The BaBa-PV project focuses on developing a charge controller to link the Batteries of e-bikes and e-power tools with micro-photovoltaic systems ("Balcony PV") in such a way that the accumulator systems can be charged during the day with the help of photovoltaics, while in the evening and night hours the electrical energy stored can be supplied to the household grid. This significantly increases the degree of self-sufficiency of the participating households and at the same time is an interesting second-life application for the battery systems. In addition, the micro PV system can be used as a charging station for rechargeable batteries (boost mode); the parallel use of both operating modes is also possible (dual mode).
