NEW! LITHIUM ION FAMILY BATTERY SYSTEMS
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. At the conclusion of this course from SAE training partner FutureTech*, you will will be able to identify the various Lithium formats, aspects cell aging, rebuilding concepts, and understand how to use Scan Tool PIDs to help analyze, diagnose and repair the battery pack. GM, Honda, Hyundai, Nissan, Tesla, Toyota electric and hybrid vehicle products are featured. While the duration of this five-part series is 10 hours, the estimated time to completion, including knowledge checks and the final learning assessment, is eleven hours. LEARNING OBJECTIVES By participating in this On Demand Course, you will be able to: • List the advantages and disadvantages of lithium technologies and the automotive lithium battery formats • Describe the discharging and charging process of a lithium battery cell • 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 • Identify the components in air and liquid cooling system for lithium battery packs • Identify and describe the components of a battery management system cell balancing system • Explain the difference between how vehicle instrumentation displays battery pack SOC% vs. actual battery pack SOC% • Relate in how SEI Layer growth effects battery cell operation • Describe how failure modes on the positive and negative electrode evolve • Compare the difference between battery power vs. capacity • Explain the battery pack Stress Test process and how the results can help determine what actions are needed
