The battery charging time at home or at a charging station may take a long time of about 10 to 18 hours for full charging. This charging time can be short if the battery is not fully charged, but if the battery runs out of power, the electric vehicle cannot run, so it is desirable to ensure sufficient charging time and charging amount. On the other hand, an electric vehicle can also continue driving without charging time by exchanging a discharged battery for a charged battery. However, since the battery standard may differ depending on the manufacturer or capacity of the electric vehicle, it may not be possible to prepare a charged battery compatible with the electric vehicle at the supply base, and it may not be possible to replace the battery in a timely manner.

Also, the replaceable battery 6 can be used in common for any of the replaceable battery mounting portions 421 , 412 , 22 provided at different positions on the vehicle body 2 .

The replaceable battery mounting portion to which the replaceable battery 6 can be mounted can be provided in a portion common to electric vehicles 1 of different manufacturers (including electric vehicles 1 of different types) with a common configuration and size. Thereby, the replaceable battery 6 can be used as a common component common to the electric vehicles 1 of different manufacturers.
In addition, the replaceable battery mounting portion to which the replaceable battery 6 can be attached can be commonly provided in the electric vehicle 1 regardless of different manufacturers, but different standards can be used for each power capacity required to drive the electric vehicle 1.
In this case, the replaceable battery 6 has a power capacity corresponding to the power consumption of the driving motor 411, and is composed of a plurality of types of battery main bodies (details not shown) that differ for each power capacity required to drive the electric vehicle 1 (for example, each of a large-sized vehicle, a medium-sized vehicle, and a small-sized vehicle).

Next, an example of utilization of the replaceable battery 6 will be described. FIG. 5 is a diagram showing the electric vehicle 1 and the replaceable battery supply base 7. As shown in FIG. Although the replaceable battery supply base 7 in FIG. 5 indicates a charging station, it may be a gas station, a parking area, a service area, a manufacturer's direct sales store, or a mass retailer of general car accessories.

At the replaceable battery supply base 7, the charged replaceable battery 6 is prepared to be supplied to the electric vehicle 1 requiring replacement. For example, the replaceable battery 6 is placed as a product (in stock) at the replaceable battery supply base 7 and supplied by the user purchasing it. When the charge amount of the replaceable battery 6 in use decreases, the user can appropriately acquire the charged replaceable battery 6 by moving the electric vehicle 1 to the replaceable battery supply base 7, or the like.
A user can take out the replaceable battery 6 whose charge amount has decreased due to the use of the electric vehicle 1 from the replaceable battery mounting part (421, 412, 22), replace it with a charged replaceable battery 6 obtained from the replaceable battery supply base 7, and use it. Note that the replacement work may be performed by a person other than the user.

The replaceable battery 6 may have a different power capacity for each power capacity required to drive the electric vehicle 1, as described above. For example, the replaceable battery 6 is configured to have a power capacity capable of supplying power to each of the drive motors 411 mounted on a large-sized vehicle, a medium-sized vehicle, or a small-sized vehicle. The replaceable batteries 6 with different standards for large, medium, and small vehicles have different battery bodies for large, medium, and small vehicles. Note that different battery bodies can be configured with battery cells having different numbers of battery cells.

The electric vehicle 1 according to the present embodiment has been described above.
The electric vehicle 1 is provided with replaceable battery mounting portions 421, 412, and 22 in at least one of the cargo compartment 42, the drive device storage chamber 41, or the floor side member 312 below the vehicle interior 43. The replaceable battery mounting portions 421, 412, and 22 are detachably mounted with replaceable batteries 6 that are charged in advance and can supply power to the drive motor 411 of the electric vehicle 1.
The replaceable battery 6 is commonly used in electric vehicles 1 manufactured by different manufacturers, and is composed of a plurality of types of battery bodies each having a power capacity corresponding to the power consumption of the driving motor 411 .

Depending on the user, the electric vehicle 1 may take a long charging time as a drawback. However, by making the replaceable battery 6 a common component and arranging it at a replaceable battery supply base 7 so that the user can replace it as needed, the time required for charging to continue driving the electric vehicle 1 can be reduced or omitted. Therefore, it is possible to eliminate the user's anxiety about power failure during driving, and to stably operate the electric vehicle 1, which is becoming a social infrastructure.

In addition, the replaceable battery 6 and the replaceable battery mounting portions 421, 412, and 22 are common cassette-type battery parts regardless of the manufacturer and vehicle type of the electric vehicle 1, so they can be mounted in a uniform manner regardless of each automobile manufacturer. Accordingly, the replaceable battery manufacturer manufactures a large number of replaceable batteries of a single standard and supplies them to the sales side, which in turn supplies them to the replaceable battery supply base.
As a result, since it is only necessary to prepare a single standard replaceable battery 6 at the replaceable battery supply base 7, there is no need to prepare replaceable batteries of each manufacturer's standard for each of a plurality of electric vehicle manufacturers, and the cumbersomeness of preparing a large number of each of a plurality of standard replaceable batteries can be avoided. In addition, it is possible to effectively reduce the situation where the replaceable battery 6 is out of stock. Therefore, the user can use the replaceable battery supply base 7 for the replaceable battery 6 with peace of mind.

In addition, the electric vehicle 1 is provided with the replaceable battery mounting portions 421, 412, and 22 at a plurality of locations on the vehicle body 2, and a plurality of the replaceable batteries 6 are mounted in a distributed manner, thereby ensuring the amount of electricity stored. By dispersing and mounting a plurality of replaceable batteries 6 in this manner, it is possible to improve the degree of freedom in layout of the replaceable battery mounting portion in the vehicle body 2 while ensuring power capacity.

In the present embodiment, an example in which one replaceable battery 6 can be attached to each of the replaceable battery attachment portions 421, 412, and 22 has been described. As a result, it is possible to increase the power capacity that can be supplied from one replaceable battery mounting portion.

In the present embodiment, an example in which the replaceable battery 6 and the replaceable battery mounting portions 421, 412, and 22 have different standards for each size of the electric vehicle 1 has been described.
Therefore, the replaceable battery 6 and the replaceable battery mounting portions 421, 412, and 22 can be used as common parts regardless of the size of the electric vehicle 1 (large vehicle, medium vehicle, or small vehicle). This further reduces the risk of the replaceable battery 6 being out of stock at the replaceable battery supply base 7 .

Since the invention of the present application relates to an electric vehicle in which a replaceable battery is detachably attached, it has wide industrial applicability.
