An Off-grid Electric Vehicle Charging Station Solution with Clean Energy Power Supply to German Customers

Our German customer wants to install a DC fast EV charger in his factory, but there is no grid power supply. For this reason, we provide the customer with an off-grid EV charging station solution, that is, using a mobility energy storage system to power the charging piles. The energy storage system stores electrical energy in the photovoltaic power station and then goes to the charging station to release the stored energy to the charging pile to provide power for electric vehicles. This innovative move enables charging piles to be powered independently, no longer dependent on the power grid while ensuring the continuity of charging services.
