Abstract
A battery management system may include a host microcontroller, operated in accordance with a first clock signal. The battery management system may also include a first sensor, which may be configured to measure a first value of a first group of one or more cells in a battery system. A first AFE circuit may include a first pulse-width modulation (PWM) controller, which may be configured to at least one of enable or power on the first sensor while a first PWM signal from the first PWM controller is in a first state, and may be configured to at least one of disable or power off the first sensor while the first PWM signal is in a second state. The first AFE circuit may also include a first storage register, which may be configured to receive a representation of the first value measured while the first sensor is on and enabled.
