I'd been on the road for a week or two, so I was itching to tug on a
throttle cable when I got back to Santa Cruz. Luckily, thanks to the
worldwide brotherhood of motorcycle people, a KTM Superduke fell in my lap
thanks to Liza Miller of the Motorcycles & Misfits podcast community and I
was able to get out on the road with some local riders.

In our gaggle of bikes, one stood out, not because it was electric, but
because of the drama playing out on its tank. "Electric Terry" Hershner now
rides with Charger, a canine companion whose sled dog genes get her
extremely excited when she's riding in a pack. As a result, despite the fact
that she's clipped on to Terry at all times, she's all but turning
somersaults as we wind our way up through the twisties.

She absolutely loves riding, and absolutely hates being away from Terry's
side, as I'd earlier discovered when I got the job of driving her 50 miles
from Carmel to Scotts Valley as Hershner rode a bike that wasn't set up for
her.

At the end of a fun afternoon on fast bikes, I sat down again with Electric
Terry to finish our chat about the first electric Ironbutt, the Vetter
Challenge, riding with his manic dog Charger and a future in which two-way
EV charging can support the power grid. Check out Part One here if you
haven't already. What follows is an edited transcript of our conversation:

Loz: So everyone's aware that long-range riding is a weak point for electric
motorcycles. How do the numbers work out for an electric Ironbutt attempt?

I did the Ironbutt, a thousand miles (1m609 km) in 24 hours, in 2014. I did
about 150 miles (241 km) per charge, and I'd charge in a little under an
hour using four J-plugs at a time. I had to find locations that had four
next to each other, and I'd use them all.

I met the CEO of Chargepoint up near San Jose, he said "tell you what, you
leave here right now, and come back with a bottle of authentic tequila from
Mexico in less than 24 hours, using all my company's charging stations, and
I'll give you a sum of money."

So we got pictures of us shaking hands, and the deal was on. And I made it –
I didn't buy the tequila, but I made it to Mexico. If I'd gone across the
border to get tequila, I would've lost about five hours in the border
crossings.

I made 1,047 miles (1,685 km) in a little under 23 hours. I was the first
guy to get an Ironbutt on an electric motorcycle. The President of the
Ironbutt association sent me a note saying "we knew this was coming
eventually, but we thought it was still a couple years out.
Congratulations!"

Loz: So tell us about the Vetter Challenge.

The Vetter Challenge is an event where people from all over the world get
together to compete and see who can go the furthest distance on the least
fuel, as measured in dollars and cents.
August 31st 2014: at the Bonneville Salt Flats after becoming the first
electric to win a...

Loz: so it's an aerodynamics challenge.

Yes. Every time there's a fuel crisis, there's suddenly a lot of interest in
aerodynamics. In the late 70s, there was a fuel crisis, so Craig Vetter
started doing these things called the Vetter Challenges. He held them from
1981 to 1985, and every year the gas mileages just started getting better
and better.

It started out at just over 100 miles per gallon (2.35 l/100km), people on
250cc bikes, some on 125s and 100s. They'd put aerodynamics on them, and
they'd have to get from point A to point B in a certain amount of time so
you couldn't sandbag.

I think it was a guy named Charlie Perethian, or Masakazu Matsuzawa, one of
them, using a rifled fairing, got 470 miles per gallon (0.5 l/100km) by
1985. It was a tiny little XL80 motorcycle, big aerodynamic fairing, and
he's tucked in real small.

Anyway, Craig started the Challenge again in 2010 when gas prices went back
up. And now you could use alternative fuels and electric vehicles. And we
did it by cost – add up the cost of the fuel to cover whatever distance, and
the lowest cost is the winner. With electric, because a

Porsche claims all-electric Mission E will maintain high-speeds longer than
Tesla’s Model S
Mar. 1st 2018  Fred Lambert

[image  
https://electrek.files.wordpress.com/2015/12/mission-e-1-e1449248142300.jpg
]

We know that for a while now Porsche has been benchmarking its upcoming
first all-electric vehicle, the Mission E, against Tesla’s Model S.

