Bothater repair has two method repair machine repair and battery refurbishment. Battery repair machines can not be repaired, just like people, if they are sick, not all diseases can solve problems, but also surgery can cure, and they have cancer can't be cured. It is not possible to repair, broken, unprocessed, perforated, etc.

, can repair it with a repair machine, like this battery must be refurbished, open the battery cover, change the polar plate, the partition, plus Wait for liquid, in order to repair battery. The battery detector can be repaired by battery detector before we repair the battery. If you can fix it, use a battery repair machine or a battery refurbishment.

Battery vulcanization is manifested: the battery itself is low, and the charging will be full, and it will be no. Battery softening is: the internal liquid is turbid, black. The battery capacity is reduced, and the time is over and the lead powder falls off.

The battery is open (broken, the soldering) is manifested: the measurement voltage is 12V when the battery is stationary, but the large current discharges, the voltage is 0V. The battery is short-circuited to: discharge the battery with the discharge device, if a single lattice has bubbles And the other basic did not, explain this lattice. If the battery is not electrified, the discharge instrument is discharged, it doesn't make sense, because you can't see if the battery is broken, pay attention to the break of the battery only in the case where the battery is powered.

The battery is small, the power supply capacity is small, the output is not large, can not be used for large currents such as automobile boots, slightly discharged, the voltage is decreased, and after charging, for small power equipment, it is still used in a short time OK, if you place it for a while, the battery is not electricity. The battery is repaired, only for the battery of the polar surface, is not a broken, off-chooled battery. You can go to the "Koi" battery repair network to see it, there is video.

1. Unbalanced repair method: find out the battery, voltage, self-discharge, battery internal resistance, etc. 2.

Water repair method: open the cover above the battery. Some battery covers are ABS adhesive, some batteries are connected to. Some is a skateboard.

Note that when you open the cover, don't damage the cover. At this time, you can see the rubber cap of 6 exhaust valves. Open the rubber cap, expose the exhaust hole, can see the inside of the battery through the exhaust hole.

Some battery exhaust valve bases can be rotated, and can be rotated open the exhaust valve base without opening the rubber exhaust valve. Some fillers around some batteries. Open the cover, use the flashlight, see if there is a dry phenomenon in the small hole, that is, the battery is lost.

The polar plate of the battery is wrapped with white glass fiber cotton, and the normal situation should be humid. Insert distilled water with a dropper is injected into the battery from the exhaust hole. Cover the exhaust hole with a breathable shutter to prevent dust from falling into the exhaust hole.

It is best to use medical secondary distilled water. The principle of hydrating is Ning less than many. Not enough, more, more acid specific gravity decline, battery capacity is less.

No experience can be grasped by 5ml each well. It is best to look at the plus, wet, bright crystalline, Water Wang. Wet is just right, bright crystals, and the water is too much.

Special note: hydrating tool uses straws such as glass, plastic. It is recommended to use medical disposable syringes, easy to use and convenient. The hydrating tool does not use any metal-containing instrument, the syringe should be pulled to the metal needle, and the plastic tube is used.

3. Sulfate repair method: repair the vulcanized battery to repair the Kuye repair instrument, using a fuzzy digital control theory, by measuring the battery status, when charging, discharge, continuously issuing positive and negative frequency conversion microparticles, with 10 to 20 hours Time, remove hard sulfate in the battery. 4.

Polar softening repair method: After the battery is discharged from 10.5V, use the bulb deep to discharge 1-5 hours. Then use the activator, activation repair.

5. Short-circuit repair method: water battery, can make a clearer, make the short-circuited lead powder! Electric vehicle battery can quickly short-circuit the positive and negative poles, and boil the place for the short circuit! 6. Opening repair method: 100A Detect battery voltage 0V is open, using a single measurement method, the place where the opening is measured, the welding is good.

Wanwei can measure the battery opening of the battery! The battery is used, and the battery repair is just maintained its normal design life. Procure the battery repair product to repair any factor damaged battery to the new battery, ensuring how many times the battery can extend, and these are not scientific, and it is not practical. A battery damage that has no factor has an impact on the battery life.

How is the problem how to reduce the damage of the battery, how to reduce the effects of battery life, and simply introduce several electric car battery daily maintenance methods for users to reference. First, constitute distilled water. The user is generally thought that the maintenance-free battery does not have to add water, in fact, this kind of saying is wrong.

The maintenance-free battery will generate heat during charging and large current discharge. If there is heat, there will be water evaporation, although the process of water evaporation is very slow, but the time is long, the amount of cumulative water evaporates is not small. Therefore, every 6 months should give the battery once, so that the battery life will be extended.

Second, to "daily car, charge every day". Lead-acid batteries have no memory, so the capacity is rapidly reduced is mainly for some reason for battery vulcanization and "loss of water", "losses", and the battery is most feared is "loss of electricity" under pressure, battery is often "lofinish", battery pole The plate is extremely injured. We investigate that there are 70% of the electric vehicle battery capacity to reduce the strong current (start current) strain when the electrode plate is discharged (the electric motor is particularly obvious), and the electrode plate strap belongs to the battery physical damage.

This kind of damage cannot be repaired. Therefore, "daily car, charge every day", ensuring that the battery has sufficient voltage at any time. Third, often observe the quality of the charger.

The new battery charging process is generally 6-8 hours. After the charge is filled, the charger will be bright green. If the charging time is too long, check whether the charger voltage protection device is bad, if the bad loss needs timely exchange charger, Otherwise, very easy to let the battery.

In addition, do not buy a fast charger, fast charging, also hurts the battery pole plate. Fourth, electric car starts. Electric cars start current, especially the electric motor of the high-power motor, the start current is larger.

The large current is very hurting the battery polar plate. The best way is to start the electric vehicle power after starting the same cycling before starting the bike. Of course, many electric motors don't have a riding device, this has no way.

Five, use the battery protector as early as possible. The battery protector is also a pulse generator, which has caused the vulcanization of the pulse until the pulse is uninterrupted, so that the polar is always "clean", thereby achieving the effect of extending the battery life, but the major current damage battery polar plate is not large (if there is The electric motor is used to use a pulse charger, and the resulting battery extension is not obvious), and new technologies must be improved. Sixth, discharge the battery depth of the battery once.

The battery will inevitably have some active substances after using a period of time, and if the active material is not activated in time, it will inevitably affect the capacity of the battery, so when using electric vehicles often use electric vehicles, it is necessary to do a quarterly battery Deep discharge. 7. When you don't use the battery for a long time, you must charge the battery once a month.

The purpose of doing this is to prevent the battery from being deployed too long and causes battery vulcanization and "loss". 8. Prevent battery explosion.

Blasting will increase the temperature of the battery, so pay attention to. .
