Re: [EVDL] EVLN: 30% Range Boost from EV-specific FPCU Controller chip

2018-03-20 Thread Cor van de Water via EV 
Simple, pure physics.
If you can improve 30% (ie, give 30% more range)
then there needs to be at least 30% waste in the first place.
Waste always shows up as heat, as Lee likes to point out:
Heat is the indicator of the (lack of) efficiency.
So, if you have an EV that needs roughly 25kW to drive freeway speeds,
Then you expect in the order of at least 10kW of heat to be produced
*if* there is so much loss.
This would mean that you need a significant amount of cooling, since
this volume of heat is
about the heat of  7 plug-in space heaters combined (each drawing about
12A at 110V)
Now remember the installation practice of the Zilla controller, where
you are guided to use
something equivalent to a tiny aquarium pump and a bottle with water,
not even a
radiator needed as there is so little heat to get rid of anyway.

I have driven several EV trucks for many years as daily driver.
The first thing I usually do is to disable the radiator fan, if it is
running constantly, since there is simply
so little heat that there is no need for a big fan blowing through a big
radiator - which was a left-over
from the ICE factory conversion where you need to get rid of about 100kW
of waste heat.
The only exception is if the controller is used for charging, because
then even a couple hundreds of Watts
dissipated over many hours can warm up the controller to a point that it
may be useful to cool it.

The other example is the Prius's inverter water pump which has a
tendency to fail silently.
The only indication that you actually have no cooling for the inverter
is not that the car is not driving,
but that on a hot day with a longer drive, it may start limiting power
or the 12V battery conks out,
because the DC/DC (which shares the cold plate with the inverter)
overheats and disables itself.
The fact that you can keep driving the vehicle without water cooling,
tells you that the inverter
actually produces very little heat or else it would fail soon.

My (cynical) view on the claim of 30% is that they are probably not
claiming to increase range by 30%
but that they reduce the waste by 30% by paying more attention to the
power needed by the
controller's own operation.
This means that if you have a 90% efficient vehicle they reduce the 10%
waste by up to 3% so the
vehicle may now be up to 93% efficient.
For a car with 80 mile range, this means that they add "up to" 2.4 miles
of range.
Not insignificant, but not as spectacular as their
claim-disguised-as-question
"Can this controller add 30% range?" because the simple answer to that
is "No."

You can also derive it from the bogus argument in their article that
they improved the
efficiency by using a faster controller, because (as they claim) the
industry was using
microcontrollers designed for ICE and they use a specific automotive
design.
Eh, not only does that claim make no sense whatever, but making a
controller faster
usually means that it consumes *more* power, not less.
But hey, who am I to judge?
Let them show some independent test results and we will know.
For now, it is just investment-baiting fodder for all I can determine.
Cor.

Maybe this design could improve range (efficiency) that much if you
substituted it for a creaky old SCR controller, or for a controller
really badly matched to a sepex or induction motor.  But I don't see
that kind of waste in modern EV drives, thank goodness.

2018-03-20 Thread Collin Kidder via EV 
Exactly. A modern EV drive train could be 85-90% efficient from
battery to the road. To improve range by 30% you'd have to get more
than 100% efficiency. There just isn't room for that level of
improvement in the electronics. Now, maybe you could add 30% by
reworking the body to be more aerodynamic and removing weight. But,
that's not what they're claiming. Always be suspicious of claims that
defy logic. The best they could hope for is to reduce the inefficiency
by 30%. I mean, I'd believe they could take a 90% efficient drive
train and make it 93% efficient. That's 30% less inefficiency but
you'd be hard pressed to notice the difference.

Silicon Mobility, a provider of control solutions for the automotive
industry, recently released a product that promises drastic performance
improvements for electric vehicles (EV) and hybrid vehicles. The company
developed a novel semiconductor architecture, a Field Programmable Control
Unit (FPCU), which it claims can extend EV range by over 30 percent on the
same battery.

The FPCU integrates a standard ARM Cortex-R5F processor with Silicon
Mobility’s AMEC subsystem. The latter consists of a key component, the
flexible logic unit (FLU) that handles real-time actuator and sensor
control. The FLU is what puts the field programmable in FPCU as its
flash-based programming allows it to be fully or partially reprogrammed in
the field. The FPCU also incorporates a SILant functional safety
architecture, classified as Automotive Safety Integrity Level D(ASIL-D),
which corresponds to the highest safety requirements in an automotive
product.

Silicon Mobility’s first FPCU is the OLEA T222, which is available for
application development but has not yet been qualified for the automotive
market. David Fresneau, Silicon Mobility vice president of marketing and
business development, said the qualification will be finalized by the end of
the month, with volume production of the OLEA T222 set for the beginning of
next year.

The OLEA T222 comes with a design framework and software library for
original equipment manufacturers(OEMs) to implement inverter control, DC-DC
control and more. The software and hardware code for the FPCU can be
generated using MATLAB and Simulink.

How will the FPCU help boost EV range so drastically? To put it simply,
Silicon Mobility claims that OEMs have been using inadequate
microcontrollers, originally developed for internal combustion engine
control, in their hybrid and EV applications. By designing its FPCU
specifically for automotive powertrain control, Silicon Mobility believes a
software bottleneck has been removed. It claims a 40x acceleration on data
processing as opposed to a reference automotive microcontroller, as well as
a whopping 180x reduction in power consumption. Put together, they claim
this can lead to a 32 percent increase in hybrid and EV range.

“We are completely committed to electrification,” Fresneau said.

If the FPCU lives up to its promise, it has the potential to help pull a big
thorn from the EV industry’s side: battery range. This has become one of the
key metrics by which any EV is judged, and its prominence in the eyes of
potential EV consumers has even been given a name: range anxiety.

The ability to boost range by 30 percent simply by swapping one controller
for another would be a no-brainer for EV manufacturers and could do a lot to
accelerate consumer EV adoption.Silicon Mobility’s commitment to
electrification seems evident, although it remains to be seen if its FPCU
can follow through on this commitment.

Tesla’s second-generation Roadster is going on something of a tour. The
upcoming electric supercar, set to hit the roads in 2020, was spotted at the
Nevada-based Gigafactory on Tuesday after a month of appearances around the
country.

An Instagram user called Stephen Roth shared four images of the car on his
personal page, demonstrating the under-development vehicle in a show area.
The spotting comes just over a month after similar sightings at its Palo
Alto headquarters and the Fremont test track.

The new model looks like it could turn heads all over again. With a 200
kilowatt-hour battery, the car can run for 620 miles on a single charge at
highway speed. The new Roadster can reach a top speed of 250 miles per hour,
accelerating from 0-60 in a world-record 1.9 seconds thanks to a Plaid mode
— a reference to cult ‘80s movie Spaceballs. Pre-orders are live, and the
company is asking for $50,000 to reserve the $200,000 vehicle.

The car, unveiled by CEO Elon Musk in November 2017 alongside the Tesla Semi
electric truck, is set to improve on the original Roadster that launched in
2008. The new model has big boots to fill, with its predecessor both the
first car produced by Tesla as well as the first all-electric car to travel
more than 200 miles per charge.

The original was also the first to enter space, after Musk said goodbye to
his personal Roadster in February when it went into orbit on a SpaceX
rocket.

It’s not just the Roadster that Tesla has been testing. Prototype models of
the semi truck due for launch in 2019 have been spotted around the company’s
headquarters, with one driving past the UPS headquarters with a whisper
quiet movement. Musk also shared images last week of two semi trucks ready
for the open road.
