Much of that heat is dissipated by the charger unit, not the car. The charger has massive heat sinks and fans etc, so not really a big deal!
The rest is just warming up the battery, which is a big heavy block which can store a lot of heat. This can be dissipated over time, which is actually very useful in winter! (heat pump scavenges battery heat to warm cabin, etc)
