Equipping Schools for EV Education: Essential Tools and PPE

The demand for skilled EV technicians is rising. Schools with existing automotive programs now have a unique opportunity to expand their offerings by introducing hands-on EV training, preparing students for the fast-evolving industry.

However, safely training students to work with EVs requires specialized personal protective equipment (PPE), tools, and equipment beyond those used for traditional internal combustion engine (ICE) vehicles. This guide breaks down the essential components for setting up an effective EV training program, from PPE to specific tools and equipment.

Understanding the Unique Requirements of EV Education

Electric vehicles operate at high voltages, presenting unique electrical hazards compared to conventional vehicles. Instructors and students must prioritize safety and adopt an unwavering commitment to careful handling procedures. An effective EV curriculum should start with a comprehensive introduction to electrical safety, followed by focused training on the PPE, tools, and equipment necessary for working with high-voltage systems.

By investing in the right tools and protective equipment from the start, schools can meet industry standards and give students hands-on experience in a secure learning environment.

1. Essential Personal Protective Equipment (PPE) for EV Education

PPE is a non-negotiable in any automotive program, especially for EVs, as they expose technicians to potentially lethal high-voltage currents. Ensuring that both students and instructors are equipped with the right PPE will mitigate risks and promote safe learning.

It is important to note that most HV PPE in particular is only a requirement when working on an energized system. That being said, when in doubt, wear protection.

Key PPE items include:

By instilling PPE habits early, students will develop a solid understanding of electrical safety procedures, making them well-prepared for the industry.

2. Tools and Equipment Required for an EV Education Program

The tools and equipment necessary for EV education are different from those used for ICE vehicles. They include diagnostic equipment, high-voltage test tools, and battery handling equipment designed for safe operation on EVs. Here’s what every program needs:

Diagnostic Tools

EVs rely heavily on advanced electronics, making diagnostic tools essential. Here are the core diagnostic tools for an EV-focused curriculum:

• OBD-II Scanner with EV Capabilities: An OBD-II scanner is essential for reading trouble codes and diagnosing issues specific to EVs, like battery health and regenerative braking. Ensure the scanner is compatible with electric drivetrains and can read EV-specific codes.
• Thermal Camera: Batteries can overheat, and thermal cameras allow students to monitor battery temperatures safely. This tool is also useful for diagnosing overheating in other components.
• Multimeter with High-Voltage Testing Capability: A multimeter capable of measuring up to 1,000 volts AC/DC is a must. Look for models with CAT III or CAT IV ratings to ensure safe measurement of high-voltage components.
• Insulation Resistance Tester: This tool checks the insulation of EV wiring to ensure there’s no risk of current leakage. It is often referred to as a megaohmemeter or a “megger”. While they share many of the same functions as a multi-meter they are essential for teaching students how to verify the safety of high-voltage cables and systems as they can measure resistance, isolation, and continuity with much more accuracy.

Battery Service Tools

Working on EV battery packs presents specific challenges due to their weight, complexity, and safety requirements. Schools should invest in these tools to facilitate safe battery handling:

• Battery Lift Table: EV batteries are often large and heavy. A lift table makes it easier and safer to remove and install batteries for testing or repairs.
• Battery Cell Balancer and Analyzer: Students need to understand how to evaluate battery cell health. A battery balancer and analyzer will allow them to test cell voltages, resistance, and capacity, giving them a firsthand look at maintaining battery packs.
• Battery Terminal Torque Wrench: High-voltage batteries have specific torque requirements to ensure proper connections. An insulated torque wrench allows students to securely fasten battery terminals without risking short circuits.

Safety Equipment for High-Voltage Systems

In addition to diagnostic and battery service tools, high-voltage safety equipment is critical for handling EV components safely.

3. Setting Up a Safe and Effective EV Workstation

An organized, safety-oriented workstation is essential for teaching EV skills. Schools should consider these key elements:

4. Training and Curriculum Development

Equipping students with the knowledge to work safely on EVs is just as important as providing the right tools and equipment. Consider these tips to build a comprehensive EV curriculum:

Conclusion

Setting up a hands-on EV education program in an established automotive school requires careful planning and investment in the right PPE, tools, and equipment. By providing students with a safe, well-equipped environment, schools can ensure that the next generation of technicians is prepared to work on the EVs of today and tomorrow.

Ensuring that students master both safety and technical skills is essential to their future success and the credibility of the program. As the automotive industry evolves, so too must our educational programs.

The investment today in EV-focused training will pay dividends by equipping students to confidently and safely enter the electric vehicle workforce.
