Currently we are using EV STANDARD BMS for the battery,it is MCU,relays,pre-charge resistors,hall sensors….Even with CAN BUS communication protocols. Management is more efficient, effectively prolonging the service life of lithium battery.
Lithium battery is like a living body, and its state changes all the time. This change is affected by multiple factors. It is difficult to find a “perfect” mathematical model to represent all its changing characteristics once and for all. In addition, traditional BMS can only calibrate model parameters based on the limited battery sample data in the laboratory before leaving the factory. Once the BMS leaves the factory, these models and parameters will be fixed and cannot accurately match the state changes in the whole process of battery application. The management efficiency can be imagined.
Our BMS smart terminals are highly integrated with wireless data transmission units. Based on 4G or 5G mobile networks, they can achieve large concurrency, high reliability, two-way real-time wireless interconnection with battery PaaS cloud platforms, and combine big data technology and artificial intelligence algorithms in the cloud. It supports the dynamic optimization of battery models and parameters. Through its unique cloud collaborative management technology, it finally realizes data-driven online management of the entire life cycle of lithium batteries, effectively improving battery management efficiency, extending battery life, and maximizing battery efficiency.
At present, a number of advanced cloud collaborative management technologies have been developed and applied on a large scale: cloud full-time equalization technology to increase vehicle life by 10%; cloud auxiliary power control technology to extend battery life by 15%; cloud SOC correction technology to reduce errors Up to 3%.
