The HE battery series is based on a high energy density battery cell. This means more energy in less weight. The integrated battery management system brings the highest standard on safety and gives insight in the status of the battery. Flexibility in system configuration is created by a modular design. On a system level a voltage range of 25.2 V up to 465 V and a capacity range of 2.5 kWh up to 720 kWh can be created with the 25.2 V modules.
The new E-rack system is a modular energy storage system based on the HE Series. Each E-Rack can hold two HE 300 Ah battery modules. The stackable design gives flexibility and scalability. The racks can be mounted on top of each other up to 4 high to create 60 kWh of energy storage. Connecting multiple racks in parallel will extend energy storage capacity and add redundancy to the system.
The E-Rack system can be used for solar energy storage applications, peak- shaving, backup systems and mobile energy supply. The system is scalable from small residential systems up to large industrial peak shaving systems of several MWh.
Protecting, monitoring and controlling a battery system is very important to create a safe, reliable and easy-to-use system. The MG Master LV is the safety and control unit of the battery system in the range of 12 V to 96 V. It protects the connected battery modules against over-charging, over-discharging, over-temperature, under-temperature and controls the balancing of the battery cells. Besides a safety function, the Master LV monitors and tracks other important parameters to give insight in the battery status and energy consumption. The integrated DC distribution, fuse holders and safety contactor make it easy to install and require less cables and external equipment.
