Abstract
A battery management system can have a portable electronic device for providing electrical therapy to the body of a patient responsive to the occurrence of a treatable condition. The portable device can have a rechargeable battery, memory, data processor for determining available operating time for the portable device prior to recharging, and a display panel, or alarm, to inform the patient of, inter alia, available operating time. The portable device data processor can obtain and record data regarding the patient, the battery, and the portable device operational status. The battery management system can also include a rechargeable "smart battery," of known design, which has an integral processor and memory capable of monitoring and updating the status and condition of the battery. The portable electronic device can communicate with and update the operational characteristics stored by the smart battery. The smart battery can be recharged using an appropriate conventional recharger. The portable electronic device can include battery maintenance capabilities to perform tests on the smart battery to independently evaluate the condition thereof. The portable electronic device can also …
