发明名称 Battery with non-volatile memory for LMR portable radio applications
摘要 An apparatus and method for monitoring and storing a status of a rechargeable battery pack in which the battery pack status is monitored by a device while the battery pack is functionally connected to that device, and then periodically updated to a non-volatile memory in the battery pack. The non-volatile memory may be connected in power isolation from the rechargeable cells, thereby ensuring that the battery is not drained during long periods of storage. The battery pack may also have a latch, which has to be released in order to remove the battery pack from any device to which it can be functionally connected. Releasing the latch may cause the battery status to be written to the non-volatile memory, ensuring that the battery's memory has up-to-date battery status information, whenever the battery is removed from the device regardless of any scheduled data writes.
