Power is provided from a power source and a status of the power source is signaled by controlling a waveform of an AC voltage generated from the power source. The status may include, for example, a capacity of the power source. In some embodiments, a frequency of the AC voltage may be controlled to signal the status. The power source may include, for example, an uninterruptible power supply (UPS), and signaling a status of the power source may include controlling an inverter of the UPS to signal the status. Related systems are also described.

Disclosed is an exemplary method for optimizing vehicle performance. The method includes determining an optimized drive torque for maximizing vehicle fuel economy and detecting a driver requested drive torque. A determination is made on whether the driver requested drive torque is performance related or safety related. The arbitrated drive torque is set to the optimized drive torque when it is determined that the driver requested drive torque is not performance and safety related. The arbitrated drive torque is set to the driver requested drive torque when it is determined that the driver requested drive torque is either performance or safety related.
