In general, battery water can be divided into two types. One is a battery filled liquid, which is a mixture of sulfuric acid and purified water, and has a density of 1.28 g/cm 3 (20 ° C). One is a battery replenishing liquid, which can be pure water, deionized water and distilled water. Its role is to supplement the water lost during battery use. The most used ones are clean, and the market is very large.
Battery repair solution is also called lead-acid battery repair solution, battery activator, battery capacity enhancer, etc. Added to the failure of electric vehicle battery, can restore the battery capacity, extend the battery life, improve the battery performance of a solution. No need to repair professional equipment, simple and easy to operate. Due to the different composition of the repair fluid, the repair effect is different. After the battery is added, the battery capacity is restored after a complete charge and discharge, and the distance can be increased by 5-15 kilometers. After seven times of complete charge and discharge, the battery capacity is restored to more than 90%, and the service life is extended by about one year. After all the batteries have reached a certain life limit, various failures and failures will occur. Some failed batteries add repair fluids that can be repaired, and some problems are severely scrapped. According to the national standard for electric vehicle batteries (JB/T10262-2001), the capacity is less than 70% of the nominal capacity for the failed battery.
1. Inorganic salt battery repair liquid: alkali metal and alkaline earth metal sulfate, phosphoric acid, cobalt sulfate, cadmium sulfate, stannous sulfate, copper sulfate, zinc sulfate, nickel sulfate, aluminum sulfate, etc., these alkali metals and alkaline earth metal ions The lead ion in the lead sulfate crystal is replaced to increase the concentration of lead ions in the electrolyte, and the active material participating in the electrochemical reaction is increased, and the capacity of the battery is improved. However, such repair fluids cause self-discharge to the battery, and alkali metal and alkaline earth metal ions may pitting the battery plates to cause battery damage. This kind of repairing liquid only has an effect on the vulcanization of the battery plate, and it is ineffective for softening and peeling off the plate. The repaired battery can last 2-3 months.
2. Organic compound and complexing agent battery repair solution: amino acid, citric acid, tartaric acid, amine, alcohol, ether, EDTA, etc. Organic compound and complexing agent can improve the concentration of hydrogen ion in the battery electrolyte; Increase the terminal voltage of the battery, improve the electrochemical reaction speed; Complex impurity metal ions, reduce battery self-discharge; Increase the capacity of the battery. This kind of repair solution has little effect on the curing, softening and peeling of the battery plate, but it can slow down the battery failure, and the battery can be used for 2-3 months after repair.
3. Nano-carbon sol battery repair fluid: Small coppersmith nano-carbon sol is a type of nano-carbon material. A nano-carbon material refers to a carbon material having a dispersed phase dimension of at least one dimension of less than 100 nm. Under the action of electric field, the active component of the activator can solidify the plate; disintegrate irreversible sulfate crystal; uniformly adsorb on the surface of the plate to form a protective film to prevent the active material of the plate from falling off and the plate vulcanization, polarization, lead The formation of crystallization; activation of the active material of the battery; reducing the internal resistance of the battery, and improving the electrochemical reaction of the battery. This kind of repairing liquid only has a better repair effect on the battery, and the repaired battery can be used for more than 12 months.
1. Battery screening:
(1) The electric vehicle travel begins to shorten (or the battery capacity is not less than 70%), indicating that the battery begins to lose water and vulcanize, and should be hydrated or added with a small coppersmith nano-carbon sol battery activator.
(2) The electric vehicle stroke is shortened by half (or the battery pool is not less than 50%), indicating that the battery plate is severely vulcanized and slightly softened. A small coppersmith battery repair solution should be added immediately.
(3) The electric vehicle stroke is shortened by more than half (or the battery capacity is less than 50%), indicating that the battery plate is vulcanized and softened. Adding a small coppersmith battery repair solution is not obvious, and it can be repaired together with various battery repair instruments.
(4) The electric vehicle stroke is shortened by 3/4 or more (or the battery capacity is less than 30%, the battery shape is drum, leaking), and the repair is abandoned and discarded.
2. Add method:
1. Adding tools: Generally, use a syringe to inject (to remove the needle of the syringe) to install a plastic tube or use a non-metallic device such as a plastic funnel.
2. Adding steps: (1) Open the exhaust valve of the lead-acid battery, which can be roughly divided into two types: one is split type, which is to open the vent cover with sharp instruments; the other is open type Is to force the vent cover to open.
(2) Fill the battery vent according to the additive amount of the repair solution. If the battery loses water seriously, add the replenishing solution after adding the repairing liquid to the inner diaphragm of the battery. It is strictly forbidden to use ordinary drinking water or inferior lead-acid battery replenishing liquid. Otherwise it will cause serious damage to lead-acid batteries.
(3) Install the battery vent cover and let it stand for 2 hours. The longer you let it rest, the better it will be.
3. Repair method:
1. Ordinary user: Install the battery car after the repair liquid, and run the battery. Fully charge with the car charger and then run the battery to discharge, one charge and discharge for one cycle. Generally, one to three cycles of battery capacity are restored, and a serious seven cycles can be recovered.
2. Professional repair shop: The battery after adding the repair liquid is discharged in series or in a single form, (can also be discharged by DC bulb) to 10.5V or 0V, and then charged with various pulse battery repair instruments, or used The constant current charger charges for 12 hours with a current of 0.3C and a voltage of 17V (single battery repair). The battery capacity is restored once and for all.

1. Use: easy to operate, add directly.
2. Effective results: The day is effective, and the recovery is as new as seven days.
3. Long life: After repairing, the battery has a long service life of one year.
Battery capacity and longevity are important indicators of battery performance.
Capacity: It is the ability of the battery to store energy, generally expressed in AH. For example, a new set of 12AH36V batteries, according to industry standards, must reach a current discharge of 6A, discharge to a final voltage of 31.5V for not less than 2 hours. This battery is used in electric vehicles, with a load of 75 kg, running on a flat road, working current is 4A, discharge time should be more than 3 hours, speed is 20 kilometers per hour, and the theoretical continuation is 60 kilometers.
Lifetime: It is an indicator of the battery capacity decay speed. According to the new standard for electric vehicles, the battery life is up to the rated capacity of 70% of the charge and discharge cycles. The qualified bottom line is 350 times. Under normal conditions, a good battery life should be no less than 1 year, generally 1.5 years, properly maintained to more than 2 years.
