Abstract
Systems and methods for providing a battery module 110 with secure identity information and authentication of the identity of the battery 110 by a host 120. In one embodiment, the system for providing a battery module with secure identity information includes: (1) a tamper resistant processing environment 200 located within the battery module 110 and (2) a key generator configured to generate a key based on an identity of the battery module 110 and cause the key to be stored within the tamper resistant processing environment 200.
