The KontaktCharger is the solution for efficient and economical conductive charging of lithium-ion vehicle batteries in intralogistics.

With two voltage ranges and three power classes each, the KontaktCharger covers a wide range of applications. The application range of the KontaktCharger includes both 24 V applications and 48 V applications, each with 3 different power classes. This means that charging capacities from 2 kW to a powerful 9 kW can be covered.

Technology and efficiency

The device is operated via a color, graphic control panel (touch screen) in the upper front area of the housing. The operating menu follows a hierarchical structure consisting of a start/status page and setting pages for the various operating modes and error displays. Either the standard CAN 2.0B or the standard CANopen are available as communication interfaces to the battery. Battery information is also shown on the charger display in BMS operating mode. As an alternative to the active exchange of information via CAN interfaces, the KontaktCharger can also be started and stopped manually or via a simple pilot contact function.

In manual operating mode, the charging current and end-of-charge voltage are preset via the menu; in automatic or BMS mode, the charging parameters are set by the battery management system. All electrical interfaces are located under a maintenance cover on the front of the device and are easily accessible via four quick-release fasteners. The KontaktCharger is designed for indoor use with a permissible ambient temperature of 5°C to 40°C. In the temperature range above 30°C, the output of the KontaktCharger is gradually reduced (de-rating) to protect against overheating. The maximum reduction at 40°C is approx. 10% of the rated power. The KontaktCharger has active fan cooling, with the air flowing horizontally through the device.
