Wireless BMS helps upgrade new energy vehicles

In the first half of 2022, the sales of new energy vehicles in the global market took off, and the sales of new energy vehicles in Chinese Mainland in the first half of 2022 were particularly prominent, creating an astonishing growth of more than 100% year on year. When new energy vehicles start to enter thousands of households, people have increasingly high requirements for battery systems, both to improve the endurance and ensure safety and stability. As a result, a major innovation technology in the industry is ready to emerge, that is, wBMS, wireless battery management system.

Advantages of Wireless BMS

The cost of BMS accounts for about 20% of the power battery of new energy vehicles. The traditional BMS connects the battery pack through the cable, and then uses the chrysanthemum head to bridge. The use of cable and mechanical structure interface leads to large space occupation and counterweight increment, which actually squeezes the space for improving the battery energy density. The wireless BMS changes the traditional serial loop circuit, deploys wireless communication modules on the BMS host and battery pack nodes, and realizes the star+ad hoc network mode to achieve the communication necessary for battery management. The wireless mode not only improves the space for improving energy density, but also greatly reduces the manual input in the battery assembly stage. In addition, the wireless solution does not need to provide high and low voltage isolation by means of high cost
