Storage System
Energy Delivering System
High efficient power grid200-450V DC at 40kW
Batteries
Very high efficiency and reliability due to:- Direct coupling of the motor electronic to the fuel cell/energy source, without DC/DC- High reliability due to direct, parallel use of an optional battery
- Power overboost for critical situations- Fuel cell in max. efficient mode- Very Low Cost Components!
