Electric vehicles have become an indispensable transportation tool in people's lives. They mainly include electric bicycles, electric motorcycles, and electric tricycles. Electric vehicles are not only green and flexible, but also provide a lot of convenience for people's lives and work. However, many friends are confused when they buy electric cars. In the end, what kind of electric cars are good and how good electric vehicles are? What? In addition to the electric car to the card? How to prevent electric vehicles? Solve these problems for everyone today.
How to buy an electric car?
1. Look at the electric car brand models
a. Look at the brand: Consumers should select the top ten brands of electric vehicles that have long operating hours, low repair rates, good quality, and good reputation. For example, companies that have passed the ISO9001-2000 quality management system are selected.
b. Re-service: As the components of the electric vehicles are not yet universal, maintenance cannot achieve socialization. Therefore, the electric vehicles must pay attention to whether there is a special maintenance service department in the region. If the plans are cheap and neglect the after-sales service, it is very important. Easy to fool.
c. Selection of models: Electric vehicles can generally be divided into luxury type, ordinary type, front and rear shock type, lightweight type and so on. Luxurious function is complete, but the price is high, the common type structure is concise, economical and practical; the lightweight type is lightweight and flexible, but the journey is short. Consumers should pay attention to this when purchasing electric car brand products.
2. Look at the main configuration of electric vehicles
The key to improving the intrinsic quality of electric vehicles is: motors, controllers, chargers, and batteries. The quality of the four major parts and the adaptability of the four major parts are critical to the improvement of the overall vehicle performance. Since the battery, motor, charger, and controller each have specific good operating parameters, when selecting the four major parts, it is also necessary to pay attention to the perfect adaptation of the parameters between the four major parts. Only high-quality adaptation can make the four big parts play extremely well. Extend the service life of the battery to improve the performance of the vehicle.
a. Motor: In addition to light electric tricycles that use electric wheels, the main choice is a low-power DC series motor. With strong overload capacity, the product is relatively mature.
b. Controller: The controller of the speed control handle (or the speed control pedal) is configured to make the speed control of the motor easy, that is to say, the speed can be arbitrarily adjusted according to the wishes of the driver. The controller also has many auxiliary functions: current limit protection, undervoltage protection, soft start function, anti-vehicle function, fault self-diagnosis function and so on. All these governors are not available on all governors in the market. Consumers should pay special attention when purchasing them.
c. Charger: The main function is to charge the battery's electrical equipment, convert AC to DC and control its current and voltage into the battery and store it. Under the premise of not affecting the battery life, it is mainly configured by the manufacturer to achieve a good charging effect.
d. Battery: The continuation mileage of a group of new batteries with a capacity of 36V/12Ah is generally about 50 km. Generally, the longest distance to ride is about 35 km per day. It is more appropriate (because the road condition affects the actual continuation mileage). For those who ride for more than 50 kilometers a day, it is necessary to consider whether there is a possibility of recharging twice in a day. A good battery should have the following requirements:
a. The safety performance is good. No electrolyte leakage under normal use, no battery expansion and rupture.
b. The discharge performance is good. The discharge voltage is stable and the discharge platform is gentle.
c. Good shock resistance. The fully charged battery is completely fixed and shakes for 1 hour at a frequency of 4 mm with a frequency of 16.7 Hz. There is no leakage, no battery expansion and rupture, and the open circuit voltage is normal.
d. Good impact resistance. The fully charged battery naturally falls from a height of 20 cm to 3 cm on a hardwood board with a thickness of 1 cm. No leakage, no battery expansion and rupture, and the open circuit voltage is normal.
e. Good over-discharge resistance. At 25 degrees Celsius, the fully charged battery is discharged for 3 weeks with a constant resistance (resistance is only equivalent to the required resistance of the battery 1CA discharge), and the recovery capacity is above 75%.
f. good charge resistance. At 25 degrees Celsius, the fully charged battery 0.1CA charges for 48 hours, no leakage, no battery expansion and rupture, open circuit voltage is normal, and the capacity maintenance rate is above 95%.
