Air-conditioning HV Service & Repair training is for technicians and diagnosticians, who would like to be able to correctly service, diagnose and repair EV-AC systems. You must follow correct procedures when working on EV-AC systems and this training will give you the knowledge and confidence.
457.00 +GST
Prerequisites: It is advised that you have completed AECS’s Air-Conditioning Systems (ECAC1-1) training seminar.
Introduction & Safety
We will explain how EV-AC systems are built, from a technical perspective. There are very real dangers involved when working on EV systems. High pressures, burns and Electrocution are serious dangers and are not like the standard AC systems we are all comfortable with.
Maintenance
The need to service the system and what such a service entails is covered. From damaging the HV battery during charging, range reducing neglect, and total vehicle shutdown, are some of the problems we encounter during technical support on EVs. All easily prevented with knowledge and professionalism.
Wear and tear
So what is normal wear and tear on an modern HVAC system, when do you need to do fault finding, and when are things normal, just in need of maintenance?
Service & Repair
We’ll look at high voltage aircon system service and repairs on hybrids and EV’s. Typical losses to refrigerant and the effect on HV battery SOC and SOH. How can the AC system affect the High Voltage insulation, setting codes and shutting the vehicle down.
Simply letting it run until a complaint develops is NOT AN OPTION on EVs and Hybrids!
IHX
We cover heat recovery in modern AC systems.
High Voltage & Pressure
In the training, we will cover high voltage submerged compressors and vehicle heat pump systems, including high-pressure control, via compressor RPM and torque control inverter.
Oils & Injection
We will discuss the process and considerations transitioning from PAG to POE oil in HV systems. We will go over best practices for stop leak detection and refrigerant identification in the AC system, we’ll look at R1234yf systems and UV dye injection, and look at some damage done by your colleagues.
Battery temperature control
We look at late model vehicle active battery temperature control.
