A management system designed specifically for large-capacity series lithium battery packs is the lithium battery intelligent protection board.
Backup voltage collection, big current active equalization, overcharge, over-discharge, and overtemperature protection are among the features. There are also coulomb counters, Bluetooth communication letters, GPS remote controls, and other features. applicable to ternary lithium, lithium iron phosphate, and other battery types.
The protection board can achieve this by relying on energy transfer active equalization technology with independent intellectual property rights.
2A is the maximum continuous equalization current. Using large current active equalization technology can guarantee consistent maximum power, increase battery life, and slow down battery aging.
A mobile APP that supports both Android and iOS is available for the protection board. With an APP, you may connect to the protection board through Bluetooth on your phone to monitor the battery’s operational state, change the protection board’s operational parameters, manage the charge and discharge switch, and more. The protection board is compact, user-friendly, and functional. It is frequently used in battery packs for scooters, shared cars, tiny sightseeing cars, solar power stations, high-power energy storage, and base station backup power.
