Enerkey Normal BMS 3S 12V 80A Lithium Battery PCB with Passive Balance Two NTC MOS For Li-ion/LiFePo4/lto
Product Description
Battery management systems (BMS) are becoming increasingly complex as EV technology develops. It is expected that the future BMS will include cutting-edge capabilities like predictive analytics for greater performance optimization, increased safety protocols,
and improved integration with other vehicle systems. Using historical data and machine learning algorithms, predictive analytics make predictions about the future.
This can entail projecting past performance to forecast the battery’s future state-of-charge (SOC) or overall health,
in the context of a BMS. This would make it possible to manage the battery more proactively, thereby extending its lifespan and enhancing the efficiency of the EV.
Improved safety standards might include more sophisticated techniques for anticipating and avoiding potential battery issues.
This might require more complex algorithms for spotting irregularities that might point to a possible issue as well as more comprehensive monitoring of the battery's condition.
The BMS could communicate more directly with other EV systems, such as the motor controller or the onboard computer, to improve integration with other vehicle systems.
This may make it possible for the car to operate more smoothly, which will enhance its effectiveness, performance, and user experience.

Wire Diagram
Wiring precautions:
1. Installing the protective board requires a certain amount of
technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad
position to the total negative terminal of the battery (the B- wire
should be soldered to a short and thick wire) and solder the wired
terminal to the battery pack first, and then insert the protective
plate.
3. The connection between the battery terminal B- and the
protection board terminal B- should be short and thick, otherwise
it will cause the protection board to charge and discharge in
advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
