Electric vehicle is one of the necessary means of transportation for many office workers to travel in winter, but in winter, many people will reflect that electric vehicle is easy to break down and the battery is not durable. Ms. Zhang said that recently, she found that the battery power of electric vehicles is not as durable as in summer, and she often "strikes" on the way, which she has encountered many times. In fact, when the temperature drops in winter, the battery storage capacity of electric vehicles will be affected, and problems such as power reduction or poor charging will often occur, as well as the speed and riding mileage of electric vehicles.
Therefore, the correct use and timely maintenance of electric vehicle battery is particularly important in winter. So, how to charge electric vehicles correctly in winter? Please remember the following 10 tips:
1、 Increase the charging times when using electric vehicles, do not recharge the batteries when they do not have any power. The battery life of electric vehicle will be affected if the battery is in the state of insufficient power for a long time. When the battery has the remaining power, it should be charged. Don't overuse or charge frequently. After using the electric vehicle, do not just use a little electricity to charge the battery, which is easy to cause damage to the battery and reduce the service life. It is recommended to charge when the power is about 30%. In winter, never let the battery be in a state of insufficient power for a long time. You must form the habit of timely charging at night no matter how many trips you make every day. But when the electric vehicle battery is charged, we must pay attention to the time, do not overcharge the battery, overcharge will cause damage to the battery, damage the battery capacity, and reduce the battery life.
2、 When charging in sequence, plug in the battery first and then the power plug. After charging, unplug the power plug and then the battery plug.
3、 During the initial start-up of the electric vehicle in the cold winter, the foot pedal must be used for daily maintenance, and the "zero start" must not be allowed to avoid a large amount of current discharge, otherwise the battery will be greatly damaged. The temperature is relatively low in winter, which affects the battery power. In winter, when riding an electric vehicle on a large slope, you should use foot pedal to help reduce the power consumption. When going downhill, you can turn off the power, which saves power and prevents unintentional rotation acceleration from causing accidents. When not using electric vehicles, pay attention to keeping the battery warm. When not using electric vehicles in winter, it is better to take the electric vehicle battery indoors to prevent the outdoor low temperature from causing damage to the electric vehicle battery.
4、 Storage of battery in winter if the vehicle is parked in the open air or cold storage for several weeks without use, the battery shall be removed and stored in a warm room to prevent the battery from icing damage, and never be stored in a state of power loss. If it is not used for a long time, it shall be charged once a month.
5、 It is also important to clean the terminals of the battery and apply special grease to protect them, which can ensure the reliability and prolong the life of the battery when the electric vehicle starts.
6、 When equipped with a special charger, a matching special charger shall be used. Due to the different battery formula and process, the technical requirements for chargers are also different. Which kind of charger can be charged with which brand of battery can be charged, which are different. Therefore, do not mix chargers.
7、 Floating charge benefits: after the indicator light changes to indicate full charge, the charger should continue floating charge for 1-2 hours as much as possible, which is also good for inhibiting battery vulcanization.
8、 Do not overcharge the battery of electric vehicle. Do not overcharge the battery. Overcharge will cause damage to the battery. If the electric vehicle battery does not stop for a long time after being fully charged, the charging current will be continuously input into the battery, the voltage will continue to rise, the result of the voltage rise will intensify the thermal reaction of the electrolyte, the battery shell will be deformed (expanded) if it is light, and the battery will be charged if it is heavy. SUPERWAY battery, the leading brand of electric vehicle battery, reminds consumers: don't worry too much about the use of battery in winter, the power of electric vehicle battery will recover naturally with the temperature rising. Generally speaking, in the winter when the temperature is too low, shorten the use time of the electric vehicle as far as possible, and charge in time can effectively extend the service life of the battery.
9、 When riding an electric vehicle in winter, pay special attention to check whether the tire pressure is sufficient, whether the front and rear brakes are sensitive, whether the vehicle makes abnormal noise, whether the screw is loose, and whether the battery is fully charged before going out; When cycling, keep a high concentration of attention. Don't carry too many and heavy objects on the car body. The tire air should not be too full. It's better to put the air to 2 / 3 of the normal inflation volume. Increasing the contact area between the wheel and the ground can prevent slipping.
10、 Lower the center of gravity, try to avoid the sudden brake to lower the seat and lower the center of gravity; keep a distance of more than 3 meters from the vehicle in front to prevent the vehicle in front from slipping and tripping itself; do not slam the brake, otherwise the wheel will slip and lose balance, and you can ride slowly and get off early in case of any situation; try to avoid sharp turns, and the larger the turning radius is, the safer it is; Do not rush to the road with the motor vehicle to prevent it from being damaged by the side sliding motor vehicle; when encountering the snow ground and uneven ice surface, it is better to get off the vehicle and push it.
