Removable battery pack gives high speed EV charger flexibility
Munich start-up Jolt Energy has launched a 160kW high speed charger for electric vehicles with a replaceable battery pack for installation without a grid connection

A grid connection is not necessary, because MerlinOne’s integrated 200 kWh battery storage provides the power. When the battery is almost empty, the complete MerlinOne charging station is exchanged for a fully charged unit.

For the transport, Jolt and Swedish company HIAB have developed a special truck called MerlinTruck with an automated crane and carrying system, which ensures the swap process is completed in under five minutes. 

MerlinOne has two additional operating modes both of which involve a grid connection. When connected to the low voltage grid, the integrated battery storage operates as the basis for fast charging. It is continuously charged via the power grid and releases the electricity as needed in a very short time. This not only enables high-power charging at low voltage, but also avoids costly network expansion, for example on city streets or at gas stations. The third option is to connect the MerlinOne to the medium voltage grid, allowing the charger to operate continuously at high-power, while at the same time providing charger-to-grid (C2G) services.
