Abstract:
The present invention provides a liquid injection apparatus for injecting liquid into a container, comprising an injection chamber, a container for a liquid to be injected and entirely sealed except an injection port is placed in the injection chamber with the injection port directed to the bottom, an injection cell comprising at least one unit injection cell to accommodate the liquid to be injected is installed in the injection chamber, there is provided pressure regulating means to reduce the pressure in the injection chamber and to regulate pressure in the injection chamber to the atmospheric pressure or to a level higher than the atmospheric pressure, the pressure in the injection chamber is reduced to a level lower than the atmospheric pressure by the pressure regulating means at least once, and then, by maintaining the atmospheric pressure or the pressure higher than the atmospheric pressure, the liquid is injected through the injection port.
Abstract:
The invention relates to a battery which, for maintenance or in a danger situation, can be simply and reliably transferred from an operative state into a safe, inoperative state, whilst avoiding a short circuit. This is either brought about in that a controlled operable draining device for the rapid draining of the electrolyte is provided and that following the draining of the electrolyte all power-generating processes are stopped. Alternatively a battery with such characteristics is created in that in the danger situation a line introduces a deactivating substance into the electrolyte, which stops all power-generating, electrolytic processes.
Abstract:
A spill and leak containment system for a liquid electrolyte battery such as a zinc-bromine battery. The system includes one-piece, electrolyte reservoirs with pump mountings and other openings positioned at or near the tops of each reservoir. Positioning the openings at the tops of the reservoirs reduces the amount of electrolyte that might spill out of them, in the event of a leak or breach in the seal between the opening and the component mounted therein. The pump openings are surrounded by sumps, which will catch and contain liquid if there is a leak. To help contain vapor leaks, the invention also includes a vapor recovery system coupled to reservoir when it is filled with or emptied of electrolyte. The vapor recovery system allows for an exchange of vapors to occur between an electrolyte container and the battery reservoir while electrolyte fluid is being transferred. This prevents electrolyte vapor from escaping into the atmosphere where it might be potentially harmful to personnel setting up the system. A pressure equalization system is also provided in order to equalize the pressure between the anolyte and catholyte reservoirs.
Abstract:
A filling pod, a vehicle and a method for supplying fluid to a battery. The filling pod includes a filling pod housing having a filling pod port fluidly connectable to a fluid source for receiving fluid from the fluid source, a first fluid supply member fluidly connectable to a first cell and for supplying fluid from the filling pod port to the first cell, a second fluid supply member fluidly connectable to a second cell and for supplying fluid from the filling pod port and to the second cell, and an integral channel in fluid communication between the filling pod port, the first fluid supply member and the second fluid supply member. The channel includes a first channel portion in fluid communication between the filling pod port and the first fluid supply member and a second channel portion in fluid communication between the filling pod port and the second fluid supply member. When fluid is supplied to the filling pod through the filling pod port, a first amount of fluid flows through the first channel portion to the first fluid supply member and to the first cell, and a second amount of fluid flows through the second channel portion to the second fluid supply member and to the second cell.
Abstract:
A fixture, for liquid electrolyte impregnation of an electrochemical cell, includes a base on which a cap is removably provided. The base includes a nest that receives the electrochemical cell. The cap includes a fill port in communication with the nest. In order to impregnate the cell, a vacuum is created in the nest via the fill port. Subsequently, the electrolyte is injected through the fill port and into the nest. The vacuum may be applied via the fill port, or alternatively, a vacuum port may be provided in the cap through which the vacuum is applied.
Abstract:
A spill containment system and method that contain leaks and spills from devices including but not limited to batteries. The system neutralizes and absorbs leaks and spills to prevent the leaks and spills from spreading. The system not only detects leaks, but also indicates whether a leak has occurred. The system can communicate with personnel or devices to raise an alarm or cause corrective measures to occur. The spill containment system includes a battery rack inside a battery rack cabinet having a door. To open the door and gain access to the batteries, one of the rigid containment rails is removed such that the exposed flexible corrosion-resistant liner may be flexed to permit the opening and closing of the door.
Abstract:
A system for supplying fluid to a battery, a vehicle and a method for supplying fluid to a battery. The fluid supply system supplies fluid to a battery in a vehicle selectively powered by the battery, the vehicle including a frame supporting the battery, the battery including a battery cell, fluid being transmittable to the cell, gas generated during charging of the battery being transmittable out of the cell. The system is defined as including a tank for holding fluid, and a hydraulic circuit connecting the battery to the tank. The hydraulic circuit is defined as including an inlet conduit connectable between the tank and the cell, and an outlet conduit connectable between the cell and the tank, gas produced during charging causing fluid flow through the outlet conduit and to the tank. In the fluid supply system of the present invention, the gas produced during charging causes fluid flow through the system.
