Since the epidemic prevention and control has opened the “home” mode, many car users in Shanghai and other places recently expressed their exclamation “when was the last time I drove out?”.
People depend on food and cars on electricity. Experts from a number of car companies and relevant institutions, including listed companies of new energy vehicles, told the Shanghai Securities News that for a long time of isolation, we must pay attention to vehicle maintenance, remind car users to carry out vehicle maintenance according to the “list” during the epidemic, pay attention to prevent accidents and be responsible for the safety of themselves and others.
electric vehicle battery power remains about 80%
“It is recommended to keep the power battery at about 80% before parking the electric vehicle.” According to the relevant person of Weima automobile, electric vehicles should not be parked in low-lying areas to avoid flooding of vehicles in rainy days, nor should they be parked under trees or places at risk of falling objects, so as to prevent vehicles from being eroded or damaged by foreign objects; When the vehicle is parked, confirm that the hand brake has been pulled, the window and skylight have been closed and the door has been locked.
If the vehicle is parked for a long time, every 3 days, the qualified electric vehicle can remotely ventilate the window and turn on the air conditioner to ventilate the vehicle.
Weilai automobile technicians said that users need to pay attention to the remaining power of the power battery. It is recommended that qualified users charge the vehicle when the power of the electric vehicle is less than 10%; The person concerned pointed out that in order to maintain vehicle communication, pure electric vehicles and increased electric vehicles will consume the power of small batteries. The large batteries of pure electric vehicles and increased electric vehicles will charge small batteries. However, if the parking time is relatively long, it is recommended to start the vehicle regularly Saic Motor Corporation Limited(600104) technicians also introduced that many electric vehicles are now equipped with vehicle machine system. Even if the electric vehicle stops driving, the background is working and sending signals. Small 12V batteries will cost more electricity. Users need to pay attention to prevent power loss.
For fuel vehicles, tuhu car maintenance technicians suggest that during a long time at home, fuel vehicle users should also remove the negative terminal of the fuel vehicle battery, cut off the power of the whole vehicle, and then lock the door with a mechanical key. When you need to use the car, reinstall the power cord and set the clock and stereo. In addition, it should be noted that the vehicle oil has a shelf life, and pay attention to the oil inspection of the whole vehicle, including engine oil, brake oil, steering oil, etc. Once the oil warranty period has passed, the vehicle still has potential safety hazards.
In addition, when the fuel vehicle is parked and dormant for a long time, it will also consume the power of the battery and even lose power, which will not only make it difficult or even impossible to start the vehicle, but also reduce the service life of the battery. Therefore, when the vehicle is turned off, you need to remember to turn off all electrical appliances, such as air conditioning, lights, etc. If the parking time is long, you can start the vehicle regularly in about 5-7 days without driving. Keep the engine speed above 1200 rpm for at least 10 minutes, and automatically charge the battery to keep the battery full.
people make nucleic acid and cars need disinfection
Professor Pu Weida, an expert in the automotive industry, said that during the epidemic, not only people should do a good job in protection, but also nucleic acid testing when necessary, but also vehicles should be disinfected and sterilized. It is recommended to carry disposable disinfection paper towels with you, clean and disinfect your hands before getting on the bus, and wipe the four door handles, trunk switches and car keys to reduce the possibility of artificially bringing viruses into the car.
After entering the vehicle, it is also recommended to use disposable wipes or use 84 disinfectant, disinfected disinfectant and disinfecting foam according to the operation requirements, and cautiously use 75 degree alcohol. Focus on wiping the high-frequency contact parts such as seat and safety belt, steering wheel, gear handle, one key start, central control, instrument panel and screen, handle and handbrake.
Puweida pointed out that after the wiping, the door should be opened and ventilated for a period of time to eliminate the residual smell of disinfectant, reduce the alcohol concentration, ensure safety, and prevent ignition and explosion caused by too high alcohol concentration in the car cabin. In addition, do not store 75 degree alcohol in the car, because the temperature rise is easy to cause problems such as burst, leakage and ignition.
Puvida also suggested that in densely populated areas, turning on the internal circulation of vehicle air conditioning can prevent the invasion of external polluted air. However, the filtering accuracy of vehicles with pollen filtering function can not meet the requirements of virus filtering. The size of pollen and dust is much larger than that of virus. It is recommended to wear a mask when driving. In addition, the air filter element is like a “Mask” of an automobile. Generally, the replacement cycle of the air filter element is 10000 kilometers. If it has not been replaced for a long time, it needs to be considered to replace it. Without replacement for a long time, the air filter element absorbs a lot of dust, bacteria and viruses, which is difficult to achieve the effect of filtration and cleaning.
