On-board charger OBC 22K
Compact and efficient high-voltage charging up to 850 Volt.
Thanks to the state-of the art SiC switching technology, the REFUdrive on-board charger is particularly efficient and achieves an efficiency of over 96 %. The device is water cooled, it allows a very wide ambient temperature range. The device contains a galvanic separation.
Flexibly scalable and configurable.
The on-board chargers can be configured in parallel and are therefore scalable. In pair mode, two on-board chargers share a one 63 A/400VAC inlet. The operation via an AC charging wallbox is possible in accordance with EN 61851-1:2011. As an option the on-board charger can also be connected in parallel up to 8 units and thus scaled to higher charging power.
The REFUdrive on-board charger is equipped with the interfaces Modbus and Ethernet. Thus it is flexibly controllable and configurable. The charger can be controlled remotely via the diagnosis software.
