Diagnosis and Maintenance of a High Voltage Battery Trainer
It's predicted that by 2030, there will be ~25.19M EVs in operation in the US*: Will your grads be ready?
The TruckTrain "Diagnosis and Maintenance of a High Voltage Battery" is an advanced training system developed by Lucas-Nülle, designed to equip automotive students with practical skills in diagnosing and repairing high-voltage (HV) batteries used in hybrid and electric vehicles. This comprehensive system emphasizes hands-on experience, allowing trainees to disassemble HV batteries to replace individual cells and sensors, thereby addressing system-critical situations that may arise due to malfunctions.
The HV battery is designed for easy disassembly, allowing for the replacement of individual cells and sensors. This facilitates practical diagnosis and repair, especially in critical situations arising from malfunctions in hybrid and electric vehicles. Training addresses faults that cannot be resolved independently, focusing on the HV system, its protective devices, and issues within the energy storage system. Diagnostics can be initiated using an integrated tester, with further analysis possible through standard HV measuring equipment. This process includes identifying faults in safety systems, temperature sensors, and battery cells, ultimately leading to a qualification in energy storage system maintenance.
Key Features:
- Modular Battery Design: The HV battery comprises 16 individually replaceable modules, each digitally coded and equipped with fault circuits, facilitating targeted diagnostics and repairs.
- Comprehensive Fault Simulation: With 50 fault-switching options across the HV system and battery, the trainer enables simulation of various real-world scenarios, enhancing problem-solving skills.
- Integrated Diagnostic Tools: Features such as real battery cell balancing with live data transmission, a digitally networked CAN bus battery management system with measurement interfaces, and CAN bus test sockets allow for in-depth analysis and troubleshooting.
- Advanced Charging Capabilities: Equipped with a CCS type 2 fast charging socket supporting both DC and AC charging, the system provides visualization of energy flow from charging ports to the HV battery.
Training Objectives:
- Developing the ability to understand customer complaints, perform operational testing, and determine appropriate diagnostic approaches.
- Gaining proficiency in reading fault memory and evaluating work safety measures.
- Learning to check the effectiveness of electrical safety measures on HV systems and replace high-voltage components safely.
- Becoming familiar with the location of components within motor vehicles and determining faults using circuit diagrams and function plans.
- Drafting inspection protocols, documenting results, and understanding measures to avoid hazards caused by voltage isolation faults.
By focusing on these areas, the TruckTrain system ensures that trainees acquire the necessary competencies to handle HV batteries effectively, meeting the evolving demands of the automotive industry.
