A current sensor arrangement includes a first conductor configured to conduct a first portion of a primary current in a current flow direction; a second conductor configured to conduct a second portion of the primary current in the current flow direction; and a magnetic sensor. The first and second conductor are coupled in parallel. The first current produces a first magnetic field as it flows through the first conductor and the second current produces a second magnetic field as it flows through the second conductor. The first conductor and the second conductor are separated from each other in a first direction that is orthogonal to the current flow direction, thereby defining a gap. The magnetic sensor is arranged in the gap such that the first conductor is arranged over a first portion of the magnetic sensor and the second conductor is arranged under a second portion of the magnetic sensor.

Current sensor for improved functional safety

Techniques for monitoring an internal pressure of a battery cell, whereby a membrane that is part of an outer shell of the battery cell is used as an element of capacitive-based or inductive-based sensor circuitry in order to measure a change of capacitance or inductance under deformation of the membrane from the internal pressure of the battery cell. The change of capacitance or inductance may in turn be used to derive a value for the internal pressure of the battery cell.
