Authorization to charge
Operation of the charger is possible with or without authorization. The authorization to charge can
be based on RFID or credit card payment methods. Operating a charger with authorization re-
quires a subscription to a back office. Authorization can either be an ABB supplied standard solu-
tion, or from an external company offering authorization solutions via OCPP.

Output Power vs. Output Voltage curve
The curve below shows the output power vs. the voltage output of the charger, reflecting that the
charger can operate at the 22.5kW power range for both 400VDC and 800VDC architecture battery
packs.
The DC Wallbox can output 22.5kW continuous power, with 24kW peak output capability.
Note that the continuous output power is limited when ambient temperature is higher than the
operating temperature range of -35 °C to +45 °C: ABB’s overheating protection algorithm will de-
rate the unit linearly up to +55 °C (this refers to location when charger is not exposed to direct so-
lar radiation).
In the Vout ranges 480 / 675 Vdc and 150 / 350 Vdc there is an automatic current limitation.
The above curve refers to the 240V L-L AC supplied 1-ph version and 3-ph versions of DCWB.
For the 1-ph 208V L-N AC supplied one has to be considered the input max current limitation to
100A that limits the max output power to 19,2kW@208 Vac [ref. to exact value mentioned in
datasheet].
