SYSTEM FOR SWAPPABLE BATTERY MODULE CHARGING AND DISCHARGING

The charging and/or discharging of a set of swappable battery modules in a battery system is carried out automatically using a set of charging and/or discharging control switches linked in a sequential charging and/or a discharging control chain. The charging and discharging of the set of battery modules can be done sequentially or in parallel, and is hardware-based with minimal software/firmware involvement. The system is scalable and automatically reconfigurable for use in an infrastructure and/or in an electric vehicle. The swappable battery modules may be positioned in the battery slots or butted together in the battery system.
