The inverter of the hybrid car is responsible for converting the high voltage of the battery for use by the electric motor, and conversely, the low voltage after recuperation converts to high for the battery charge. For this reason, the main breakdowns of the inverter of a hybrid car are associated with its cooling system, so you need to repair the inverters in a timely manner
First, the limited service life of the inverter cooling pump requires the driver to replace this part in a timely manner.
Secondly, high loads and high operating temperatures are the reason for the mandatory replacement of the inverter coolant according to the car service book. When replacing the antifreeze in the hybrid circuit, it is necessary to use a fitting to pump air. The airiness of the hybrid circuit can lead to irreparable consequences.
Also, timely replacement of antifreeze allows you to save the radiator, the channels of which are very easily clogged with foreign particles and clots that form in the spent antifreeze.
Third, the inverters can be mechanically damaged. Particularly weak link are the attachment points. In the event of minor collisions or any other mechanical collision, microcracks or cracks may appear on the inverter housing in places inaccessible to inspection. And there are many cases when moisture gets into such places, then there are all sorts of problems in the work, which leads to the need to repair the inverters immediately!
If the diagnostic equipment shows an error code of the type “P0AHX”, it means that your hybrid car has problems with the inverter. There is a special transcript for all errors, so it is not difficult for service center specialists to find out what exactly the problem is.
Equalizing a battery of a hybrid car is a process of long-term charging of the battery by the engine to the level that can give the maximum battery. During this process, each element of the car’s high-voltage battery is charged. Serviceable elements charge quickly enough, faulty or “tired” longer. You can start the equalization process after connecting to the car. At the same time you can see how worn out the battery. With the help of the scanner you can see the difference between the maximum and minimum charged element, if this difference does not exceed 20%, the battery is in normal condition and equalization will improve its performance. But if more than 20% difference in charges, it is worth thinking about repairs.
