How to choose a good electric car

How to distinguish between good and bad when buying electric bicycles is a headache for many consumers. The following is my collection for you to choose a good electric car. I hope it helps you! Welcome to read the reference study!

How to choose a good electric car charger?

First, brand choice.

Some people say that electric bicycles have three points of quality and seven points of service, which makes sense. Brands with good quality but no after-sales service will also bring great trouble. Well-known brands have gone through a certain degree of market experience, and have strict control systems in technology research and development and after-sales service, which is trustworthy. Therefore, brand electric vehicles are an insurance choice.

Second, internal quality.

The quality and adaptability of these four parts are very important to improve the performance of the whole electric bicycle. The specific car can look at these four blocks first.

Generally speaking, the faster the speed, the greater the power, the greater the power consumption and the higher the corresponding cost. A brand that can independently develop and manufacture key components such as batteries and motors is generally a prerequisite for choosing a car, otherwise it is hard to say whether there will be problems such as motor burning and battery expansion in the future.

The workmanship of a controller reflects the strength of a company. Under the same conditions, the workshop controller is definitely not as good as the products of big companies. Companies that pursue materials and technology are relatively reliable, and the comparison can be seen. Many brand-name electric bicycles simply don't have the funds and technical strength to buy relevant testing equipment, and their products are not sent for inspection, so there will be more problems later.

Third, observe the appearance.

Whether the handlebars, wheels, chains and cranks are flexible to operate. If you don't want the paint color to fall off or yellow after the electric bicycle 1 year, you should look at the color selection of the car more. According to the instructions, check the working condition of the whole vehicle.

Fourth, after-sales service.

At present, the components of electric bicycles are not universal. If you don't need special after-sales service, there may be no matching parts in future maintenance. Therefore, when buying an electric car, we must pay attention to asking whether the brand has a special after-sales service network in this respect.

Finally, be sure to get the invoice, charger, certificate of approval, instruction manual, three-guarantee card, etc. And keep it safe. It is more convenient to solve problems with electric bicycles.

How to choose a good electric car charger?

1, digitally controlled by single chip microcomputer, the charging and discharging control parameters should conform to the unique charging curve of the battery, and the current determines whether the battery is full, not the voltage.

2. It has the function of positive and negative pulse repair and charging, which can break the lead sulfate crystal of the plate and repair the activity of the plate.

3. With automatic temperature compensation function, the charging voltage can be adjusted in time according to different environmental temperatures to ensure that it is not overcharged in summer and not undercharged in winter.

4. It has the function of balanced charging, which can prevent the voltage inconsistency between series batteries and keep the consistency of battery capacity.

5. Conventional reverse connection, short circuit, overcurrent, overvoltage, overtemperature and no-load output protection functions.

Select patented products

It is precisely because positive and negative pulse chargers have a good function of protecting batteries that some small factories without these technologies try their best to deceive consumers under the banner of positive and negative pulses.

Some large charger manufacturers apply for patents with the appearance of chargers, and then mark the patent number, which really confuses consumers. In fact, among the chargers for electric bicycles at present, only the patent number of positive and negative pulse circuits issued by the state is: 200420042802.2 (Shenzhen Kezhilin Electronics Co., Ltd.).

In other words, only products with independent intellectual property rights will be recognized and protected by the state, and all counterfeit and shoddy products cannot guarantee the function of positive and negative pulses, and their behavior will also be severely punished by law.

Choose a large number of brand-name electric vehicles and battery products.

The products of powerful manufacturers of positive and negative pulse chargers are often matched with brand-name batteries and automobile manufacturers. Because brand-name car manufacturers have very strict testing equipment and means, in order to pursue brand-name effect, most will buy high-quality accessories. In this way, some inferior chargers can't get in, so they can only turn to the secondary market and win the market by low prices (inferior components).
