had production challenges. The Model S had 'em in the
beginning, as did the Model X and the obviously the Model 3 continues this
theme. 
Tesla disputes quality issues 

Tesla does care, however — it knows that the patience of owners can't be
taken for granted. The company disputed the 90% figure cited by Reuters,
maintaining that vehicles can't leave the factory unless they have no
problems whatsoever. So anything that doesn't pass muster is checked out and
fixed. 

The company also contradicted Reuters' report that flawed vehicles are moved
to a separate location for further work.

The Reuters story concerned the Model S and Model X, but as far as the Model
3 problems go, they could be easily solved by Tesla outsourcing some
production to an experienced and capable contract manufacturer. But that
would undermine the company's narrative of end-to-end control of the vehicle
experience. An outside manufacturer also might not want to engage in the
extensive examination of vehicles that Tesla says is what leads to smaller
issues being caught before a car leaves the factory.

Arguably, the trade-off wouldn't be worth it, although if the Model 3
doesn't hit its mid-2018 targets, Tesla may have to consider this option.

Tesla is trying to get as many electric vehicles on the road as possible,
and that master plan could set it up for h

Proterra Catalyst E2 e-bus
]

Proterra, an innovator in heavy-duty electric transportation, announced that
the San José City Council has approved the purchase of ten Proterra Catalyst
E2 zero-emissions battery-electric transit buses and related charging
infrastructure for use at the Norman Y. Mineta San José International
Airport (SJC). The Council selected Proterra as SJC's battery-electric bus
provider citing the company's sustainability, performance and operational
cost-savings excellence. This purchase marks Proterra's first airport
electric bus deployment in the San Francisco Bay Area. Scheduled to be
placed in service in late 2018, the buses will be designed and built in
California at Proterra's Los Angeles County manufacturing facility.

 "The addition of this all-electric bus fleet reflects SJC's continued
commitment to delivering a world-class passenger experience and advancing
our community's collective sustainability goals," said San José Mayor Sam
Liccardo. "These electric buses can help us significantly reduce costs and
greenhouse gas emissions, and represent a step towards our aspiration that
an electric engine power every shuttle and bus on San Jose's streets." 

With 12 million passengers annually, SJC currently provides on-site shuttle
buses to transport passengers and luggage among the airport's short- and
long-term parking lots, consolidated rental car garage and terminals, with a
fleet of compressed natural gas (CNG) buses. Funded in part by a $3.8
million zero-emissions vehicle grant from the Federal Aviation
Administration, the new Proterra battery-electric buses will replace these
older CNG buses, resulting in the elimination 3.1 million pounds of
greenhouse gas tailpipe emissions over the lifetime of these vehicles.

Since the Proterra electric buses have no combustion engine, riders will
enjoy a quieter, smoother, exhaust-free ride. In addition to traveler
benefits, the operational cost of electricity, at $.19/mile, is
substantially lower than diesel, at $.84/mile. Combining this with greatly
improved vehicle efficiency, at 21 MPG equivalent, vs. 5 MPG for their
current CNG buses and reduced vehicle maintenance costs will result in an
estimated savings of about $4 million during the 12-year lifetime of these
ten new Proterra buses.

 "This purchase builds upon initiatives SJC has put in place to address the
concerns and interests of the community and the environment," said Director
of Aviation John Aitken. These include recycling and composting programs
supporting a zero waste commitment by 2022, a 1MW, 3.4-acre solar array
powering the airport's rental car garage and a shift to airside electric
service vehicles reducing emissions from operations. Complementing these
efforts, SJC's Terminal B received a Silver LEED certification—one of the
first airports in the U.S. to receive the honor—for its innovative use of
building materials to reduce energy use.

 "As the community synonymous with innovation, Silicon Valley is the
breeding ground for technologies that continue to change the way we live,
work and play. SJC's pioneering vision to transition their fossil fuel fleet
to a zero-emission fleet underscores the area's spirit of innovation and
matches Proterra's goal of providing clean, quiet transportation to all,"
said Ryan Popple, CEO, Proterra. Last Mile Electric Vehicles 2018-2028 

The Federal Aviation Administration's Zero Emissions Airport Vehicle and
Infrastructure Pilot Program was created in 2012 to improve airport air
quality and facilitates use of zero emissions technologies at airports.
Grants are awarded for up to 50 percent of the cost of zero emissions
vehicles and associated infrastructure. 

Mineta San José International Airport (SJC) is Silicon Valley's airport, a
self‐supporting enterprise owned and operated by the City of San José. The
airport serves 12 million passengers annually, with 200+ peak daily
departures on 16 international and domestic carriers to 53 nonstop
destinations. SJC was America's fastest‐growing major airport in 2016, based
on percentage increase in passenger seat capacity.

ABB to help charge Gothenburg’s electric buses
27 Nov 2017

https://smartcitiesworld.net/AcuCustom/Sitename/DAM/011/news-transport-nov17-oppgoth.png
The order comes after a successful two-year trial under the ElectriCity
venture
]

Project is a partnership with Göteborg Energi, Volvo Buses, public transport
agency Västtrafik and power and automation group ABB

Swedish energy company Göteborg Energi has placed an order for two fast
chargers for articulated high-capacity electric buses in Gothenburg.

Due for delivery in spring 2018, the 450kW Opportunity Charging (OppCharge)
from ABB will be installed at Sahlgrenska University Hospital and Eriksberg
Square, on line 16 of the city’s bus network, on which two prototype
electric articulated high capacity buses from Volvo will operate.

OppCharge is an open interface for the automated charging of both single and
double deck electric buses, which can be utilised by any manufacturer, using
a pantograph on the infrastructure to connect the bus to the charging point.

The order comes after a successful two-year trial under the ElectriCity
venture during which 10 all-electric or partially electrified buses have run
on the Swedish city’s bus route 55.

“The fact that the chargers operate so quickly is vital for keeping traffic
moving and for increasing the capacity of the network,” added Fredrik
Persson, project manager at Göteborg Energi. “The efficiency of ABB’s new
charging stations in combination with their high performance is the key to
the concept.”

When the Volvo Ocean Race is staged in Gothenburg in June 2018, two
electrically powered articulated buses will showcase the latest
developments. These two prototype buses will then run on route 16, which
will be equipped with charging infrastructure and bus stop facilities for
electrified high-capacity traffic.

“We are committed to providing charging solutions for Gothenburg, whether
that is for EV passenger cars or for the city’s public transport network,”
added Lotta Brändström, CEO of Göteborg Energi.

“The transition of the transport sector is one of our biggest challenges and
we understand that this will take the combination of many different
solutions.”

“We are proud to be partnering with Volvo, Västtrafik and Göteborg Energi on
delivering this efficient charging solution for the city of Gothenburg,”
said Frank Muehlon, head of global business for EV charging infrastructure,
ABB.

“This project marks another positive step in an ongoing partnership between
ABB and Volvo, which has seen our companies work side by side since 2014 on
co-developing city-wide electric bus solutions for improved and sustainable
urban mobility.”

Göteborg Energi specialises in electricity, district heating and electricity
networks, gas, cooling, energy services and city fiber. The company is
working towards a sustainable Gothenburg society by, among other things, a
smarter, more sustainable housing programme and the reduction of CO2
emissions in the city.
