The pulse charger is a device that can be used to charge and maintain batteries. It can attempt to restore battery performance and capacity through a series of pulse charge and discharge operations when the battery voltage is below a certain level. Therefore, the pulse charger can be used to repair electric vehicle lithium batteries, but its effect is not 100%.
Regarding power depletion activation, some pulse charger manufacturers advertise that their devices can activate a depleted battery via pulse charging. This means that the battery has entered protection mode because it has not been charged. for a long time, the battery voltage drops. Through the operation of the pulse charger, the battery can be “wake up” and returned to normal operating condition. However, hejust noted that pulse chargers cannot solve all battery problems. Significant aging and damage may require replacement of new batteries.
1. Use an electric vehicle battery charger to repair the battery:
The charging voltage and current of the electric vehicle charger match the model and specifications of the electric vehicle battery. . Therefore, the battery cannot be repaired with a car charger. You must use a higher wattage electric vehicle charger. Example: 1. The electric vehicle battery specification is 48v20AH, which can be charged and repaired with 60V20AH battery charger; 2. The 48v12AH battery, which can be charged and repaired with a 48v20AH battery charger.
Repair principle: The main reason for the decline in battery performance is that the battery has been seenlcanized. After-sales battery maintenance by battery manufacturers, various battery repair instruments and restorers on the market all use high-quality materials. electric charging equipment, using "high current, high voltage" to remove sulfide and repair batteries. Therefore, an ordinary charger with higher power can charge the battery with sulfur removal and repair function.
2. Other methods:
Use hot water from a dry cleaner to repair the battery
The majority of electric vehicle users realize that electric vehicles cannot travel long distances. . Add distilled water to maintain and repair the battery. However, pure water and various replenishment fluids and repair fluids sold on the market have a short-term effect on the battery, and then accelerate the decline ofbattery performance and are discarded in advance. Because the metal ions and impurities contained in these liquids corrode the battery plates, cause the battery to self-discharge and the active materials to fall off, resulting in the permanent disposal of the battery.

Lithium electric vehicle charging instructions
1. Place it to recharge:
The battery has some remaining power before leaving the factory, and it can also be driven short distances after the electric vehicle is sold. After the first trip, the battery must be charged for the first time. It is recommended to carry out the first charge for a longer duration (8 to 12 hours).
The battery should be charged in time after use and should not be stored at a loss. If the battery has not been used for more thantwo months, the battery must be fully charged. If the battery is left for more than 5 months, it must undergo a charge and discharge cycle.
Use the battery regularly, use it normally and for a long timeRegularly charging the battery when left for a long time can ensure the best practical effect of the battery and prolong its service life.
2. Normal charging:
The normal battery charging method is as follows:
First connect the charger and the battery to be charged, then connect the power plug of the charger to 220V AC power supply. (This connection sequence will prevent sparking when plugging and unplugging the charging plug.) When the device is turned on, the charger displays a red light to indicate that the battery is charging normally. Charging may take 6-8 hours. .
3. Notes on the charger:
In order to ensure theBattery charging safety and ensure battery life, use a special charger. If the charger is lost or damaged, please purchase it from the corresponding dealer. Do not use lead chargers or other forms of chargers for charging.
