A method for inspecting an energy storage device, the method includes: estimating a degree of degradation of the energy storage device; determining, based on the estimated degree of degradation, a measurement condition such that time required to measure a full charge capacity of the energy storage device decreases or increases; and measuring the full charge capacity according to the determined measurement condition.

Method for inspecting energy storage device, non-transitory storage medium, and computer device

An estimation system includes a power storage device and one or more processors. The one or more processors are configured to execute a charge process of controlling a charge device so as to charge the power storage device, and an estimation process of estimating a full charge capacity of the power storage device. The one or more processors are configured to execute the charge process with an upper limit state of charge of the power storage device set to a value that is more than a first upper limit state of charge when a predetermined condition is met, the first upper limit state of charge being the upper limit state of charge at the time when the predetermined condition is not met.

Estimation system, estimation method, and vehicle

A battery control device includes a processor that is configured to estimate a full charge capacity of a battery based on an amount of current supplied to the battery from a start of charging to an end of charging and voltages of the battery at the start of charging and the end of charging when the battery is charged from a state where a voltage of the battery is below a predetermined start voltage threshold value to a state where the voltage exceeds a predetermined end voltage threshold value, and the battery satisfies a predetermined permission condition.

Battery control device

The control device includes an acquisition unit that acquires a first index value that is an index of a deterioration state of the power storage device, and a lower limit setting unit that lowers a lower limit value of an allowable range for a second index value indicating a power storage state of the power storage device, when the first index value acquired by the acquisition unit indicates a predetermined degree of deterioration or more.

Control device or control method

A flue gas detection system includes: a temperature sensor configured to detect a temperature in a duct; a temperature sensor configured to detect a temperature in a duct; and an ECU. The ECU is configured to determine that a high-temperature gas is released from an assembled battery, when a period during which a temperature increase amount in the duct is more than a reference amount and a period during which a temperature increase amount in the duct is more than a reference amount are included in a predetermined period.

Flue gas detection system and flue gas detection method

A route information transmission system, method and medium that acquire information for transferring a first travel route, on which a terminal device provides guidance, to an in-vehicle device as a second travel route on the basis of information pertaining to the first travel route, and transmit the acquired information.
