How to choose an electric car, how to choose an electric car

1. When buying a car, consumers should look for the brands that have been approved by the relevant departments for production and the public security department can be licensed, and do not blindly purchase the unapproved brands, so as not to encounter trouble when the license is issued.

2. When choosing a car, you should look at the battery performance. The key to determining the quality of an e-bike is the quality of the motor and battery. The high-quality motor has low loss, high efficiency and long mileage. The battery is the key to the normal driving of the electric bicycle, and it is necessary to choose a brand battery with stable performance when buying a car.

3. Try to buy in large shopping malls, and identify reputable manufacturers and brands, and if possible, you can consult professionals to buy. After purchasing a car, you should ask the merchant for official invoices and after-sales service cards and other relevant vouchers, fully understand the product quality and service content promised by the manufacturer, and pay attention to whether the other party has a perfect after-sales service system.

4. Consumers should use electric bicycles in accordance with the instructions, avoid overloading and speeding, do a good job of maintenance, do not disassemble without authorization in case of failure, turn off the power when parking and leaving, and charge the car in time when the instrument shows insufficient power while driving, so that the car can drive in the state of sufficient battery power, so that the service life of the battery can be extended.

At least it is produced by a regular enterprise, so you can't deal with it when there is a problem. Dealers should not be too awesome, and some dealers are awesome and don't care whether consumers live or die.

How to buy an electric car is as follows:

1. Gross production qualification and 3C certification.

Before buying a car, consumers should first understand whether the manufacturer has production qualifications and 3C certification. After the introduction of the new national standard, enterprises are required to obtain production qualifications to produce products, and products must obtain 3C certification before they can be sold, and electric vehicles without 3C certification cannot be licensed and driven on the road.

2. Electric vehicle brand.

At present, the electric vehicle market is very broad, and there are many brands, so in this mixed market environment, choosing a big brand electric vehicle is the best for safety performance and after-sales. Consumers can compare and understand several more.

3. The performance of electric vehicles.

The main differences in the performance of electric vehicles are the battery, charger, motor, and controller. The capacity of the battery is related to the mileage of the electric vehicle, and the service life of the battery determines the driving cost of the electric vehicle. The motor is mainly related to speed, the faster the electric vehicle runs, the greater the power, the higher the **, and the new national standard requirements stipulate that the speed of the electric vehicle must reach 25km h.

Then choose a smart charger that can charge normally, or quickly. Finally, look at the controller of the electric car, the controller of the electric car plays the role of starting, running, advancing and retreating, speed, and parking, which is very important, and you must pay more attention to it before buying.

Summary. There are only a few brands of electric cars (1) Emma, Tianjin, and there are a lot of TV commercials. (2) Yadea, Jiangsu brand, is bombarded with TV commercials like Emma.

3) Xinri, which is also a Jiangsu brand, is stuffy to make electric vehicles, and there are not so many advertisements. (4) Luyuan, Zhejiang's brand, is also very good. (5) Mavericks, the main intelligent, new brand, the cooler ones on the road are basically Mavericks.

6) No. 9, the Xiaomi ecological chain, the No. 9 balance bike you should have heard of.

Hello, glad to answer for you. Here's how to do electric cars:

In the process of buying an electric car, the points that I pay more attention to are: [brand] [appearance] [battery] [tire] [brake].

Lead-acid is cheap, has high reliability, can be repaired by overcharging and overdischarging, and the performance attenuation is a little better in winter. However, the life is short, the calendar is relatively bulky and wide, and the cruising range is short under the same volume of limbs and pants. Lithium batteries are expensive, fast to charge, the same volume has a long battery life, and the life is also long.

However, at present, there are many lithium battery incidents, and the safety needs to be improved.

There are only a few brands of electric travel cars (1) Emma, Tianjin, and there are many TV commercials. (2) Yadea, Jiangsu brand, is bombarded with TV commercials like Emma. (3) Xinri, which is also Jiang Tan and Su brand, stuffy to make electric cars, there are not so many advertisements.

4) Green let the town focus on the source, Zhejiang's brand, also very good. (5) Mavericks, the main intelligent, new brand, the cooler ones on the road are basically Mavericks. 6) No. 9, the Xiaomi ecological chain, the No. 9 balance bike you should have heard of.

It is not recommended to buy an electric car on the platform, it is expensive and not necessarily good, buy it yourself, you can do UU errands without buying an electric car, but it is a little tight when you send something, you can take orders in UU errands and men's APP, if you do it for a long time, it is recommended to buy a two-wheeled tram.

Energy performance

1. Lead-acid batteries (lead-acid gel batteries) are cheap in cost and stable in performance, and most of the electric vehicles on the market use this kind of battery.

2. Lithium-ion batteries (often called lithium batteries) have high costs, but have the advantages of large specific energy, high specific power, small self-discharge, no memory effect, good cycle characteristics, wide operating temperature range, and no environmental pollution.

Although there are many types of vehicles, the structure is similar. This should be said to be the credit of standardization, but also the need for large-scale production lines. With the development of society, the progress of science and technology and the change of demand, the shape of railway vehicles has begun to change, especially the passenger car is no longer the same old face.

However, their basic structure has not changed significantly, but the specific parts have a more scientific and advanced structural design. Stuffy rules.

Generally speaking, the basic structure of the vehicle is composed of five parts: the car body, the undercarriage, the running part, the coupler buffer device and the braking device.

The body is the part of the vehicle that is used to load goods or passengers, and is the basis for the installation and connection of other components of the vehicle. In the early days, the body of the vehicle was mostly made of wood, supplemented by steel plates, bow rods, etc. In modern times, the car body is mainly steel structure or light metal structure.

1. First of all, brand first: well-known brands have a technical research and development team that is superior to other enterprises.

2. Dispatch and then personality models: unique electric vehicles can show a distinctive character.

3. Selected configuration: the deterioration of batteries, motors and other components directly affects the service life and subsequent consumption of electric vehicles.

4. Quality: Try to choose electric vehicles with low failure rate and low repair rate.

5. Sales: Large brand electric vehicles with high sales volume account for 30% of the total sales volume throughout the year.

6. Technology: The mountainous plains are like walking on flat ground, and the motor power is indispensable.

7. Final speed: Large brands are speeding up both in Liang Xiansou's brand image and the terminal market.
