Example of high-voltage battery specifications: 

Specifications  Energy bias version Power bias version
Nominal capacity 8.9 kWh 7.7 kWh
Nominal voltage 386 V 386 V
Pulse power 77 kW 310 kW
10 s power 71 kW 220 kW
Continuous power 39 kW 74 kW
L x H x W 1166 x 685 x 181,6 mm

Variants can be connected in series up to 1000VDC.

For hybrid systems

Proventia high-voltage battery systems facilitate peak power management in hybrid applications. This allows smaller combustion engines to be used. Downsizing the engine enables reduced fuel consumption and total ownership costs less COemissions.

For fuel cell applications

In fuel cell scenarios, Proventia high-voltage batteries consistently provide fast, reliable power when required. Typically, fuel cell operation is optimal when run at fairly constant power, while the battery needs to provide a fast load response. Our batteries excel in these situations, providing high-power capability and maximizing the fuel cell’s lifetime.
