Introduction to Battery Electric Vehicle (BEV): Diagnostics and Maintenance

This course covers various topics on how to diagnose and maintain battery electric vehicles (BEVs). It provides an overview of diagnostic trouble codes (DTCs) and their relevance to BEVs. You will learn the definition and purpose of on-board diagnostics (OBD), the history of OBD, and understand the importance of the OBD-II standard in the automotive service industry. This course discusses the unique features of BEVs and their diagnosis using OBD, focusing on monitoring characteristics and diagnostic procedures. It also covers common BEV performance failures, and the test equipment needed to diagnose these issues. You will learn how to access OBD data in BEVs by examining communication networks and portals, utilizing OBD-II scan tools, and employing diagnostic tools like meters. Finally, this course presents the maintenance requirements for BEVs and compares the advantages and disadvantages of maintaining BEVs versus gasoline vehicles. 

Note: This course provides generic knowledge of servicing BEVs. Always read and follow the specific service information for the vehicle you work on before performing any maintenance. 

This module covers the foundational aspects of On-Board Diagnostics (OBD), encompassing its definition, purpose, and practical applications. You will learn about the historical evolution of OBD, including its dynamic transformations over the years. Additionally, this module discusses the OBD-II standard in the automotive industry, addressing its role in diagnosing and resolving issues within vehicle systems.

Lessons:

  1. On-Board Diagnostics (OBD) Definition and Purpose 
  2. Brief History of On-Board Diagnostics (OBD) Development 
  3. On-Board Diagnostics II (OBD-II) Standard and its Importance in the Automotive Industry 

This module will discuss the inner workings of BEVs – from their unique features to the essential practices of monitoring and diagnosing potential issues. You may be familiar with some of the main features of gasoline-powered vehicles, such as two-pedal driving; however, as some battery electric vehicles (BEVs) are unique, you will notice they only have one-pedal driving. We will discuss these and the other features that are unique to BEVs. While basic car maintenance is familiar territory, BEVs require a more proactive approach. We will look at the essential components for effective battery monitoring in BEVs to ensure the battery packs’ safety, performance, and longevity. Finally, we will discuss the importance of the live-dead-live test procedure, and the steps involved in effectively disabling high-voltage systems to ensure the safety of technicians.

Lessons: 

  1. Unique Features of Battery Electric Vehicles (BEVs) and their Diagnosis Using On-Board Diagnostics (OBD) 
  2. Characteristics of Monitoring  
  3. Diagnostic Procedure: Live-Dead-Live (LDL) Test 

This module covers the communication networks and portals in BEVs, distinguishes between various types of on-board diagnostics (OBD) scan tools, and examines the role of diagnostic tools in maintaining battery electric vehicle (BEV) safety. This module will enable you to identify and differentiate between communication networks, their applications, and topologies in BEVs. Additionally, you will learn to compare scan tool types and justify the preference for manufacturer-specific scan tools. Furthermore, this module covers the role of the National Fire Protection Association (NFPA), discusses category (CAT) ratings, and contrasts digital multimeters (DMMs) and insulation meters.

Lessons: 

  1. Communication Networks and Portals in Battery Electric Vehicles (BEVs) 
  2. On-Board Diagnostics (OBD) Scan Tools 
  3. Diagnostic Tools: Meters 

This module covers the advantages of on-board diagnostics (OBD) for battery electric vehicle (BEV) owners and technicians, focusing on on-board diagnostics (OBD), preventive maintenance, early issue detection, and streamlined troubleshooting processes. This module discusses the unique maintenance requirements of BEVs, including the cooling system, 12-volt battery, and tires, and strategies to effectively utilize service information, technical service bulletins (TSBs), and diagnostic trouble code (DTC) charts to overcome challenges and optimize repair procedures.

Lessons: 

  1. Preventive Maintenance and Early Detection of Issues 
  2. Streamlined Troubleshooting and Repair Processes
