Attend our workshop
High-voltage systems are no longer the future – they are already part of everyday workshop reality.
Lucas Nulle have developed an EV training rig that lets learners safely work on real-world high-voltage systems without needing a full vehicle.
It means you can deliver consistent, repeatable fault scenarios, increase hands-on training time, and reduce risk and cost. It’s already helping organisations bring their EV training up to industry standard quickly.
For training providers, this means one thing: learners must be prepared to diagnose and repair HV systems safely, confidently, and in line with current standards.
We will cover the functionality of the Lucas Nulle Car train including:
- Contactor variants, switching sequence’s, weld checks
- DC/DC converters (typically 300–800V DC down to the vehicle’s 12V system)
- 12V battery jump starting (number 1 EV fault)
- Traction motor control (The inverter and control software are central to EV performance, efficiency, and reliability)
- Shut down/isolation procedures (Correct isolation is fundamental to all safe EV maintenance and diagnostic work, very commonly misunderstood)
- Charging (During charging, the vehicle communicates with the charger to manage voltage, current, battery temperature, and safety functions such as insulation monitoring and contactor control)
- Energy flows in hybrid variants (HEV & PHEV series, parallel, or series-parallel—the vehicle control system continuously manages energy distribution)
- Basic and advanced fault finding/diagnosis (A critical part of HV vehicle diagnosis is insulation testing)
- Equalization potential cables (During HV diagnostics or after collision repair, technicians should always inspect and test bonding cables because physical damage or improper reassembly can compromise vehicle safety)
We shall be hosting several workshops looking at this technology throughout the event. If you would like to attend one, please fill out the form below:
