Abstract

A battery control system and a battery control program are provided which are capable of determining a residual value of a battery according to control contents of the battery and giving a user a return for the residual value.A battery control system includes: an electric motor vehicle 10 including a battery 40, a communication device 50, a battery control unit 36, and a display device 60; and a server device 300.

First claim

What is claimed is:

1 . A battery control system, comprising:
an electric motor vehicle including a battery, a communication device, a battery control unit, and a display device; and a server device, wherein the battery control unit performs charge/discharge control of the battery by restricting part of functions of the battery and removes restrictions on part of functions of the battery in response to an input of a restriction removal key; the display device displays information on the part of functions of the battery, the part being restricted by the battery control unit; and the server device includes: a reception unit receiving a restriction removal request, the restriction removal request being transmitted from the communication device; and a transmission unit transmitting the restriction removal key to the communication device.

2 . The battery control system according to claim 1 , wherein
the part of functions of the battery, the part being restricted by the battery control unit, includes an allowable traveling distance per unit period of the electric motor vehicle.

3 . The battery control system according to claim 1 , wherein
the electric motor vehicle further includes a power transmission device transmitting power to an outside, the power having been stored in the battery; and the part of functions of the battery, the part being restricted by the battery control unit, includes an amount of power transmitted per unit period by the power transmission device to the outside.

4 . A battery control program controlling a battery mounted on an electric motor vehicle, the battery control program causing execution of:
a registration step of registering a discharge capacity of the battery for each discharge purpose; an identification step of identifying a discharge purpose of the battery in discharging; an output step of outputting an allowable discharge capacity based on the registered discharge capacity of the battery for the each discharge purpose; and a discharge control step of outputting, when the discharge capacity is insufficient, a discharge control signal.
