Abstract
A battery management support device that is configured to acquire information on an electric vehicle including a battery that is rechargeable with electric power received from an external power supply. The information includes at least information when the electric vehicle is parked indicating a temperature of the battery, information when the electric vehicle is parked indicating an electrical connection state between the electric vehicle and the external power supply, and information when the electric vehicle is parked indicating an operation state of a cooling device for the battery.
Claims8
A battery management support device that is configured to acquire information on an electric vehicle including a battery that is rechargeable with electric power received from an external power supply,
- wherein the information includes at least:
- information when the electric vehicle is parked indicating a temperature of the battery;
- information when the electric vehicle is parked indicating an electrical connection state between the electric vehicle and the external power supply;
- and
- information when the electric vehicle is parked indicating an operation state of a cooling device for the battery,
- wherein, when it is determined, based on the information, that there is influence on a performance guarantee of the battery, a guarantee guidance notice for offering information on the performance guarantee of the battery is issued to the user or the owner of the electric vehicle,
- wherein, the determining whether there is influence on the performance guarantee of the battery is based on a cumulative high-temperature period, which is a cumulative value of a high-temperature period in which the temperature of the battery is equal to or higher than a predetermined value, and
- wherein the guarantee guidance notice is issued at a first frequency when the cumulative high-temperature period is equal to or longer than a first threshold value that is a condition for determining that there is influence on the performance guarantee of the battery, and the guarantee guidance notice is issued at a second frequency higher than the first frequency when the cumulative high-temperature period exceeds the first threshold value and is equal to or longer than a second threshold value.
A battery management support method for supporting battery management in an electric vehicle including a battery that is rechargeable by electric power received from an external power supply, the method comprising:
- a step in which a predetermined notice is issued to a user or an owner of the electric vehicle in accordance with a determination result based on acquired information of the electric vehicle,
- wherein the information includes at least:
- information when the electric vehicle is parked indicating a temperature of the battery;
- information when the electric vehicle is parked indicating an electrical connection state between the electric vehicle and the external power supply;
- and
- information when the electric vehicle is parked indicating an operation state of a cooling device of the battery,
- wherein, in the step, when it is determined, based on the information, that there is influence on a performance guarantee of the battery, a guarantee guidance notice for offering information on the performance guarantee of the battery is issued,
- wherein, the determining whether there is influence on the performance guarantee of the battery is based on a cumulative high-temperature period, which is a cumulative value of a high-temperature period in which the temperature of the battery is equal to or higher than a predetermined value, and
- wherein the guarantee guidance notice is issued at a first frequency when the cumulative high-temperature period is equal to or longer than a first threshold value that is a condition for determining that there is influence on the performance guarantee of the battery, and the guarantee guidance notice is issued at a second frequency higher than the first frequency when the cumulative high-temperature period exceeds the first threshold value and is equal to or longer than a second threshold value.
