The undervoltage protection function of electric vehicles is a protective mechanism implemented to prevent excessive battery discharge while driving the electric vehicle. So, what should I do if the lithium battery cannot be charged after undervoltage?
1. If the lithium battery cannot be charged after undervoltage, the car owner can choose the fast charging method, directly use a high-power charger to charge, or directly go to a fast charging station to store the lithium battery. battery. Lithium battery. Once it is fully charged, use a multimeter to measure the voltage of the lithium battery to see if the voltage has recovered.
2. You can also use lithium batteries of the same specification and use wires to connect two lithium batteries in parallel for repair. However, vYou need to connect the positive and negative poles when wiring and use the new lithium. Battery to replace the old battery. Discharging can restore voltage. After discharging for a period of time, you can use a multimeter to measure and check whether the voltage of the old battery has been successfully restored.
3. Or use a charger with lower power than the original one. Typically, charging takes about half an hour. Using the original charger can effectively restore the battery.
Can be corrected.
1. Open the lid and you can see that it is made up of many small batteries connected in series and parallel.
2. First check if there is a disconnection point. If connected, check the protection circuit first.
3. If there is no problem with the protection circuit, we need to solder the battery and use a multimeter to check the chbattery groin, which can be done quickly.
