Abstract

An electric charging apparatus is provided. The electric charging apparatus includes a ground determination signal generating unit measuring a current signal or voltage signal that is generated from power applied from a power supply unit, the ground determination signal generating unit generating a signal for determining whether the power supply unit is normally grounded on the basis of the current or voltage signal, a power control unit generating a power control signal on the basis of a ground determination detecting signal generated from the ground determination signal generating unit, and a power cutoff unit cutting power supply to a target device to be charged on the basis of the power control signal.

Description

technical field [0001] Embodiments of the present invention relate to a charging device, in particular to a charging device capable of determining whether a power supply device is grounded. Background technique [0002] Air pollution in big cities is getting worse. Exhaust emissions from vehicles are one of the main causes of air pollution. Under such circumstances, research into the commercialization of so-called electric vehicles using electric power, which is a non-polluting energy source, as a power source is actively progressing. The electric vehicle receives electric energy from the outside to charge a battery therein, and then uses the voltage charged in the battery to obtain driving power as mechanical energy through an electric motor coupled to wheels. That is, since the electric vehicle needs to drive the motor by using the voltage charged in the battery, it is necessary to use a high-capacity rechargeable battery. Accordingly, there are charging devices for cha...
