Abstract: A method for determining state of charge (SOC) of a battery system based upon an equivalent circuit of the battery system. A potential and resistance of the equivalent circuit are computed. The method uses a least squares regression means, and includes: providing a plurality of data points as a starting point based upon determinations including measurement or prior computation, wherein the determinations include a determination of a voltage of the battery system; weighting the plurality of data points; and computing values of the resistance and potential based upon weighted data points using recursive formulas, wherein only a state at a previous time is reflected respectively.

Abstract: A conveyor for a centrifuge and a centrifuge with such a conveyor, the conveyor having a plurality of spaced-apart flight members spaced apart along its length, a plurality of support members extending between, and connected to the flight members, the support members spaced-apart around the flight members, the members and support members defining a plurality of open areas through which fluid to be treated by the centrifuge is flowable from within the conveyor out into the bowl. In one aspect, a fluid velocity decreasing chamber is provided between an exit tube end and impeller apparatus for radially accelerating the fluid with the conveyor. In certain aspects the open “caged” conveyor structures diffuses fluid flow from the conveyor so that a dispersed unfocused flow of fluid exits the conveyor into the bowl, and, in one particular aspect with feed from within the conveyor to space adjacent a beach area of the bowl.

Abstract: In one aspect of the invention as applied to vehicles, such as electric automotive systems, battery equalization is optimized through performance simultaneously with other routine vehicle functions in the way of maintenance during periods when the temperature of the battery pack is in a lower temperature regime. An equalization current is chosen as a function of the ambient conditions and effectiveness of the thermal system detected by the battery pack control module, so that heat can be minimized as well as then more easily removed from the battery pack, thereby also reducing the length of the process. Opportunity equalization therefore is performed more frequently than is typical at more convenient times and in a manner to optimize the process in view of existing conditions.
