Because
Used Car are driven by batteries and motors, they definitely need maintenance. Brake fluid still needs to be replaced normally, basically once a year or 20,000 kilometers, depending on the requirements of each manufacturer. Another thing that needs to be changed is the rear axle oil. Because Used Car are rear-wheel drive, they have a rear axle differential. The operation of the differential requires lubricating oil to ensure lubrication and cooling.
Basically, it is changed once a year, every 20,000 to 30,000 kilometers. If the rear axle oil is not replaced on time, it will cause serious wear of the gears in the differential, and over time, the differential will be damaged. Brake pads need to be inspected regularly and replaced if they are severely worn. Tires and other wearing parts also need to be inspected regularly.
1. Observe whether the charging time and charging capacity of the
Used Electric Car are significantly reduced.
2. Whether the pure electric cruising range is significantly reduced.
3. You can judge whether the Used
Electric Car needs to replace the battery through the after-sales service point. Use the OBD diagnostic instrument to conduct routine testing of the power battery, and perform repairs or computer data correction according to the errors prompted. By fully discharging the vehicle's power battery 1-2 times (discharge until the remaining power of the power battery is only about 5% of the critical value displayed on the instrument panel, and then fully charging it again), use professional instruments to record the data, and the data results A unified summary will be fed back to the manufacturer, and the manufacturer's technical staff will determine whether the battery replacement conditions are met. If the conditions are met, the battery factory will be approved to send a new battery to the dealer for replacement. If the conditions are not met, the corresponding solution will be fed back.
