Electric vehicle battery also "maintenance"

　　Author ：Iflowpower – Portable Power Station Supplier

Electric bicycles have long been a transportation tool for lower income groups due to economic affordable. The largest concentration expenses in the use of electric vehicles are the cost of replacing the battery. Generally replacing a set of batteries, the warranty period given by the merchant is one year, and most of them can be used for 1 year.

Replace a group of 36V (3), the price is about 270 yuan, 48V (4), the price is around 350 yuan, this price is the expense of the old battery. With a set of batteries for 18 months (550 days), the average ride is 20 km per day, and the costs expenditured on the battery are 0.50 yuan and 0.

65 yuan per day, respectively. How to extend the service life of the battery, about the preceptance of the office workers, have the meaning of reducing family expenditure, improving quality of life. There are two aspects to summarize: one is correct use and maintenance.

The second is to replenish the liquid in time, which can greatly extend the battery life of the battery. First, proper use and maintenance 1. Slow acceleration.

Try to keep the speed of the speed of the speed of the speed, the smallest impact on the battery. The author has done experiments, the new battery can drive 60 kilometers or so, if the speed is 25 km and the hour, only about 45 km. 2.

Do not suddenly accelerate significantly in driving, suddenly, the battery strong current is discharged, but not only damage to the polar plate of the battery, but the battery capacity is lowered, the life is shortened, but also easy to burn the key electric door (commonly known as silk tail) Switch contact. 3. Timely charging lead-acid battery properties should be filled with electricity, do not wait for electricity and then charge, this will speed up the vulcanization of the battery pole, so that the battery is lowered quickly, shortened life.

4. Timely supplementary liquid storage battery is electrical energy on a certain concentration of sulfuric acid solution and lead chemical reaction, once the liquid is insufficient, use the medium battery soon heat damage, therefore, timely supplementation liquid is essential. Second, the purchase of the battery 1.

purchase a pure lead-acid battery. The reputable product should be selected according to the experience of multi-year use, the pure lead-acid battery is mature, and the quality is guaranteed. There is a "silicone" battery of the so-called new high-tech material on the market.

Due to the incorrect technology, the quality is unstable, and the problem of indulgence. 2. The option to purchase the upper cover can withstand the battery of the positioning slot structure, because the battery is supplemented with the battery, the upper cover can be extracted, the battery with the positioning groove structure, can be easily opened, and the liquid is plugged into the cover.

Restore. Some batteries are bonded by rubbing, and only use tools when they are added, very easy to get rid, and it is not possible to restore. Third, the related experience skills of the mixture 1.

Supplementary liquid time battery is most afraid of water shortage, new batteries start calculation from the use day, 8 months, to supplement the first liquid to the battery, this period, if it is just hot summer So 6 months, should be supplemented. After each 4 to 5 months. 2.

Source of liquid is recommended to use a set of acid solutions, better effect. When the battery is replaced by each repair point, the merchant generally promises to add a liquid for the battery for a year. It can bring two air mineral water bottles, discuss with merchants, two bottles of battery manufacturers with battery packs, the conditions are no longer asking merchants in the future, merchants are generally willing, because they will not be troublesome.

After the acid is brought home, it should be posted on the label, indicating that the acid, keep it safe, do not let the child contact, so as not to occur. 3. The step of adding liquid first adds the liquid to add this original supporting acid solution.

Each battery has 6 units (6 grid), 5 ml of each storage battery, can not add more. The step is to open the battery case, use 50W iron iron to weld all the cables, take out the battery one by one, the word is released, push the upper cover, use the tweezers to cover the rubber cover of each bottle mouth. Be careful when taking the rubber cover, sleeping nitrile does not be pair of bottles, because there is pressure in the bottle, it is possible to suddenly flush the rubber cover and eyes, it is best to wear protective glasses.

At the same time, the white asbesto felt in each bottle groove (used to absorb the spilled acid solution) is placed. Put the acid solution in the mineral water bottle in a hot half bowl in a clean porcelain bowl, the purpose of doing this is not easy to turn, guarantee safety. Then use the large syringe (equipped with large needles, pharmacy for sale), extract 5 ml of acid solution in a bowl, and take the needle stretch battery bottle mouth, pay attention to not too deep, so as not to damage the internal structure of the battery, slow liquidity eight.

Every time you add a record immediately. No. to avoid repeating liquid or leak liquid.

After adding the liquid, wipe the battery with cotton cloth, then put it back to the stone felt, cover the cover, plug in the cover, restore the original. When welding, the time should be as short as possible, so as not to burn the battery pile head, but it is not possible to fake welding, especially pay attention to the positive and negative polarity of the battery series. The third addition is no additional acid, because the battery is only evaporated in the battery, and the acid is still retained in the battery.

It is deficient that water is not acid. If the acid is added, the concentration of the acid is greatly increased, which will damage the battery. From the third time, add liquid only to the distillation water.

If the distilled water is not easy to find, you can buy pure water instead of the supermarket, pay attention to the mineral water containing mineral water, only pure water. The author uses Le Bai's pure water. According to the author's practices, this time and method are battery supplementation liquid, which can extend the life of the battery 12-18 months.

Fourth, the processing of batteries with significant decline Some batteries have no timely supplementation liquid, and the capacity is significantly decreased, and the riding is dead, and it is full of half an hour. This battery is in use for more than 2 years, generally has no value, and can only replace new. If the use time is within 1 year and a half, the following method is used, the capacity can be resumed twice, and the battery can reach 15 kilometers.

If there is a conditional one-way charging, it can meet the requirements in the urban area, continue to use 6 ~ 8 Month. About this battery due to improper maintenance, the capacity is significantly reduced, and some battery cells have a carbon black, and there are many precipitates. This should first rinse first.

Washing method is to pull out all the liquid in the bottle by needle tube, and then quickly inject the pure water into the bottle with needle tube, and then pull it out, repeat several times until each battery is flushed into the water Without black precipitate, finally exhaust water in the bottle, wait for the effusion. Still in accordance with 5 ml of each grid, the eight-fitted acid solution, all batteries are added over again, stand for 20 minutes, observe with flashlight, the liquid should have just drown the polar plate, if the liquid is insufficient, then add 3-5 Milory until the liquid is just overwhelming. .
