Detailed description of the EMS 1-4 (Hybrid Management Systems 1 part 4)
This two days seminar is parallel to the EMS 1 part 1,2 & 3 seminars.

This very nice 2 day seminar deals with Hybrid systems in a very practical manner, you will come away from this seminar with the comfortable feeling you can Maintain, Diagnose and Repair those vehicles! It is both hands on and theory.
Customers will come to see you with their hybrid when there is a problem, will you turn them away? You are the first stop for them!
Realise that you do not need to be some scientist to work on the Hybrids, you need to be skilled just like you need skills to work on modern cars.
This course will provide you with those skills!

The following topics are covered:



• System Layout
  Identify the main components of the Hybrid system and know where they are.
  
  
• How does it work
  How does the three phase AC motor work on DC.
  Understanding rotational magnetic fields in a simple way without calculations.
  How does the ECU control torque on the Motor Generators. Speed and torque control.
  Generating electricity with the Motor Generators and the voltage height control on NHW10/NHW11 and NHW20.
  How does the power flow run through the gearbox and in which direction does everything run under various conditions, movies, real parts and drawings.
  How does the inverter work and how to measure safely the high voltages. What are the individual parts in the inverter, and how does it generate a rotating magnetic field.
  How does the HV battery work, how it is build up and what can you repair, also a short piece on the electro chemical construction of the battery.
  What does SOC mean and how it is important to us.
  The 12Volt system
  MG position sensor.
  Over view of the IMA system (Honda)
  
  
• How to make the system safe to work on
  How long before the system has been powered down and is safe to work on.
  What can you work on and what needs to be treated with the utmost care inside the inverter, the battery unit and the motor generators.
  What is still live and dangerous when the safety switch has been removed
  
  
• How to diagnose
  How to diagnose and repair the battery module, what can and what can you not do.
  Battery equalising.
  Diagnose when something is wrong with the Motor generators and when something is wrong in the inverter.
  How to handle HV cables, How to connect your tool to High voltage items.
  Thermo sensors in the battery unit.
  The 12 Volt system and how to jump start.
  The MG position sensor signals.
  
  
• Maintenance.
  Coolant of the inverter and transaxle system, how to replace and bleed
  Brakes, how to replace brake fluid and how to bleed this regenerative brake system.
  Brake testing on a rolling road
  Engine maintenance.
  Storage and jump starting
  Gearbox oil, checking and finding leaks to HV system
  Aircon service
  Fuel filter
  Pre-purchase inspection
  Towing
  Emission testing
