On September 10th, General Motors will be the first in the industry to realize the application of wireless battery management systems in mass-produced electric vehicles. This technology jointly developed with Analog Devices, Inc is almost entirely based on wireless and will support GM to build a rich lineup of electric vehicles with 'universal' battery components. The wireless battery management system will balance the chemical performance of each cell to optimize the overall performance of the battery. It can also monitor the health of the battery pack in real time, and then adjust the modules and sensors to ensure the health of the battery during the life cycle of the vehicle. The battery using the wireless battery management system reduces the wiring harness by 90%. This reduces the quality of the entire vehicle, creates space for carrying more batteries, and is conducive to improving the cruising range. At the same time, the design of the battery pack is simpler, the structure adjustment is more convenient, and the manufacturing process is more stable.
