Analysis of the reasons and solutions for the non-discharge of lithium-ion battery packs

Analysis of the reasons why the lithium-ion battery pack does not discharge: 1. Check whether the battery/battery pack is a zero-voltage, high internal resistance battery; 2. Whether the electronic components and the protection circuit are damaged in the battery pack; 3. Check whether the discharge circuit of the device is normal; 4. Whether the tabs are broken, forming an open circuit and the lithium-ion battery pack does not discharge. The solution: 1. Use a fully charged battery/battery pack of the same type to connect to the device, and whether the device is working properly; 2. Use a multimeter to test the internal electronic components , Whether the protection circuit is normal; 3. Repeat the analysis and treatment of the zero voltage step of the single battery; 4. If the discharge circuit of the electrical appliance is abnormal, it is recommended that the customer repair and replace the electrical appliance in time; 5. If the customer does not modify the battery pack by himself, then Special technical personnel are required for further analysis.
