With the increasingly serious energy shortage and environmental pollution, the development and utilization of new energy has been paid more and more attention by governments. Among them, lithium battery in power battery system has attracted more and more attention due to its advantages of high energy density, high number of repeated use, light weight and green environmental protection. So what is battery management system? In addition, what are the advantages of new energy vehicles for battery management?
At present, new energy companies with independent intellectual property rights of battery management system related products in China include 'super thinking', 'Kelei', 'Ligao' and 'Zhongyuan Electronics'.
Battery management system is the link between battery pack and vehicle system, which can provide safe, efficient and reliable management for vehicle power battery and protect the safe operation of battery. The traditional battery management system mostly uses single chip microcomputer as the core controller, which makes the system difficult to meet the requirements of real-time data acquisition, stability and reliability. With the rapid development of computer technology, especially embedded technology, DSP with strong processing ability is widely used in battery management system. Therefore, most manufacturers begin to use DSP or FPGA as the core controller to study the battery management system.
The general battery management system is divided into main control BCU and slave control BMU. Through the cooperation of BCU and BMU, the functions of data acquisition and data transmission can be completed.
