FIELD: electricity.
SUBSTANCE: charging device, comprising a unit of charging voltage release; a unit for setting of switching duration; a unit to generate a PWM signal; a unit to generate reference voltage; a unit to limit reference voltage; a unit to generate detected voltage; and a unit to control charging voltage. The unit to generate reference voltage generates reference voltage for detection of whether the charging voltage achieved the target charging voltage by means of smoothing of the PWM signal, generated from the unit of PWM signal discharge. The unit to limit reference voltage limits at least one of the maximum value or minimum value of reference voltage generated by the unit of reference voltage generation.
EFFECT: unification of a charging device to provide for charging of accumulators with different voltages.
