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
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
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
