BMS informations

 Our BMS consists of Master BMS Circuitry (we named “BMU”), Slave BMS Circuitry (we integrate it into our
battery module) and contactor. Besides the basic functions such as over charge/ discharge,over current, short
circuit, over temperature and balancing, Our BMS owns the following features, 
1. Master-Slave architecture makes the system flexible;
2. Two level warning makes maintenance easier;
3. CAN2.0 and industrial level electronic components make system reliable;
4. Contactor makes high rate charge & discharge feasible;
5. Periodic insulation measurement makes personnel safety possible;
6. Host can control the system easily;


1.   High energy density

2.   High working voltage for single battery cells

3.   Pollution-free, environment friendly

4.   Long cycle life; It extends its cycle life up to 800 cycles

5.   Capacity, resistance, Voltage, platform time consistency is good

6.   Simplifying battery management system (BMS) and a battery charger

4. We could design and produce the battery pack with aluminum alloy shell and assembly procession for customized configurations is available (we could design and develop Li-ion battery according to your product work performance & structure appearance)

5. Bulk pack is available

Lithium ion batteries are common in consumer electronics. They are one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. In addition to uses for consumer electronics, lithium-ion batteries are growing in popularity for defense, automotive, and aerospace applications due to their high energy density. Li-ion batteries are lighter than other equivalent secondary batteries—often much lighter. The energy is stored in these batteries through the movement of lithium ions.

A key advantage of using Li-ion chemistry is the high open circuit voltage that can be obtained in comparison to aqueous batteries (such as lead acid, nickel metal hydride and nickel cadmium).
