A battery charging rack has a cabinet 10 with a plurality of closeable bays 11 each arranged to receive one or more rechargeable batteries 2, and charging means coupleable to one or more batteries 2 in each bay 11. Each bay 11 has a door 16 which seals against a door frame 17 when closed. Any gas build up during charging is removed via a ventilation passage 12 linked to ducts 14 through an exterior wall 1 of a building, and a ventilation fan may be turned on by a gas sensor and/or when a liquid spill is sensed by a detector 15. Each door 16 may be hinged along a lower edge so as to form a horizontal platform when open as an aid to battery loading/unloading. Alternatively, each door may be hinged at a vertical side edge and may have a battery receiving tray (162, Figs.4,5) fixed to it. Each door 16 may also have an interlock switch such that power is only supplied to a battery when the door is closed. A coin release mechanism may be associated with each bay (Fig.3). A battery charging control unit (182, Fig.5) may control charging in response to a payment mechanism. |
