The main objective is to find a second use for batteries employed in electromobility after they have been used in the vehicle (second life). For example, as stationary storage for solar or wind energy. To analyze the residual capacity, the battery is first fully charged and then discharged in a controlled manner, for example, using an EA-PSB 10000, a 30kW bidirectional power source. The capacity (SOC) and state of health (SOH) are measured, and the energy is recovered and fed back into the electrical grid with an efficiency of over 96%.
Before batteries undergo final recycling, they must be fully discharged. The EA-ELR 10000 regenerative electronic charging system is ideal for this purpose. Even at 30 kW, the devices quickly extract residual charge from the batteries and return it to the grid with an efficiency exceeding 96%, thus significantly reducing operating costs.
