About the maintenance of electric vehicle batteries

Regarding the maintenance of electric vehicle batteries, this is currently the most complete solution! How to use and maintain electric vehicle batteries has always been a hot topic for us. We often ask, do you want to charge the battery you just bought? How do you usually maintain it? Therefore, the author has compiled some information and shared with you, hoping to help you after reading it. Why is it necessary to compensate for the battery charge before the first use? The battery used from the factory is generally 1-2 months or even longer. During the battery storage period, due to the internal self-discharge of the battery and other spontaneous reactions, a part of the battery is consumed, Therefore, before using the best compensation charge, in order to prevent the misunderstanding that it is insufficient capacity. If an electric vehicle is to be stored for a long time, how should the battery be handled? First, the battery should be stored in a fully charged place and should be charged at least once a month to prevent power loss and effectively prevent the formation of irreversible salinization and alkalization. Short-circuit the crystal. Do you want to use up the battery before charging? Unlike other secondary batteries, lead-acid batteries have no recall effect, so no matter what state of charge the battery is in, it can be directly charged without discharging. Is the frequently charged battery okay or is it better to put it after charging? There are many chargers currently in circulation on the market. Due to the price factor and technical level, the charger has defects such as high failure rate, poor reliability, and low accuracy. Therefore, sometimes frequent charging will affect the service life of the battery. If the battery is emptied and recharged, although the number of recharges is reduced, there are always differences between the single batteries during the discharge process, which may form some single-cell power grids. Over-discharge, thereby greatly reducing the charging capacity of the over-discharged battery, leading to the problem of insufficient charging. Others, because the charging power source cannot be released, the charger has a heavy load for a long time, and the charger is easy to damage. Therefore, in summary, we believe that it is more reasonable to charge the battery when the battery emits 50-70% of the power (that is, when the electric vehicle is traveling about 30 kilometers), which is beneficial to the use of the battery. What are the disadvantages of charging more and charging less? The charging current of rechargeable batteries is greater than that of current batteries, and they are more responsible. Some of the side-use charges of electrolyzed water are important attacks and attack oxygen transfer. Since the positive and negative electrodes of the battery attack the oxygen compound reaction, heat can attack. Therefore, the rechargeable battery converts into heat to make the actual temperature. If it is not controlled, it will form a large amount of water and deform. Undercharge means that under the condition of undercharge, it will gradually form a thick layer of consolidated lead sulfate, which is almost insoluble, which is the so-called irreversible sulfuric acid, which is generally used. The method cannot be charged, so the capacity will quickly decay. What are the hazards of overdischarge to the battery? During the discharge of the negative active material of the battery, the negative active material gradually enters the high resistance PBSO4, sulfuric acid and cost, and the electrolyte resistance gradually increases, so after discharge, especially in the high current discharge Announced a lot of heat, and a small amount of sulfuric acid in the battery discharge reduces the sulfuric acid concentration is very low, when the solubility of PBSO4 is greatly increased, so simply form a huge solid PBSO4 crystal on the plate, that is, irreversible sulfate greatly weakens the battery's charge acceptance ability , Especially the big damage. Do moped batteries need to be refilled with water? Generally speaking, do not refill liquids. Lead-acid sealed batteries for electric bicycles are valve-regulated sealed batteries. Oxygen compound reactions occur during normal operation, so water consumption is very small. Do not add electrolyte or water during normal service life. However, due to the operating environment conditions and charges, some batteries may lose a large amount of water or even attack the phenomenon of swelling. At this time, electrolyte or pure water should be added, and the electrolyte density is 1.05 g/cm diluted sulfuric acid or pure water ( Distilled water), so that the more serious the battery returns to normal from the beginning. Under what circumstances should the electric vehicle battery be charged? 1. The battery capacity decays too fast; 2. The battery is out of date; 3. After the battery loses its liquid, it is recharged from the beginning; Statement: Some pictures and content of the articles published on this site are from the Internet, If there is any infringement, please contact to delete the previous article: What are the uses of battery aluminum foil in batteries?
