Description

The laboratory stand should be designed to carry out a set of practical work to study the power supply system of a modern car, the principles of its functioning and operating modes, as well as the formation of initial skills in diagnosing, maintaining and repairing a car as part of the course “Design, repair and operation of motor vehicles”.

General requirements
The stand must be a working model of a power supply system with basic control systems, such as a generator, a block of rectifier diodes, a voltage regulator relay, an ignition switch simulator and typical electricity consumers. As an internal combustion engine model, an AC electric motor controlled by a frequency converter should be used to drive the generator. The stand must implement normal and emergency operation modes of the system (input of at least 9 typical faults). Structurally, the stand should be a metal frame with a built-in front panel containing sheets of anodized aluminum. The front panel must be equipped with original automotive electronic units, display and control devices, and a color mnemonic diagram of the power supply system must be applied by metallographic printing.
