Analysis of treatment and maintenance methods for over-discharge of lithium iron phosphate battery pack

The iron-lithium discharge curve is very straight. It is impossible to judge the electric quantity by voltage alone. The equalization can only be balanced by the cell filling up. The discharge after filling up is not balanced, that is, the cell internal resistance and capacity are inconsistent. There is no other way to deal with it by changing the content. First connect a resistor in series and charge it straight from the battery for half an hour, and then the protection board opens. Then charge it from the charging port of the protection board, or if you want to charge it from the discharge port for half an hour, it can be charged normally. You need to charge from the discharge port. Pay attention not to reverse the polarity. If the red light is on, it will do. You can also use another set of battery packs to charge him, 36/48 will do, the resistance is 50 ohms, 100 ohms and 200 ohms. The battery can be charged normally after charging the battery to 30v or more. The hand will be hot when the resistor is close heat. If it still doesn't work, consider replacing it. In fact, don't wait until the battery has a problem, and then think about how to deal with it. It is important to pay attention to the maintenance of the battery on weekdays. Battery maintenance methods: 1. Fully overcharged each time to reduce the number of recharges and improve battery life. 2. There is no need to completely discharge the battery. Usually the battery will be charged if the battery is less than 10%. 3. Don't use it while the phone is charging. 4. Don't overcharge, stop charging continuously after the battery overflows.
