    Hybrid/EV Diagnostics (EMS1-4)

    Quick Facts
    Course ID:EMS1-4
    Duration: 2 Days

    The EMS1 series seminars are all parallel and do not need to be attended in any particular sequence. This very nice 2 day seminar deals with Hybrid/EV systems in a very practical manner, you will come away from this seminar being confident to maintain, diagnose and repair these 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 any modern car. 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
      Emission testing

Please note: in the seminar we use oscilloscopes. Signals referred to are scope signals.
The diagnostician can bring his/her own scope, or our high speed dual channel scopes (ATS) can be used.

After Will from Dale Nixon Automotive Ltd attended the EMS14 training seminar in Auckland (1 08 2013).
Will wrote as comment in the evaluation form that as most value to him was: "Servicing and safety requirements"

Pre requisite: From our experience we advise that the diagnostician has completed the AED 'Automotive Electronic Diagnostic' 2 day training seminar, regardless achieved level through other training systems or experience!
