Introduction to the use of lithium battery protection board

The lithium battery protection board is suitable for charging and discharging protection of 10 lithium battery packs. When overflowing, it can ensure that the voltage difference between the individual cells is less than the set value (generally ±20mV), realize the equal charge of the individual cells of the battery pack, and effectively improve the charging effect in the series charging mode. At the same time, test the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single battery in the battery pack to protect and extend the battery life. Under-voltage protection makes each single cell battery be warned of damage due to over-discharge during discharge. The product can work stably and reliably for a long time in the ambient temperature range of -20℃~+60℃. Technical parameters: Equalization current: 80mA (VCELLu003d4.20V) Equalization starting point: 4.18±0.03V Lithium battery protection board schematic diagram Overcharge threshold: 4.25±0.05V (4.30+0.05V optional) Overcharge delay: 75mS overcharge release: 4.05±0.05V overdischarge threshold: 2.90±0.08V (2.4010.05V optional) overdischarge delay: 5mS overdischarge release: disconnect the load, and the voltage of each single battery is higher than the overdischarge threshold ; Over-current threshold: 30A (according to customer choice) Over-current release: disconnect load release Over-temperature protection: interface, need to install a recoverable temperature protection switch; working current: 15A (according to customer choice) static power consumption: <0.5 mA short-circuit protection function: can protect, disconnect the load can be self-recovery. Important functions: overcharge protection function, over discharge protection function, short circuit protection function, over current protection function, over temperature protection function, balance protection function. Interface meaning: the charging port and the discharging port of the board are independent of each other, they share the positive pole, B- is the negative pole of the battery, C- is the negative pole of the charging port; P- is the negative pole of the discharge port; B-, P-, C -The pads are all through-hole type, and the diameter of the pad hole is 3mm; each battery charging test interface is output in the form of a DC pin socket.
