The intelligent protection board of lithium battery is a management system tailored for large capacity series lithium battery pack. It has the functions of voltage acquisition, active current equalization, overcharge, over discharge and over temperature protection, coulometer, Bluetooth communication, GPS remote control, etc. It can be applied to lithium iron phosphate, lithium ternary batteries and other types.
Based on the energy transfer active equalization technology with independent intellectual property rights, the protection board can achieve a maximum continuous current of 2A. The high current active equalization technology can ensure the battery consistency to the greatest extent, improve the battery range and delay the aging of the battery.
The protection board has a supporting mobile app, supporting Android and IOS operating systems. App can be connected to the protection board through Bluetooth to view the battery working status, modify the working parameters of the protection board, control the charge and discharge switch, etc. Due to its small size, simple operation and complete functions, the protection panel can be widely used in battery pack of small sightseeing car, scooter, shared car, high-power energy storage, base station standby power supply, solar power station and other products.
