What is the lithium battery protection board port?

The lithium battery protection board is to protect the lithium battery, and it is connected by many ports. What ports does it have? What is the lithium battery protection board port? Let’s study with everyone today. The specific analysis is as follows:

VDD is the positive pole of the IC power supply, VSS is the negative pole of the power supply, V- is the overcurrent/short circuit detection terminal, Dout is the discharge protection execution terminal, and Cout is the charge protection execution terminal. 2, protection board Port description: B+, B- are the positive and negative of the battery cell respectively; P+, P- are the positive and negative of the output of the protection board respectively; T is the temperature resistance (NTC) port, which generally needs to cooperate with the MCU of the consumer to produce a protection action As we will introduce later, this port is sometimes marked as ID, which means identification port. At this time, R3 is generally a fixed resistance resistor, allowing the CPU of the appliance to identify whether it is a specified battery.

1. Output negative electrode, charging negative electrode, battery negative electrode, must be wired in order, do not reverse the wiring to avoid burning circuit components

2, charging wire, discharging wire, battery negative electrode. Use thick wires as much as possible, otherwise large currents will not pass, and over-current protection will be achieved and the circuit will not work.

3. The positive output of the battery does not need to pass through the protection circuit and is directly connected to the output
