About BMS
    We can also provide the BMS(BMS=Battery Management Syestem) if you need.

Li-ion BMS Introduction
when batteries are charging, it can open the balance function to balance the voltage of a battery with a high voltage and can make each of all batteries to get a balance in the maximum extent.
Our BMS(Battery Management System) consists of some modules. Each module can control 5 to 13 units of battery. All of them will get coordination from a host computer, so as to control and manage the whole batteries.

System Function Brief:
1. Capable of monitoring the voltage of each battery, the voltage of battery module and the voltage of the whole batteries in the same time.
2. Capable of monitoring the battery charge and discharge current, and has a protection of short-circuit and overloading.
3. It can automatically identify and monitor the voltage of one battery in charging and discharging, and can measure the internal temperature of an entire battereis, and it can prevent a battery from overcharging, over-discharging, overloading, short-current, overheating.
4. When batteries are charging, it can open the balance function to balance the voltage of a battery with a high voltage and can make each of all batteries to get a balance in the maximum extent.
5. You can choose standard BUS connector such as RS485, CAN
6. It can be expanded to manage any of the dozens or hundreds and even more of batteries.

According to your company's technical requirements, we will adopt the following resolution:
1. to select contactors used as switches;
2. to use high-precision current sensors acting as acquisition devices of current signal;
3. the cooling system consists of radiators and fans;
4. to select imported chips to achieve the good reliability and stability;
5. the most optimized design will bring up good anti-interference and perfect security.
