1. Cycle life:
After sufficient electricity, then deep discharge to a certain extent for a cycle. In general, during our use, when the undervoltage indicator light shines, the battery discharge depth is not reached, which is not a cycle whether it is fully charged or half-charged. Qualified battery standard, cycle life shall not be less than 350 times. (It seems that the battery capacity is reduced to 70% of the rated capacity of the cycle, ha ha, can not remember)
2. Deep discharge resistance
At present, the vast majority of electric vehicle batteries are valve-controlled sealed lead-acid batteries. The main reason is that the price is cheap, safe and reliable, stable performance. Maximum use taboo: deep discharge of the battery, it is very easy to cause the plate \"irreversible sulfation\" commonly known as \"plate vulcanization\". It's easy to understand if you look at how battery chemistry works. Resulting in increased internal resistance, greatly reduce the storage capacity and service life.
Remember, don't always use up the battery and then recharge it!!!
Tips: Battery manufacturers use instructions, it is generally recommended that every 2 months, after sufficient electricity, make a complete discharge and then give the battery sufficient electricity. On the one hand, it is intentional to maintain the capacity, and on the other hand, it can check the status of its own battery life.
3, because there are many factors that affect the life of the battery, daily use habits, chargers, controllers, temperature and so on. There is a saying in the industry that \"batteries are not worn out, they are flushed out.\"
Charging is the key, and the length of charging time is subject to many factors. The difference between ambient temperature, charger performance, and the individual battery itself. Sometimes overcharging affects life. Therefore. It is suitable for a single charge when the battery discharge is 60%-70%. Charging time: 4-8 hours in summer, 6-12 hours in winter.
4. After the red light of the charger turns green, it does not mean that the battery is sufficient, at this time, it enters the third constant voltage floating charge stage, and then adds about 1 hour.
(Do not charge after use, and do not charge after use)
First, this situation should be the battery maintenance caused by improper capacity decline, do not want to replace the battery car repair shop to maintain the battery, if the internal plate is not serious, just vulcanization, it can be repaired. If it is the former, then you can only buy a new battery, and pay attention to some when using it later, the life of this consumable battery depends largely on daily maintenance. The general battery is normally used for 1-2 years, and the maintenance can be used for more than 3 years.
2. Charging does not turn the lamp for the following reasons:
1, the charger current is too small, the charging time is long, the battery can not be effectively filled within the expected time, resulting in the charger does not turn the lamp.
2, the charging environment temperature is too high than 45℃, resulting in the battery end charging voltage can not reach the limit voltage value, the charging current is always maintained at a larger value, can not be reduced to the inflection point current value, resulting in the charger does not turn the lamp.
3, the charger parameter Settings do not match the battery, resulting in long-term overcharging or undercharging of the battery, ultimately resulting in battery water loss, charger charging does not turn the lamp.
4. The amount of acid stored inside the battery is too much, resulting in poor oxygen circulation inside the battery, causing \"thermal runaway\" and causing the charger to charge without turning the lamp.
5, the battery memory acid is insufficient, in the late use of the battery due to battery water loss, charger charging does not turn the lamp.
6, the battery internal micro short circuit, resulting in the battery end charging voltage can not reach the limit voltage value, the charging current is always maintained at a larger value, can not be reduced to the inflection point current value, resulting in the charger does not turn the lamp.
Electric vehicle overnight charge is not full of related reasons are as follows:
First, the charger of the electric vehicle has a problem caused by this phenomenon first check whether the charger has a relevant voltage output, if the voltage output is abnormal, or no, it is recommended to replace the charger
Second, the electric vehicle battery problems caused by this phenomenon, most of this situation is the battery attenuation, do not save this situation need to detect the discharge voltage of the battery is normal, if not normal, need to replace the new battery.
Third, under normal circumstances, the service life of the battery is about 3 to 4 years, if it exceeds this service life, it is recommended to replace it in time.
1. Battery life expires
< br >
Even the best battery products have their own life cycle. If the electric vehicle has been unable to charge, we must first consider the battery life problem, the general battery life cycle in 2-3 years, the main factor determining the life is mainly related to the user's use habits.
< br >
Second, the fuse is disconnected
< br >
If the battery's internal fuse breaks, the battery is dead. What to do at this time is to go to a special electric vehicle repair shop or a car store to replace the fuse, do not change yourself.
< br >
Third, poor contact
< br >
When the contact between the safety tube and the safety seat is poor, there will also be a situation where the electric vehicle battery is not charged or is dissatisfied, at this time, the user needs to go to a professional maintenance shop for maintenance, so as to solve the problem of dissatisfaction or failure to charge.
< br >
Fourth, poor contact with the power supply
< br >
Poor power contact is a problem that many users will encounter, 30% of the failure of the electric car battery is from the battery and the power supply caused by poor contact with the electric car is not charged or charged, at this time you need to unplug the charger, plug it back in, the state is in contact with no harm, to see whether the charge is dissatisfied or not charged.
< br >
Five, the line problem
< br >
If the charging line is disconnected or removed poorly, it will also lead to no charging response, and it is necessary to overhaul the vehicle line.
< br >
6. The charger is damaged
< br >
The charger of the user of the Xiudou electric vehicle has failed during use, resulting in battery parameter drift, or has lost the function of charging, although the indicator light will be on, but it has actually stopped working. This requires a replacement charger.
