Abstract
Systems and methods for charging and discharging a plurality of batteries are described herein. In some embodiments, a system includes a battery module, an energy storage system electrically coupled to the battery module, a power source, and a controller. The energy storage system is operable in a first operating state in which energy is transferred from the energy storage system to the battery module to charge the battery module, and a second operating state in which energy is transferred from the battery module to the energy storage system to discharge the battery module. The power source electrically coupled to the energy storage system and is configured to transfer energy from the power source to the energy storage system based on an amount of stored energy in the energy storage system. The controller is operably coupled to the battery module and is configured to monitor and control a charging state of the battery module.