While the latter’s current version seems to already beat many announced
performance specs of the former, we have always believed that track
performance and long high power outputs could be areas of focus to improve
on for Porsche in this new electric car.

Now the company has confirmed it and took a swipe at Tesla in the process.

As we recently reported, Porsche seems to be working hard to sell its
electric transformation to its motorhead fans and they have been releasing a
series of interviews and press releases in order to push that lately.

In the latest of those interviews, Stefan Weckbach, Head of Battery-Electric
Vehicles at Porsche, was asked about the fact that Tesla can achieve an
acceleration from 0 to 100 km/h (62 mph) in under three seconds.

He responded:

“But only twice – the third attempt will fail. The system is throttled.
Porsche drivers won’t need to worry about anything like that happening. The
Mission E will offer reproducible performance and a top speed which can be
maintained for long periods. And that’s not all. The longitudinal and
lateral dynamics of the Mission E will be typical of a Porsche and represent
a real treat for any driver.”

The “throttled” comment is actually incorrect. While Tesla has limited the
power output of its performance vehicles in the past, owners have still
access to the full power through Tesla’s launch mode.

Furthermore, while it’s true that acceleration is affected by the state of
charge of the battery pack and temperature of the powertrain, among many
other factors, it would be inaccurate to say that Tesla Model S drivers
can’t launch the vehicle more than twice before they can’t achieve a 0-60
mph acceleration in less than 3 seconds.

Drivers have launched the Model S P100D on the race track a dozen times with
similar 0-60 mph times (down to about 2.5 seconds now).

When it comes to maintaining a top speed for long periods, Weckbach is right
that Tesla’s vehicles are not optimized for that and lose a lot of range
when trying to maintain high speeds.

As for the Mission E, Porsche has only confirmed a few specs about the
vehicle, like “over 310 miles of range” (500 km) NEDC, which is likely
closer to around 250 miles of real-world range, and a 0 to 60 mph
acceleration in 3.5 seconds.

Electrek’s Take

I have a few problems with his comment because it either shows that he is
misinformed about the Model S, which he shouldn’t be since his team has been
benchmarking the Mission E against it, or that he is lying to make their
vehicle look better against it.

That’s not a good look either way.

With this said, he does have a point about maintaining a top speed for long
periods. We already suspected that it could be a focus of the German
automaker on the Mission E since there have been complaints from some Tesla
owners who like to drive at high speeds on the Autobahn.

It’s interesting to see them now confirming that they are going in that
direction, but it’s not like he confirmed any specifics and we will have to
see how it translates into actual performance.

I’d also keep in mind that the vehicle is still about a year away from
production and Tesla may have an answer to those problems by that time. We
will have to see.

But competition is certainly heating up and that’s interesting.

MILWAUKEE — Harley-Davidson says it has acquired part of a California
company that’s been making electric dirt bikes for eight years, and that it
will collaborate with the company, Alta Motors, on Harley’s future electric
motorcycles.

“Earlier this year, as part of our 10-year strategy, we reiterated our
commitment to build the next generation of Harley-Davidson riders, in part,
by aggressively investing in electric vehicle (EV) technology,” Harley CEO
Matt Levatich said in a statement.

“Alta has demonstrated innovation and expertise in EV and their objectives
align closely with ours. We each have strengths and capabilities that will
be mutually beneficial as we work together to develop cutting-edge electric
motorcycles.”

Harley says its first electric bike will be available for purchase in 2019.

Meanwhile, Alta, based in northern California, has been making electric dirt
bikes and enduro bikes since 2010. The company's Redshift MXR will travel
about 60 miles on a battery charge that takes about 90 minutes to complete.

The Redshift comes in two models — a street-legal "supermoto", and a
trail-ready motocross. Alta says the bikes could change the way people
commute during the week and how they ride on the weekend. 

“We believe electric motorcycles are the future, and that American companies
have an opportunity to lead that future. It’s incredibly exciting that
Harley-Davidson, synonymous with motorcycle leadership, shares that vision
and we’re thrilled to collaborate with them,” Alta Motors co-founder Marc
Fenigst said in a statement.

