Technical Datasheet

Kempower Satellite Version 2

The Kempower Satellite DC charging system is the optimal solution for public charging and other sites that need multiple fast charging outputs.

Satellites are connected to Power Unit. One Power Unit can simultaneously provide energy for up to 8 DC charging outputs with 800 VDC systems and up to 6 outputs with Adaptive Voltage systems covering both 400 VDC and 800 VDC charging.

The maximum available charging power of the system is 600 kW, depending on the Power Unit version. Each output can deliver up to 320 kW to the charging Satellite when using the optional 400 A charging cable.

Kempower Satellite is available with CCS1, J3400/NACS and CHAdeMO vehicle connectors, including configurations specifically for NEVI-funded charging sites to provide drivers the flexibility to choose the connector that matches their vehicle.
