According to my research, batteries heat up on CHARGE more than on discharge (20% loss on charge and 10% loss on discharge).
Since the Volt uses a gas engine to charge the battery, the thermal management system is there mostly for charging the battery. On a "pure electric" like the volt, there's half as much energy lost to heat because it only discharges the battery while running.
The heat generated while charging the Tesla is considered waste because it happens while the car is sitting in your driveway not doing anything useful.
