The motors are AC and it'll have a variable frequency drive (fancy inverter that changes frequency to drive the motor at the desired speed). Also provides the regenerative braking by running at a lower speed than the motor.

DC motor EVs are not really a thing any more, outside of hobby conversions.

Low power VFDs are dirt cheap these days, but a 65kW one would run a few thousand. A brand name industrial spec one in that power range would cost $5-10k USD.

Charging from home is AC, and IDK maybe it also contains the charging control for DC?
Anyways the inverter alone is generally upwards of 1000 Euro.
