A bidirectional power converter that includes phase legs that are used for both powering a multiphase load from a battery and for charging the battery from a power source. The converter includes fault detection for detecting faults in the phase legs of the converter. In response to a detection of a fault, the converter can utilize a spare phase leg in charging the battery such as in a multiphase charging mode or in single phase charging mode.

A multi-cell battery apparatus is provided, according to certain aspects, including a battery with a plurality of voltage-stacked battery cell circuits, a switchable resistive-divider circuit and a control circuit. The control circuit selectively activates the switchable resistive-divider circuits and, in response to the respective switchable resistive-divider circuits being selectively activated, the control circuit measures the controlled-load voltage drops. These aspects are used to allow open load detection without interfering with the cell balancing mechanism and the accuracy of the redundant measurements performed on these pins in a battery management system.

The invention relates to a computer architecture and functional architecture for the operation of electric power steering, to an electronic control unit, and to power steering, having a first group of modules with a high probability of failure and a second group of modules with a low probability of failure. In this case, the modules of the first group have a higher probability of failure than the modules of the second group. The first group of modules is maintained redundantly in this case and, as a result, divided into main modules and into the redundant implementation of what are known as secondary modules. The main modules are arranged on a main control path and the secondary modules are respectively arranged on a secondary control path. Each of these control paths ultimately produces a control signal, i.e., a main control signal and a secondary control signal. A multiplexer is used to decide which of these two control signals is forwarded to modules from the second group. This second group of modules is implemented only once and not present in redundant form.
