How to maintain electric vehicles

With the development of technology, there are more and more types of electric vehicles in the market. Because of the energy saving and environmental protection, many car owners have chosen electric vehicles. So maintenance problems electric vehicles are increasingly being recognized, the North following mai mai North Auto Parts Network Xiaobian to explain ensure the conservation knowledge of electric vehicles, electric vehicles exactly how to keep insurance, read the following article below You will understand.

First, battery maintenance

1. Correctly grasp the charging time and frequency of the battery

Everyone applies different situations to the car. Therefore, charging should be carried out according to your actual situation. Don't be too confident that others will charge for a few hours. Regarding how long it takes to charge a single charge, it is also necessary to make a decision based on its mileage. In the case of normal driving, if the red and yellow lights of the indicator of the electricity meter are on, it should be charged; if the yellow light is off, only the red light is on, stop charging as soon as possible, otherwise the battery will be due to Over-discharge and shorten life. Some people are used to charging each time before leaving home, sometimes only after a very short period of time to recharge, this time charging time is not too long, or it will overcharge and make the battery heat. Generally speaking, the average charging time of the vehicle battery is about 10 hours. Overcharging, over-discharging and insufficient charging will shorten the life of the battery. If the battery temperature exceeds 65 °C during charging, stop charging immediately.

2. In the process of opening the line, you should avoid the slamming speed as much as possible.

When the electric car starts, manned, or goes uphill, if it is stepped on the speed, it will form a large electric discharge. The large electric discharge is easy to cause the formation of lead sulfate crystals, thereby damaging the physical function of the battery plates. If the speed of the vehicle suddenly drops by tens of kilometers during driving, you must be careful that perhaps a certain battery has a problem and should be detected as soon as possible.

3. It is strictly forbidden to expose electric vehicles to the sun.

A battery that has been exposed to sunlight will lose water due to an increase in internal pressure, causing a decrease in battery activity and aging of the plate.

Second, tire maintenance

The types of electric vehicle tires can be divided into inflatable tires and solid tires according to different carcass structures. Most of the modern electric vehicles use pneumatic tires. Inflatable tires are classified into three types: high pressure tire (0.5-0.7Mpa), low pressure tire (0.15-0.45Mpa) and ultra low pressure tire (0.15Mpa or less) according to the air pressure inside the tire. The low-pressure tire has good elasticity, wide section, large grounding area, and good thin wall heat dissipation, which is beneficial to improve the ride smoothness and stability of the electric vehicle, and can also improve the application life of the tire. Therefore, the low-pressure tire is generally applied to the electric vehicle.

In the safety situation of vehicles, tires are essential. In order to avoid the power consumption caused by incorrect tire pressure, shorten the life of tires, puncture and other conditions, which affect the comfort and safety of driving, Xiaoyi reminds you that electric vehicles are mainly Tire pressure is often detected and the tire pressure is checked in two weeks or one month.

Third, the cleaning of electric vehicles

The clarity of the electric vehicle can be in accordance with the cleaning method of the conventional vehicle. However, during the cleaning period, it is particularly necessary to avoid the water flowing into the charging socket of the vehicle body, causing the vehicle body line to be short-circuited. Care should be taken when cleaning the power battery. Do not use water jet cleaning to avoid the battery being short-circuited by moisture.

Fourth, the remaining important matters needing attention

1. The battery can't be charged. When repairing the charging part or replacing the charging fuse, be sure to unplug the 220V power plug first; always turn off the power switch every time you park, pull out the key, and move the gear switch to the neutral position, and Pull up the handbrake;

2. Repair or replace the battery and electric appliance after closing the main switch of the power supply;

3, when charging should be avoided as far as possible to expose children, as far as possible in places where children have no access;

4. The main power switch should be closed immediately when a fire occurs due to an accident or other causes.

5. Because vehicles equipped with lithium batteries are more prone to fires, it is forbidden to drive dangerously. The dangerous driving situation of electric vehicles is also very serious.

Through the introduction of Xiaobian, do you have a deeper understanding of how to maintain electric vehicles? If you plan to buy electric vehicles, you must first understand their maintenance knowledge. Only in this way can you properly operate electric vehicles to prevent damage. Great security risks. Make yourself safer to travel.

Mooring Rope include polyamide fiber series, polyester, resin series, UHMWPE, etc. The products in terms of structure include 3-ply, 4-ply, 6-ply, 8-ply, 12-plyand 48-ply (double-layer braided) with the diameters ranging between 4mm and 146mm for your option. All mooring ropes have wide range of application with the high strength, low elongation, wearing resistance and anti-corrosion.They are soft, smooth and easy for operation. Meanwhile.

Mooring rope is mainly used in fields of ships and vessels, fishing, loadong and unloading in harbor, power supply construction, petroleum survey, physical exercise wares, antional defense scientific and research etc.
