As new energy vehicle technology continues to mature, new energy vehicles have been welcomed by the general public and have gradually integrated into our lives. There are more and more green license plates on the road. In the process of our use, there will always be many problems and questions. Today, the editor will introduce you to some common sense about new energy vehicles.
No. 1: What is a new energy vehicle?
New energy vehicles refer to vehicles that use unconventional vehicle fuels (or conventional vehicle fuels and new vehicle power devices) as power sources, integrate advanced vehicle power control and drive technologies, and have advanced technical principles, new technologies and new structures. . New energy vehicles include extended range electric vehicles, hydrogen engine vehicles, fuel cell electric vehicles, pure electric vehicles and hybrid electric vehicles.
No. 2: What are the advantages of new energy vehicles compared with traditional vehicles?
1. Advantages: energy saving and emission reduction
Energy saving: Traditional fuel vehicles only convert 17%-21% of the energy stored in the fuel into power for the wheels, while electric vehicles can convert 59%-62% of the electricity from the grid into kinetic energy for the wheels. Emission reduction: Traditional fuel vehicles produce a large amount of harmful gases, such as hydrocarbons, carbon monoxide, nitrogen oxides, etc. , will be directly discharged into the air, causing serious pollution and damage to the ecological environment. However, electric cars have no such problem.
2. Advantages: more comfortable
Electric cars start, drive and stop more smoothly and accelerate faster than traditional cars. There is no roar of a fuel engine and the noise is lower.
No. 3: How to ensure the correct charging method of electric vehicles?
When charging, observe frequent charging and shallow charging to understand the charging time and frequency of the vehicle. Keep the battery fully charged until the battery capacity drops below 15% to 20% before charging again. Excessive discharge will cause the positive active material and negative active material inside the battery to gradually transform into resistance, thereby reducing the service life of the battery. In daily use, if the current remaining power cannot meet the subsequent destination mileage, you must find a nearby charging pile to charge. If you have plenty of time, give priority to the slow charging mode; moreover, pay attention to the weekend environment and battery temperature when charging. For example, when charging outdoors in the cold season, it is not recommended to do fast charging under extreme conditions. You can use slow charging first to keep the battery in good condition, and then use fast charging.
No. 4: What are the daily maintenance items for electric vehicles?
Electric vehicles require maintenance just like traditional vehicles, but the maintenance items are different. If owners of fuel-powered vehicles maintain the engine system and transmission system, they must regularly replace the engine oil, engine filter, air filter, and steam filter. Electric vehicles rely on batteries to provide energy and motors to drive.
Routine maintenance items such as engine oil and "three filters" are naturally omitted. Only the battery pack and motor require maintenance to keep them clean. Engine room: Engine room inspection must be carried out by professionals. Before opening the engine room, protective measures should be taken. During maintenance, check whether the cabin wiring harness is aged or has false connections, etc. Remember, due to the special nature of new energy vehicles, water is not allowed to clean the cabin.
Battery: As the power source of new energy vehicles, battery is one of the most important components. Inspections and maintenance should be carried out regularly at a repair shop. Or improper daily use may cause battery loss.
Antifreeze: Unlike fuel vehicles, the antifreeze of electric vehicles is used to cool the motor and needs to be replaced regularly according to the time specified by the manufacturer.
