Automotive Starting and Charging Systems unit (AV-SCS)
PL-201364
The Automotive Starting and Charging Systems Unit, “AV-SCS”, developed by EDIBON, offers a complete solution for theoretical and practical training in modern vehicle ignition and charging systems. This educational unit allows students to acquire the knowledge and skills needed to analyze and understand the function of key components such as the DC starter motor, alternator, solenoid relay, battery charging circuit, and ignition switch.
Students can explore how various circuits are powered based on the ignition key position, simulating the different system phases—from initial power-up and preheating to full engine start. The simulation is enhanced with an electric motor that replicates the function of a combustion engine and drives the alternator, enabling battery charging verification and circuit testing at critical points of the start-up process.
The “AV-SCS” includes an instrumentation panel with built-in fault simulation capabilities. This allows learners to practice diagnostics and troubleshooting procedures based on realistic scenarios. In addition, hands-on exercises are provided to deepen understanding of alternator voltage regulation and battery behavior during charge and discharge cycles.
Fault simulation features cover common failures in components like the battery, alternator, and motor, creating a safe environment for students to apply repair techniques. Designed to align with current and future industry requirements, the “AV-SCS” introduces students to advanced energy systems used in hybrid and electric vehicles.
The unit integrates a wide array of real automotive components and systems for comprehensive learning in energy management and electrical system diagnostics.
