PROBLEM TO BE SOLVED: To provide a battery charging rate estimation device capable of displaying a battery charging rate at the timing of the arrival of a vehicle at estimated predetermined charging facilities without user's setting a travel route from a current vehicle position to the position of the predetermined charging facilities.SOLUTION: Provided is a battery charging rate estimation device comprising: storage means storing position information on charging facilities; acquisition means acquiring a charging rate of a battery mounted in a vehicle; position detection means detecting a position of the vehicle; automatic setting means automatically setting estimation-target charging facilities as intended charging facilities; travel-route calculation means calculating a travel route from a current position of the vehicle to the intended charging facilities based on the position information on the charging facility and the position of the vehicle; electric-energy calculation means calculating electric energy consumed by the battery as a result of vehicle traveling on the travel route on the basis of an energy consumption rate at a time of the vehicle travel and the travel route; charging-rate estimation means estimating a charging rate at timing of arrival of the vehicle at the intended charging facilities based on the charging rate and the electric energy at the current position of the vehicle; and guidance means providing a guidance of the charging rate estimated by the charging-rate estimation means.

    【課題】ユーザが現在の車両の位置から所定の充電施設の位置までの走行経路を設定せずに、推定した所定の充電施設に到達した時点おけるバッテリの充電率を表示するバッテリの充電率推定装置を提供する。【解決手段】充電施設の位置情報を記憶する記憶手段と、車両に搭載されたバッテリの充電率を取得する取得手段と、車両の位置を検出する位置検出手段と、推定の対象となる充電施設を対象充電施設として自動で設定する自動設定手段と、充電施設の位置情報と車両の位置に基づいて、車両の現在位置から対象充電施設までの走行経路を算出する走行経路算出手段と、車両の走行時におけるエネルギー消費率と走行経路に基づいて、車両が走行経路を走行することにより、バッテリの消費する電力量を算出する電力量算出手段と、車両の現在位置における充電率と電力量に基づいて、対象充電施設に車両が到達した時点の充電率を推定する充電率推定手段と、充電率推定手段により推定された充電率を案内する案内手段を備えるバッテリの充電率推定装置を提供する。【選択図】 図1
