...The first car was far different. Less efficient, no hub motors, the solar only ran the BMS which was active instead of air cooled built into the body frame, really it's an entirely different car except for the shape.
Their first cars were gassers but with amazing MPG figures, correct?
As for the word
BMS, to me that means Managing the battery by controlling Max charge and discharge currents, max/min Voltages for its SOC range, Cell Balancing, and communicating to displays and other systems, and probably other things I don't understand...
TMS is Thermal management. A separate function.
I think we should start using this distinction.
I don't understand how this car has coolant based TMS and claims to 'use the body frame' as it's heat exchanger. The body is composite material, not a good heat transfer material.
(I've seen experimental aircraft where the coolant lines are bonded to the inside of the aluminum skin as the heat exchanger.)
And if it's painted black, the
body is solar heating some of the time.
And when operating in 100°F conditions where is the battery pack heat supposed to go?
And when it's -7° what will warm the pack to a decent operating temp?
(We've already questioned if this is a winter capable car on snow covered roads...)
The Bolt and other EV's have a coolant based TMS that is freon cooled and resistance heated.
Isn't this sort of TMS needed for an EV? It is for me to take it seriously.
Side note: I bought a second 1st Gen Insight after a stint with TDI's.
But when I remembered it doesn't have the cargo space for luggage for two on the way to the airport, it had to go..
What good it an ultra efficient EV two seater if you can't pack for road trips with it?
Maybe a motorcycle trailer?
