Just out of curiosity!,
What heat exchangers/radiators are in the nose of the Spark EV?
The Bolt may be similar.
The Volt's cooling/heating system is thoroughly explained in this article: http://gm-volt.com/2010/12/09/the-chevrolet-volt-coolingheating-systems-explained/
It's a complex system. 2 and 3 way coolant valves and such...
This image is from there:
Is the Spark EV similar minus the 'engine cooling'?
The reason I ask is when at a DCFC in the summer the AC compressor is running and there is a 'freon-to-battery coolant' heat exchanger. You can see that small silver block on the right side under the hood with coolant and freon lines connected.
But in cold weather the AC compressor would not have to power up if there is a typical 'radiator' type heat exchanger for the battery coolant loop.
Do the electronic units coolant loop(inverter and battery charger) AND the battery coolant loop have radiators of their own?
Or are these systems only cooled with the AC freon system and those small block-type heat exchangers?
