Abstract: A fluid regulating system is provided for controlling fluid to a fluid consuming battery having a fluid consuming cell. The fluid regulating system includes a valve having a moving plate disposed adjacent to a fixed plate, and both having fluid entry ports to open and close a valve. The fluid regulating system also includes an actuator for moving the moving plate to open and close the valve. The actuator is controlled to open the valve when greater battery electrical output is required to operate a device and maintains the valve in the open position for a minimum required time to minimize battery capacity loss due to operation of the fluid regulating system.

Abstract: Disclosed herein is a cooling system for a battery pack that is usable as a power source of electric vehicles and hybrid-electric vehicles. The cooling system has the effect of effectively dissipating heat generated from battery cells by supplying a refrigerant to the battery cells at a constant flow rate, and of minimizing a temperature difference between the battery cells during a cooling process. This prevents degradation in the performance of the battery cells, and achieves optimal temperature control. Also, the cooling system employs a single refrigerant guide member arranged at a side of the battery pack, resulting in a reduction in the size of an overall battery system.

Abstract: A series of cell fill valves are interconnected by tubing and T-connections, one to each battery cell. Each cell fill valve is controlled by a ball in a seat in a single fill opening. The ball is controlled by a float on a pivotable lever arm with an end finger which holds the ball up to admit water with the float down and allows the ball to lower onto the seat as the cell fills causing the float to rise to a shutoff level when the cell is filled to a desired level.

Abstract: A fluid consuming battery (10) is provided with a fluid regulating system (50) for regulating fluid entry into the battery. The battery (10) includes a fluid consuming cell (20) having a cell housing with fluid entry ports for the passage of a fluid into the cell housing. A first fluid consuming electrode and a second electrode are disposed within the cell housing. The fluid regulating system (50) includes a valve having a moving plate (66) disposed adjacent to a fixed plate (62). The moving plate and fixed plate both have fluid entry ports (68, 64) that align in an open valve position and are misaligned in a closed valve position. The fluid regulating system (50) also includes an actuator that may include one or more shape memory alloy (SMA) components (82a, 82b) for moving the moving plate (66) relative to the fixed plate (62) to open and close the valve.

Abstract: Disclosed herein is a prismatic battery having an electrode assembly mounted in a prismatic battery case, wherein an electrolyte injection hole formed in a base plate mounted to an open upper end of the battery case is constructed such that an inside upper end of the electrolyte injection hole is formed in a downward taper (incline) structure, and a metal ball is forcibly inserted into the electrolyte injection hole such that the metal ball is plastically deformed to seal the electrolyte injection hole. The prismatic battery according to the present invention provides high coupling force between the metal ball and the electrolyte injection hole due to the plastic deformation and forced insertion of the metal ball and high sealability of the electrolyte injection hole. Also, the formation of a groove at the upper end of the forcibly inserted metal ball and the generation of cracks at the interface between the metal ball and the inside surface of the electrolyte injection hole are effectively prevented.
