An in-vehicle battery management device includes a controller configured or programmed to control a charge/discharge device such that the charge/discharge device performs charge or discharge on an in-vehicle battery of an electric vehicle in a predetermined processing condition, the in-vehicle battery being connected to the charge/discharge device. The controller includes a calculator configured or programmed to calculate a degree of deterioration progress of the in-vehicle battery based on charge/discharge information in the charge or discharge; and a communicator configured or programmed to notify a predetermined notification target of the calculated degree of deterioration progress.

In-vehicle battery management device

An electric power adjusting device is configured to execute a process of acquiring vehicle information of a plurality of electric vehicles connected to a power utility grid, a process of classifying, based on the vehicle information, the electric vehicles into a plurality of groups according to predetermined characteristics, and a process of adjusting a charging and discharging burden on the electric vehicles fir each of the groups when adjusting an electric power demand in the power utility grid.

Electric power adjusting device

An guidance system of an electric mobility vehicle includes a registration section in which replacement places of replacement batteries for the electric mobility vehicle are registered, an estimation section that estimates a possible travel distance of the electric mobility vehicle from a battery remaining capacity of the electric mobility vehicle, and a display section that displays replacement places within a range of the estimated possible travel distance of the electric mobility vehicle among the replacement places of the replacement batteries registered in the registration section on map information.

Guidance system of electric mobility vehicle

A charging and discharging control device disclosed herein controls a charging and discharging device that charges and discharges an on-vehicle battery mounted on an electric vehicle. The charging and discharging control device includes a detection controller configured or programmed to detect that the electric vehicle has been connected to the charging and discharging device, an SOC acquisition controller configured or programmed to acquire an SOC of the on-vehicle battery, a use information acquisition controller configured or programmed to acquire a next use time and a next travel distance of the electric vehicle, and a setting controller configured or programmed to set a charging and discharging schedule of the on-vehicle battery such that the on-vehicle battery is charged after having been maintained in a low SOC and a necessary SOC for the next use time and the next travel distance remains.
