  • Patent number: 8441229
    Abstract: A system for recharging a plug-in hybrid vehicle and a control method are provided to recharge a battery with exterior AC electricity plugged in. The system includes a motor operated as an electric motor or a generator, a battery in which DC voltage is stored, an inverter disposed between the motor and the battery, a plugged in exterior AC electric power source supplying electrical energy, a single phase inductor disposed between the inverter and the AC electric power source, a switch which electrically connects or disconnects the motor, a current sensor that detects current value supplying to the motor, and a controller which controls the switch to disconnect electric connection between the inductor and the motor and controls the inverter not to supply current to the phase which is not connected to the inductor when the AC electric power source is plugged in.

  • Patent number: 8385044
    Abstract: A film capacitor is provided that includes a case in which a film cell is incorporated and a heat radiating plate including a heat absorption unit being positioned adjacent to the film cell while not being in contact with the film cell for absorbing heat and a heat radiating unit being exposed to the outside of the case. Preferred film capacitors can perform a stable operation and have durable lifespan, even when an inverter adopting the film capacitor is mounted on a trunk room and an engine room, by effectively cooling heat generated from a film cell of the film capacitor.

  • Publication number: 20120138274
    Abstract: The present invention provides an apparatus for effectively cooling electric modules such as an inverter and an LDC installed in a hybrid electric vehicle or an electric vehicle. The cooling apparatus for electric modules of a hybrid electric vehicle or an electric vehicle secures a uniform cooling efficiency and achieves an excellent heat radiating efficiency at the same time by realizing a new type of cooling system adapted to separately manage heat transfer in the cooling water passages of first and second electric modules by separating an upper passage of the first electric module and a lower passage of the second electric module using a cooling separator.

  • Publication number: 20120044647
    Abstract: The present invention provides an apparatus for cooling parts of a hybrid electric vehicle. The apparatus cools the main heating parts of a motor driving system, including an inverter, in the HEV. A heat dissipater may also be provided and equipped with different heating parts, such that the heating parts share the heat dissipater. A channel for a coolant to flow is formed in the heat dissipater, and the heat dissipater defines heat transfer paths for transferring heat generated from the heating parts to the coolant. The heating parts include a power module, an inductor, and a film capacitor.
