To provide an automatic charging system of an autonomous mobile vehicle which can prevent an occurrence of overcharging and a charging shortage at a low cost even when charging of a secondary battery is quickly performed within a limited time.SOLUTION: An automatic charging system 100 has an unmanned carrier 120 moving in a predetermined route, and a quick charger 110 installed in a predetermined route and charing a secondary battery 121 mounted on the unmanned carrier 120. The quick charger 110 has a measurement portion 112 measuring a battery voltage of the secondary battery 121. The quick charger 110 does not charge the secondary battery 121 when the battery voltage is equal to or more than an upper-limit threshold voltage, and charges the secondary battery 121 by supplying a constant current to the secondary battery 121 according to the battery voltage for a predetermined time when the battery voltage is less than the upper-limit threshold voltage, so that a capacity (charge amount) supplied to the secondary battery 121 by the quick charger 110 at single charging is a value obtained by dividing the capacity of the secondary battery 121 by a predetermined value.SELECTED DRAWING: Figure 1

    【課題】限られた時間内に二次電池を急速に充電する場合であっても、過充電や充電不足の発生を低コストに防ぐことができる、自律移動車両の自動充電システムを提供する。【解決手段】所定の経路を移動する無人搬送車120と、所定の経路上に配置され、無人搬送車120に搭載された二次電池121を充電する急速充電器110と、を備え、急速充電器110は、二次電池121の電池電圧を測定する測定部112を備え、急速充電器110は、当該電池電圧が上限閾値電圧以上である場合、二次電池121を充電せず、当該電池電圧が上限閾値電圧未満である場合、二次電池121に当該電池電圧に応じた一定の電流をあらかじめ定められた時間供給することにより二次電池121を充電し、1回の充電において急速充電器110によって二次電池121に供給される容量(充電量)は、二次電池121の容量を所定の値で除した値である、自動充電システム100。【選択図】図1
