The post maintenance of extended range new energy vehicles mainly includes the following aspects:
1. Battery system maintenance: Regularly check the health status of the battery pack, including charging status, battery capacity, and battery temperature, to ensure that the battery is in optimal working condition. Clean the battery pack cover and column liquid level to avoid dust coverage, strengthen the sealing of the tray and battery cover, and maintain battery stability. Follow the manufacturer's guidelines for proper charging and discharging operations to avoid excessive discharge or prolonged high battery life, in order to extend the battery's lifespan. Check the battery connection to avoid corrosion and looseness, pay attention to battery insulation requirements, and maintain stable current.
2. Maintenance of power and transmission system: Extended range electric vehicles combine internal combustion engines and electric drive systems, so consumables such as oil and filters need to be replaced according to the manufacturer's recommended cycle. Check the lubrication and wear condition of drive system components such as transmission shaft and reducer to ensure the normal operation of the transmission system. For the internal combustion engine, although it operates less frequently than traditional fuel vehicles, regular maintenance is still crucial to ensure performance and stability.
3. Inspection and maintenance of other key systems: Braking system: Regularly evaluate the wear condition of brake pads, check the level and quality of brake fluid, and ensure the safety and effectiveness of the braking system. Tire and suspension system: Monitor tire pressure and wear, perform necessary tire rotation and balance adjustments; Check the condition of suspension system components such as shock absorbers, springs, etc. to ensure their normal operation. Air conditioning system: Regularly replace the air conditioning filter to ensure the air quality and efficiency inside the car. Electrical system: The electrical system, including car lights, turn signals, and horns, needs to be regularly inspected to confirm that their various functions are functioning properly. Appearance maintenance: Regularly repair damaged car paint to maintain the appearance of the car body; Clean the vehicle with neutral car wash agent to protect the paint surface; Check the wiper rubber strip and replace it if necessary; Check the function of the car lights to ensure driving safety. Chassis maintenance: Regularly inspect and maintain the chassis to ensure stability and safety.
The post maintenance of extended range new energy vehicles requires comprehensive consideration of multiple aspects such as battery system, power and transmission system, braking system, tire and suspension system, air conditioning system, electrical system, appearance, and chassis to ensure the performance, safety, and service life of the vehicle. It is recommended that car owners strictly follow the maintenance manual and recommendations provided by the manufacturer, and choose reputable professional car repair and maintenance institutions for regular maintenance.
