Abstract:

The prevailing view in the available literature on the subject is that the main goal of green transport is to reduce environmental pollution. Therefore, a noticeable trend is the replacement of the internal combustion engine with a hybrid system, and in the latest only with an electric motor. Therefore, the ongoing changes in the design of modern motor vehicles, in particular the power units themselves, fit into the idea of green transport. The researchers emphasize that one of the determinants of the development of such vehicles is the limited possibilities of storing electricity in rechargeable batteries. Thus, this paper presents considerations regarding the current diagnostic capabilities of a high-voltage battery in a selected hybrid vehicle. The impetus for the topic of research was the popularization of models using two types of drives, i.e. the internal combustion engine and the electric motor. As a consequence, this process led to the development and increase in the number of devices intended for their diagnostics. In the research process, the authors used the MegaMax 66 diagnostic device and a high-voltage battery tester. This innovative approach allowed for comprehensive diagnostics of the drive system. Due to the fact that in the process of operation, many times the reading of error codes using a diagnostic tester alone is not sufficient. It is necessary to check the condition of the battery in order to assess the current parameters.  Thus, the aim of the article itself is to draw attention to the essence of the research problem undertaken regarding the approach to the diagnosis of high-voltage batteries in hybrid vehicles. On the other hand, the recipients of the research are all participants of the automotive market, broadly defined in the literature.
