This invention provides a method of energizing electric vehicle (EV) power train with multiple and independently controlled battery packs. In this method, an EV can have one or more battery packs installed, only limited by the EV's physical spaces of the battery pack connector. All battery packs are interchangeable. Each battery pack has its battery management system (BMS) software and can either provide energy to the EV concurrently or individually. A typical embodiment of the invention comprises of a battery pack controller, a battery pack connector, a battery pack acting as the master (master battery pack), and optional slave battery pack(s). The battery pack controller connects electronically with the battery pack connector. The master battery pack, and optional slave battery pack(s) are mounted in the modular battery pack connector. The battery pack controller whose source is from the BMS of the master battery pack manages the charging and discharging of the master battery pack and optional slave battery pack(s).
