Power transient response is 3x faster than 12V battery.

You may wonder why does an EV need a conventional battery when there’s a 400V or 800V battery already in the vehicle to power the motors? Today the 12V or 48V batteries power all the other systems in the vehicle, but they add cost and weight and take up valuable space. Why not remove the 12V battery and use the 400 – 800V battery to power everything in the car?
