If electric vehicles and hybrids are to reach their full potential, battery management must improve. That generally means successfully managing the state of health and state of charge of hundreds of individual cells. Thorough and accurate monitoring of all those cells has long implied additional wiring, which can add to a vehicle’s complexity and weight, as well as potentially add failure points. A solution that’s gained traction recently is wireless monitoring (e.g., through short-range RF such as Bluetooth).
A wireless approach offers simplicity and potentially better monitoring, but it also comes with complexities that need to be addressed.
