Abstract
In an electric vehicle, a power supplier includes a software type condenser charging circuit and a hardware type condenser charging circuit. The software capacitor charging circuit operates when a controller controls the software type condenser charging circuit while monitoring a voltage between opposite ends at an initial charging stage. The hardware type condenser charging circuit is operated when the controller controls the hardware type condenser charging circuit without monitoring the voltage between the opposite ends of the DC-link condenser or by direct switching manipulation of a user.
Claims16
An electric vehicle driven by at least one vehicle driving motor, the electric vehicle comprising:
- a controller and an electric power supplier,
- wherein the electric power supplier comprises:
- a direct-current (DC) power source;
- a DC-link condenser to which electrical loads are connected;
- a software type condenser charging circuit connected between the DC power source and the DC-link condenser, and configured to operate when the controller controls the software type condenser charging circuit while monitoring a voltage between opposite ends of the DC-link condenser at an initial charging stage;
- and
- a hardware type condenser charging circuit connected between the DC power source and the DC-link condenser, and configured to operate when the controller controls the hardware type condenser charging circuit without monitoring the voltage between the opposite ends of the DC-link condenser at the initial charging stage, or by a direct switching manipulation of a user.