2. Look at the details of the electric car
a. First select the appearance quality of the vehicle, mainly to see whether the trademark, decals are in good condition, and whether the surface quality of paint parts, plating parts, plastic parts and aluminum alloy parts is satisfactory.
b. Check the quality of the assembly of the vehicle. It should be: a. All kinds of screws are fastened in place without loosening. b. The handlebars, wheels, chains, cranks, and pedals should be flexible; the rims should be round and the amount of circular runout is small. c. The handlebars, saddles, mud boards, hangers, and brackets must be installed symmetrically or symmetrically. There should be no obvious skewness.
c. The switch key and battery lock are to be tested. The electric key lock, battery lock, and tool box lock should be the most convenient one.
d. Open the switch and turn the shift handle to check the stepless speed change and brake (brake) power failure and brake effect, and check if the motor runs smoothly and the sound is normal.
e. Through test riding, experience the performance of the entire vehicle and decide whether to purchase it. There is a problem on the spot to solve the problem. If it cannot be resolved, you can propose a new car.
f. Finally, the invoice, charger, certificate, manual, and three packs of cards should be collected and properly kept.
Do electric cars need to be on the card?
As for the licensing of electric vehicles, some provinces need it. Some provinces do not need it. Look at the local regulations. Consult the local vehicle management office for specific conditions. This is because the “new national standard” has only policies and there are no detailed rules, but local rules need to have a process, and some provinces will only be able to see the relevant rules. What are the licensing procedures for electric vehicles? (Locales may differ, please consult local traffic control department for details)
1. Required documents for electric vehicle license plates:
Identity zheng, electric vehicle purchase mai hair piao or income ju, electric vehicle certification. On the card not only need to purchase a car invoice, their own relative identity, but also need the certification of electric vehicles. The certificate and the electric vehicle are all corresponding to each other. There is only one copy. If you want to re-submit, you must find the manufacturer. There are certain expenses in the middle. When consumers purchase electric vehicles, they must also ask whether they have a certificate of compliance. If they have a certificate, they must keep it properly.
2. Procedures for licenses on electric vehicles: payment of purchase tax; insurance on new vehicles; detection of criminal investigations. (Detection station office): Non-exempt inspection vehicle over-line detection; payment, fill in the form; extension number camera; data collection; (Zhejiang office management hall): submit information, the owner of the signature; civil jing on the vehicle inspection and confirmation; selection number, receipt of the receipt; license plate sealed installation photo; driving license, registration certificate.
The National Standard "Motor Vehicle Operation Safety Technical Conditions" (GB7258-2012), which was implemented on September 1, 2012, clearly stipulates that electric vehicles with speeds of 20 km to 50 km and weights of more than 40 kg, as "motorcycles "Incorporate motor vehicle management. The jing department will accept registration of products that comply with the standards of motor vehicles, and have a motor vehicle announcement issued by the Ministry of Industry and Information Technology as well as the Ministry of Industry and Public Information. Drivers must legally apply for licenses, driver's licenses, and insurance purchase procedures.
How to prevent electric vehicles?
1. Choose a parking place. Try to park in the carport while parking, and don't park the electric car in places with few people or in remote areas. If there is no carport, try to park the electric car in the bank, neighborhood or storefront. Because these fields have all security, salespersons or cameras, thief is less likely to commit crimes.
2 locks have a choice. In the choice of locks, try to choose locks for the ring or arc-shaped locks, and try to buy brand locks. In addition, to install tire locks, because the thief chose to commit the crime of electric vehicles, almost all is not on the tire lock.
3. Install anti-theft alarm. This is also a more effective anti-theft measure. When you temporarily stop the discharge of the motor vehicle, try to park it within your sight. When you are locked, you should lock the car with the ground lock and fixed object as much as possible to prevent it from being stolen.
4. Battery anti-theft lock installed. The battery is the most valuable part of an electric bike, so many thieves are particularly optimistic about the battery. So try to add a battery anti-theft lock to increase the thief stealing difficulty.
5. Choose a security electric vehicle. Choose a high-security anti-theft electric vehicle with good performance.
