Abstract
In a vehicle usage status estimation system, a data acquisition unit acquires, while a battery pack currently or previously mounted on an electric vehicle is connected to a charging apparatus, time-series battery data covering a period during which the electric vehicle is used from the battery pack via the charging apparatus. An SOC transition identification unit identifies a transition of SOC (State Of Charge) of the battery pack since completion of previous charging of the battery pack used in the electric vehicle, based on the time-series battery data. A running status estimation unit estimates a running status at a time of use of the electric vehicle by referring to the transition of SOC.
Claims6
A vehicle usage status estimation system comprising:
- a data acquisition unit that acquires, while a battery pack currently or previously mounted on an electric vehicle is connected to a charging apparatus, time-series battery data covering a period during which the electric vehicle is used from the battery pack via the charging apparatus;
- an SOC transition identification unit that identifies a transition of SOC (State Of Charge) of the battery pack since completion of previous charging of the battery pack used in the electric vehicle, based on the time-series battery data;
- and
- a running status estimation unit that estimates a running status at a time of use of the electric vehicle by referring to the transition of SOC.
A vehicle usage status estimation method comprising:
- acquiring, while a battery pack currently or previously mounted on an electric vehicle is connected to a charging apparatus, time-series battery data covering a period during which the electric vehicle is used from the battery pack via the charging apparatus;
- identifying a transition of SOC (State Of Charge) of the battery pack since completion of previous charging of the battery pack used in the electric vehicle, based on the time-series battery data;
- and
- estimating a running status at a time of use of the electric vehicle by referring to the transition of SOC.
A non-transitory computer-readable recording medium having embodied thereon a vehicle usage status estimation program comprising computer-implemented modules including:
- a module that acquires, while a battery pack currently or previously mounted on an electric vehicle is connected to a charging apparatus, time-series battery data covering a period during which the electric vehicle is used from the battery pack via the charging apparatus;
- a module that identifies a transition of SOC (State Of Charge) of the battery pack since completion of previous charging of the battery pack used in the electric vehicle, based on the time-series battery data;
- and
- a module that estimates a running status at a time of use of the electric vehicle by referring to the transition of SOC.
