Description

  The present invention relates to a power supply system for an automobile.

  Since August 2005, the present applicant has started a demonstration test of an “external power supply type idling cooling / heating system” at Tojin Truck Station in Yamato City, Kanagawa Prefecture, in cooperation with a certain car manufacturer.

  This externally powered idling stop cooling and heating system promotes idling stop by supplying power directly from the outside to trucks that have many opportunities to wait with the engine on for a long time to reduce environmental impact. It is aimed.

  Currently, reduction of emissions of greenhouse gases such as CO2 and toxic gases is required, and idling stop is attracting attention as one of the effective measures to solve this. The challenge is to effectively suppress the driver's nap and idling during unloading and unloading.

  FIG. 1 is a diagram showing an outline of the external power source type idling stop air conditioning system. The truck 2 parked in the parking lot 7 has a package cooler 6 independent of the air conditioner of the vehicle as an air conditioner installed on the driver's seat (on the roof) and used for cooling the driver's cab. For heating, an electric blanket and a heat storage mat (not shown) are provided in the cab. Here, the package cooler 6, the electric blanket, and the heat storage mat are referred to as an external power supply type air conditioner.

  A power supply stand (external power supply facility) 3 as shown in FIG. 2 is installed in the parking lot 7, and system power is supplied to the external power supply type air conditioner through the cable 4.

  By implementing idling stop using this system, it is possible to expect an environmental load reduction effect of about 77% for CO2 during cooling and about 97% for NOx per hour with a large truck. Furthermore, no exhaust gas is generated in the parking lot, and noise can be reduced.

  In addition, the present inventors do not know the existence of an open patent document or a non-patent document that discloses a power supply system for an automobile according to the present invention described below.

  FIG. 3 is a view of the parking lot 7 where the external power source type idling stop cooling / heating system 1 is viewed from above. Here, since the power supply stand 3 is required corresponding to each parked truck 2, the power supply stand 3 is installed for each parking space of the truck 2. The parking spaces shown in FIG. 3 are one row in the vertical direction as viewed in the figure, but in an actual large parking lot, a plurality of parking spaces are prepared in the vertical direction. Power is distributed from the power receiving / transforming equipment 8 connected to the system power (not shown) to each power supply stand 3 via the cable 9.

  Since it is necessary to install the power supply stand 3 for each parking space, a large number of power supply stands 3 are established.

  The installation space for installing such a large number of power supply stands 3 is very large. Furthermore, when a large number of power supply stands 3 are established in the parking lot, it becomes a very troublesome obstacle for the automobile 2 traveling on the road surface. Furthermore, it is expensive in terms of cost to prepare a large number of power supply stands 3 and install them at predetermined positions in the parking lot.

  Further, when the driver receives power supply, the power supply stand 3 and the power receiving device 5 of the automobile 2 are connected using the cable 4, so that the driver needs to go out of the vehicle and operate.

  Several ideas that can further improve the convenience of a power supply system for automobiles have been proposed through demonstration tests currently being conducted.

  Therefore, an object of the present invention is to provide a power supply system for a new automobile.
