Instrumental monitoring of the load of the automotive alternator during the movement of the vehicle

Abstract

Abstract The charge balance of the vehicle indicates whether the starter battery is being charged while the vehicle is running. For normal operation of the power supply system, the charge balance must remain positive, preventing progressive discharge of the battery. A decisive influence on the balance of electricity is provided by the current output of the alternator, which depends on the rotor speed. The maximum current output of the alternator is described by a current-speed characteristic depending on the technical condition of the alternator. In the process of vehicle movement, the rotor speed and alternator current strength vary over a wide range determined experimentally. The ratio of these parameters is the alternator efficiency coefficient, which can be used to assess the technical condition of the automotive alternator. The productivity of the vehicle’s charge balance is objectively evaluated by the alternator load factor. Further research will be aimed at identifying changes in the charge balance of the vehicle in the event of a malfunction of the automotive alternator and starter battery.
