A torque sensor unit may include a ring magnet that is connectable to a first partial shaft and is concentric with a longitudinal axis. Two first magnetic flux conductors are connectable to a second partial shaft, are arranged in a ring magnet magnetic field, and conduct magnetic fluxes. A spatially fixed sensor unit may have two second magnetic flux conductors and a magnetic sensor on a printed circuit board, all of which are receivable in a housing. The sensor unit can detect a change in a rotation angle between the partial shafts by measuring magnetic flux density between the first magnetic flux conductors. A second housing surrounds the ring magnet, the first magnetic flux conductors, and the sensor unit. A magnetic shield surrounds the sensor unit at least partially circumferentially relative to the longitudinal axis and is arranged between a housing cover closing the second housing and the second housing.

A state of charge of a battery is estimated by a battery model specific to the battery. The battery model provides a section-wise defined correlation of terminal voltage values depending on state of charge values. Each of sections of the battery model delimits a monotonic dependence of the correlation from others of the sections. By segmenting the correlation of terminal voltage values depending on a state of charge value into sections, each segment within such the section-wise defined correlation of terminal voltage values depending on state of charge values is mathematically spoken a bi-unique function suitable for transformation into an inverse function defined within the section. The estimated state of charge may be continuously refined by an iterative feedback loop including coulomb counting for estimating a battery charge value, where refined estimated battery charge values state of charge values at a previous cycle are projected forward to the current cycle.
