Abstract: At least some aspects of the disclosure provide for a system. In at least some examples, the system includes a microcontroller, an energy storage element, a monitoring circuit, and a communication bridge. The monitoring circuit is coupled to the energy storage element and configured to determine whether a fault associated with the energy storage element is present, generate an indication of the fault when the fault with the energy storage element is present, and transmit the indication of the fault. The communication bridge is configured to receive the indication of the fault and assert a fault signal and transmit the fault signal to the microcontroller.

Abstract: A battery management system includes a set of N battery modules coupled together in series, a set of N battery monitors, and a controller. Each battery monitor in the set of N battery monitors is coupled to a respective battery module in the set of N battery modules and measures a battery parameter of the respective battery module. The controller determines a preprogrammed delay for each battery monitor and provides the respective preprogrammed delay to each battery monitory. The controller transmits a synchronization command to the set of N battery monitors, which wait the respective preprogrammed delays in response to receiving the synchronization command before stopping updates to values of the respective battery parameters. The controller transmits a read command to the set of N battery monitors, which transmit read responses to the controller comprising values of the battery parameters.

Abstract: A method includes receiving, by a first device in a stack, a command from a controller. The stack includes multiple devices. The method also includes dissipating, by the first device, an amount of power responsive to a difference between a longest response time for the devices to respond to the command, and a device response time for the first device to respond to the command.

Abstract: A monitor circuit for use in a management system with modular subsystems includes: a sensor configured to measure parameter values of a monitored electrical component as a function of time; and storage coupled to the sensor and configured to store the parameter values. The monitor circuit also includes frame preparation circuitry coupled to the storage and configured to prepare frames that include the parameter values, wherein the prepared frames vary in length as a function of time.
