A system for determining the servicing needs of a vehicle. In various embodiments, the system includes a remote server and a vehicle control module of the vehicle. The vehicle control module includes a first communication interface to enable communications with at least one vehicle device via a network fabric of the vehicle. The vehicle control module is configured to receive status data, from the vehicle device, relating to a performance status or operational status of the vehicle. The vehicle control module further includes a second communication interface that enables wireless communications with the remote server. The wireless communications include sending status data to the remote server. The remote server is configured to receive and interpret the status data to determine if the vehicle requires service, and send a response to the vehicle. When service is required, the response may cause the vehicle to provide a service indication.

The invention features redox flow batteries and compound useful therein as negolytes or posolytes. The batteries and compounds are advantageous in terms of being useable in water solutions at neutral pH and have extremely high capacity retention. Suitable negolytes are diquaternized bipyridines, suitable posolytes are water-soluble ferrocene derivatives.

Current imbalances between parallel switching devices in a power converter half leg are reduced. A gate driver generates a nominal PWM gate drive signal for a respective half leg. A first feedback loop couples the nominal PWM gate drive signal to a gate terminal of a respective first switching device. The first feedback loop has a first mutual inductance with a current path of a first parallel switching device and has a second mutual inductance with a current path of a second parallel switching device. The first and second mutual inductances are arranged to generate opposing voltages in the first feedback loop, so that when all the parallel switching devices carry equal current then the voltages cancel.

A system and method for performing vehicle safety processing within a vehicle includes determining whether a driver is present in a vehicle, receiving driver sensed data, processing the driver sensed data to recognize a safety issue. The method continues by determining if the driver sensed data also indicates an externally sensed safety issue. For the driver sensed data without the externally sensed safety issue, the method includes generating one or more control signals to activate a driver awareness measure. For the driver sensed data with an externally sensed safety issue, the method includes activating auto safety precaution measures, determining whether the auto safety measures were successful in avoiding an accident, and, if not, recording the driver sensed data in a one-time programmable (OTP) memory device.
