BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a battery remaining capacity display device for an electric vehicle.

[0002]

2. Description of the Related Art The present applicant has previously disclosed Japanese Patent Application Laid-Open No. Hei 5-94593.
No. 1 proposed an electric vehicle notification device. As shown in FIG. 3 of the publication, the electric vehicle is provided with a display unit 9 such as a speedometer and a battery meter, and a scale between "F" and "E" is attached to the battery meter 9b, and the pointer indicates the remaining capacity of the battery. Is shown.

[0003]

However, it is difficult for an electric vehicle to replenish fuel in a timely manner like a gasoline or diesel engine vehicle. This is because charging stations are not yet complete. Therefore, when going out to a distant place, a driving method is adopted in which the vehicle is fully charged at the time of departure and turned back when the remaining battery capacity is reduced to half.

FIG. 13 is a view showing an example of a battery meter, in which a center mark 153 is clearly shown at an intermediate position (the relationship of L1 '= L2') between the full mark 151 and the empty mark 152. The driver may turn back the center mark 153 as a guide.

[0005] However, it is known that the battery deteriorates due to repeated charging and discharging, and it is conceivable that an error occurs between the indicated capacity of the battery meter and the actual remaining battery capacity. Therefore, an object of the present invention is to improve the position of a center mark in a battery meter to improve driving convenience.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention shows the remaining battery capacity between a full mark and an empty mark, and a remaining battery capacity zone in which a remaining capacity warning zone is marked before the empty mark. On the display device, the center mark is clearly indicated at a substantially middle position between the full mark side end of the remaining amount warning zone and the full mark.

[0007]

The remaining capacity of the battery is indicated between the full mark and the empty mark, and it is displayed that the remaining battery capacity is reduced to half at the center mark position biased toward the full mark.

When the main switch 56 is ON, the left and right lamps 135b and 135d are turned on. When the seat switch 102 detects the seated state and the side stand 22 is retracted, each lamp 135a is turned on.
To 135d blink one by one in sequence, and all the lamps 135a to 135d when the traveling motor 15 is in the operating state.
When d lights, each of these states is displayed. The speed indicator 136 indicates that the speed of the electric vehicle 1 is 3
When it becomes 0 km / h or more, it is lit. The side stand indicator 137 lights up when the side stand 22 is in the stand state. Turn indicator 1
38 is lit when turning right or left.

On the other hand, a full mark 126, an empty mark 127, and full marks 126 to
A capacity display mark 128 between the empty marks 127 is printed. The full mark 126 indicates the full capacity of the battery 35, the empty mark 127 indicates the empty capacity of the battery,
The capacity display mark 128 indicates the remaining capacity in the middle. The remaining amount warning zone 129 is printed before the empty mark 127, and the remaining amount warning zone 129 is
5 indicates that the remaining capacity is just before it becomes empty. The display panel 121 has the full mark 126 to the empty mark 1
A pointer 132 swinging between 27 is provided.

By the way, when the battery 35 is not deteriorated in the initial state, the pointer 13 is used when the actual remaining capacity is empty.
2 is the end 129a on the empty mark side of the remaining amount warning zone 129.
However, if the battery deteriorates or there is an error in the instrument system, the position indicated by the pointer 132 is shifted to the full mark side. In consideration of this, the zone width of the remaining amount warning zone 129 is determined.

A center mark 130 is printed at a substantially intermediate position between the end 129b on the full mark side of the remaining amount warning zone 129 and the full mark 126. The center mark 130 indicates that the remaining capacity of the battery 35 is about half of the full capacity. However, since the center mark 130 is incorrectly biased toward the full mark 126, the center mark 130 Of the battery 35 in the initial state of the battery 35 is more than half that at the time of full charge.

The operation of the battery remaining capacity display device will be described below. FIG. 12 is a diagram illustrating the operation of the remaining battery capacity display device. The center mark 130 is the capacity display mark 12
8 (the relationship of L1 = L2). Electric vehicle 1
When the battery 35 is fully charged, the remaining battery capacity display unit 125 indicates that the battery is full by pointing the pointer 132 (see FIG. 11) to the point S1.

Thereafter, the energy of the battery 35 is consumed by running the electric vehicle 1, and accordingly, the pointer 132 moves in the range of L1 on the capacity display mark 128 to display the remaining capacity on the way. . Since the energy of the battery 35 is consumed by further driving the electric vehicle 1, the pointer 132 points to the center mark 130 to indicate that the remaining capacity of the battery has been reduced to half, thereby returning the driver to the driver. Notify the timing.

At this point, if the electric vehicle 1 is turned back, the energy of the battery 35 is consumed by the turning back, and accordingly, the pointer 132 moves in the range of L2 on the capacity display mark 128, and the remaining capacity on the way is returned. Is displayed. When the electric vehicle 1 is turned back to the original departure point, the pointer 132
Indicates the point S2, which indicates that the battery 35 still has energy remaining in the range indicated by L3.

However, when there is a deterioration of the battery, an error of the instrument system, or the like, since the actual remaining capacity is smaller than the displayed remaining capacity, the surplus remaining amount of energy becomes smaller. Has no effect. The present invention can be applied to both a so-called battery meter with a pointer and an illuminated display type (without a pointer) battery meter.

[0032]

As described above, according to the present invention, the remaining capacity of the battery is indicated between the full mark and the empty mark, the remaining amount warning zone is marked before the empty mark, and the full mark side end of the remaining amount warning zone is indicated. By clearly indicating the center mark at a position approximately halfway between the part and the full mark, the remaining capacity for battery deterioration and errors in the instrument system is taken as a margin, and based on the idea of providing actual driving with other capacity, Since half of the capacity is clearly indicated to the driver, driving convenience can be achieved.
