Analysis of electric vehicle battery maintenance

The battery of an electric vehicle needs to be replaced after a year or a half load. How can you extend the battery life of an electric vehicle? (1) The first thing is not to be overloaded or overloaded (such as riding a bicycle with people or loading heavy objects). When the flashing power on the surface is lacking, it is necessary to use manpower to ride, because deep discharge consumes a lot of battery life. (2) Pay attention to the charging method. When the new battery is charged for the first time, the time must be long to ensure that the power is satisfied. Regarding the lead-acid battery, no matter how far you travel, you must charge it immediately after using it. Don’t charge it until the battery is completely exhausted. If the car captain doesn’t use it all the time, make sure to recharge it once a month. This can not only protect the battery, but also extend its service life. (3) Beware of sudden braking as much as possible. Repeated sudden braking will affect braking flexibility and consume battery capacity; the vehicle speed should not be too fast. The faster the vehicle speed, the greater the loss of the battery. (4) Don't use the motor to propose the car straight when it is stopped, it is best to use the foot to assist the proposal. When going on the bridge, uphill, or headwind, you must use the foot pedal to help prevent impact damage to the battery, affecting the battery's continued travel and service life. (5) Maintenance of electric vehicle battery during operation a) When starting, going on a bridge, climbing, or driving against the wind, manpower should be supplemented to guard against instantaneous high current discharge as much as possible. b) When you need to accelerate, you should slowly rotate the speed control handle, and be alert to accelerate straight to the fastest gear. c) When the road conditions permit, the electric vehicle can be driven at the highest speed as far as possible. d) Try to guard against repeated brakes and suggestions, and use pedals to drive when the journey is congested. e) The power flashes. The battery is dead. After a while, you will find that the battery has a small amount of voltage, called the rising voltage. The user should be wary of using this rising voltage to ride. (6) In terms of charging, maintenance of electric vehicle batteries a) Charge at night, the average time is about 8 hours, guard against overcharge and undercharge. b) When charging, when the indicator light flashes, do not unplug it immediately when it is fully charged, and then float it for 2-3 hours. c) Try to spread the electricity all at once. If you really want to ride during the charging process, it should be full immediately after riding. d) Frequent charging is beneficial to the cycle life, but many chargers currently in circulation on the market have high defect rates, poor reliability, and low accuracy. Therefore, sometimes charging frequently affects the service life of the battery. When the battery is discharged and recharged, it may constitute over-discharge of certain cells. The charge acceptance of over-discharged batteries will be greatly reduced, causing problems with lack of charging. Others, because the recharging after discharged, the charger will be overloaded for a long time, and the charger will be easily damaged. . Therefore, it is more reasonable to charge once when the battery discharges 50-70% of the power, which has advantages on the battery life. (7) The maintenance of electric vehicle battery should pay attention to the lack of electricity storage. The lack of electricity means that the battery is not charged in time after use. Sulfation occurs in the state of power deficit, and lead sulfate crystals are attached to the electrode plates, blocking the ion channels, causing a decrease in battery capacity. The longer the power-loss condition is left, the more severe the battery damage. Especially in summer, it must be charged in time. The storage time will be compensated for every month. (8) The maintenance of electric vehicle batteries should also be protected in time. When the battery presents the following conditions, it is necessary to protect a) Long-term charging does not change the green light b) The battery is hot while charging c) The battery capacity drops too fast (9) The maintenance of electric vehicle batteries Punctual inspection During the application process, assuming that the continued journey of the electric vehicle suddenly drops more than ten kilometers in a short period of time, it is very likely that the rarest battery in the battery pack is broken, the plate is softened, and the plate's active material is dropped. Short-circuit phenomenon such as drop. At this time, inspection, regeneration and assembly should be carried out in time. In this way, the battery pack life span can be relatively extended and expenses can be saved to the greatest extent. (10) Pay attention to the maintenance of the electric bicycle battery: the battery should be installed on the electric bicycle to prevent the battery from being damaged by vibration when riding; often remove the dust and dirt on the battery cover, and pay attention to the monotony and cleanness of the battery. To prevent the battery from discharging by itself. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
