Description

Enerkey 4S Lithium Battery Pack BMS Board Lifepo4 Protection Board 18650 BMS For E-bike

Product Description

BMS is the abbreviation of Battery Management System. It is a battery management device mainly used to monitor, protect and manage the the battery system.It helps improve the safety and effectiveness of the battery by regulating multiple factors such as voltage, current temperature and state of charge.

The BMS is made up of many components (sensor, control circuit, microcontroller, communication interface) that work together to control the battery's performance.

(1) Microcontroller
The central processing unit of BMS. It collects data from numerous sensors, and then the internal control program uses this data to operate the battery.

(2) Sensors
Sensors monitor most characteristics of the battery, including voltage, current, temperature, and state of charge.

(3) Switches
Battery switches are used to cut all power from a battery bank and connected loads. They can be used in an malfunctioning or emergency shut down.

(4) Cell Balancer
A cell balancer helps to balance charge and discharge of each battery cell which can extend the battery life span and keep battery in a health state.

(5) Communication Interface (not all BMS have)
BMS can communicate with other devices through communication interfaces, including the car's on-board computer. This interface can provide important diagnostic data about battery status and functionality.

Wire Diagram

Enerkey 18650 4S Lithium Battery Pack BMS Board Lifepo4 Protection Board For E-bike

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!
