In response to the voice of netizens, the author experienced it. Netizen Burning Liang Yong is now posting "Adding Water to Electric Vehicle Batteries", which is a friendly contribution for the reference of [electric vehicle lead-acid battery riders]! Precautions: 1. The charger does not turn green after charging the battery for one night (please make sure that it does not turn green after changing to another charger! ), the battery is hot and hot. However, the endurance has not decreased significantly during driving, and the battery function can still be played normally. (In short, the short-term battery can only be recovered by adding water! ) Second, the online video tutorial of adding water taught me to buy a "repair instrument" on their website to repair it after adding water. The answer is: nonsense! -I didn't cheat you into buying their so-called "restorer"! Don't make logical mistakes-most of the better chargers on the market have their own so-called "repair" function! Third, be sure to discharge the battery of the electric car! (Exhaustive method: 1, the bike is too hard to ride! Then put your big feet on the car and fix the throttle handle to the maximum with transparent tape! Turn the wheel straight until there is no electricity! Also turn on all the lights and turn signals to speed up its power consumption! Until the wheels stop turning and the lights are still on, forget it, forget it. The battery can be detached from the electric car and "dismembered"! Fourth, add less water than more! Don't add it indiscriminately! V. Prepare tools before adding water: 1, 502 glue (3 yuan, a small bottle is enough! )。 2. Cross screwdriver. 3, a word screwdriver. 4. Medical syringe (I bought 10ML! Not in an ordinary drugstore! He won't buy it for you if he has it-he's afraid you'll make a terrorist attack! Go to a bigger stationery store to buy it! 5. Watsons, a bottle of 400ML Watsons distilled water is the small bottle you saw in Meiyijia! I bought D, which is from Dongguan. You can buy it from other places. In short, it is Watson's distilled water! 6, small flashlight, I used a Nokia 1280 mobile phone with flashlight function! Just think of it as a flashlight) 7. A roll of scotch tape for use. 6. Remove the battery case with a Phillips screwdriver. You will see the 12V battery that is common in five motorcycle repair shops. In short, each one is 12V, and of course there are five 60V electric cars, 5 * 12 = 60! There are only four 48V models, and so on! They are battery packs in series! Seven, the series line of the battery pack does not need to be dismantled! To avoid trouble! But be careful with your hands and any conductive objects, and don't let their positive and negative poles cause any short circuit! Eight, slowly pry the cover of one of the small batteries with a screwdriver, and then slide it out: note that the cover and the battery body are interlocked, so you can observe it carefully! And the general battery manufacturers are also very painful, not only biting, but also adding a small amount of glue! That is, adhesive. So I want you to pry it gently first. Maybe impatient netizens will pry open the lid of the first battery! -Never mind, stick them with your 502! Really can't. Finally, after adding water, we can cut a thick paper of the same size instead of this rotten rubber. After opening the rubber cover of this small battery, we will see that there are six water inlets, all of which are covered with rubber caps. Gently open these six hats one by one, and then illuminate them one by one with a flashlight to observe the dry and wet conditions at the bottom of each water inlet, so as to determine the water shortage of each water inlet. Wet means there is water (note that when we say water, we don't mean there is much water. Our term means "wet", which means there is water, so there is no need to add water! In fact, rechargeable batteries with heat are usually not too "wet"! Moreover, it may be "dry"! So we have to add them until they are "wet"! Attention, you can't see the added water! But it depends on "wet"! If you see water, you have gone too far! Cardo! Suck out excess water with cotton cloth! Ten, well, what we see is dry, not too wet, then we will inject 4ML of water into the dry mouth! Don't extend the metal syringe too deep when adding water! In order to avoid unnecessary short circuit when touching the electrode inside! Please hold the syringe with both hands to inject water to prevent hand shaking! ) It's already a little wet. Let's inject 2ML of water into it! Please use a flashlight to look into the battery from the water inlet to see the dryness and humidity inside! ) After adding water, put back the caps at each port in time to prevent dyes in the air from entering the battery! Then cover the small battery. Glue the cover with 502, sweep it dry and then cover it. It is suggested that all the covers be cut with a little scotch tape and adhered to the battery body. So as to prevent the small battery cover from falling off during driving. It is also convenient for the next disassembly operation with water. Twelve, well, after the operation of adding water to the small battery, other methods of adding water to the battery can be imitated by analogy! Thirteen, well, after all the small batteries are added with water, let the batteries stand for 12-24 hours, so that the water we added can completely penetrate into the electrodes. Don't stand with the water inlet of the battery facing down! It must have gone up! In other words, don't turn the battery upside down. Fourteen, 12 hours later, we put on the battery and charge it. You will find that the battery turns green after charging 12 hours! It won't be hot again and it won't be hot again! Fifteen, the author's experimental results show that only about two-fifths of 400ML Watson's distilled water is added at last. The author's is a 60V lead-acid battery. There are always five small batteries in the battery pack. Sixteen, the author finally suggested that if your battery also has this disease, please do it yourself. Compared with others, the so-called maintenance center tells you that it will cost a lot of money to replace it all, and it is far less careful than doing it yourself. Network writers "burn forever" sincerely wish the end of the year. Thanks for watching!
