To provide a charge management system which can constantly brake an electric vehicle by regenerating the motion energy of the electric vehicle.SOLUTION: A charge management system comprises: a navigation device which can extract all travelable traveling routes within a range of a preset traveling distance from a current place, and can extract a gradient of the traveling route or an altitude difference at each zone which is partitioned by a preset distance; and a charge management device including a power amount derivation part which can derive a power consumption amount or a power regeneration amount at each zone on the basis of the gradient or the altitude difference which is extracted by the navigation device, an income/expenditure calculation part which can calculate an income and an expenditure of a power amount from the current place on the basis of the power consumption amount or the power regeneration amount which is derived by the power amount derivation part, and a power amount decision part for deciding a power amount of a drive battery at a finish of external charge so that the power amount at each of all the zones at which the income/expenditure of the power amount calculated by the income/expenditure calculation part becomes a plus side reaches a maximum value of the power amount which is chargeable to the drive battery or smaller.SELECTED DRAWING: Figure 1
【課題】電動車両の運動エネルギーを回生することによる電動車両の制動を常時可能とする充電管理システムを提供する。【解決手段】充電管理システムは、現在地から予め設定された走行距離の範囲内で走行可能な走行経路を全て抽出可能であって、走行経路の勾配又は標高差を予め設定された距離によって区切られた区間毎に抽出可能なナビゲーション装置と、ナビゲーション装置によって抽出された勾配又は標高差に基づいて区間毎に電力消費量又は電力回生量を導出可能な電力量導出部と、電力量導出部によって導出された電力消費量又は電力回生量に基づいて現在地からの電力量の収支を区間毎に算出可能な収支演算部と、収支演算部によって算出された電力量の収支がプラスになる全ての区間毎の電力量が駆動用バッテリに充電可能な電力量の最大値又はそれ以下となるように、外部充電終了時の駆動用バッテリの電力量を決定する電力量決定部とを含む充電管理装置とを備える。【選択図】 図1
