Electric vehicles can already be said to be a necessary transportation tool for many people. The battery, as an important part of the electric vehicle, provides a strong power for the electric vehicle that is constantly running. Today, Xiaobian will tell you how to maintain the battery to make the battery life longer.
Does the newly purchased battery need to be replenished?
A: Yes, although the current electric vehicle batteries are made using the internalization process, but it is better to use and then charge, do not charge *** when used, the mileage will be relatively short, because the battery will have a self-discharge process when placed, so it is recommended to use after charging.
Do climate and temperature changes affect mileage?
A: Yes, discharge is a battery chemical process, the temperature is high, the reaction is fast, the capacity is large, and the capacity is small. If the electric vehicle is not used for a long time, how to place the battery?
A: The battery must be stored after sufficient power, and the battery must be supplemented once every 1-3 months to avoid the capacity reduction or even scrap of the battery due to long-term loss of power storage.
Will long-term short distance riding reduce capacity?
A: Yes, it is recommended to carry out a deep discharge every 2-3 months, discharge to undervoltage protection on a flat road, and the indicator is on, so that the battery can be activated and the capacity can be expanded.
Can the battery be disassembled and used?
| A: No, when the battery is delivered, according to the production date, batch number and process test result, the battery pack with similar performance is synthesized into the battery pack to achieve the best use effect. Moreover, the battery pack is randomly disassembled, and the batteries with different performance are mixed together, which directly affects the capacity and indirectly affects the service life.
Why does the battery bulge and deform?
A: The reasons for battery charging deformation are various, mainly the following points :1, the charger is unqualified or does not match, it is recommended to replace the charger.
2, its own quality problems, the battery production process acid added uneven or insufficient acid caused.
3, the charging current is too large or the charging time is too long, the temperature of the electrolyte rises, produces a lot of gas, and the active substance falls off, resulting in the battery charging and deformation. Does maintenance extend battery life?
A: For the lack of liquid, insufficient charge caused by sulfation, the correct maintenance can extend the battery life, take the addition of electrolyte, and then high pressure pulsation depolarization method, can make the battery capacity improved. However, the end of life caused by grid corrosion or softening of active substances or short circuit breakage cannot be restored by maintenance. If there is a battery problem, maintenance and testing should be carried out in time, and high-quality, reputable brand batteries should be selected when replacing the battery.
What should we pay attention to when carrying the charger?
A: Electric vehicles often vibrate due to uneven roads during use, and the charger will follow the vibration, and its component parameters will drift, affecting the charging performance and even damaging the battery. If you have to take it, the charger should be placed in a relatively elastic space.
What are the dangers of overcharging a battery?
A: If the use of inferior charger for charging, or the charger failure, or the battery charging time is too long, it will lead to battery water loss, premature drying of the electrolyte, easy to cause the deformation of the charging drum, so that the battery life is terminated in advance.
When is a better time to charge a battery?
A: When the overall power of the electric vehicle remains about 30%, it is a better time to charge the electric vehicle at this time, and the charging time should not exceed 12 hours to avoid overcharging the battery. If the daily cycling mileage is within 5-10km, it is recommended that you do not charge frequently, do not short mileage, frequent charging, otherwise it will cause early termination of battery life.
