Electric cars, power drivers, and name electric drive. Electric vehicle is divided into AC electric vehicles and DC electric vehicles. Usually, the electric vehicle is a battery that is converted into mechanical energy in a battery as an energy source, by a controller, a motor, etc.

The first electric vehicle was manufactured in 1881. The inventors were French engineers Guastavteruf, which was driven by a lead-acid battery, which was driven by DC motor, and the electric cars have been Higher changes have occurred, and the types are also diverse. Electric vehicle vehicles occupy a share of the national economy.

However, it is in line with the national energy-saving and environmental protection trend, which greatly facilitates short-distance traffic, which is most important to play an important use in the national economy through the savings and environmental savings and protection. Electric vehicle classification 1. Electric vehicles can be divided into: electric bicycle, electric motorcycle, electric wheel car, electric four-wheeler, electric tricycle, electric scooter; in accordance with power source: pure electric car, Runout electric car, hybrid electric vehicle, fuel power battery car.

2. According to the power supply, it can be divided into two major categories. First, connect external power supply to obtain electric power, in addition to fuel power cells, energy storage devices, supercapacitors, etc.

as electricity. 3. Classify: Pure electric car, hybrid electric vehicle (series, parallel, mixed), fuel power battery electric car.

4, according to the shape, you can be divided into electric wheelbarrow, electric bicycle, electric motorcycle, electric tricycle, electric four-wheeled car. 5. Classifying: electric car; electric car; electric bicycle (comparable bike); electric motorcycle, electric truck, electric patrol car, folding car, surf, shooting car, motorcycle, wheelchair stroller, beach car, Scooter, electric balancing car, electric sightseeing vehicle, electric golf car, electric sanitation car, electric bus, electric police car, electric forklift, magnetic vehicle, electric van, electric tractor, electric rail vehicle, electric power car, electric garbage Car, electric recreation car, electric burnout, electric classic car, light lithium tram, other solar electric car, etc.

In addition, there are safety electric vehicles, anti-theft electric vehicles, antifreeze wall electric vehicles, etc. Advantages of the advantages of electric vehicles: 1, small lanes: saving energy compared to the cars, saving parking spaces, no waste of energy. 2, economic environment: electric car can be rode only, do not refuel, do not discharge the exhaust gas, and will not pollute the air.

3, efficient and convenient: Due to the small body of electric car, it is better than the car, which is conducive to the traffic congestion, mitigate traffic pressure. 4, the price is cheap: suitable for work. The price of electric bicycles is generally around 1,000 yuan to 3,000 yuan.

5, safe and simple: as long as you can ride a bicycle, electric bike is still very fast. Just started to go to the road must be slow. Disadvantages of electric cars: 1, battery problem: easy to electricity, only suitable for short-distance riding; inconvenient charging, less charging station; battery aging is serious.

2. Safety problem: electric car tires with cheap price are easy to puncture; brakes are easy to fail; there is no bicycle and flexible. 3, maintenance fee: maintenance is not convenient, tend to touch small problems, such as tire puncture, tie, brakes, not smooth, controller is easy to burn, battery should be rechargeable, etc.

4, easy to be stolen: For example, the battery, there is also an electric bicycle itself is also easy to be stolen. Differential differences in electric vehicles and battery cars, electric vehicles, power drivers, and name electric drive. Electric vehicle is divided into AC electric vehicles and DC electric vehicles.

Usually, the electric vehicle is a battery that is converted into mechanical energy in a battery as an energy source, by a controller, a motor, etc. Electric cars include: electric bicycle, electric motorcycle, electric wheelbarrow, electric four-wheeled vehicle, electric tricycle, electric scooter; in power source: pure electric car, increased range electric car, hybrid electric vehicle, fuel power battery car. 2.

The battery car is supplied by the battery (battery), a pure electric motor vehicle driven by a motor (DC, Communication, String, Herangik). Special vehicles with short-distance movement in a specific space. At present, domestic battery car is important for sightseeing passengers, public security patrols, handling goods, electric sightseeing vehicles are used in parks, scenic spots, leisure resorts, universities, hospitals, golf courses, real estate companies, etc.

The important use of electric patrol cars is to conduct public security patrols in the station square, and the human flow intensive place is an important purpose of electric handling vehicles is in the factory, port pier, logistics warehouse, etc. An important use of electric sanitation vehicles is used to clean the site, clean the road, transport garbage, etc. 5 electric car purchase attention 1, watch the brand, there are many electric car brands.

