The new year is coming, many electric vehicle users due to a long time has not used the electric vehicle, there is a situation that can not be charged, that is, we often say how to repair the lead-acid battery broken?
1. Use a charger with repair function to charge
The first method you can try is to use a charger with a repair function, many electric vehicle chargers now have a repair function, and as long as you use this charger to charge, there is a certain chance that the battery can be reactivated. Of course, it takes many attempts, and another personal suggestion is to push it to the repair shop to let the maintenance master try, don't buy the charger yourself, so that the cost will be lower, and the safety will be higher, if you really can't charge it, then try the second method.
2. Turn on the high beam to charge
Secondly, the method that can be tried is to turn on the high beam to charge, which is often referred to as charging with the headlights. To put it simply, turn on the headlights to charge when charging, but here, you can try with a normal charger first, and then change to a charger with a repair function if it doesn't work. In addition, try to ensure that the electric car can be charged normally, and then turn off the headlights. Similarly, it is recommended to go to a repair shop and let the repairman operate it, which is safer, and there is no need to buy a charger with repair, and the cost is lower. From a practical point of view, many users can reactivate the battery, but there will also be a small number of users who cannot activate the battery, so it is necessary to start trying the third method.
3. Try the pulse repairer repair
The third method that can be tried is to use a pulse repair device. To put it simply, the battery cannot be charged, and there is a high probability that it will not be used for a long time, and the plates will be vulcanized, so we can push the car to a professional repair shop and let the maintenance master repair it with a pulse repair instrument to repair it and remove the sulfide crystals, so that there is a high probability that the battery can be reactivated. However, this method lasts for a relatively long time, and it is necessary to find a professional repair point to have such an instrument.
In short, if the user has not used the electric vehicle for a long time and the battery cannot be charged, then you can first ask the maintenance master to try to use the charger with repair function to charge and turn on the high beam to charge, which can basically solve the problem of some users not being charged. But if these two methods do not work, then you need to try fundamentally, that is, go to a professional repair shop and try to repair the pulse repair instrument, and there is a high probability that the battery can be repaired again.
However, it should be noted that if the battery cannot be charged, it is best to go to the repair shop to operate, after all, if the first two methods are feasible, the cost of replacing the charger with repair can be saved in the repair shop, and the safety will be higher. And the third way is that you have to go to a professional repair shop to solve it. And to do the above three points, there is a probability that the battery can be repaired. Of course, the above is only applicable to lead-acid batteries, and it is only personal experience and opinions, for reference only, how to operate, how to choose, you need to measure yourself.
