Maintenance-free and efficient
At least as important as the cell chemistry is the module. A single module contains 7 or 14 Li-NMC cells. The module gives the cells the shape of a battery. Our basic principle when developing them was to achieve a maintenance-free and efficient module.
We use spring tension instead of nuts and screws, and this makes the battery maintenance free. In contrast to using screws, the cells always retain their maximum clamping and there is no need to regularly check the springs.
Moreover, the unique structure excludes any ‘foreign material’ from between the tabs. Our battery thus has maximum efficiency, and there is virtually no loss of energy. With 1C/1C, our battery module has more than 95% efficiency.
The modules have been executed in a waterproof IP65 casing.
