With increasing operating time, lithium-ion batteries become less effective and need to be replaced in the vehicle. The old batteries then begin a second life or are finally recycled and completely discharged. EA offers a wide ranging product line for initial battery production, recharging, second life test and final recycling. Its bidirectional power supply EA-PSB 10000 and regenerative electronic load EA-ELR 10000 provide safe and sustainable preparation of discarded batteries – with 96% regeneration efficiency.
If the storage capacity of the lithium-ion battery systems is no longer sufficient for use in e-vehicles, residual capacities may well be available for second-life use as energy storage for solar power or wind energy. With the EA-PSB 10000 bidirectional power supply, the batteries are tested for their remaining capacity by charging them to almost 100% and then discharging them again.
At 30kW in a 4U package, the EA-PSB 10000 bidirectional power supply offers the highest power density on the market. Up to 1.92 MW is possible in a rack system, which means that mass testing is also possible without any problems. In addition, EA-PSB 10000 can seamlessly switch between operation as source and sink, which offers additional time savings.
The true autoranging capability of the PSB 10000 guarantees the maximum possible charge and complete discharge of the batteries through the high load currents even at voltages below 2-V. Its ability to restore voltage up to 96% efficiency makes the EA-PSB 10000 a highly cost-effective solution.
