Abstract

The present invention includes an information acquirer ( 21 ) configured to acquire a property of a battery ( 22 ) installed in an electric vehicle ( 20 ) and transmit the property as battery property information and a battery identification device ( 100 ) configured to collect the battery property information transmitted by a plurality of electric vehicles, generate a battery model by modeling the property of the battery on the basis of the collected battery property information, create control information according to the property of the battery for controlling traveling of each electric vehicle on the basis of the generated battery model, and provide the control information suitable for each electric vehicle.

First claim

What is claimed is:

1. A battery identification system comprising:
an information acquirer configured to acquire a property of a battery installed in an electric vehicle and transmit the property as battery property information; and
a battery identification device configured to collect the battery property information transmitted by a plurality of electric vehicles, generate a battery model by modeling the property of the battery on the basis of the collected battery property information, create control information according to the property of the battery for controlling traveling of each electric vehicle on the basis of the generated battery model, and provide the control information suitable for each electric vehicle,
wherein the battery identification device comprises:
a controller configured to ascertain the property of the battery and instruct to generate the battery model and create the control information;
a model generator configured to generate the battery model on the basis of the collected battery property information;
a control information creator configured to create the control information suitable for the property of the battery on the basis of the battery model; and
a communicator configured to receive the battery property information transmitted by the electric vehicle and transmit the control information suitable for the electric vehicle.

2. The battery identification system according to claim 1 ,
wherein the battery property information comprises at least an electric current, a voltage, and a temperature of the battery,
wherein the model generator is configured to generate the battery model for receiving at least the electric current, the voltage, and the temperature as input information and outputting at least one of internal resistance, a capacity, and a state of charge (SOC)-open circuit voltage (OCV) curve of the battery as output information, and
wherein the control information creator is configured to create the control information using the output information of the battery model.

3. The battery identification system according to claim 2 ,
wherein the model generator is configured to generate the battery model for outputting at least one of a type, an SOC, and an output of the battery as presentation information, and
wherein the controller is configured to ascertain the property of the battery using the presentation information of the battery model.

4. The battery identification system according to claim 3 , wherein the controller is configured to cause the communicator to transmit information about the ascertained property of the battery in a case where the ascertained property of the battery is not suitable for controlling the traveling of the electric vehicle.

5. The battery identification system according to claim 1 , wherein the information acquirer comprises:
a battery detector configured to detect an electric current, a voltage, and a temperature of the battery; and
a communication device configured to transmit the electric current, the voltage, and the temperature that have been detected.

6. A battery identification method comprising:
acquiring, by an information acquirer, a property of a battery installed in an electric vehicle and transmitting the property as battery property information; and
collecting, by a battery identification device, the battery property information transmitted by information acquirers provided in a plurality of electric vehicles, generating a battery model by modeling the property of the battery on the basis of the collected battery property information, creating control information according to the property of the battery for controlling traveling of each electric vehicle on the basis of the generated battery model, and providing the control information suitable for each electric vehicle,
wherein the battery identification method comprises:
by the battery identification device, ascertaining the property of the battery and instructing to generate the battery model and create the control information;
generating, by the battery identification device, the battery model on the basis of the collected battery property information;
creating, by the battery identification device, the control information suitable for the property of the battery on the basis of the battery model; and
by the battery identification device, receiving the battery property information transmitted by the electric vehicle and transmitting the control information suitable for the electric vehicle.
