How do you fix an electric car battery for a lithium battery?

Electric car chargers (voltage, current, and battery types and specifications of electric cars are the same. Therefore, car chargers do not repair battery packs, but use larger electric chargers. Example: 1. The battery specification of electric vehicles is 48 v20ah. You can use 60 v20ah battery chargers for maintenance; 2,48 v12ah battery pack can use 48 v20ah battery charger for maintenance.

Maintenance principles: batteries are the main reason for the decline in performance sulfide. Battery manufacturers repair various batteries on the market during after-sale maintenance. Repair kits use high-power charging equipment, use high-current, high-pressure sulfide, and repair batteries. Therefore, a larger size ordinary charger charges the battery and, in addition to repairs, also has a sulfur function.

Other methods:

Repair batteries with dry cleaner hot water

Not far away users know the route of an electric bicycle, and you need to add distilled water to your maintenance battery. However, pure water and various supplements, supplements, and supplements sold on the market have a short effect on the battery, and then accelerate the decline in battery performance and waste is scrapped in advance. The impurities in these metal ions and liquids can be corroded, causing the battery to self-discharge and the active material to fall off, resulting in permanent battery waste.

Method One: Repair Battery Using Electric Vehicle Charger

Electric car chargers(voltage, current, and battery types and specifications of electric cars are the same. Therefore, car chargers do not repair battery packs, but use larger electric chargers. Example: 1. Electric vehicles are 48 v20ah battery specifications, 60 v20ah battery chargers can be used for maintenance; 2,48 v12ah battery pack, 48 v20ah battery charger can be used for maintenance.

Maintenance principles: batteries are the main reason for the decline in performance sulfide. Battery manufacturers repair various batteries on the market during after-sale maintenance. Repair kits use high-power charging equipment, use high-current, high-pressure sulfide, and repair batteries. Therefore, a larger size ordinary charger charges the battery and, in addition to repairs, also has a sulfur function.

Step: 1. Borrowing a is larger than repairing an electric charger for an electric car battery.

Charger, more powerful electric vehicles need to be charged for 4-6 hours to repair.

3, after charging, let the station restore the battery capacity for more than 90 %.

Method 2: Repair batteries using dry, clean, gaseous hot water

Not far away users know the route of an electric bicycle, and you need to add distilled water to your maintenance battery. However, pure water and various supplements, supplements, and supplements sold on the market have a short effect on the battery, and then accelerate the decline in battery performance and waste is scrapped in advance. The impurities in these metal ions and liquids can be corroded, causing the battery to self-discharge and the active material to fall off, resulting in permanent battery waste.

Battery dehydration is the reason for the failure of lead-acid batteries at the end of life. The use of three-stage chargers for charging electric vehicle batteries will cause dehydration for about half a year. The addition of a supplementary liquid(dilute sulfuric acid solution) increases the proportion of sulfuric acid in the electrolyte, although there is a short-term increase in battery capacity, accelerating the scrap of the battery after vulcanization. Therefore, the rehydration of electric vehicle batteries can only be added with pure distilled water, and no other liquids can be added.

Lithium batteries usually have at least 10 sets or multiple layers of lithium battery series, and battery protection panels are completely different from lead-acid batteries(fewer, generally without protective panels). In case of failure, non-professional technicians are generally unable to solve them.

Damage to lithium battery packaging generally includes the following:

1, battery protection plate damage, high electron density, general maintenance difficulties;

2, the battery protection plate is in good condition, the performance of a single battery is poor, it is not easy to find;

3, the battery protection plate is in good condition, individual batteries short-circuit, need to screen;

All in all, after the failure of the electric lithium battery, maintenance is difficult, usually after the sale, the technician is solved by the manufacturer, or the replacement of the same type of electric lithium battery pack.

With half an hour left in the battery, the sponges on the plates absorb water. Then with discharge resistance, the battery, after all, has no resistance and can be replaced with a 12V bulb, such as: motorcycle headlights, car lights can be, as long as there is a discharge effect to 0V. How to determine whether a battery is close to no electricity, the discharge resistance of the cement resistor is hot at the beginning, slowly not hot, when the battery is a power outage, the light bulb is more direct, as long as you see the light slowly not bright, it means the end of the battery discharge. The discharge time depends on the battery discharge ability. We can put the battery in the car for maintenance when there is no electricity, so we can shorten the discharge time.

Repair battery with charger in outdoor ventilation conditions.

Charging batteries can heat up, such as batteries with surface temperatures exceeding 70 degrees, feeling hot, stopping charging, and car chargers.

In this method, the battery activator added to the Nano carbon Sol has been repaired optimally, and the battery life has been extended to even more than one year.

Remember the battery line: the battery is connected in series. The positive electrode of the battery and another battery connected to the cathode.

Carefully open the battery cover plate, the strength must be moderate, do not break as much as possible.

The syringe must go to the syringe. The syringe is metal. The electrolyte that is touched can make the battery obsolete. The syringe head can pick up a 10cm long plastic infusion hose.

The electric car escaped within 10 km and the repair by the above method was ineffective because the panel caused serious wear and tear. (If you want to focus on the public: small copper cell repair)

The sooner you add distilled water, the shorter duration will be. When your electric car duration begins to shorten, the battery will get worse and worse, and eventually it will be ineffective maintenance and scrapped.
