Hybrid Traction System

Course Details

For several decades the hybrid technology is being widely deployed in different models for many of the most renowned manufacturers. This technology incorporates a number of innovations, not only by the fact of having two engines to manage vehicle traction, but for all the new concepts they have had to look to make it feasible (electric motors, drive train, generator current, high-voltage batteries, emission reduction, etc.) and the different variations that have resulted from them.

Although the course covers general concepts applicable to the hybrid “universe” such as labelling, classification, equipment individual and collective protection, safety in handling such vehicles, etc. We will also analyze a particular case, the Toyota Auris, because it is a significant and widespread technology.

The main objectives of this course are:

• Identify the different classifications of hybrid vehicles and technologies.
• Knowing protective equipment and handling protocols prevention and emergency actions when intervening on these vehicles.
• Learn the techniques of checking, loading and maintenance of high-voltage batteries.
• Identify the different types of high-voltage batteries applied to hybrid systems.
• Know the basics of electric motors and generators.
• Knowing the different technologies applied to trans-axis hybrid.
• Identify and know how to control the various components of the hybrid system Toyota Auris.
• Know the technologies applied to the braking system, air conditioning and engine combustion Toyota Auris
