Fast charging capability of MEB battery pack is that 100kW can be charged within 30 minutes for range of 290 km (WLTP)
The structure of the Battery Pack
one battery module consist of 24 cell, to create a battery pack these modules are put together, the number of the modules put together depends on the size of the battery needed.
in the ID.3 12 battery modules are put together via battery connector to form a battery pack system, and to get a 408V DC. in a normal Alternating current system the battery is charged with 11kW of power and in a direct current system charging power becomes 125kW.
