Is electric car battery repair real?

Electric vehicle battery is the power source of electric vehicle, but it is a kind of consumable. After a period of time, there will be insufficient power. At this time, the battery will generally be replaced. However, some people say that the electric vehicle battery can be repaired. Really? The author tells you! 　　 Battery car battery repair is a matter, but after the repair, the effect is not good, and it can only be used for a period of time. The battery used in the battery car is generally a lead-acid non-dimensional battery. The lifespan is calculated based on the full charge and discharge of the battery 300 times. These 300 times are calculated by reducing the battery capacity to 75% of the nominal capacity. This data is very important because The user will not charge the battery when it is only 75% of its capacity, but will charge it when there is no other way to use it. At this time, the battery capacity has dropped to 40% of the nominal capacity, that is, overdischarge has occurred. The vulcanization process begins after the battery is discharged, and obvious vulcanization will appear after 12 hours. Charging in time can remove non-serious vulcanization. If it is not charged in time, sulfide crystals will accumulate and block the velvety lead micropores in the battery, which will increase the battery's internal resistance and reduce the battery's service life. In this case, use a constant current and unrestricted pulse desulfurization equipment to desulfurize the battery, and at the same time replace the battery water to clean up the sulfide in time. To achieve the purpose of repairing the battery.　　 But after all, it is impossible to remove all the sulfide crystals of the electrode plates, so it can be used for a period of time by repairing the battery, which cannot completely solve the problem. In addition, battery repair is time-consuming and laborious, and the cost of repair is not low. It is better to buy a new battery directly. Previous: What brand of electric car battery is good?
