Abstract
A vehicle includes a wakeup circuit and a connector. When the connector is connected to a charging station, the wakeup circuit receives a charging control signal from the charging station. The wakeup circuit generates a wakeup pulse using a filtered version of the charging control signal (CPFS) and a reset signal. The reset signal transitions state when the filtered version of the charging control signal crosses a threshold. In one embodiment, the wakeup circuit comprises a reset circuit, a wakeup pulse generator, and an opto-coupler. The reset circuit generates the reset signal that inhibits the wakeup circuit so that only one wakeup pulse is generated until removal of the CPFS. In another embodiment, the wakeup circuit includes a filter that generates the CPFS, a wakeup comparator circuit that generates the reset signal based on the CPFS, and a reset circuit that generates the wakeup pulse based on the reset signal.
