Seeing EVs touted as the future, the abandonment of discussions regarding cold start idle etc...and that cranking batteries may be down by over 50% on these extreme mornings.

Got me wondering about EVs in the US, particularly the cold.

First up, is it just lead acid that will lose 50% in the extreme cold ?

Secondly, heating how to ?

"In general, Lithium-ion cells cannot be charged below 0 degrees Celsius, which would theoretically prevent charging in cold environments. To overcome this cold weather charging obstacle, the Roadster is designed with a heater to warm the cells (when plugged in) to an appropriate charging temperature. If there were no battery pack heater, drivers living in cold environments would have difficulty charging and experience stunted driving performance.

Likewise, the cells are designed to operate in high-temperature environments. High-performance driving is possible in even the hottest environments of the world. If the temperature rises above a set threshold, the air conditioning unit sends chilled coolant through the pack. Similar to the radiator fan of ICE-powered cars, the chilled coolant continues to circulate after the motor has been turned off to keep the temperature at an appropriate level. Cooling the pack enables a driver to quickly charge immediately after hard driving in hot climates. Without such a cooling system, recharging in hot weather would be delayed after each drive."

Leave car plugged in, start car and turn on the heat / defrost.

Once car is warm inside, (60 - 70) unplug and depart.

Some have a "Departure Time" feature that will pre-warm the car up and have it ready at a preset time...

Don't run the heat unless necessary, use the seat heaters. It's a lot less current draw...

I'm a bit paranoid. I brought my LiCoMn batteries inside. Well they are bike batteries so that was easy.

Most of them have battery warmers, but range will still suffer.

Automakers love to brag and show videos of how they test their cars in Death Valley and in the Arctic. I would like to see the same with EVs, particularly in the Arctic. Let's see how warm an interior gets when it's -40 outside. wink

The fit ev suffers really bad. Goes from like 60 mile to 15 mile range

GM has had issues with the electric heating system in the Volt. Owners have complained of woefully inadequate heating during EV driving mode in cold temps. The only solution is stronger electric heaters with the higher draw/lower range penalty they exact (not sure if the newer models have addressed the heating issue). It's predicted to get to -25F here by tomorrow night...seat heaters don't cut it when it's that cold (though they help a lot during milder weather).

There's always a good old fashioned gasoline fired heater:



Oh yeah, there's the issue of getting gasoline to it, minor problem. grin

So for good mileage you have to go without heat.. Hybrids are great! LOL

...or you can improve insulation, AC behaviour and waste heat management to get the heat up. Traditional cars have plenty of waste heat to use for heating purposes, so it hasn't gained much attention until now.

Starting at -30, insulation doesn't gain much while the interior thermal mass gets up to temperature...and all the heat that is required to do so comes from the grid...which has already given up it's inefficiencies.

This is correct, but it also shows yet again that hybrids are still a work in progress. Great concept. I'm sure they do excellent in moderate temps where the AC and heat don't have to be ran.. but for the person who lives in the colder or hotter temps they might as well be driving a diesel Jetta for fuel economy.

I'm surprised some didnt install wood stoves in the back seat,so mileage wouldnt suffer.Oh yea,theres the issue of the emissions from burning the wood...EPA wouldnt approve...
