Maintenance content of electric vehicle

Maintenance contents of electric vehicles: appearance inspection, engine room inspection, chassis inspection, replacement of gear oil and brake oil & antifreeze.

1, visual inspection.

The appearance inspection is similar to that of a fuel car, including the body, headlights, tire pressure and so on. Electric vehicles also need to check the charging socket to see whether the plug of the charging socket is loose and whether the contact surface of the rubber ring is damaged by oxidation.

If the socket is oxidized, it will lead to the plug heating. If the plug is heated for too long, it will cause short circuit or poor contact, which will damage the charging gun and the car charger.

2. Engine room inspection.

There are many electric vehicle lines, so it is necessary to check some socket connectors and line insulation protection.

3. Chassis inspection.

The power batteries of electric vehicles are basically arranged in the vehicle chassis, so the power battery guards, suspension parts, axle sealing sleeves, etc. Maintenance, fastening and inspection will be carried out during maintenance.

4. Change gear oil.

Most electric vehicles are equipped with single-speed gearboxes, so it is necessary to change gear oil to ensure the normal lubrication of gear sets and drive motors at work. There is a saying that electric vehicles need to change gear oil regularly, and there is also a saying that vehicles need to be replaced only after driving for a certain mileage. I think this has a lot to do with the specific model.

After cleaning the old gear oil, add new oil. The gear oil of electric vehicles is not much different from that of traditional fuel vehicles.

5. Brake oil and antifreeze.

Because the electric car has no engine, it does not involve oil and machine filter. Attention should be paid to brake oil and antifreeze. If there is no leakage, brake oil and antifreeze can be replaced according to the cycle specified by the manufacturer, which is not much different from that of fuel vehicles.

How to use electric vehicles safely;

First, we should attach importance to product quality and resolutely avoid unqualified products. It is necessary to purchase qualified products through formal channels, and resolutely do not modify or disassemble electric bicycles privately.

Second, we should pay attention to the location of charging and resolutely avoid sharing rooms with people and cars. Don't charge in corridors, hallways and other indoor public areas, and don't park indoors to charge. In the event of a fire, hot toxic smoke is likely to cause casualties.

Third, pay attention to the charging time and resolutely avoid long-term charging. Because a large part of electric bicycles have no overcharge protection function, it is very easy to lead to the high temperature of the battery after the battery is fully charged, and such high temperature can also easily lead to fire accidents.

Fourth, we should pay attention to the charging method and resolutely avoid flying wire charging. Charge on a fixed charging facility, and don't pull wires to charge.
