New energy vehicle maintenance requires a wide range of critical technologies, such as battery maintenance, driver system controller maintenance and start-up failure maintenance, as well as basic knowledge and skills. Battery maintenance, for example, requires familiarization with protection plate specifications, periodic recharge and decharging failures; power cuts and ash disposal are required for driver system controller maintenance. In addition, there is a need to have an in-depth understanding of the structure, rationale, etc. Of new energy vehicles and to master the use of maintenance equipment so as to be able to maintain new energy vehicles。
The importance of battery maintenance is self-evident. Batteries provide constant power to vehicles as “hearts” for new energy vehicles. Maintenance staff need to properly understand and apply the specifications of the battery protection panels, as do doctors who know the parameters of human organs. Regular charge-making allows batteries to remain in good working condition and to extend their useful life. In the event of a failure, care is taken to ensure that the operation in a state of power outages is carried out in such a way as to protect itself from secondary damage to the battery。
The maintenance of the driver system controller should not be underestimated. The first thing to do is power outage, which is a basic prerequisite for maintenance, just as power outages are to be secured before construction. They are regularly overhauled and fail-checked to identify potential problems in a timely manner. During maintenance, direct contact operating buttons are avoided and new malfunctions are prevented as a result of the error. At the same time, it is critical to have ash disposal, and excessive dust accumulation may affect the proper operation of the controller, just as the accumulation of miscellaneous items can hinder the operation of the machine。
Initiating failure maintenance requires the maintenance staff to have a full detection and analysis capability. When a vehicle starts to fail, a thorough examination of the overall condition of the vehicle is made to determine the approximate location of the failure, a step that is like a lead for a case by a detective. Precise measurements are made using specialized instruments to further target the failure point. Once a location has been identified, an in-depth analysis of the causes of the malfunctions is carried out, followed by targeted measures to repair them, which are as precise as a medical treatment。
In addition to these critical technologies, maintenance staff need to meet a range of basic knowledge requirements. Full knowledge of the structure, rationale, use, maintenance, repair, detection, failure diagnosis and removal of new energy vehicles is required. This means an in-depth understanding of the structure and working principles of the various components of the vehicle and how they work together. At the same time, basic knowledge about the use of new energy vehicle maintenance instruments, equipment, commonly used tools and tools is essential if they are to be mastered。
Basic skills are also essential. The ability to access and apply new energy vehicle maintenance information allows maintenance staff to keep up-to-date maintenance information and technology. It's like reading a car's “language”, fast-tracking circuit failure. The ability to read simple vehicle maintenance equipment instructions and vehicle maintenance technical materials with the help of a toolbook provides additional guidance for maintenance work. The ability to regulate independently the use of tools, instruments, vehicle maintenance, total overhaul, component testing and new energy vehicle performance testing ensures the quality and efficiency of maintenance work. The ability to develop and implement maintenance operations programmes that analyse, remove simple faults common to vehicles and perform maintenance quality testing and evaluation of vehicles that have completed maintenance operations continues to improve the level of maintenance。
In addition, new energy vehicles cover hybrid and pure electric vehicles, each of which has unique maintenance technology features. For hybrid vehicles, maintenance personnel need to understand in depth how internal combustion engines and electric motors work together, properly address battery maintenance, charging systems, etc., and are familiar with the characteristics and maintenance requirements of different types of batteries. The maintenance of pure electric vehicles, on the other hand, is more related to the frontier areas of battery technology, such as maintenance of battery management systems and battery replacement。
In sum, the maintenance of new energy vehicles is an integrated technical area covering a wide range of knowledge and skills. Each link is closely linked from key component maintenance techniques to comprehensive basic knowledge and skills requirements and to the special maintenance elements of hybrid power and pure electric vehicles. Only through continuous learning, practice and full mastery of these technologies can the maintenance staff protect the stable operation of new energy vehicles and promote the healthy development of the new energy automobile industry。
