Abstract
Disclosed is a work vehicle management system including: a battery work information generation unit that generates battery work information indicating a use state of a battery during work of a work vehicle; a battery deterioration information generation unit that chronologically diagnoses the battery work information to generate battery deterioration information that indicates a deterioration trend of the battery that is unique to the work vehicle; and a notification unit that performs notification of the battery deterioration information to a manager of the work vehicle.
Claims7
A work vehicle management system for managing a work vehicle configured to perform work using a battery as a driving source, comprising:
- a satellite positioning module configured to detect position information associated with a position of the work vehicle;
- a vehicle position calculation unit configured to determine a location of a work site where the work is carried out and a work date and time based on the position information;
- a battery work information generation unit configured to generate battery work information that indicates a use state of the battery during the work of the work vehicle, wherein the battery work information includes the location of the work site where the work is carried out, the work date and time of the work, and a work load level of the work;
- a battery deterioration information generation unit configured to chronologically diagnose the battery work information to generate battery deterioration information that indicates a deterioration trend of the battery that is unique to the work vehicle;
- and
- a notification unit configured to perform notification of the battery deterioration information to a manager of the work vehicle,
- wherein a recommended work load level recommended for use of the battery is added as attribute information of the battery deterioration information,
- wherein the battery work information includes a location of a work site where the work is carried out, a work date and time of the work, and a work load level of the work,
- wherein a recommended work load level recommended for use of the battery is added as attribute information of the battery deterioration information, and
- wherein an environment state including weather of the work site, derived from the location of the work site where the work is carried out and the work date and time of the work, is added as attribute information of the battery deterioration information.
A work vehicle comprising:
- a first inverter current detector configured to detect a current of a travel motor inverter;
- a second inverter current detector configured to detect the current of a work motor inverter;
- a battery serving as a driving source for work of the work vehicle;
- a battery work information generation unit configured to generate battery work information indicating a use state of the battery during the work;
- a battery deterioration information generation unit configured to chronologically diagnose the battery work information to generate battery deterioration information that indicates a deterioration trend of the battery that is unique to the work vehicle;
- and
- a notification unit configured to perform notification of the battery deterioration information,
- wherein the battery work information includes a location of a work site where the work is carried out, a work date and time of the work, a work load level of the work, and an inverter electric power generated by the travel motor inverter and the work motor inverter,
- wherein a recommended work load level recommended for use of the battery is added as attribute information of the battery deterioration information, and
- wherein an environment state including weather of the work site, derived from the location of the work site where the work is carried out and the work date and time of the work, is added as attribute information of the battery deterioration information.
