electric cars must be regularly inspected during use. electric cars are vehicles for law enforcement departments. They have strong maneuverability, high police dispatch efficiency, and almost zero noise when driving. As a new type of urban management vehicle that is energy-saving, environmentally friendly, and infection-free, due to the relatively high frequency of use, electric cars will also malfunction and need to be repaired and replaced in time to avoid delays in use. Here is a list of some commonly used accessories for electric cars for reference when maintaining and repairing vehicle failures.
1. Battery
The battery is one of the core components of electric cars and the power source of electric cars. Therefore, special attention should be paid to how the battery is used: mainly the charging and discharging methods. Do not allow the battery to be completely discharged every time to avoid affecting the battery life; after use, charge it in time; the charging time is generally 8-10 hours, be careful not to overcharge to avoid damaging the battery; protect the battery from high temperature, cold, Erosion by wind and rain, etc. After the usage time reaches the expected life of the battery, the battery capacity will decrease significantly. At this time, the battery must be replaced in time to ensure the usage time of the
Electric Car.
2. Motor
The motor is another important component of electric cars, responsible for converting the power in the battery into driving force for the vehicle. Generally speaking, motors fail less frequently and do not need to be replaced as regularly as batteries. However, people should also pay attention to the operation control methods during use to reduce damage to the motor caused by improper operation.
3. Electronic control
electric cars generally use electronic control systems, which are characterized by simple and flexible operation and control, low intensity, and easy to master. At the same time, electronic control components are also susceptible to erosion by high temperature, high cold, wind and rain, causing problems such as circuit aging and component failure, leading to electronic control failure. This requires people to operate electric cars correctly, and at the same time frequently inspect their electronic control systems to discover and deal with potential problems in a timely manner.
4. Braking system
Brakes are accessories that are prone to failure. Some parts are prone to wear and tear. Regular maintenance and replacement of worn accessories is required to avoid delaying the use of electric cars.
5. Others
Others, such as tires and shock absorption systems, are also important accessories for electric cars and require regular maintenance.
In short, in the process of using electric cars, first, pay attention to correct operation and control to minimize damage caused by improper operation; second, regularly check the accessories, discover and deal with problems in time, and increase the service life of the accessories. Only electric cars based on this level can have relatively good performance; electric cars themselves are pollution-free and are a new type of vehicle. They are also a sight to behold when used by enterprises, so their appearance is also very important.
① First of all, the price is cheap. An ordinary
ELECTRIC CAR sells for about 20,000-30,000 yuan. For a fuel-type sightseeing car that costs about 200,000 yuan, its price is relatively cheap;
②At the same time, its use cost is also low. It is powered by batteries, so its daily use cost is only a few yuan.
③The whole-body electric design eliminates the daily maintenance costs of fuel-based sightseeing vehicles.
④At the same time, it is relatively simple to drive and does not require a professional driver`s license;
⑤The most important thing is that it does not produce any waste gas or waste liquid when driving, and truly achieves zero emission reduction.
The original battery has the characteristics of large capacity, light weight, long life, fast charging, high safety, high efficiency, etc. Its car appearance design is beautiful, the space is practical, and it is easy to operate. It is commonly used in domestic tourist attractions. The driving of an
electric car is completed by an electric motor driving the rear axle. The motors include DC motors, AC motors and other types. The DC brush motor consists of a magnetic field coil, an armature coil, a brush and a brush holder. The magnetic field coil generates a magnetic field, and the armature coil is forced to rotate under the magnetic field. If the stator coil and the rotor coil are connected in series, a series motor is formed. If the electronic coil and the rotor coil are connected in parallel, it is called a shunt motor. The stator coil and the rotor are not connected to each other. The stator coil is powered by another power source, which is called a separately excited motor.
