BMS 20S 60V lifepo4 72V литиевая 60-100A плата защиты батареи с балансом для скутера Ebike Солнечная энергия UPS батарея питания

BMS Parameter:

It is suitable for quick and balanced charging and over voltage, under voltage, over current, short circuit and over temperature protection of single battery in series power battery.

When fully charged, the voltage difference between the individual cells can be guaranteed to be less than the set value (generally ±20mV), so as to realize the realization of the battery pack of each single cell

The uniform charging can effectively improve the charging effect in series charging mode.At the same time, the overvoltage, undervoltage,

Over current, short circuit, over temperature condition, protect and prolong battery life.Undervoltage protection protects each single cell from electricity during discharge use

The pool was damaged by over discharge.This series of products can work stably and reliably in the range of -20℃ ~ +60℃ ambient temperature.

Installation mode of protection board: the balanced protection board is installed in the battery pack.The charger is externally connected, the positive electrode is connected to the battery pack, and the negative electrode is connected to the battery pack

C-terminal connection on the guard plate;Connect with the battery pack through the output line (plus or minus two lines);

Equalization starting point: 3.53 ±2 0.02V V

Overcharge threshold: 3.90 ±5 0.05V V 0 (4.20 4.30 ±5 0.05V V optional)

Overcharge delay: 1 1 ± 0.5s

Overcharge release: 3.80 ±5 0.05V V

Over discharge threshold: 2.10 ±5 0.05V V 0 (2.80 2.40 ±5 0.05V V optional)

Over delay: 100 ± 50mS

Overdischarge: disconnect the load, and the voltage of each single cell is higher than the overdischarge threshold;

Over current threshold: 30A (according to customer selection)

Overcurrent release: Disconnect load release

Overtemperature protection: with interface, it is necessary to install restorable temperature protection switch;

Working current: 15A (according to customer's choice)

Static power consumption: < 0.5mA

Short circuit protection function: can protect, disconnect the load can self-recovery.
