BMS (BMS Overview)
Lithium battery intelligent protection board is a management system tailored for large capacity series lithium battery pack, with voltage acquisition, high current active balancing, overcharge over pass temperature protection, coulombmeter, Bluetooth communication, host computer monitoring and other functions. Can be applied to lithium iron phosphate, ternary lithium battery type.
The protection board relies on the energy transfer active balancing technology with independent intellectual property rights, which can achieve A maximum continuous 2A balance current. The high current active equalization technology can ensure the consistency of the battery to the greatest extent, improve the battery range and delay the aging of the battery
The protection board has a mobile APP supporting Android and IOS operating systems. The APP can be connected to the protection board through the Bluetooth of the mobile phone to check the working status of the battery, modify the working parameters of the protection board, control the charge and discharge switch, and so on. The protection board has small size, simple operation and full functions, and can be widely used in the battery PACK of high-power energy storage, base station backup power supply, solar power station and other products.

Active equalization
The protection board adopts active equalization technology, and the principle of equalization is to transfer the energy of the high-voltage cell to the low-voltage cell, and realize the energy transfer through the medium of the protection board. Before using the balancing function, users need to set the basic parameters of the battery and download the JIKONG BMS-APP. After downloading, set the battery type on the parameter setting page of the extreme space APP. After setting the battery type, set basic battery parameters in common Settings, including the number of cells, battery capacity, trigger equalization differential pressure(the default value can be retained), voltage calibration, and current calibration.
Users can set the balance trigger pressure difference (mV) in the parameter setting of the APP. When the balance is turned on, the balance will be turned on automatically when the pressure difference of any two strings of batteries in the battery pack is greater than the set value, and the balance will be turned off when the pressure difference is less than the set value. The default balance current is 1A/2A. Users can adjust the balance current

according to their own battery capacity. It is recommended that the balance current not exceed 0.2Cof the battery capacity (C). If you do not need the balancing function, you can set the balancing switch to off in the BMS control

page of the APP.

Display interface
The display interface is reserved for the protection board, which supports users to select our display for convenient viewing of battery information. Users can select and select according to actual needs.

Heating function
The protection plate comes standard with heating function. The resistance heater or heating film is used to heat

the battery at low temperature to avoid the failure of charging and discharging due to the decrease of battery activity caused by low temperature. The designed heating current is 10A. This function allows users to switch operations in the BMS control page of the APP according to their actual temperature. At the same time, it is recommended to series a temperature control switch in the heating circuit as a secondary protection to prevent thermal runaway in extreme cases. You are advised to select a normally closed temperature switch of 45 °C to 65 °C. When the temperature reaches the threshold of the temperature switch, the temperature switch is turned off and the heating circuit is cut off to prevent further heating.

Dry contact function
The protection board is equipped with two dry contacts to control external devices such as alarms and fans. When the BMS detects that the battery is in overtemperature, overcharge, or over discharge state, the alarm interface can switch the status of the dry contact to drive the buzzer to alarm or drive the fan to cool down. You can select two trigger conditions based on your requirements. After switching the trigger alarm conditions, users need to set the conditions according to their own needs.