Terms of the deal with Harley, announced Thursday, weren't made public.

Another company, Logos Technologies of Fairfax, Va., has used an Alta Motors
bike in its work to develop an electric motorcycle for the U.S. military.

The "SilentHawk," is designed to produce minimum engine noise for use by
soldiers behind enemy lines.

Harley-Davidson might be using the name "Revelation" for the engine of its
new electric motorcycle, according to a trademark application.

Harley isn’t confirming it, but the company has filed an application with
the U.S. Patent and Trademark office for the name "H-D Revelation," in a
listing that includes electric drives for vehicles, engines for motorcycles
and batteries for vehicles.

Other Harley-Davidson bikes have similar sounding names for the engines,
such as “Evolution” for Sportsters and “Revolution X” for the Street 750.

One thing for sure: The new electric motor won't have the syncopated
"potato, potato, potato" rumble that resonates from Harley V-Twin engines, a
sound the company once tried to trademark.

The bike ought to be quick, with the prototype showing that it could go from
zero to 60 mph in under four seconds. Earlier, however, Harley said it
wouldn't bring an electric bike to market until the battery technology
improved to allow for longer driving distances.

When the company enters the electric bike market, it will have plenty of
company. 

Polaris Industries, the maker of Indian and Victory motorcycles, already has
an electric street bike that puts the company ahead in the new category of
two-wheel machines.

Named the Empulse TT, it looks like a high-performance sport bike without
the gasoline engine.

 Jaguar officially unveils production version of all-electric I-Pace:
240-mile range, 100 kW charging, and more

Jaguar has officially unveiled its production version of its first
all-electric vehicle: the I-Pace.

After already releasing many of the specs over the last year, we didn’t get
many surprises today, but the automaker did confirm all the production specs
and the price is apparently much higher than anticipated

To Jaguar’s credit, the production version looks very similar to the
concept, which is not often the case in the industry.

And just like the concept, the vehicle’s design is quite stunning and
already received a lot of praise. The exterior is just as slick as it was
when it was just a concept, while the interior received a more significant
update in the production version.

Here are a bunch of new images of the vehicle that they unveiled today as
part of their ‘global digital launch’ (the debut will be at the Geneva show
next week) ...

As for the powertrain, the company now says that the 90 kWh battery will
enable “an estimated range of 240 miles”, but they say that it is not the
EPA estimate.

The company has previously referenced an EPA estimate of “220 miles” on a
single charge.

Jaguar also clarified the vehicle charging capacity:

“Owners will be able to achieve a 0-80 percent battery charge in around
40 minutes using publicly available 100kW DC rapid charging facilities. Home
charging with a 230V/32A AC wall box (7kW) will achieve the same state of
charge (0-80 percent) in just over ten hours – ideal for overnight
charging.”

The vehicle is only offered in one powertrain version, but several different
trims are available with more features.

The company hasn’t released all the prices per market yet and says that it
will reveal more at the Geneva Auto Show next week. But Jaguar retailers can
apparently already take orders right now and the prices have been reported
in the UK:

Jaguar i-Pace S: £63,495 (~$87,000 USD)
Jaguar i-Pace SE: £69,495 (~$95,400 USD)
Jaguar i-Pace HSE: £74,495 (~$102,200 USD)

It’s significantly higher than originally anticipated, but it is about what
we have been expecting since a few leaks from Europe late last year.

Here’s Jaguar’s press release in full:

Re: [EVDL] Genset range extender

[Bill Dube via EV]

You really don't care about frequency. All you care about is staying 
below the maximum allowed battery voltage (or staying below whatever the 
signal on the BMS says is "to high".)


Thus, the generator speed (and the engine speed) can be whatever you 
wish it to be. Of course, you have to stay below the design limits for 
the generator rotor speed, but that is typically 3600 rpm or something 
close to that.


