To provide a forklift battery charging control device capable of, when controlling charging of a battery of an electric forklift, properly determining the degree of consumption of the battery in view of the most important function of the electric forklift of lifting a load with a fork.SOLUTION: A forklift battery charging control device includes a control unit 12 that controls charging of a battery 6 of an electric forklift 1. The control unit 12 causes a storage unit 11 to store the minimum fork load voltage Vmin of a fork load voltage measured by a voltage sensor 10 while operation of a fork 8 is being detected by a fork operation sensor 9, causes a charging on/off unit 7 to electrically disconnect a charging cable 3 from the battery 6 when the minimum fork load voltage Vmin is equal to or higher than a prescribed voltage Vx, and allows the charging on/off unit 7 to establish electrical connection between the charging cable 3 and the battery 6 when the minimum fork load voltage Vmin is lower than the prescribed voltage Vx.SELECTED DRAWING: Figure 3

    【課題】電動式のフォークリフトのバッテリーの充電を制御する際、フォークで荷物を持ち上げるという電動式フォークリフトの最も重要な機能を考慮してバッテリーの消耗度合いを的確に判断できるフォークリフトのバッテリー充電制御装置を提供する。【解決手段】電動式のフォークリフト1のバッテリー6の充電を制御する制御部12を備えており、制御部12は、フォーク作動センサ9がフォーク8の作動を検出しているとき電圧センサ10で測定したフォーク負荷電圧のうち最小フォーク負荷電圧Vminを記憶部11に記憶させ、最小フォーク負荷電圧Vminが所定電圧Vx以上の場合に充電オンオフ部7によって充電ケーブル3とバッテリー6とを電気的に切り離し、最小フォーク負荷電圧Vminが所定電圧Vx未満の場合に充電オンオフ部7による充電ケーブル3とバッテリー6との電気的な接続を許容する。【選択図】図3
