1. A method for functional safety in a battery management system, the method comprising:
generating, by a module monitoring system of the battery management system, battery sensor data;
generating, by the module monitoring system, based on the battery sensor data, integrity data;
sending, by the module monitoring system, via a wireless black communication channel to a wireless network controller of the battery management system, the battery sensor data and the integrity data; and
sending, by the wireless network controller, to a vehicle control system, the battery sensor data.
 
12. A battery management system comprising:
a plurality of module management systems each configured to monitor a corresponding battery module of a plurality of battery modules;
a wireless network controller; and
wherein the battery management system is configured to perform steps comprising:
generating, by a module monitoring system of the plurality of battery management systems, battery sensor data;
generating, by the module monitoring system, based on the battery sensor data, integrity data;
sending, by the module monitoring system, via a wireless black communication channel to a wireless network controller of the battery management system, the battery sensor data and the integrity data; and
sending, by the wireless network controller, to a vehicle control system, the battery sensor data.
