Title:
BATTERY RESISTANCE MEASURING DEVICE, VEHICLE, AND BATTERY RESISTANCE MEASURING METHOD
Document Type and Number:
Japanese Patent JP2022139807
Kind Code:
A
Abstract:
To provide a battery resistance measuring device, a vehicle, and a battery resistance measuring method capable of simply and accurately measuring the electric resistance of a battery.SOLUTION: A battery resistance measuring device that measures electrical resistance of a target battery includes a determination portion and a measurement portion. The determination portion is configured to determine whether the target battery has switched from a charging state to a discharging state in which power greater than supplied power is output while receiving the supplied power, on the basis of whether a predetermined condition is satisfied. The measurement portion is configured to start measuring the electrical resistance of the target battery at a timing when the determination unit determines that the target battery has switched from the charged state to the discharged state.SELECTED DRAWING: Figure 13
