Function and Usage of Lithium Battery Comprehensive Tester

Lithium battery comprehensive tester is a device for quick testing lithium battery packs with protective BMS board.

1、 Function of lithium battery comprehensive tester

It is a fast and accurate equipment for testing the performance of finished batteries. The main test items include: open circuit voltage, AC internal resistance, discharge test, discharge overcurrent test, short circuit protection test, charge test, charge protection test, self discharge rate, cycle life, safety performance, overcharge and overdischarge, etc.

2. How to use the battery comprehensive tester?

1. Power switch: tester’s power switch;

2. Emergency stop switch: cut off the battery discharge circuit and charging circuit in case of emergency;

3. When the computer is turned on, press this button for about 1s, the screen will light up automatically, and then short press the computer’s off button.

4. On the home page of the lithium battery comprehensive tester test software, select the lower computer trigger, and press this button to trigger the system automatic test. When the computer is running normally, sudden power failure or forced shutdown may cause damage to computer files. It is recommended to cut off the power again when the computer is turned off. If the software fails to start normally, you can delete the original program, decompress the backup program file and continue to use it.

3、 Introduction to clamp wire clamping method:

1. P+: battery positive terminal;

2. P -: battery negative terminal;

3. C+: Heterogeneous charging positive terminal;

4. C -: Heterogeneous charging negative terminal.

The charging and discharging terminals are the same. Generally speaking, the battery has only one positive pole and one negative pole. The charging and discharging are not at the same port. There are three types of batteries with different ports: positive, negative, and both positive and negative electrodes.

1. Positive different ports: the negative pole is the same port, and the charging positive pole is not the same port as the discharging positive pole;

2. Negative pole is different: the positive pole is the same port, and the charging negative pole is not the same port as the discharging negative pole;

3. Anomaly between positive and negative electrodes: the battery has two groups of positive and negative electrodes, and the charging and discharging ports are not shared.

The lithium battery comprehensive tester is one of the lithium battery testing equipment belonging to the lithium battery assembly equipment. This process of the lithium battery comprehensive tester is the last step, that is, whether the entire lithium battery pack can be used and safe after welding. If it is qualified, it is a well-finished product and can be sold.

Another thing to remind is that the lithium battery comprehensive tester can only be used after the protection board is installed on the entire battery pack, because the protection board has two wires, one positive and one negative, and the comprehensive tester has two clamps to clamp for detection.
