  • Rechargeable energy storage system with different cell chemistries
    Patent number: 11575173
    Abstract: A rechargeable energy storage system includes a battery pack and a battery controller. The battery pack has a voltage current temperature module and multiple battery modules. Respective battery modules have multiple battery cells and are operable to store a module identifier that encodes at least one parameter of the battery cells, receive a configuration request from the voltage current temperature module, and transfer the module identifier to the voltage current temperature module in response to the configuration request. The battery controller is in communication with the voltage current temperature module and is operable to send a status request to the voltage current temperature module, receive the plurality of module identifiers from the voltage current temperature module in response to the status request, and compare the module identifiers to determine either a match or at least one mismatch among the module identifiers of the battery modules.
