What to pay attention to when buying electric cars

1. Choose a brand. Generally speaking, brand-name products have a long operating history and have formed a mature quality control system in development and design, parts configuration, production process, after-sales service, etc., with stable and reliable quality, high credibility, and guaranteed after-sales service.

2. Choose service. When buying an electric car, you must pay attention to whether the product has after-sales service points in the area, how far it is from your work and life, and its reputation in terms of service quality and credibility.

3. Choose a car model. Currently, electric cars are generally divided into two types: luxury and lightweight. Consumers should choose a suitable car model based on their own needs, rather than blindly pursuing appearance.

4. Choose the configuration. Whether an electric car is durable, safe and economical is closely related to its four major components. Therefore, consumers must carefully select its configuration when purchasing.

5. Battery. As the "heart" of electric vehicles, batteries are the "heart" of electric vehicles. Consumers must be cautious when purchasing them, because the quality of batteries also directly affects the operation of other "organs" such as motors, chargers, and controllers: First, it depends on whether the battery manufacturer is strong and whether the product is reliable; secondly, pay attention to the service life of the battery.

6. Charger. The quality of the indispensable Greenleaf charger is directly related to the life of the battery. Some inferior chargers may even cause the battery to deform. When choosing a charger, be sure to choose a charger from a regular manufacturer, and make sure the manufacturer of the charger is the same as the manufacturer of the battery, so that even if a fault occurs, you can find the corresponding manufacturer to repair or exchange it.

7. Motors and controllers. The backbone of electric vehicles According to some industry insiders, motors are the key to starting and accelerating electric vehicles, and the efficiency of motors will directly affect the life of batteries. As the "organ" that assists electric vehicles in stepless speed regulation, brake power-off, soft start and other functions, if the controller is not designed properly and the current limit is too large, it will also seriously affect the life of batteries and motors.

What is the lifespan of an electric car battery?

1. As far as the current situation is concerned, the battery determines the life of electric vehicles. The life of fuel cars can be more than 15 years, and the structure of electric vehicles is simpler than that of fuel cars. The life of the internal combustion engine of fuel cars is a key factor affecting the life of cars. In my country, as long as private cars can pass the inspection (up to four times a year), there is no limit on the age of scrapping private cars. The reason for failing the annual inspection is mostly due to unqualified emissions and failure to meet the standards. Emissions are mostly caused by factors such as the engine.

2. Electric vehicles are developed from fuel vehicles, but they use motor batteries to replace internal combustion engines. The lifespan of other components of electric vehicles is almost the same as that of fuel vehicles, so the main consideration is the battery life. The lifespan of motor controllers and other components is basically not considered, as the technology is very mature. The battery life restricts the lifespan of electric vehicles.

3. From the publicity of a certain manufacturer, it can be seen that the capacity decay of the battery within 30% after about eight years of use is normal. Ternary lithium batteries are adopted by more and more manufacturers because of their high power density, good low-temperature discharge characteristics, and high-power charge and discharge. Even BYD has begun to switch to ternary lithium batteries, but the capacity decay of lithium batteries is an unavoidable problem. The life span can be used for eight years, but after eight years, the capacity decay is not good, so the life span of ordinary pure electric vehicles is about eight years.

Why do pure electric vehicles use lithium batteries?

Although lithium batteries are more expensive, they are lighter, have a longer charge and discharge life, are easier to maintain, and are more convenient for later vehicle maintenance. Therefore, pure electric vehicles generally use lithium batteries.

As of August 2019, there are two types of lithium batteries on the market: lithium metal batteries and lithium-ion batteries.

1. Lithium metal battery:

Lithium metal batteries generally use manganese dioxide as the positive electrode material and metallic lithium or lithium alloy metal as the negative electrode material. This type of battery uses a non-aqueous electrolyte solution.

2. Lithium-ion battery:

Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material and graphite as the negative electrode material. This type of battery uses a non-aqueous electrolyte solution.

Things to note about car batteries:

1. Check the car's power on time to avoid unnecessary trouble caused by low battery while driving.

2. When the car is not used for a long time, start it once on time to ensure that the battery and various oils in the engine can work normally.

3. When replacing a car battery, it is best to replace the original battery, which is guaranteed in quality and will not create any safety hazards.
