Battery system and hybrid current sensor therefor

Abstract

A hybrid current sensor (104, 204, 304, 404, 504, 554, 604, 624, 644, 664) may include a main conductor (206, 306, 406), having a first end (220) and a second end (222), wherein a current flow direction extends between the first end (220) and the second end (222), as well as a magnetic core (208, 308, 408), disposed at least partially around a middle portion of the main conductor (206, 306, 406). The magnetic core (208, 308, 408) may define a core gap region (226) above a first surface of the main conductor (206, 306, 406), where a chip assembly (218, 518, 618, 628) is disposed within the core gap region (226). As such, in a first portion the core gap region (226) has a first gap (G1) along a transverse direction, perpendicular to the current flow direction, and wherein in a second portion the core gap region (226) has a second gap (G2) along the transverse direction, greater than the first gap (G1).
