  • BATTERY CASE FOR RECEIVING ELECTROCHEMICAL ENERGY-STORAGE DEVICES
    Publication number: 20120321919
    Abstract: A battery case includes a deformable lateral wall. The battery case is provided to receive at least one electrochemical energy storage device. An electrochemical energy storage device includes a cell frame, which partially surrounds the device and in some areas forms the outer wall of the battery case. The battery case also includes a case cover, by which at least one electrochemical energy storage device can be electrically contacted. A lateral wall forms at least in some areas the outer wall of said battery case, wherein the stiffness of said lateral wall is less than the stiffness of the cell frame. When there is a pressure difference between the inner space of the battery case and the environment around the battery case, the lateral wall is therefore deformed and the volume of the battery case increases. The lateral wall is connected at least in some areas to said cell frame in a gas-tight manner.

  • Battery device
    Patent number: 6579642
    Abstract: A battery device designed so that a plurality of battery modules (1) are arranged in rows at given spaces in a enclosure (2). Turbulence accelerators (5), such as dummy battery units or the like, are provided in a position on the uppermost-stream side of the enclosure in which air flows in the direction of arrangement of the battery modules. The heat transfer ability for the battery modules in the upper-stream position is enhanced by the turbulence accelerators which disorders the airflow introduced into the enclosure. Auxiliary coolant intake ports (7) for the introduction of a coolant are provided in the middle of an airflow path, whereby the heat transfer ability on the lower-stream side is enhanced, so that battery temperature differences between the battery units arranged in the enclosure can be restrained. Thus, a simple-construction battery device is realized enjoying improved quality and operation stability.

  • Method of dumping and collecting corrosive substances from _automotive batteries
    Patent number: 4203699
    Abstract: A novel battery dumping apparatus is described which is uniquely suited for dumping corrosive substances, such as battery acid, simultaneously from a number of automotive batteries. The novel apparatus generally comprises a sealed tube adapted for rotation through an arc of less than 360 degrees. Within the tube are disposed two parallel spaced apart baffles which together form a sealed battery processing channel. This battery processing channel is pierced by a plurality of rods disposed in a plane which bisects the aforementioned baffles. These rods are ultimately caused to rotate in opposite directions by a gear drive disposed outside of said battery processing channel but within said tubular member. These gears are, in turn, caused to drive said rods by a pneumatic motor which is mounted outside of said tubular member.
