I wonder why they didn't' design a battery warmer into the case (at
least I assume they didn't). Seems that would have made a tremendous
difference in this case.

It’s not about whether or not the range is lower at lower temperatures, or what
you get in your car, but the accuracy of the claims being made by vendors of
zero emission technologies, and the commitments they make to customers.
BYD has some *great* products and is run by sone great folks, but this kind of
thing undermines the ability to transform fleets to zero emissions. It hurts
all of us working in the field when companies fail to meet the contracted
performance specs in their contracts.
And this is not the only similar horror story I’ve heard (though not
necessarily about BYD).
There is really no excuse for this. I will likely see BYD’s President later
this week, and will be expressing my disappointment.

Anybody that drives an EV, even a Volt that is a series hybrid realize the cold
temperature limitations, especially if you like to keep it warm and cozy on cold
days. I get 46 miles EV on my 2014 Volt on the best days, 24 miles on the coldest
nastiest days when I like to keep the car warm and toasty. Not a problem for me
since I commute 21 miles and plug in at work and I also plug in at home with 240V
so I never use gas. My best guess is this BYD range was estimated by sales and
marketing while the engineers were cringing in the corner knowing it was complete
BS, but the accounting department and upper management looking for higher returns
on investment realized range needed to be increased to meet contracts with bus
fleets that required the higher range, regardless of them actually needing them.
The good news is that the majority of bus manufactures see the writing on the wall
and are planning for an all electric fleet knowing that will be demanded soon by
many fleet orders. The immediate future for bus transit is electric and most
manufactures are already gearing up for that. With the advancements in batteries,
motors and controls, most fleet operators realize that electric is cheaper to
maintain than diesel or natural gas. The transitions will not happen overnight,
been when the people paying for overall cost of fleet operation is much cheaper on
electric they will switch, and it's coming soon < 5 years.

BYD installing wireless charging in Indianapolis to boost disappointing
range of its electric buses

Electric bus maker BYD has to install and pay for a wireless charging
infrastructure upgrade in Indianapolis after its buses experienced
“lower-than-expected distances on one charge” during testing.
Indianapolis Public Transportation Corporation IndyGo announced it reached
an agreement with BYD to get the new infrastructure. BYD will install
wireless charging hardware for the buses, in addition to three wireless
inductive charging pads along bus routes.
During testing, IndyGo realized low temperatures were causing a dramatic
dropoff in predicted range. Justin Stuehrenberg, IndyGo vice president of
capital projects and planning, said:
“We anticipated that vehicle range would depend on temperature, but the
contract requires a 275-mile range at 0 degrees. Our team identified several
options to address the issue and worked closely with BYD to determine the
most feasible resolution. At the same time, we made it clear to the company
they must be accountable to our contract. Numerous test days this spring
resulted in range performance at and above the contractually required 275
miles on a single charge. To date, the best range of any one test was 307
miles on a single charge.”
Many of those tests didn’t approach the required 275 miles, usually ending
somewhere in the low 200-mile range, as the range report from IndyGo
reveals. On one frigid day, range was limited to 152 miles.
