Nickel Metal Hydride (NiMH) Hybrid Battery Systems PD291811

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. NiMH battery systems continue to be used in Hybrid Electric Vehicle (HEV) applications and provide an excellent foundation in high voltage battery pack systems.  This course will include NiMH battery cell operation, cell/module failure modes, diagnostic testing methods, battery hardware components, battery stress testing techniques, and how some of these areas differ from Lithium systems.  

At the conclusion of this five-part series, participants will be able to identify the condition of a battery pack, servicing instead of replacing it, and using specific testing methods outlined in this course. Ford, GM, Honda, Lexus, Toyota hybrid electric vehicle products are featured in this course.

Objectives

By participating in this eLearning course, you'll be able to:

• List the different formats of a NiMH cell or module and explain the advantages and limitations of NiMH technology
• Explain the functions of battery power andbattery energy
• Explain what major sensing and component control systems operate in conjunction with the battery controller system
• Using the NiMH Module Voltage Sensing Circuit, describe how this circuit functions to communicate battery module/cell voltages to the battery controller
• Describe the operation of a battery module/cell temperature sensing circuit
• Describe the purpose and operation of battery pack contactors, the battery pack Pre-Charge circuit and the battery pack current sensor
• Describe NiMH cell aging and the Apparent Capacity Loss function
• Elaborate on how geographical area, terrain, and drive cycle can affect the operation of a NiMH battery pack (cell)
• Visually identify battery module or cell electrolyte leaks and bus bar corrosion
• Explain how a battery pack controller aging can affect how voltages can be skewed
• Describe how a battery pack cooling system can effect battery module/cell longevity, premature module/cell failure, and overall performance
• Explain the battery pack stress test process and how the results can help determine what actions need to be taken
