In addition, preferably in 1, when electrical storage device 40 is configured in (namely in car) above under body 10, by covering electrical storage device 40 with electromagnetic parts 42 can be shielded, thus electromagnetic wave can be suppressed more fully on the impact in car.Further, preferably in 1, because rectifier 35 is also configured in the bottom (namely car is outer) of under body 10, therefore can reliably suppress electromagnetic wave on the impact in car.
[variation 1]
Fig. 7 is the configuration of the main portion of the elec. vehicle of the variation 1 of embodiment 1 being observed to invention from vehicle side and the figure that obtains.With reference to Fig. 7, in elec. vehicle 1A, in the structure of the elec. vehicle 1 shown in Fig. 1, electrical storage device 40 is configured in the bottom of back seat 44.Other structures of elec. vehicle 1A are identical with above-mentioned elec. vehicle 1.Although do not illustrate especially, also electrical storage device 40 can be configured in the bottom of front stall.
Also the effect same with embodiment 1 can be obtained by this variation 1.
[variation 2]
Fig. 8 is the configuration of the main portion of the elec. vehicle of the variation 2 of embodiment 1 being observed to invention from vehicle side and the figure that obtains.With reference to Fig. 8, in elec. vehicle 1B, electrical storage device 40 is configured in the bottom of middle control desk 46.Other keystone configurations of elec. vehicle 1B are identical with the elec. vehicle 1 of embodiment 1.
Also the effect same with embodiment 1 can be obtained according to this variation 2.
[embodiment 2]
Fig. 9 is the configuration of the main portion of inventing from the observation of vehicle side for the elec. vehicle of embodiment 2 and the figure obtained.With reference to Fig. 9, in elec. vehicle 1C, in the structure of the elec. vehicle 1 of the embodiment 1 shown in Fig. 1, electrical storage device 40 is also together configured in the bottom (namely car is outer) of under body 10 with powered syntonizer 20 and cable 30.Other keystone configurations of elec. vehicle 1C are identical with elec. vehicle 1.
Figure 10 is the enlarged drawing around the under body of the elec. vehicle shown in Fig. 9.With reference to Figure 10, in this elec. vehicle 1C, electrical storage device 40 is also configured in the bottom (namely car is outer) of under body 10 made of iron.Electrical storage device 40 is configured in the bottom (i.e. car outer) of under body 10, although be electrically connected with cable 30 and powered syntonizer 20 across rectifier 35, so can propagate to electrical storage device 40 along with the frequency electromagnetic waves accepting electric power due to electrical storage device 40.So, replacement covers the electrical storage device 40 on the top (namely in car) being configured under body 10 by shielding electromagnetic parts 42, and configure electrical storage device 40 in the bottom (namely car is outer) of the under body made of iron 10 with high effectiveness, thus can electromagnetic wave be reliably suppressed to reach in car.
As mentioned above, preferably in 2, electrical storage device 40 is configured in the bottom (namely car is outer) of under body 10 made of iron, so the electromagnetic wave produced from electrical storage device 40 is also shielded by under body 10.Therefore, the harmful effect to the electrical equipment in car caused by electromagnetic wave produced with accepting electric power from power equipment supply also can be suppressed according to this embodiment 2.
In the respective embodiments described above, as elec. vehicle, the power being distributed driving engine 124 by distributing means for power supply 126 is illustrated with the series/parallel formula hybrid electric vehicle that can transmit to drive wheel 128 and dynamotor 120, but the present invention is also applicable to other forms of hybrid electric vehicle.That is, the present invention be also applicable to such as be using only drive dynamotor 120 and use driving engine 124 and regenerated energy in the so-called series hybrid electric vehicle only being produced the propulsive effort of vehicle by dynamotor 122, the kinetic energy that only driving engine 124 produced carry out reclaiming as electric energy hybrid electric vehicle, be active force with driving engine and carry out the motor auxiliary type hybrid electric vehicle etc. of assisting with motor as required.
In addition, the present invention is also applicable to and does not possess driving engine 24 and the electronlmobil only travelled with electric power, except electrical storage device 40, also possess the fuel-cell vehicle that fuel cell is used as direct supply.In addition, the present invention is also applicable to the elec. vehicle not possessing boost converter 112.
Should think, whole aspects of embodiment of disclosure are only illustrate instead of restricted contents.Scope of the present invention is not the explanation of above-mentioned embodiment but is represented by request claim, means all changes comprised with in the meaning of claims equalization and scope.
