With the development of economy and the progress of society, the application of new energy vehicles is becoming more and more common with the increasing awareness of environmental protection. The application of new energy vehicles, on the one hand, has facilitated people's lives and provided great convenience for people's travel; On the other hand, the problem of environmental pollution has been effectively improved, and the use of energy has been greatly reduced. Through investigation and research, it is found that in recent years, people's demand for new energy vehicles shows a rising trend year by year. thus it can be seen, New energy vehicle maintenance It has a good market development prospect.
1、 Circuit Fault Analysis of New Energy Vehicles
When the new energy vehicle is running, after a long time of operation, the temperature of the generator itself will gradually rise, and the circuit may be damaged. At the same time, during the ignition operation, the car is basically in the state of power generation per second. After long-term use, the circuit is relatively easy to damage. With the development of automobile manufacturing industry, the application of electronic control system is more and more common. Although it has certain advantages, it increases the consumption of electricity. For example, take the intelligent starting system as an example, which mainly starts the car by generating electricity.
If the circuit is in operation for a long time, it may lead to a load condition in the operation of the car. In addition, the consumption of other functions on the generator may make it difficult for the car to bear these loads. The situation may be short circuited in the light, or the vehicle may not run normally in the heavy, resulting in a series of accidents with serious consequences. According to the relevant investigation, when the new energy vehicle cannot bear the load, the electronic equipment may be damaged or the power may be cut off. If some key equipment has problems during operation, traffic accidents are likely to occur.
(II) New energy vehicles Circuit fault maintenance technology
Through a more intuitive diagnostic method, when a car has a problem, it will generally have excessive temperature or abnormal noise, which is relatively easy to find. Just find out where the problem occurs, and then take targeted solutions through detailed inspection. However, there are still some hidden faults, which are hard to be seen directly by the naked eye, whether for drivers or maintenance personnel. For example, when a tire is punctured, it is difficult to see it visually at the beginning, but it can only be seen after it is deflated. There are also some problems. For example, when the engine has a problem, only by opening the engine cover one by one can we gradually find the problem.
2、 Air conditioning fault
At this stage, most cars have air conditioning systems, and there are two main faults in air conditioning. It refers to the problem of failure to cool or leakage. If the air conditioner fails to cool normally, it may be due to insufficient refrigerant, but ordinary people do not know about this problem, and can only know it through professional maintenance and inspection. In this case, it is very likely that the circuit has been used for a long time, resulting in aging, or that individual components have been damaged.
The circuit or interface inside the air conditioner is complex. Even if there is a problem in one small part, it is likely to cause the whole air conditioning system to fail to operate normally. In addition, for new energy vehicles, the air conditioning system is in a relatively closed space, which is difficult to repair and disassemble. It can be seen that if there is a built-in fault system in the car, it is very important and plays an irreplaceable role.
To sum up, it is very important to solve the problem of new energy vehicle failure and master the key technology of maintenance. In this regard, it is necessary to continuously improve the maintenance level of fault maintenance technology to provide an important guarantee for the operation quality of new energy vehicles.
