Product Description

18650/21700 Battery Bms 10S 40A 42V Bms Lifepo4 Batterie 18650 Lithium-Ion Battery With NTC For RV Car 

Product Description

Main functions of the individual PINs that protect the IC:

  • VDD is the positive power supply of the protection IC
  • VSS is the negative power supply of the protection IC
  • V- is the overcurrent and short circuit detection terminal of the protection IC
  • Dout is the discharge protection terminal
  • Cout is the charging protection terminal
  • Working process of protective board

B+ and B- are connected to the positive and negative poles of the battery cells respectively. P+ and P- are the positive and negative poles of the protection board output respectively.

T is the NTC port for temperature detection.The NTC port needs to cooperate with the MCU to protect the battery temperature. This port is sometimes marked as ID, which is used for battery port identification.

 

The reason why this port is added is because batteries of different manufacturers and different models often require different battery parameters (aging curves and other parameters).

When it is ID, R3 generally It is the resistance of the fixed resistor. The ADC of the MCU will detect the voltage of the ID and use different battery parameters.

18650 / 21700 Battery BMS 10S 40A 42V Lifepo4 Lithium Ion Battery For RV Car 6

This protection board supports 8S-10S
Different string number selections can be achieved by changing part A.
8S: Connect the "8S" position with a 1K resistor;
The "10S" position is left blank.
9S: Leave the "8S" position blank;
The "10S" position is left blank.
10S: Connect the "10S" position with a 1K resistor;
The "8S" position is left blank.

 

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!
