1, the power supply contact is poor
< br >
This is a very easy event, according to the survey data show that 30% of users will not charge the electric vehicle battery because of poor contact with the power supply or is not charged, at this time what needs to be done is to unplug the power supply, plug it back in, ensure that the contact is not bad, and then see whether the charge is not satisfied or not charged.

2. Poor insurance contact
< br >
When the contact between the safety tube and the safety seat is poor, there will also be electric vehicle battery charging or charging dissatisfaction, at this time, the user needs to do is to adjust the position of the two, so that it is in good contact, so that it can solve the problem of charging dissatisfaction, or charging failure.

Two, disconnect
< br >
When the circuit board in the dial is broken, it is very normal that the battery is not charged or the electric vehicle battery is not charged. What to do at this time is to replace or repair the circuit board to ensure normal contact.
< br >
Three, the fuse is blown
< br >
As we all know, if the fuse in the switch is blown, the power will definitely be lost. Similarly, if the fuse inside the battery is blown, the battery will be dead. What to do at this time is to go to the store to replace the fuse, do not change yourself.
< br >
Four, the positive and negative poles have problems
< br >
According to professionals, when the plug-in in the battery is in poor contact or the lead is broken, it will also lead to no voltage, especially if the connection between the positive and negative dial is normal, the impact on the electric vehicle battery is also great. You can reconnect the cable or replace the cable.

5. The charger is damaged
< br >
Some users are used to carrying chargers with the car, and because of bumps, the phenomenon that the charger is damaged and unable to charge is also very easy to occur. So it is very important to check whether the charger is normal. In the case of no charging, be sure not to connect the electric vehicle charger to the AC power supply for a long time, and it is strictly prohibited to open the power lock of the electric bicycle when directly charging the electric vehicle to prevent burning the charger.

Battery life is up
< br >
No matter how good the product is, it can not be used for a lifetime, so when you find that the electric car battery is charged, you should carefully recall how many years it has been from purchase to use now, whether it is within the normal range of years, if it has exceeded the number of years, then it should be replaced or repaired in time.
(1) Due to the self-discharge phenomenon of lithium batteries, if the battery is not used in order to obtain long-term good preservation, the battery voltage can not be lower than its cut-off voltage, preferably around 3.8-4.0V;
< br >
It is recommended that the lithium battery be charged once in half a year, so that the battery has been kept above the cut-off voltage;
< br >
③ The temperature and humidity of the battery storage environment should be appropriate, and the operation should be in accordance with the specifications;
< br >
It is best not to put old and new batteries, different brands, capacities, and types of batteries together to charge or mix them into battery packs
Go to a regular battery manufacturer to buy a new battery
The ability of lithium batteries to store electricity after a certain number of uses will be greatly reduced, and the driving range will be greatly reduced. If it is not used for a long time, it will also reflect the efficacy of the battery. The service life of lithium batteries is generally two to three years.
If the good use effect can not be achieved, it is necessary to replace the new lithium battery in time, and do not overcharge the battery resulting in unnecessary accidents
Introduction to the correct use of mobile phone lithium battery: First, do not carry out more than 12 hours of ultra-long charging. For the \"activation\" problem of lithium batteries, many say that the charging time must be more than 12 hours, and it must be repeated three times in order to activate the battery. This \"the first three charges to charge more than 12 hours\
Charging is best in accordance with the standard time and standard method of charging, especially do not carry out more than 12 hours of ultra-long charging. Usually, the charging method described in the mobile phone manual is the standard charging method suitable for the mobile phone. Second, put the lithium battery in a cool place. The high charging state and the increased temperature will accelerate the decline of the battery capacity, if possible, try to charge the battery to 40% and put it in a cool place, so that the battery's own protection circuit can operate during the long storage period.
If the battery is placed at a high temperature after being fully charged, it will cause great damage to the battery. (Therefore, when we use a fixed power supply, the battery is fully charged at this time, and the temperature is generally between 25-30°C, which will damage the battery and cause its capacity to decrease). Do not expose the battery to high temperature or cold, like the dog days, should not put the mobile phone in the sun, to withstand the sun exposure; Or take it to an air-conditioned room and put it in a place where the cold air blows directly. Third, avoid recharging after all battery power is used up. The life of the battery is determined by the number of repeated charge and discharge, lithium batteries can be continuously charged and discharged about 500 times, after which the performance of the battery will be greatly weakened.
Should try to avoid all the remaining battery discharged and then charged, otherwise with the increase in the number of charging, the battery performance will slowly weaken, the battery standby time is difficult not to decline. 4. Use a special charger. Lithium-ion batteries must use dedicated chargers, otherwise they may not reach saturation, affecting their performance. After charging, it should be avoided to place on the charger for more than 12 hours, and the battery should be separated from the phone when it is not used for a long time, and it is best to use the original factory or reputable brand charger.
