International ClassB65G 067/02AbstractA battery transfer and charging system for electric vehicles includes a conveyor loop for conveying batteries from a battery receiving station to a battery delivery station. A displacement assembly removes spent batteries of electric vehicles by forcing charged batteries into position within the vehicles so as to laterally displace spent batteries. Spent batteries displaced from vehicles are received by the receiving station, where the batteries are tested both electrically and by comparing battery status data against predetermined criteria. Batteries which fail the battery test are automatically removed from the conveyor loop by a elevator assembly. Batteries are automatically charged as they pass through the conveyor loop in an assembly-line fashion. Following recharge, batteries are conveyed to the displacement station for installation within later vehicles. In one embodiment of the system, vehicles drive through the system in sequential order, stopping at a specified location for battery installation/removal.Field of SearchCooperating means comprises or includes a conveyorMeans is confined to one of the vehicles With means on each vehicle cooperating to effect, or facilitate, transfer of load WHEELED, LOAD-TRANSPORTING TYPE VEHICLES AND MEANS FOR TRANSFERRING, OR ENABLING TRANSFER OF, LOAD FROM ONE VEHICLE TO ANOTHER Of driven type, for unloading a wheeled vehicle Including load raising or lowering device Including load pushing or pulling device With control system responsive to changeable operating instructions With additional means for aligning vehicle and an external load support Having means for also moving load laterally With flexible, load-underlying element or surface Power-driven conveyor for loading a wheeled vehicle Raising or lowering device of driven type for loading a wheeled vehicle Pushing or pulling device for loading a wheeled vehicle by exerting a generally horizontal force on load Means serves to align wheeled vehicle and load receiving or relinquishing structure LOAD-TRANSPORTING TYPE VEHICLE TO BE LOADED OR UNLOADED, OR EXTERNAL MEANS FOR THE LOADING OR UNLOADING, OR FOR COOPERATING THEREWITH, OF SUCH A VEHICLE VEHICLE BATTERY REPLACER Battery mountings and holders Having means to read magnetically encoded check CHECK-OPERATED RELEASER FOR AUTOMOBILE SERVICE EQUIPMENT | |
