The embodiments describe a system and the corresponding assembly techniques of a battery submodule top cover. The battery submodule top cover has at least one electrical hybrid interconnect coupled to a substrate. The hybrid interconnect comprises at least a first portion made of a first metal type, and a second portion made of a second metal type. The first portion and the second portion of the hybrid interconnect are joined together such that an electrical connection may be made between two battery cell tabs where each battery cell tab is made of a different type of metal.

A system and method are disclosed for an electrical earthing or grounding system to protect electrical systems and structures. Such systems and structures are efficient at dissipating broadband energy. An earthing mix system in contact with a grounding electrode is separated into functional components; a conductive earthing mix which is in contact with an electrical conductor and an impedance transitioning earthing composition which is in contact with the conductivity earthing mix. The conductive earthing mix absorbs, radiates, conducts, and dissipates electrical energy. The impedance transitioning earthing mix acts as a lossy impedance matching media to reduce reflections and improve energy transfer. A conductive slurry mix fills in voids and aids in contact between the other elements. A grounding electrode system connects an electrically conductive electrode with an earthing mix system to achieve reduced impedance mismatch between the local soil and the grounding system itself while expanding the bandwidth of the overall system's grounding capability beyond traditional solutions.
