THE CHARGING DEVICE

摘要

PURPOSE: A charging device for imposing charge against electricity used through a power supply device is provided to implement a reasonable price by imposing the charge based on used power quantity. CONSTITUTION: Charge is imposed based on the electric energy used with the kind of the used service. According to the used electric energy, the life time is reflected and charge is imposed. If the on-demand service is used, the use period of the apparatus is determined for supplying the customized service. The amount of current and voltage is measured by using a current sensor(12A) and a voltage sensor.
