An activation method is to find a group of electric vehicle lithium battery with the same model as the primary battery, and connect it with this group of batteries that cannot be charged, so that the good battery discharge to the battery that cannot be charged, after several cycles of parallel charging, there is a certain probability that the battery can be reactivated.
The second activation method is to use a small charger to charge this set of lithium batteries first, and then change the original charger to continue charging. For example, the battery that can not be charged is 60V, you can first charge it with a 48V charger, and then change to the original 60V charger for charging, so that there is a certain probability that it can be activated.
The third activation method is to try to quickly charge for one to two hours, and use a professional detector to see if there is an increase in voltage, if there is an increase, you can choose to continue charging with the original charger, so that you can activate the electric vehicle lithium battery pack.
The fourth method if the electric vehicle lithium battery pack is more serious, then the activation of the battery is not effective, only by changing the battery to solve the charging problem.
The fifth method is that if the electric vehicle is not used for a long time, the electric vehicle lithium battery pack should be fully charged and placed, and it should be noted that every other month, the battery should be charged once, in addition, the battery switch should be disconnected, or the battery plug should be unplugged. Because in addition to the self-discharge of the battery, the placement of accessories such as controllers will also lose power. In this way, the battery can be protected to the maximum extent.
