A fuel-empty-state recovery determination method including: when driving of the hybrid vehicle is started, performing rotation speed control of an electric power generator for a specified time, and then stopping the rotation speed control; in a case where it is detected that a state in which the rotation speed of an engine after stopping the rotation speed control is higher than a threshold continues for more than a first determination time, determining that recovery has been made from a fuel-empty state; in a case where the measured time does not exceed the first determination time, starting measurement of the time during which the rotation speed of the engine is lower than the threshold; and in a case where the measured time exceeds a second determination time, maintaining determination that the vehicle is in a fuel-empty state.

An apparatus structured to control an electric vehicle accessory of an electric vehicle during a charge event includes a controller communicatively coupled to a battery and an electric vehicle accessory. The controller is structured to determine that the battery of an electric vehicle is undergoing a charge event, and based on determining that the battery of the electric vehicle is undergoing the charge event, place the electric vehicle accessory in an on-state during the charge event, and cause the electric vehicle accessory to recharge by absorbing energy from the charging station during the charge event.

A vehicle may include an auxiliary battery to prevent full discharge of a main power source while remotely controlling electronic devices of the vehicle, wherein the vehicle may include a communication device configured to receive a control signal indicating a control command from a mobile device; a controller configured to control a target of control based on the control signal; and a power management device including an auxiliary battery and configured to supply power to the controller using the auxiliary battery when the communication device receives the control signal while an ignition of the vehicle is turned off.

A charging system with a sensor diagnosis function is provided. The system includes an AC input voltage sensor that detects a voltage of an input end with an AC power applied thereto and a resistor that is connected to the input end. A power factor correction circuit unit adjusts and outputs a power factor of AC power applied through the resistor. An output voltage of the power factor correction circuit unit is applied to a capacity of the system. A controller then diagnoses the AC input voltage sensor based on a value of current passing through the resistor, a value of a voltage of the capacitor, and a resistance value of the resistor.
