Abstract:
A vehicle can include a battery architecture configured to provide electrical power to motors, accessories, and other components of the vehicle. The architecture can include a controller coupled to multiple battery units. Each battery unit can include a battery and a battery management system. Additionally, each battery unit can be coupled to a controller and to other battery units. Through the use of redundant coupling and redundant data transmitted to and from the controller, battery units, and other components, the architecture can detect a fault and continue to operate while providing an indication of the fault.
