How to distinguish the good from the bad when buying an electric bicycle is a headache for many consumers. The following is what I collected and arranged for you to choose a good electric car. I hope it will help you! Welcome to read the reference study!
how to choose a good electric car charger
1. brand selection
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 option.
second, the internal quality
the quality of the four parts and the adaptability of the four parts are very important to improve the performance of the whole electric bicycle. The specific car can look at these four big pieces 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 car selection, otherwise it is hard to say that there will be problems such as motor burning and battery swelling 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 large 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 purchase relevant testing equipment, and the products are not sent for inspection, and there will be more problems in the later stage.
Third, observe the appearance
Whether the handlebars, wheels, chains and cranks operate flexibly. If you don't want the paint color of the electric bicycle to fall off or yellow after one year, you should look more at the color selection of the car. Follow the instructions and check the working condition of the whole vehicle.
iv. After-sales service
At present, the components of electric bicycles are not universal. If special after-sales service is not required, there may be problems of no matching components in future maintenance. Therefore, when buying an electric car, you must pay attention to asking whether the brand has a special after-sales service network in this area.
finally, be sure to get all the invoices, chargers, certificates, instructions, three-guarantee cards, etc. and keep them properly. In this way, it is more convenient to solve problems with electric bicycles.
How to choose a good electric car charger
1. It is digitally controlled by a single chip microcomputer. The charging and discharging control parameters should conform to the unique charging curve of the battery, and the current determines the battery's full charge, 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 electrode plate and repair the activity of the electrode plate.
3. It has the function of automatic temperature compensation, and can adjust the charging voltage in time according to different ambient 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 functions of reverse connection, short circuit, overcurrent, overvoltage, overtemperature and no-load no-output protection
Choose patented products
Because positive and negative pulse chargers have a good function of protecting batteries, some small factories without these technologies also try their best to deceive consumers with the banner of positive and negative pulses.
Some larger manufacturers of chargers apply for patents based on the appearance of chargers, and then put the patent number on them, which really confuses consumers. In fact, at present, among the chargers for electric bicycles, only the patent number of positive and negative pulse circuits issued by the state is: 2424282.2 (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 counterfeit products can't guarantee the function of positive and negative pulses, and their behavior will be severely punished by law.
Choose a large number of products for brand-name electric vehicles and batteries
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 of them will buy high-quality accessories. In this way, some inferior chargers can't enter, so they can only turn to the secondary market and win the market by low prices (inferior components).
