摘要： Battery monitoring techniques, which consume low amounts of power, are described herein. The battery monitoring techniques can be used when the host device (e.g., electric vehicle) is not operating, thus providing a time to use low power techniques. Measurement devices can measure system parameters when a host processor is off or in a low power mode using a heartbeat (HB) sequencing technique. Based on the HB message, the host processor can be alerted and awakened when a fault is detected.
