I imagined that cooling wasn't that much of an issue since they don't seem to prioritize it a lot.
(I get that there are other factors, but regardless they feel they have the luxury to do without it)
- jdietrich 7y agoAn electric motor is drastically more efficient than an internal combustion engine and so produces much less heat, but it's more difficult to get the heat out of the motor. You don't need a big radiator with lots of airflow to cool an electric motor, but you do need an intelligently designed heat exchanger in the motor unit.
- leguminous 7y agoThey still have intakes and radiators, maybe just not quite as large. Plus it seems to be stylish to put giant grilles and even fake vents on some cars nowadays. Here's a great video showing the Chevy Bolt's cooling and heating systems: https://m.youtube.com/watch?v=_ILkLUE3Zxc https://m.youtube.com/watch?v=_ILkLUE3Zxc This channel has some awesome, in-depth videos. There is a whole series going over the Bolt's components, including the drive unit and battery.
