The birth of any new thing has to go through strict market tests before it can become mature and stable. Although
Used Electric Car are not new, but for
fuel vehicles that have gone through a hundred years, the marketization of
Used Car The stability of is still a little immature, there are still many problems to be solved, and there is a long way to go.
With the promotion of the global new energy strategy, Used Car are strongly encouraged and supported by governments of various countries, and many countries have also given The timing of the prohibition of fuel vehicles, among which our country is the fastest in this regard, the high policy subsidies gave Used Car the opportunity to develop rapidly, and also quickly created a bunch of new domestic auto brands, of course a series of Safety issues have also been highlighted. Among them, the combustion problem of Used Car is of concern.
As a product that is closely related to our lives, the safety performance of automobiles is very important, and the burning of automobiles is a very serious safety problem. With Used Car With the increase in the proportion of vehicles, we have found that there are more and more burning incidents of Used Car. In the first half of this year, there have been at least 6 burning incidents to varying degrees. Many people believe that the culprit is the battery problem.
In fact, there are many reasons for the combustion of Used Car. Used
Electric Car is different from fuel vehicles. The main difference lies in its power system. Used Electric Car uses batteries as energy sources, and is composed of three parts: drive motors, electronic control systems and power battery packs. , and an electrified control system, so there are many reasons to analyze the spontaneous combustion, and there are generally possibilities in the following directions:
This wave of development of Used Electric Car has also gone through nearly 20 years. We see that Used Electric Car is also more and more integrated and platformized. This is a mainstream trend and a demand for large-scale marketization. At present There are two directions for more integration: one is the platform integration of the battery, and the other is the integration of the drive as a unit. At present, most motor drive systems integrate MCU, DC-DC, OBC, PTC and other functions. The power integration The unit is called PEU. As a very important unit, the safety and stability of PEU is very important. We have passed a series of strict tests such as PEU aging and loading, so that we can comprehensively inspect the performance of Used Car PEU under various working conditions. performance, ensuring that no security issues arise.
