This course from SAE International training partner, FutureTech*, is a MUST for everyone servicing hybrid vehicles. Nickel metal hydride (NiMH) battery systems continue primary battery technology in hybrid vehicles and have been since the 2000 model year.  If a technical professional doesn't know the fundamentals of NiMH operation it is impossible for them to perform a solid diagnosis or repair.  This course will concentrate on the NiMH technology, how it performs as it ages, how it can effect vehicle performance and fuel economy, and how to test it by using a scan tool.

Hybrid Electric Vehicle (HEV) models currently populating the vehicle electrification landscape indicate their dominance in the market. Although electric, plug-in, and fuel cell vehicles are making inroads in the market, the HEV stands as the market leader in adoption, and manufacturers have no plans on diminishing HEV production. HEV powertrain operation is totally different from the traditional vehicle. It is essential to understand the various operating modes and how failure modes in the hybrid system affect its operation.

The lithium Ion family of technologies are the primary technology for plug-in and electric vehicles but, it is also being found in hybrid products. Each family can have a different discharging voltage characteristic which effects vehicle and Scan Tool diagnostics.  This five-part series will provide the necessary information on all of the lithium technologies, cell balancing systems, failure modes, diagnostics, and how these battery packs can be repaired instead of replaced.
