Is there a difference between new energy vehicle maintenance and fuel vehicle maintenance?
The difference between pure electric vehicles and fuel vehicles lies in the difference of power systems, so traditional vehicles do not need to maintain engines, such as oil, "three filters" and spark plugs.
Pure electric vehicles mainly carry out daily maintenance on battery packs and motors, and generally focus on checking and troubleshooting.
Of course, other projects, such as the inspection and maintenance of brake system, cooling system and shock absorption system, and pure electric vehicles also need regular maintenance. However, the replacement cycle of these projects is long, mainly based on daily inspection.
1. Appearance inspection:
First of all, the maintenance of electric vehicles should be visually inspected, including the damage of car paint and the normal function of headlights, the aging degree of wipers and other components, and the inspection of tires.
2. Replacement of air filter:
In terms of air conditioning system, there is not much difference between pure electric vehicles and fuel vehicles, so it is necessary to check the air conditioning filter and other components during maintenance and replace them as appropriate.
3. Check the oil level:
Although the pure electric vehicle has no engine, its battery and motor also need to be cooled by adding coolant. In maintenance, besides checking the liquid level of coolant, freezing point test is also needed, especially before winter. Attention should also be paid to the inspection and replacement of brake fluid and glass water during maintenance. Pure electric vehicles are the same as fuel vehicles.
4. Power system inspection:
The inspection process of power system is similar to that of fuel vehicle. Only through the power supply system can we know where it needs to be replaced, but the inspection of electric vehicles may be a little more complicated, and it is necessary to check some socket connectors and line insulation protection.
5. Inspection of battery system:
As an important part of electric vehicle, battery is also an important process of electric vehicle maintenance. Usually, 4S stores have professional instruments that can accurately check the state of batteries.
6. Chassis inspection:
Chassis inspection is to check whether there are scratches on the chassis, whether the depth of the scratches will involve water ingress in the chassis and whether there is water leakage in the chassis. Check the wiring of the chassis and check the wiring harness for damage or aging. Check the degree of tire wear, whether the tire pressure is normal and whether the brake pads need to be replaced.
Extended data:
How long is the maintenance cycle of new energy vehicles?
The maintenance of pure electric vehicles is relatively simple. Generally speaking, the first maintenance is carried out around 5,000 kilometers, and then every 65,438+00,000 kilometers, with slight differences between different models.
The maintenance cycle of hybrid vehicles is basically the same as that of fuel vehicles, generally 5000~ 10000 km or half a year to one year, for routine maintenance.
