FIELD: electrical engineering.
SUBSTANCE: according to the current evaluation method at the vehicle battery terminals, the vehicle generator voltage is controlled, during which the generator control voltage Ub is stabilized for a certain period on the voltage value close to the battery voltage equilibrium, as a result, battery current ICha tends to zero, calculating resistance R of electrical components of vehicle by ratio R = Ub/ICarb, where ICarb is the current consumed by the vehicle and equal to the current supplied by the generator, during said control of the generator voltage at a voltage value close to the equilibrium voltage of the battery, values of generator voltage regulation are changed to higher value Uh and current IChah of battery charging is calculated by means of ratio IChah = IAlth-Uh/R, where IAlth is current supplied by generator.
EFFECT: technical result is optimizing evaluation of vehicle battery charge.
