What are the reasons why the battery is not fully charged

1. An illusion caused by abnormal charger indicator Some users are used to carrying the charger with the car, and the phenomenon that the charger is damaged and cannot be charged due to bumps is also very easy to occur. So it is very important to check whether the charger is normal. When the battery is not charging or is not fully charged, do not connect the charger to the AC power source for a long time without load, and it is strictly forbidden to open the power lock when the battery is charged directly to be careful to burn the charger. In this case, you can consider replacing or repairing the charger. 2. If the rainwater is broken in the battery fuse, it is easy to cause a short circuit of the power supply, and then burn the battery fuse. When the battery is damp, the most easily burned out is the controller. Remind everyone that it is necessary to take waterproof measures for the controller on rainy days to guard against rainwater; the exposed wires should also be covered with rain gear to guard against short circuits in local lines; in addition, do not drive in stagnant water. If there is something wrong with the battery display, cut off the power immediately. In this case, just replace the fuse straight. 3. End of battery life. In this case, you can go straight to a professional repair shop for testing and repair. In fact, the maintenance of the battery is also essential in daily use. Newly bought batteries have to be overcharged and reused. This concept is wrong! When the overall battery capacity is about 30%, it is the best time to charge the electric vehicle at this time, and the charging time should not exceed 12 hours, and beware of battery overcharging. What to do if the battery cannot be charged 1. Check the battery to see if the wiring is loose and the connection is not secure. 2. If the circuit is normal and still can't get in, you can see if the circuit board of the battery charger is broken and try another one. 3. If the line is normal and the charger is good, it may be that the circuit board inside the computer is malfunctioning. 4. It is also possible that the battery has aged. Generally, the battery is used for about 3 years, and it is basically aging, even if it is a lithium battery. Go to the repair shop to check it. 5. Generally, you have to wait until the battery is used up to about 20% before charging. Don't wait until 0 o'clock, which will damage the battery too much. 6. Rescue small way: put the battery in a napkin, pay attention to several layers, and then use a translucent twisted cloth to stick it on the outside, pay attention to use the twisted cloth to stick tightly, do not let the inside permeate, and then put it in the refrigerator (2 -2 degrees Celsius below zero) Take it out after 72 hours of storage, the battery may restore part of the storage function.
