3.3. DCBM 400/600 in EVSE
This part describes the integration of LEM DCBM into different kind of Electric Vehicle Supply
Equipment (EVSE). Two examples are given: a 50 kW power class system, and a 350 kW power
class system.
3.3.1. DCBM in 50 kW EVSE
The following figure presents the typical structure used in 50 kW power class charging systems.
These systems use to offer multiple output cable connectors (i.e. Combined Charged System and
CHAdeMO). Several AC to DC converters deliver power to either one or the other output cable.
Power relays select the output cable.