Considering that electric vehicles are long-term consumer goods, as travel tools are always concerned about people's security issues, therefore should choose a good reputable brand, including long operating hours, low quality, good quality, reputation, etc. Reference standard. 2, the model model determines the purchase model according to the actual situation of the rider.

Electric bicycles can generally be divided into mini, standard, multi-functional four. The four models have an advantage. Everyone should put their own needs in the first place when purchasing.

3, check the strength requirements and performance requirements of the accessories electric bicycle components should be higher than bicycles. When purchasing, the user wants to see the quality of the whole vehicle. Such as: the welding of the frame and the front fork and the defects in Yuan face, whether the manufacturing of all parts is excellent, whether the double support is strong, whether the tire is selected by the brand, the smart part is rustic, etc.

4, a set of new batteries for 36V / 12AH is generally about 50 kilometers, and the maximum length of riding is more than 35 kilometers per day (due to road conditions affecting the actual renewal mileage) ), The maximum distance of the ride is more than 50 kilometers per day, and it is necessary to consider whether there is a possibility of two intervals. If there is no possibility, it is not suitable for purchasing electric bicycles. 5, heavy service, due to the current electric car parts, the maintenance can not reach socialization, so the purchased electric bicycle ~ must pay attention to whether there is a special maintenance service department in the region, if the picture is cheap and ignored the after-sales service, It is easy to.

6 Electric Car Maintenance 1, first adjust the height of the saddle and the car to make it in the safest and most comfortable position, especially the saddle height, it is best to stop in both feet during the cycling process. 2, whether the test brake device is effectively reliable, and the test is cut off after braking, whether the motor has stopped working. 3, check the power: When the power is turned on, view the power situation on the display, especially when used after long-term shelving, especially.

In addition, check if the electric horn, the light, etc. related to the driving safety components are effective! 4, check the rotation part: whether the front and rear wheels and pedals, cranks, sprockets, chains, flywheel operation is normal, there is no vast. 5, check if the tire pressure is right.

6. First, you must first abide by road traffic rules. Don't cross the red light, you should ride on the slow driveway, don't ride on the expressway.

Turn off the electric door when crowded in the traffic, human riding. When you turn, slow down, don't drive at high speed, a small angle is sharp, causing an extraordinary force to make a car accident. 7, cut people.

Since the battery capacity of electric bicycles is not large, the motor power is not high, so the weight of the electric bicycle is around 80kg (including the rider), if a riding is riding, it is bound to increase the electric machine load, speed up the battery, thereby reducing the battery The service life of the battery motor has also violated traffic regulations. 8, uphill, upper bridge, anti-wind riding, should be used at the same time, reduce the battery, motor load. Method of riding at startup: General electric bicycle has zero start function, that is, when it is stationary, turn on the electric door, turn the speed to turn the car to start driving.

However, at this time, the start current is two to three times the normal driving, and the impact on the motor and the battery is very large, especially the battery. Therefore, in order to extend the continuation mileage of the charging and battery life, you should start the foot when startup, when the foot is three, there must be a certain number of speeds, and then turn on the circuit, this is very busy, traffic lights More importantly important. Frequent zero start, will shorten the battery life.

7 Electric Vehicle Battery Maintenance 1, hydrotherapy to the vulcanized battery, first discharge the battery, go out of the raw electrolyte and inject the density of 1.10 g / cm3, less than the thin electrolyte, i.e.

, add water to the battery, to dilute the electrolyte Improve the solubility of lead sulfate. The current below 20H is used for a long time in the range of no more than 20 ¡ã C to 40 ¡ã C. Finally, the electrolyte density to the standard solution concentration in the battery is adjusted with a slightly high electrolytic solution in the case of sufficient electrolyte.

Can be released, the capacity is restored to more than 80%, which can be considered successful. 2, shallow cycle large current charging method to the vulcanized battery And eliminate vulcanization. 3, chemical repair method for the sulfurized battery, pour the raw electrolyte, add pure water and sodium sulfate, sulfate, tartaric acid, etc.

, take normal charge and discharge, then pour out pure water to add a slightly high density acid solution Adjust the amount of acid solution in the battery to the standard liquid concentration, and the capacity is restored to more than 80%, which can be successfully repaired. 4, pulse repair About the vulcanized battery, can be used to charge the battery charge and discharge by some dedicated pulse repair instruments to eliminate vulcanization.