Large generators have some sort of field control, so you run the rpm up 
to the desired amount, then dial up the field current until the 
generator is either putting out the max current it is designed for, or 
the voltage has reach the max battery voltage.


Conversely, you can set the field current to some fixed value, and run 
the rpm up until you reach one of the above same limits.

doesn't matter that the head won't need to be on-frequency of 60Hz,
but forcing a gas engine to lug along at lower RPMs to make the
voltage more-or-less correct is going to be a strain on the ICE and
probably give him a big hit in available peak voltage, and by
association, available current into his battery pack/motor.

My inclination would be to stop encouraging him until he understand
the dynamics of what he is proposing. Series hybrids don't work well
in the best of designs, and he's throwing together a collection of
incompatible components that are sure to disappoint.

That's a good point. While I've seen gasoline gensets that ran at 1800
RPM, most do indeed run at 3600 RPM. This makes them smaller (but
noisier). Gasoline engines need to run fast to generate their rated
horsepower.

But if he's driving it with a car engine, most of them will happily run
at 1800 RPM for hours on end. You just can't get anything near its rated
horsepower. For instance, it might require a "100 HP" engine to produce
30 HP continuously.

Projects like this are always a trade-off between the "right" way, and
the "expedient" way to do it. Using what you have, in unconventional
ways isn't perfect, but may be good enough to get by.

[EVDL] MiniBMS & regular intermittent pulsing of loop?

[Jay Summet via EV]

I'm using a miniBMS system in my batteries, and the loop is connected to 
a Thunderstruck motors EVCC unit, which fires off a buzzer if the loop 
drops (indicating a low voltage event) while driving or turns off the 
charger if it's charging (indicating a high voltage event).



A few days ago I was driving around (short trip, pack no where near 
discharged, but not super close to fully charged either...) and the 
buzzer started to sound in a very regular pattern (about 1 second on, 
one second off).


I have never experienced this pattern of sounds before.

Sometimes at the end of a long trip I've gotten a low voltage event and 
the buzzer will sound briefly if I am drawing a lot of amps, but the 
buzzer would always stop as soon as I let up on the throttle.


This buzzing on/off/on/off continued while driving for another mile and 
when I was parked at home. I switched everything off and started it back 
up again (resetting power to the EVCC) and the pulsed buzzing continued.


I have a physical switch in my BMS loop for testing purposes, and when I 
opened it, the buzzer went from intermittent pulsing to solid on, so the 
EVCC was definitely still monitoring the loop.


I have a parallel pack trackr system that monitors the voltage of (every 
pair of) cells and everything looked normal on it, no pair of cells was 
low enough to be triggering a low voltage alarm.


I left the truck sitting for a few hours, and when I tried it again the 
intermittent buzzing had cleared and gone away. I've driven it a good 
100 miles since then with multiple charge cycles and haven't heard it again.



The other option is that the EVCC was signaling the buzzer in it's own 
pattern for some other type of fault (and then honoring the dropped loop 
signal to turn it on continuously), but the support staff at TSM felt 
that the pulsed signal was coming from the BMS loop, and the EVCC manual 
doesn't mention the buzzer sounding for anything other than a BMS loop 
event.


I'm just wondering if anybody has experienced this type of on/off/on/off 
loop signal with the miniBMS boards before, and if so, what it indicates?


Thanks,
Jay

Re: [EVDL] Genset range extender

[George Tyler via EV]

He only wants 30 kw, many engine could do this at lower rpm. Low rpm is not a 
problem as long as it is high enough to keep the oil pressure up and not cause 
vibration that may cause crankshaft failure.

Re: [EVDL] 3 phase range extender?

[George Tyler via EV]

I have done something like this, but on a smaller scale. Simple approach, run 
engine at 1/2 or 3/4 throttle, control excitation to control engine revs, if 
you want more power, REDUCE excitation! No regulator. Use 3 ph bridge, ripple 
frequency is 360 Hz depending on speed, and alternator inductance / impedance 
will reduce ripple. I think you will find ripple is acceptable.

Ahh, another useful answer.
Sounds like I have some experimentation to do.
