Abstract: A battery management system includes battery management circuitry configured to be coupled to one or more battery modules. The battery management circuitry includes a secure element storing cryptographic information that enables the battery management circuitry to communicate securely with an external server as part of installation of a new battery module coupled to the battery management or removal of a battery module already coupled to the battery management circuitry.
