Ten Questions and Ten Answers to Electric Vehicle Battery Maintenance

Due to the advantages of low carbon, environmental protection, convenience and speed, electric vehicles are deeply loved by consumers and are becoming more and more popular. And the power source of the battery as an electric car is equivalent to the human heart. Only when the heart is good, the electric car can go further! 　　 So, how to maintain the heart of the electric car? Next, Xiaoxu will take everyone to take a look! 　　 1. Electric What should I do with the battery when the car is parked for a long time? 　　 is very simple. To protect the battery, we can store it after being fully charged and charge it at least once every other month. This can effectively solve the irreversible salinization and short-circuit formation in the battery. Wait.　　2. Is it necessary to empty the battery before charging? 　　 Just like mobile phones nowadays, there is no need to completely empty the battery of an electric vehicle, and then recharge, you can charge it at any time.　　3. Does the battery need to be recharged for the first time? 　　This is necessary. Generally, it will take about 2 months or even longer for the battery to be used from the factory. It will naturally consume a part of the power during storage. Therefore, it is necessary to recharge the battery to avoid mistakenly thinking that the battery capacity does not meet the power indicated in the manual. 4. Is overcharging or undercharging harmful to the battery? 　　 Yes, not only is there, it is also a great harm! Overcharging exceeds the rated current of the battery, the most direct impact is the increase in battery temperature, causing a large amount of water loss for a long time, and even serious There will be deformation failures. If the charge is insufficient, the harm is that in the long run, the capacity will become smaller again and again, which gives us the feeling that the battery is becoming more and more non-disabled.　　 5. The battery is often charged and discharged, which is more beneficial to the battery? 　　 Both of them are not good to the battery. The battery is often charged. If you encounter a good battery of high quality, it is okay. Charging frequently helps to protect the battery life. However, for the batteries circulating in the market, except for brands such as Chaowei batteries, the failure rate is low and the quality is low. In addition to stability, most of them have various problems. Excessive charging will hurt the root cause and affect the battery life. It is not good to recharge the battery after emptying it, because the battery load time is long and it is easy to cause damage to the battery. 6. Is there a direct relationship between voltage and capacity? 　　 does not! Voltage is voltage, and electricity is electricity. It cannot be said that high voltage means high capacity, and low voltage means low capacity. However, under load, battery voltage is related to battery capacity. It can even be said to be proportional. 7. What are the hazards of battery overuse? 　　 If the electric vehicle battery is overused, it will cause excessive heating of the battery, which will cause the reduction of sulfuric acid in the battery and the reduction of the concentration, which will cause the production of a special substance, which is easy to be on the plate. A thick and hard crystal is formed on the surface, which will cause the battery's ability to accept electricity and reduce the battery's ability to use it.　　 8. Does the rated capacity of the battery have any relationship with the life? 　　 Yes. Battery capacity is affected by active materials and utilization. The external dimensions of the battery for electric mopeds have been fixed, and the quality of the plates has been limited to a certain extent. Only by increasing the utilization rate of active materials can the capacity be increased. To increase the battery capacity, it is necessary to increase the porosity, increase the content of PbO2 and the specific gravity of sulfuric acid, but these measures will accelerate the softening of the positive plate, resulting in accelerated degradation of battery life, and the active material will expand and contract during the charging and discharging process (especially the positive plate) , The deeper the discharge depth, the greater the expansion and contraction of the active material, and the faster the softening of the active material. Therefore, when the initial capacity is too large, it will directly affect the battery charge and discharge times. 9. When do we need to maintain and charge the battery? What should I pay attention to? 　　 When these situations occur: 1. The battery capacity becomes too small; 2. The battery is deteriorated and damaged; 3. The battery has lost liquid , After rehydration; 4. The battery is not used for a long time; 5. The battery is overused; 6. The battery is in a harsh environment for a long time; 7. The battery is under-charged for a long time, and maintenance and charging of the battery is required. The precautions are to charge under the voltage of the original charger, as well as multi-stage constant current charging. 10. Is battery performance related to temperature? 　　 High temperature, good charge acceptance, easy to charge and power; low temperature, it is difficult to charge and power, therefore, in our daily use, we must be careful not to cause the charger and The temperature of the battery changes too fast, which directly causes the charging performance of the battery and sometimes causes damage to the battery.　　 The above is the maintenance method of the electric vehicle battery, I hope it will be helpful to everyone! The battery allows you to go further! Prev: How to prevent the problem of electric vehicle charging and not turning lights
