新能源汽车高压系统故障诊断及维修技术研究

Research on Fault Diagnosis and Maintenance Technology of High Voltage System of New Energy Vehicles

随着当前我国的快速发展,人们的生活水平得到了全面的提升,对于衣、食、住、行都有着追寻着物质上的追求,这就造成了我国出现了能源方面的危机,所以,相关的部门就针对于能源危机的问题,设计出了新能源汽车,并且在社会上得到了广泛的使用。这类新能源汽车,在进行实际的使用时,其内部的高压系统是起到非常重要的支持作用的,如果这个系统出现问题,那么汽车的整体都会受到影响,不能够进行工作。因此,相关的人员,就应该不断地进行深入研究新能源汽车中的内部高压系统,做到掌握更加全面化的诊断以及相应的维修技术,这样才能够在问题出现之后,第一时间进行措施解决。本篇文章笔者从新能源汽车当中,针对于高压系统的故障做了简要的分析,并且主要描述了预充电方面所存在的问题,提出了相应的问题解决方法。

With the current rapid development of China,people’s living standards have been comprehensively improved.They are pursuing material pursuit for clothing,food,housing and transportation,which has led to the energy crisis in China.Therefore,relevant departments have designed new energy vehicles for the problem of energy crisis,which have been widely used in the society.When this kind of new energy vehicle is actually used,its internal high-voltage system plays a very important supporting role.If there is a problem with this system,the whole vehicle will be affected and cannot work.Therefore,relevant personnel should continue to conduct in-depth research on the internal high-voltage system of new energy vehicles,so as to master more comprehensive diagnosis and corresponding maintenance technology,and take measures to solve the problems at the first time.In this paper,the author makes a brief analysis on the faults of high-voltage system from the perspective of new energy vehicles,mainly describes the problems existing in precharge,and puts forward the corresponding solutions.
