The EV battery management system consists of 3 parts: Battery Management control Unit (BMU), High voltage Management control Unit(HMU) and Local Electrical Control Unit(LECU). Together, they make the BMS report real-time data and diagnostics to protect the battery and prevent premature failures, reducing service and warranty costs.
1. Completely solve the safety problems in use of lithium battery
The battery management system has extensive fault detection and protection capability: overcharge, overdischarge, over current, high temperature, short-circuit, reverse polarity, charge and discharge device fault, management system self- fault, wiring or connector malfunctions, illegal operations, and so on. Reliable and striking screen, warning and automatic multiple measures of protection makes user at ease.
2.Accurate electric parameter measurement improves the use of battery capacity
Based on the accurate measurement of electromotive force in the use of battery, synthetically monitor temperature and other parameters, estimate the remaining capacity of the battery pack, and error control in 5%.
Battery total voltage detection precision: precision of 1%
Battery voltage detection precision: precision of 3mV
Current detection precision: precision of 0.5A
In order to make it easier for users, BMS ensure the above functions at the same time, simplify external output interfaces. The external connections only includes power cord, battery sampling lines and communication lines with clear and simple operability.
BMS has a built-in power converter, sensor interfaces, you do not need additional function units, when a single module capacity is insufficient, you can implement multiple modules by cascading expansion. Waterproof, dustproof and shockproof design, from direct sales components selection and chip manufacturers research, sample test, high temperature aging cycle, circuit board testing, product inspection, testing and other aspects of strict control and records, ensures product quality and professional maintenance team.
5.Improve the mileage and cycle life of battery pack
High-tech power equalization fully guarantee the consistency of the battery pack. Based on charging of battery performance, intelligent charger matching can be adjusted by real time strategy and have a certain restoration effect on the battery which extending the battery life.
