摘要： A battery module having a cooling plate assembly made from two non-contiguous cooling plates is provided. Each cooling plate has a side panel contiguous with a base panel, and the cooling plates are disposed opposite one another such that the base panels are coplanar and separated by a gap. An inlet duct runs along an upper edge of each side panel, and a manifold having coolant channels in fluid communication with the inlet duct is located in each side panel. The base panels have an outlet duct in fluid communication with the manifold. The cooling plate is designed to decrease friction loss as coolant flows through the inlet duct, manifold and outlet cut, and coolant channels in the manifold are designed to maintain a uniform flow rate across the manifold. Individual cells are disposed in the assembly such that the cell sides and bottoms are in heat-transfer contact with the plate side and base panels, respectively. The design of the battery module reduces operational temperature variation in the cells across the battery module and within each battery cell. Methods for reducing coolant flow friction loss, for establishing a more uniform coolant flow rate, and for reducing temperature variation are also provided.
摘要翻译：提供具有由两个不连续冷却板制成的冷却板组件的电池模块。每个冷却板具有与基板相邻的侧板，并且冷却板彼此相对设置，使得基板是共面的并且由间隙分开。入口管道沿着每个侧板的上边缘延伸，并且具有与入口管道流体连通的冷却剂通道的歧管位于每个侧板中。底板具有与歧管流体连通的出口管道。冷却板被设计成当冷却剂流过入口管道，歧管和出口切口时减小摩擦损失，并且歧管中的冷却剂通道被设计成在歧管上保持均匀的流速。单独的电池被放置在组件中，使得电池侧和底部分别与板侧和底板热传递接触。电池模块的设计降低了电池模块和每个电池单元内的电池的工作温度变化。还提供了减少冷却剂流动摩擦损失的方法，用于建立更均匀的冷却剂流动速率和降低温度变化的方法。

摘要： A battery pack and method of cooling a battery pack. In one form, the battery pack is an assembly made up of numerous battery cells arranged within numerous modules. Cooling channels that receive cooling fluid from a ducted supply are placed between adjacent cells or cooling plates within each of the modules. The ducted supply includes beads or related area-increasing undulations that are designed to improve both the stiffness of the ducting as well as the uniformity of the flow rates of individual cooling channels within each of the modules. In one form, the pressure-enhancing beads are placed in an inlet portion of the ducting that is adjacent a forward portion of one or more of the sequentially-encountered modules in order to promote a more equitable distribution of the cooling fluid between the various cooling channels within each of the modules.

摘要： A self-cleaning lens system disposed adjacent a camera is disposed. The system may incorporate a piezoelectric (PZT) lens system having a first PZT element secured to a first peripheral portion of the lens element, which may be responsive to an alternating current (AC) signal applied to the first PZT element. An AC signal may excite the first PZT element to cause shear displacements in opposite longitudinal directions and to create an oscillating shear motion for the first PZT element. The oscillating shear motion may cause an oscillating rotational movement of the lens element that removes the environmental element from a surface of the lens element.
