DC coupled charging system with charging stations, BESS, and solar panels

Compared with a traditional AC coupled charging system that connects solar panels through inverter, energy storage through PCS, and charging station through AC/DC modules, an ALL-DC charging system can potentially reduce energy loss from up to 20% down to 2%. In the mean time since there is not so much wasted heat, there is little need to cool down the whole system. This can also greatly eliminate the noise that is produced in the cooling process.
