The instrumental control of the charging balance makes it possible to quickly assess the efficiency and technical condition of the components of the vehicle power supply system. Factors have been developed that allow assessing the technical condition of the automobile alternator (efficiency factor) and its operation efficiency at the current combination of load and engine speed. The main parameters of the power supply system were measured using a four-channel analog data logger. Further research will be aimed at identifying the changes in the charging balance of the vehicle in case of failures of the automotive alternator and accumulator starting battery.
