A method for charging an electric vehicle is provided. Aspects include configuring switchable batteries of an electrified vehicle into a fast charge configuration by connecting a first battery pack of switchable batteries to a first charging source and connecting a second battery pack of switchable batteries to a second charging source and obtaining one or more characteristics of the first and second battery packs. Aspects also include identifying the first battery pack as a master battery pack and the second battery pack as a slave battery pack based on determining that the first battery pack has a lower voltage level than the second battery pack. Aspects also include adjusting a duty cycle of a switchable active load connected in parallel with the slave battery pack based on one or more characteristics of the first battery pack and the second battery pack.

    提供了一种用于对电动车辆充电的方法。各方面包括通过将可切换电池的第一电池组连接到第一充电源并将可切换电池的第二电池组连接到第二充电源并获得第一电池组和第二电池组的一个或多个特性来将电动车辆的可切换电池配置为快速充电配置。各方面还包括基于确定第一电池组具有比第二电池组更低的电压水平来将第一电池组识别为主电池组并且将第二电池组识别为从电池组。各方面还包括基于第一电池组和第二电池组的一个或多个特性来调节与从电池组并联连接的可切换的有源负载的占空比。
