Abstract
A battery charging system includes a highrise storage rack system for holding a plurality of battery chargers and defining a plurality of battery locations. Each battery to be charged is placed on a pallet which has a connection block with a cable connectable to the battery and a male connector. A load carrier carries the pallet and the battery to a selected battery location in the rack and deposits it thereat in a charging position, thereby connecting the male connector to a female connector on the rack connected to one of the chargers. The load carrier also retrieves charged batteries on their pallets from the rack, the retrieval motion effecting disconnection of the pallet from the charger. Each pallet has a fluid receiving trough provided with a drain which cooperates with fluid inlets of a fluid collection system on the rack for collecting fluids emitted during the charging process.
