Part of Lesson Plan: Hybrid Safety & Service (updated) by Dennis Johnson

Activity Overview / Details

Safety First!!  Students will get their safety glasses, rubber gloves, and remove any and all jewlery. Students will bring their sample inspection/identification task sheets, and the two remaining blank inspection sheets and follow the instructor into the lab for demonstration on how to locate key components on a hybrid system. 

Instructor will demonstrate where to locate the 12 V auxiliary battery, hybrid vehicle (HV) battery pack, electric motor, inverter and gasoline engine (ICE), as well as how to remove the service plug.  Instructor will inform students they should always allow 5 minutes after the plug has been removed before any service is performed to allow all powered modules to time out to prevent accidental electrical shock.

NOTE: ALL HIGH VOLTAGE COMPONENTS AND CONNECTIONS ARE BRIGHT ORANGE!!!!!

Once students have observed demonstration on location of key hybrid components, instructor will demonstrate proper procedure for removing the service plug.
