background The Battery Management System (BMS), commonly referred to as the “brain†of new energy vehicle batteries, is combined with the power battery pack and the vehicle control system to form the three core technologies of new energy vehicles. The high energy density characteristics of the power lithium-ion battery make it the main power source for new energy vehicles. However, due to the difference in production process and use environment, the inconsistency of the battery pack gradually expands during use, and overcharge and overdischarge may occur. The danger of local overheating seriously affects the service life and safety of the battery pack. As a protective power lithium-ion battery, BMS uses a safe control system to monitor the battery usage status at all times, and to alleviate the inconsistency of the battery pack through necessary measures to ensure the safety of new energy vehicles. As a high-quality power system supplier in China, Hengrun Technology has strong strength and rich experience in control systems, and can provide customers with high-quality engineering and supporting services in battery management system development.
