Lithium battery has been widely used in mobile devices represented by smart phones. However, in recent years, the rising tide of “green and environmentally friendly electrification” also makes ordinary people more interested in EV battery management system. When the cell phone battery is seriously degraded, users usually want to upgrade the next generation of devices. But for the power batteries on electric vehicles, manufacturers still want to make them as long as the whole vehicle. < / P > < p > the technology, created by analog devices, Inc., will be the first to become standard on GM’s EV Models. The company aims to achieve at least one million global sales within a decade. < / P > < p > it is worth mentioning that these models will be equipped with GM’s proprietary ultium power battery, which comes from a 2.3 billion new plant invested by LG Chemical in Ohio. < / P > < p > unlike the battery management system currently connected to the vehicle management system through tangled orange wires, Ge directly integrates RF RF antenna on the circuit board, allowing data transmission via a 2.4GHz wireless protocol similar to Bluetooth. < / P > < p > the battery module can report the measured values of battery voltage and other data to the main management system wirelessly, and support the connection with the cloud system of general motors company, so as to realize more comprehensive operation condition monitoring, including extreme conditions and real-time driving data. According to Fiona Meyer Teruel, chief engineer of GM’s battery electronics system, this means there is a central warehouse to monitor all of these devices. < / P > < p > in detail, the wireless battery management system supports the load and wear balance of each battery pack to achieve the best performance. When the battery performance drops below 70%, it can be easily recycled or replaced. < / P > < p > in addition, the system can be plug and play for all EV Models, including heavy trucks and performance models, without the need to redesign (wiring harness or communication system) for each electric vehicle.
