Abstract

See full text

Communication between an information handling system and battery has improved reliability by repeated communications of information from the battery using different commands from the information handling system. A battery management unit responds to a first command from an information handling system by sending information stored at a first address associated with the command and then saving the first address at second address. A power manager of the information handling system sends a second command having the second address to the battery management unit. The battery management unit responds to the second command by retrieving the first address stored at the second address, retrieving information stored at the first address and sending the information to the power manager. The power manager restricts operations of the battery, such as charges or discharges, unless the information received in response to the first and second commands matches.
