Electric vehicles
The electric drive system
The electric vehicle powertrain is powered by propulsion batteries. An electric
vehicle can have between 5 and 9 batteries.
The propulsion batteries have voltage class B (650 V), which supplies the
electric machine with 3-phase alternating current via an inverter.
The inverter is cooled with a water cooling system that also cools the direct
current converter. The direct current converter supplies the 24 V battery and
the vehicle's electrical system with 24 V voltage, which is converted from the
propulsion battery's voltage class B (650 V).
Overview of the BEV system components with voltage class B and their location.
