How to maintain new energy vehicles?

The maintenance and maintenance of new energy vehicles mainly include the following four aspects: First, the maintenance of the appearance. Like fuel vehicles, the maintenance of electric vehicles requires visual inspection first, including damage to the paint and whether the lights are functioning normally. In addition, the aging degree of the wiper and other components and the condition of the tires are all points to be paid attention to. Of course, these are relatively conventional things, and car owners will pay attention to them when they use the car daily, and there is no need to drive to the 4S shop. The second is the maintenance of the chassis. In the description of the spontaneous combustion accident of the NIO vehicle, it was mentioned that the chassis of the vehicle had been severely hit before being sent for repair, which caused a large-area deformation of the left rear shell and the cooling plate of the power lithium-ion battery pack. The internal structure of the battery pack formed a short circuit after a period of time under the squeezed state, which eventually caused a fire. Here we don’t have to worry about why the chassis has experienced a serious impact and has not issued a warning, and we focus on the importance of chassis maintenance. As the closest component to the road, the chassis is inevitably scratched during driving, so it is necessary to conduct a comprehensive inspection during maintenance. The inspection contents include whether the transmission components, suspension parts are loose or damaged, and whether the chassis is corroded, etc. Regarding the maintenance of the chassis, it is important to check, and if a problem is found, repair it in time. Third, check the oil level. Although a pure electric vehicle does not have an engine, its battery and motor must be filled with coolant to cool and dissipate heat. In addition to checking the coolant level during maintenance, a freezing point test must also be performed, especially when the winter is about to enter. Before maintenance. In addition, pay attention to the inspection and replacement of brake fluid and glass water. This is the same for pure electric vehicles and fuel vehicles. Fourth, the inspection of the power system. Whether it is a fuel vehicle or a pure electric vehicle, the inspection of the power system is very important, and some safety hazards can be eliminated through the inspection of the power system. Regarding the three-electric system of pure electric vehicles, the maintenance master will usually take out a laptop to connect the vehicle data line to do an all-round inspection of the vehicle. Including the condition of the battery pack, battery voltage, SOC power, battery temperature, CAN bus communication status, etc., there is basically no need to replace wearing parts.
