Abstract

A battery state display system includes: a plurality of electric vehicles, each of the plurality of electric vehicles being configured to be driven by a battery containing battery fluid; and a display terminal. The display terminal includes: a communication unit configured to communicate with the plurality of electric vehicles; a display configured to display an image including a state of the battery of each of a plurality of electric vehicles on the display of the display terminal; and a processor configured to: control the display terminal to display on the display a battery state indication for each of the electric vehicles, the battery state indication including: a charge state indication representing a charge state of the battery; and a fluid amount indication relating to an amount of the battery fluid of the battery.

Claims

1. A battery state display system comprising:

a plurality of electric vehicles, each of the plurality of electric vehicles being configured to be driven by a battery containing battery fluid; and

a display terminal comprising;

a communication unit configured to communicate with the plurality of electric vehicles;

a display configured to display an image including a state of the battery of each of a plurality of electric vehicles on the display of the display terminal; and

,

a processor configured to;

control the display terminal to display on the display a battery state indication for each of the electric vehicles, the battery state indication including;

a charge state indication representing a charge state of the battery; and

a fluid amount indication relating to an amount of the battery fluid of the battery.

2. The battery state display system according to claim 1, wherein

each of the electric vehicles includes:

a SOC information acquisition unit configured to acquire SOC information relating to the charge state of the electric vehicle; and

a radio transmission unit configured to transmit the SOC information by radio communication, and

the communication unit of the display terminal receives the SOC information, and

the processor of the display terminal displays the charge state indication based on the received SOC information.

3. The battery state display system according to claim 2, wherein

the controller of the display terminal is configured to acquire, for each of the electric vehicles, fluid amount information relating to the amount of battery fluid, and

display the fluid amount indication based on the fluid amount information.

4. The battery state display system according to claim 3, wherein

the processor is configured to acquire necessity/unnecessity information representing replenishment necessity or replenishment unnecessity of the battery fluid as the fluid amount information, and

display, based on the necessity/unnecessity information, a fluid replenishment necessity indication representing the replenishment necessity of the battery fluid or a fluid replenishment unnecessity indication representing the replenishment unnecessity of the battery fluid, as the fluid amount indication, for each of the electric vehicles.

5. The battery state display system according to claim 4, wherein

the processor is configured to set the necessity/unnecessity information to the replenishment necessity in a case that a predetermined first time period elapses after date/time at which the battery fluid is replenished most recently as to the electric vehicle, and set the necessity/unnecessity information to the replenishment unnecessity in a case that the predetermined first time period does elapse yet.

6. The battery state display system according to claim 3, wherein

the processor is configured to:

acquire level information representing an amount of the battery fluid as the fluid amount information, for each of the electric vehicles, and

display, based on the level information, a fluid amount level indication representing a level of an amount of the battery fluid as the fluid amount indication, for each of the electric vehicles.

7. A display terminal comprising:

a communication unit configured to communicate with a plurality of electric vehicles, each of the plurality of electric vehicles being configured to be driven by a battery containing battery fluid;

a display configured to display an image including a state of the battery of each of a plurality of electric vehicles on the display of the display terminal; and

a processor configured to;

control the display terminal to display on the display a battery state indication for each of the electric vehicles, the battery state indication including;

a charge state indication representing a charge state of the battery; and

a fluid amount indication relating to an amount of the battery fluid of the battery.

8. The display terminal according to claim 7, wherein

each of the electric vehicles includes:

a SOC information acquisition unit configured to acquire SOC information relating to the charge state of the electric vehicle; and

a radio transmission unit configured to transmit the SOC information by radio communication, and

the communication unit of the display terminal receives the SOC information, and

the processor of the display terminal displays the charge state indication based on the received SOC information.

9. The display terminal according to claim 8, wherein

the controller of the display terminal is configured to:

acquire, for each of the electric vehicles, fluid amount information relating to the amount of battery fluid, and

display the fluid amount indication based on the fluid amount information.

10. The display terminal according to claim 9, wherein

the processor is configured to

acquire necessity/unnecessity information representing replenishment necessity or replenishment unnecessity of the battery fluid as the fluid amount information, and

display, based on the necessity/unnecessity information, a fluid replenishment necessity indication representing the replenishment necessity of the battery fluid or a fluid replenishment unnecessity indication representing the replenishment unnecessity of the battery fluid, as the fluid amount indication, for each of the electric vehicles.

11. The display terminal according to claim 10, wherein

the processor is configured to set the necessity/unnecessity information to the replenishment necessity in a case that a predetermined first time period elapses after date/time at which the battery fluid is replenished most recently as to the electric vehicle, and set the necessity/unnecessity information to the replenishment unnecessity in a case that the predetermined first time period does elapse yet.

12. The display terminal according to claim 9, wherein

the processor is configured to:

acquire level information representing an amount of the battery fluid as the fluid amount information, for each of the electric vehicles, and

display, based on the level information, a fluid amount level indication representing a level of an amount of the battery fluid as the fluid amount indication, for each of the electric vehicles.
