Description
を用いた測距センサでもよい。
この場合、蓄電モジュールを急速充電しても、冷却装置によって蓄電モジュールが冷却されるので、急速充電による蓄電ユニットの高温化を抑制でき、急速充電による蓄電モジュールの劣化を抑制することができる。
この場合、蓄電ユニットが電動式搬送車両に装着された状態では、充電用端子が電動式搬送車両の外側を臨むため、充電用端子は外部電源と接続し易くなる。よって、蓄電ユニットが電動式搬送車両に装着された状態での蓄電モジュールの充電が行い易い。
この場合、冷却装置は電動式搬送車両の運転時に蓄電モジュールを冷却することができる。よって、蓄電モジュールの放電時における高温化を抑制でき、放電による蓄電モジュールの劣化を抑制することができる。
(1)蓄電ユニット25は、外部電源の出力端子Tと接続可能な充電用端子29と、充電用端子29と蓄電モジュール27との間の通電と、蓄電モジュール27と給電用端子28との間の通電を切り換える切換スイッチ30と、切換スイッチ30を制御する制御装置31と、を備える。このため、コンテナ用無人搬送車10から取り外された蓄電ユニット25を充電することができるほか、コンテナ用無人搬送車10に装着された蓄電ユニット25を充電することができる。したがって、蓄電ユニット25の充電待ち等によるコンテナ用無人搬送車10の搬送効率の低下を抑制することができる。また、蓄電モジュール27が故障してコンテナ用無人搬送車10が停止しても、故障した蓄電ユニット25と充電済みの蓄電モジュール27を備えた蓄電ユニット25とを入れ換えて交換すれば、停止したコンテナ用無人搬送車10を牽引する作業が大幅に削減され、コンテナ用無人搬送車10の保守作業の効率が向上する。
○ 上記の実施形態では、蓄電モジュールの蓄電池はリチウムイオン二次電池としたが、蓄電モジュールの蓄電池はリチウムイオン二次電池に限定されない。蓄電モジュールの蓄電池は、例えば、ニッケル水素二次電池等、リチウムイオン二次電池以外の二次電池としてもよい。
○ 上記の実施形態では、蓄電モジュール毎に冷却装置を設けたがこの限りではない。冷却装置の数は特に限定されない。また、送風ファンによる空冷式の冷却装置としたが、ラジエータおよびラジエータファンを用いる水冷式の冷却装置であってもよい。
○ 上記の実施形態では、冷却装置は急速充電時および走行時に蓄電モジュールを冷却するとしたが、冷却装置は急速充電時のみ冷却するようにしてもよい。また、走行時に冷却する場合でも、放電に応じて冷却装置の送風量を増減するようにしてもよい。
○ 上記の実施形態では、蓄電ユニット装置が適用される電動式搬送車両としてコンテナ用無人搬送車を例示して説明したが、電動式搬送車両は、コンテナ用無人搬送システムに限定されない。例えば、有人式の電動式搬送車両でもよく、搬送対象の荷もコンテナ以外の荷であってもよい。
