Abstract: An electrical system is described herein, where the electrical system may be implemented as a low voltage electrical system for a tandem rear axle of an electric vehicle. In an embodiment, the electrical system may include a battery pack including a plurality of battery blocks, each battery block of the plurality of battery blocks including one or more batteries, where the one or more batteries of each of the plurality of battery blocks are arranged in series, and where the battery blocks of the plurality of battery blocks of the battery pack are arranged in parallel. The electrical system may also include a motor coupled via electric components with the battery pack to receive power from the battery pack within a target voltage range and the axle may be coupled with the motor, where the axle is driven by the motor.

Abstract: A seal assembly capable of sealing a rotatable shaft protruding from a fluid-containing chamber in an internal combustion engines and the like. The seal characteristics of the seal assembly are largely attributed to surface interface between the seal cap and the main body of the seal assembly. More particularly, the seal cap includes a pair of legs each having fractured ends which are in end-to-end engagement with corresponding legs of the main body also having fractured ends. By mating corresponding fractured ends of respective legs of the seal cap and the main body, an improved seal is provided. A method by which such an improved seal assembly can be manufactured is also disclosed.
