Table 1. Example of dynamic and static charging power management
Charging power unit with 4 x 50 kW power
modules (200 kW)
Output to 4 charging
points
Dynamic output (Ds4) @ 400 V 25–200 kW
Dynamic output (Ds4, adaptive voltage) @ 800 V 50–200 kW
Dynamic output (Ds4) @ 667 V 25–200 kW
Static output (S4) @ 500 V/800 V 50 kW
Dynamic charging can operate in two modes:
•
Democratic mode where the charging power is distributed evenly to all
charging points in use. See
Figure 1.
• Priority mode where charging power is distributed in order of priority.
The priority type is set in Kempower ChargEye and can be customized
to your needs. For example, arrival priority (FIFO, first in first out) is where
the first arrival gets the most charging power (as requested by the
vehicle). When the first vehicle leaves, the freed capacity is shared in
arrival priority with the remaining vehicles. See Figure 2.
