Volkswagen previewing mobile quick charging station; trials in 2019, production in 2020

Green Car Congress

Each charging station enables DC quick charging with up to 100 kW. If, however, it is permanently attached to the power supply with up to 30 kW via alternating current, the battery pack perpetually recharges itself. They can be set up anywhere as required—with or without connection to the power supply.

Volkswagen introduces near-series design study of the MEB-based flexible quick charging station at Geneva

Green Car Congress

Connected to the grid or even off-grid, the station can charge up to four electric cars simultaneously, based on the principle of a ‘power bank’, two with DC quick charging. The charging station can be used as interim storage for eco-power; however, when connected to the mains power grid, it becomes a permanent charging point.
