Vehicle Electrification Systems Standards: Vehicle Cabin HVAC Systems

Vehicle Electrification Systems Standards Curriculum Description:

The Vehicle Electrification Systems Standards curriculum is provided by the Northwest Engineering and Vehicle Exchange (NEVTEX) and developed by Central Oregon Community College (COCC) and Rio Hondo College (RHC). COCC and RHC worked together "to develop curriculum and training standards for technicians in hybrid electric vehicle (HEV), electric vehicle (EV), and Fuel Cell (FC) vehicle systems." This curriculum was developed with the intention of addressing industry needs by partnering with industrial and educational representatives to obtain input and assistance to develop:

1. new approaches to prepare an advanced technologies workforce,
2. licensure procedures and policies to ensure the safety of technicians, their employers, and clients, and
3. collaboration between educational and industrial partners in the development of new standards and practices.

The Vehicle Electrification Systems Standards are divided into 11 topics. This section of the standards covers the topic Vehicle Electrification Vehicle HVAC Systems. The other 10 topics and a Master Acronym and Definition list are available to view separately.

Vehicle Cabin HVAC Systems Description and Contents:

This section of the Standards includes the following four lesson plans: X. a - Acronyms and Definitions; IX. b - Vehicle Cabin HVAC Systems Components; IX. c - Vehicle Cabin HVAC Systems Operation; IX. d - Vehicle Cabin HVAC Systems Diagnostics and Service. Each lesson plan covers different aspects of on-board high voltage charging systems. The lesson plans include a description, objectives, tools, tasks, and outcomes.

The 10-page acronyms and definitions lesson plan covers terms related to vehicle cabin HVAC systems.

The 3-page lesson plan on vehicle cabin HVAC systems components provides tasks so that students, “will be able to identify all cabin and high voltage battery pack HVAC components, trace high voltage wire/cable system routing of all electrical harnesses, and identify low voltage cooling system components and electrical circuits.”

The 3-page lesson plan on vehicle cabin HVAC systems operations, where students will compare BEV, PHEV, FCEV, and some HEV systems to understand if the HVAC system has correct functionality, which will be determined using appropriate test instruments. 

The 3-page lesson plan on vehicle cabin HVAC systems has students use “test vehicles, diagrams, OEM service information, scan tools, electronic test equipment, and worksheets” to demonstrate their ability to assess and document HVAC systems and component operations.
