Beschreibung
Zusammenfassung:	A method for charging an electric vehicle is provided. Aspects include configuring a switchable battery of the electric vehicle in a fast-charging configuration by connecting a first battery pack of the switchable battery to a first charging source and a second battery pack of the switchable battery to a second charging source and obtaining one or more characteristics of the first battery pack and the second battery pack. Aspects also include identifying the first battery pack as a master pack and the second battery pack as a follower pack based on a determination that the first battery pack has a lower voltage level than the second battery pack. Aspects further include adjusting a duty cycle of a switchable active load connected in parallel to the follower pack based on the one or more characteristics of the first battery pack and the second battery pack.
