The routine maintenance of new energy vehicles includes three-electric maintenance, chassis inspection, lighting inspection, tire and brake inspection.
1. Three-electric maintenance
Three-electric maintenance inspection is the focus of new energy vehicle maintenance, although it is only the main parameters of the computer once, but its vital importance is much higher than other conventional testing items. The power system consists of three parts: the power battery, the motor and the speed control system, which correspond to the fuel supply system, engine and transmission of the fuel vehicle.
Needless to say, check the status of each information of the battery pack to avoid spontaneous combustion caused by overheating of individual battery charging and discharging, and the speed regulation of the motor is to adjust the input voltage through the ECU.
2. Chassis inspection
Weekday travel, the chassis is always the closest to the roadside, there are often all kinds of complex road conditions on the road, which is likely to cause a certain scratch on the vehicle chassis, and it is natural that the market must test new energy vehicles. The inspection includes whether the transmission parts and suspension parts are loose or damaged, and the chassis corrosion detection.
3. Lighting inspection
The lighting inspection of new energy vehicles must not be ignored, whether it is driving during the day or at night, headlights, tail lights, brake lights, turn signals, warning lights, fog lights, etc. Lights not lit may cause safety hazards, although fog lamps are rarely used, but often used when running long distances, of course, don't forget to check whether the front and rear fog lights can work properly.
4. Tire and brake inspection
In addition to the detection of the three-electric system of new energy vehicles, it is also necessary to test the brake pads, tires and wipers and other commonly used wearing parts of new energy vehicles. For example, check whether the tire pressure is normal, whether the brake pads are aging, etc.
