Thermal Management in Hybrid & Electric Vehicles
Course Details
The high-voltage systems of electric vehicles do not need a large amount of cooling in comparison with an internal combustion engine. Nevertheless, they do need cooling in order to function correctly and prevent faults in the internal electronic and electrical components. The high-voltage cooling is divided into two groups: the powertrain and the high-voltage battery, the latter being the most delicate element. As regards cooling systems, there are passive and active types and the method used can be forced air, conditioned air and or by means of coolant.
The main aims of this course are:
- To identify the different types of circuits and elements that make up the vehicle’s climate control.
- To recognise the importance of the characteristics of the different types of refrigerants.
- To establish the system’s maintenance processes.
- To make use of the climate control verification and adjustment equipment and tools.
- To understand the need for cooling.
- To understand the operating principles of cooling in high-voltage systems.
- To classify the circuits and elements that form part of the cooling system.
- To analyse the thermal management of the high-voltage components.
- To differentiate between the passive and active cooling and heating systems.
- To carry out assembly and maintenance operations on the cooling system.
- To verify and adjust the cooling systems.
