GMTO EV training - EV 5 | EV Technology in Practice

Information

Introduction

Electric vehicles have now become a common presence in workshops, which means that issues with these vehicles are also increasingly common. This training has been developed based on practical experiences. After a short introduction, you will dive into hands-on problem-solving, and by the end of the day, you’ll be ready to apply this practical knowledge immediately.

Prerequisites

To participate in this training, a basic understanding of EV1 and EV2 is required. It’s also recommended to have completed EV3 and EV4 courses.

Key Points

• Insulation faults and potential equalization
• Diagnostics on the high-voltage system
• Diagnostics on the charging port
• Structure of EV error codes
• Measuring e-components

Topics

The following topics will be covered in the course:

• Practical-focused training – You’ll work directly on real-life issues and case studies to gain hands-on experience.
• Insulation faults – This is a common issue. A potential equalization test after repair is essential to ensure safety.
• HV relays in the battery pack – The HV relays serve multiple functions. By analyzing the relay switching processes, you can gain insight into how the vehicle manages them.
• Battery pack issues – In EV4, you learned a lot about these; in EV5, we’ll take it further with practical examples.
• Disconnecting a vehicle from a charging station in case of an issue.
• Handling a 12-volt lithium-ion battery – How to work with these specific battery types.
• Function and diagnostics of charging connections – Covers both AC charging and DC fast charging, along with diagnostic techniques.
