18650 lithium ion battery 3.7v

Analysis of the use method and technical parameters of the 18650 lithium ion battery 3.7v protection board tester

The 18650 lithium ion battery 3.7v protection board tester is developed based on the current 18650 lithium ion battery 3.7v protection board production process, using the principle of capacitor simulation battery charging and discharging. It has the characteristics of complete functions, simple operation, and fast detection speed. The 18650 lithium ion battery 3.7v protection board tester is mainly used to test battery parameters and battery protection time. The use method of the 18650 lithium ion battery 3.7v protection board tester is for different 18650 lithium ion battery 3.7v protection boards. The fastest test speed can reach 0.5 seconds/piece, which greatly improves the test speed. It is particularly suitable for factory mass production factory inspection. The test speed only depends on the overcharge delay time and over-discharge delay time of the tested protection board. The test starts automatically when the protection board is connected. No key operation is required, which reduces the complexity of the worker's operation and can greatly improve production efficiency. Fast testing can determine the function of a protection board in a very short time. Accurate testing can obtain accurate test data of the protection board in a very short 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 parameter is accurate to 1mΩ. The delay time test can test the overvoltage protection delay, over-discharge protection delay, and over-current protection delay of the protection board. Each time parameter is accurate to 1mS, providing the most accurate setting parameters for accurate test data, thereby obtaining the fastest test speed and the highest accuracy. The code reading test can test and read the code data test content and accuracy index of the MOTOLORA mobile phone protection board. Main technical parameters of 18650 lithium ion battery 3.7v 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 protection speed is measured to be above 200mS, it means that the board has no short circuit protection. 6.
