To provide a technique for estimating the charging rate of a battery with a simple configuration.SOLUTION: An estimation device for estimating a charging rate of a battery that supplies power to auxiliary equipment mounted on a vehicle, includes: a voltage sensor to detect battery voltage; a temperature sensor to detect battery temperature; and a processing circuit connected to the pressure sensor and the temperature sensor and performing an estimation process to estimate the charging rate of the battery. The estimation process is executed while the vehicle is parked, and estimates the charging rate of the battery based on a detected voltage detected by the voltage sensor and a detected voltage detected by the temperature sensor.SELECTED DRAWING: Figure 2
【課題】バッテリの充電率を簡素な構成で推定するための技術を提供する。【解決手段】車両に搭載される補機に電力を供給するバッテリの充電率を推定する推定装置は、バッテリの電圧を検出する電圧センサと、バッテリの温度を検出する温度センサと、電圧センサ及び温度センサに接続されており、バッテリの充電率を推定する推定処理を実行する処理回路と、を備える。推定処理は、車両の駐車中に実行され、電圧センサによって検出される検出電圧と、温度センサによって検出される検出電圧とに基づいて、バッテリの充電率を推定する。【選択図】図2
