It seems like thermal dissipation is the issue based on the grandparent post. An EV duty cycle using the built-in inverter won’t drain the battery in the same amount of time as high-speed charging would charge the battery. Perhaps there are also weight optimizations being made that limit bidirectionality of the inverter.
