Hybrid, Plug-In, & Electric Vehicle Battery Packs:
Why Technicians Will Need to Know the Differences for Analysis and Diagnostics

Hybrid, Plug-In, and Electric vehicle technologies have implemented a multitude of battery technologies into a significant number of vehicle platforms.  From 2000 – 2010 Nickel Metal Hydride (NiMH) dominated hybrid vehicles and it continues to dominate the hybrid market today.  However, in 2009 Lithium technology began to make its mark in the hybrid market and this technology has continued to move steadily into the hybrid market with each passing model year.  Plug-In and full electric hybrids have been predominantly Lithium technology from the very beginning and these vehicles have been strictly Lithium for many model years. 

Every technology has iterations during its life cycle.  The frequency of these iterations becomes less frequent as the technology matures.  Battery technology is not maturing, but, it is iterating quickly due to the rapid cell technology changes.  When applying these changes to the repair industry where vehicles must be - it has a profound effect on the technicians that must perform the data analysis, diagnostics, and repair.  Unlike traditional vehicles that are far more mature and can be repaired by using pattern failure (pattern failure symptom recognition) analysis for a given vehicle manufacturer and model, advanced technology vehicles with electric drives and battery packs cannot be diagnosed using pattern failure recognition.  With changes in battery cell chemistry, sometimes by model year, pattern failure recognition is impossible.  Furthermore, when cell chemistries change, this means that the data and how it will react with various driving conditions is very different from year to year – even for the same vehicle model.
​
To solve this dilemma, service technicians and their managers need to recognize that the necessary analysis and diagnostic treatment for the advanced technology vehicles is significantly different than a traditional vehicle.  Technicians will need to accept that they will need to learn the operation of the different battery technologies so they can determine how to interpret scan tool data and how to manipulate the vehicle system to force the diagnostic process into something less gray and more binary.  So, it’s time for technicians to go back to school; the train has already left the station.
