NiMH No.7 battery.Introduction to the usage and technical parameters of lithium battery protection board tester

　　Introduction to the usage and technical parameters of the lithium battery protection board tester. The lithium battery protection board tester is developed based on the current lithium battery protection board production process and uses the principle of capacitance to simulate battery charging and discharging. It has the characteristics of complete functions, simple operation and fast detection speed. The lithium battery protection board tester is mainly used to test battery parameters and battery protection time.

　　How to use lithium battery protection board tester

　　For different lithium battery protection boards, the fastest test speed can reach 0.5 seconds per piece, which greatly improves the test speed. It is especially suitable for factory inspection of mass production in factories. The test speed only depends on the protection board being tested. The overcharge delay time and over-discharge delay time are set, and the test will start automatically when the protection board is connected. No button operation is required, which reduces the complexity of the worker's operation and can greatly improve production efficiency.

　　Quick testing can determine the function of a protective board in a very short time.

　　Accurate testing can obtain various accurate test data of the protection board in a short period of time. The voltage parameters are accurate to 1mV, the self-consumption power is accurate to 0.1uA, the overcurrent value is accurate to 0.01A, and the internal resistance parameters are accurate. to 1mΩ.

　　Delay time test can test the over-voltage protection delay, over-discharge protection delay, and over-current protection delay time of the over-protection board. Each time parameter is accurate to 1mS, providing the most accurate setting parameters for accurate test data. This results in the fastest testing speed and highest accuracy.

　　Code reading test can test and read the chip data test content and accuracy index of the MOTOLORA mobile phone protection board.

　　Main technical parameters of lithium battery protection board tester

　　1. Input power: AC220V±10%50Hz±2Hz

　　2. Rated power: 15VA

　　3. Overcharge voltage: 0-5.0V

　　4. Over-discharge voltage: 1.5-5.0V

　　5. Leakage current: 0-199.9uA Short-circuit protection speed: 0-200mS. Generally, the short-circuit protection speed is within 10mS. If the measured protection speed is above 200mS, it means that the board does not have short-circuit protection.

　　6. Voltage test accuracy +1.5%
