Abstract

The present invention is to provide a charge/discharge control system and a charge/discharge control method capable of performing, in real time, highly accurate analysis of an internal state of a battery that is actually operating in a vehicle, and capable of performing control on the battery with a high accuracy based on the analysis, for improvement of safety. A battery charge/discharge control system 1 includes: an image acquirer 10 arranged in an inside of a battery 100 configured as a liquid battery, and configured to capture an image of the inside of the battery 100 ; a transferer 30 configured to transfer data of the image captured by the image acquirer 10 and a control signal; and controllers 14 and 50 configured to perform charge/discharge control on the battery based on the data of the image transferred from the transferer 30.

Claims (37)

1 . A battery charge/discharge control system comprising:

an image acquirer arranged in an inside of a battery configured as an all-solid battery, the image acquirer being configured to capture an image of the inside of the battery;

a transferer configured to transfer data of the image captured by the image acquirer and a control signal; and

a controller configured to perform charge/discharge control on the battery based on the data of the image transferred from the transferer,

the controller includes an inside-battery controller arranged in the inside of the battery and an outside-battery controller arranged outside the battery, and

the transferer transfers, by wireless communication, the data of the image captured by the image acquirer to the outside of the battery, the outside-battery controller transfers, by wireless communication, the control signal indicating a result of a determination based on the data of the image to the inside of the battery using the transferer, and the inside-battery controller performs, in response to reception of the control signal, charge/discharge control on the battery based on the control signal.

2 . A battery charge/discharge control system comprising:

an image acquirer arranged in an inside of a battery configured as a liquid battery, the image acquirer being configured to capture an image of the inside of the battery;

a transferer configured to transfer data of the image captured by the image acquirer and a control signal; and

a controller configured to perform charge/discharge control in the battery based on the data of the Image transferred from the transferer,

the controller includes an inside-battery controller arranged in the inside of the battery and an outside-battery controller arranged outside the battery, and

the transferer transfers, by wireless communication, the data of the image captured by the image acquirer to the outside of the battery, the outside-battery controller transfers, by wireless communication, the control signal indicating a result of a determination based on the data of the image to the inside of the battery using the transferer, and the inside-battery controller performs, in response to reception of the control signal, charge/discharge control on the battery based on the control signal.

3 . The battery charge/discharge control system according to claim 2 , wherein

the image acquirer and the transferer are isolated, by an isolation member that has resistance to an electrolytic solution forming part of the battery and that is capable of transmitting transmission radio waves, from the electrolytic solution in the inside of the battery.

4 . The charge/discharge control system according to claim 3 , wherein

the image acquirer comprises a light source and an image sensor, and

the light source and the image sensor are covered with a part of the isolation member, the part being capable of transmitting transmission radio waves.

5 . The battery charge/discharge control system according to claim 4 , wherein

an entirety of the isolation member is covered with thin film laminate, and

the part capable of transmitting transmission radio waves includes one of polyethylene, modified polyethylene, polypropylene, modified polypropylene and an ionomer; and

the isolation member includes a connection part that is electrically connected to the battery, the connection part being connected by heat welding and having a structure capable of preventing intrusion of the electrolytic solution to the light source and image sensor side in an inside of the isolation member.

6 . The battery charge/discharge control system according to claim 1 , wherein

power is supplied from the battery to the image acquirer, the transferer and the controller.

7 . The battery charge/discharge control system according to claim 1 , wherein

the transferer comprises an inside-battery transceiver arranged in the inside of the battery,

the battery comprises a casing having a thick part and a thin part, and

the inside-battery transceiver is arranged near the thin part.

8 . A battery charge/discharge control method comprising:

capturing an image of an inside of a battery;

transferring data of the captured image;

making determination as to a state of the battery based on the data of the image in real time and transferring a control signal indicating a result of the determination; and

performing charge/discharge control on the battery based on the control signal,

during the transferring data of the captured image, an inside-battery controller arranged in the inside of the battery performs a control to transfer, by wireless communication, the data of the image captured by the image acquirer to the outside of the battery,

during the transferring of the control signal indicating the result of the determination, an outside-battery controller arranged outside the battery performs a control to transfer, by wireless communication and to the inside of the battery, the control signal indicating the result of the determination based on the data of the image,

during the performing charge/discharge control on the battery, the inside-battery controller performs, in response to reception of the control signal, charge/discharge control on the battery based on the control signal.

9 . The battery charge/discharge control method according to claim 8 , wherein

the determination is made by an ECU of a vehicle.
