Wireless BMS: Perils and Possibilities for Electric Vehicles (Download)
A battery-management system (BMS) is one of the key components of electric vehicles. It’s crucial for ensuring safety, longevity, and managing the performance of battery packs. The BMS controls the state of health and state of charge of the battery cells, thus optimizing their stability through cell balancing. It oversees such core parameters as cell voltage, current, and temperature to make sure everything is within safe limits.
Today, most automotive manufacturers are trying to decrease the resource intensity of their designs. While wired BMS has proven reliable over time, it heavily relies on copper wiring and electrical connectors, which can wear out over time. Locating and repairing these issues is usually very costly.
