Abstract
Electrified vehicle battery overcharge protection techniques monitor an intelligent battery sensor (IBS) current signal via a controller area network communication (CAN-C) bus and an output current of an auxiliary power module (APM) when the IBS current signal is unavailable. A controller then intelligently adjusts charging of the battery system to be battery current-based, battery temperature-based, or at predetermined constant value, based on a determined validity of the IBS current signal, the measured battery system current, and an awake/asleep status and responsiveness of the CAN-C bus.
