To make it possible to accurately estimate the ambient temperature of a battery, excluding the influence caused by the operation of a vehicle equipped with the battery.SOLUTION: A battery ambient temperature estimation device estimates the temperature around a battery 50 on the basis of a temperature detected by a temperature sensor 21a that is attached to a positive terminal 51 of the battery 50 and detects the temperature, and a value of current discharged when the battery 50 is detecting the temperature of the temperature sensor 21a, and a correction coefficient used for estimation immediately after the start of the operation is set on the basis of a temperature change of the temperature sensor 21a.SELECTED DRAWING: Figure 1

    【課題】 バッテリを搭載する車両の動作に起因する影響を除いて精度良くバッテリの周囲温度を推定することを可能とする。【解決手段】 バッテリ50の正極端子51に組み付けられて温度を検出する温度センサ21aが検出した温度及びバッテリ50が温度センサ21aの温度検出中に放電する電流値に基づいてバッテリ50の周囲の温度を推定する、バッテリの周囲温度推定装置であって、動作開始直後における推定に用いる補正係数を、温度センサ21aの温度変化に基づき設定する。【選択図】 図1
