An apparatus for a vehicle 100 driven by an electric motor 123, powered by an energy storage means 150 such as a battery, generates an audible sound dependent on whether the electric vehicle, which may be a hybrid electric vehicle (HEV) 100 is charging. The sound or sonic signature is generated upon detecting the proximity of a portable user identification device 190, such as an electronic key or wireless key. Whether charging is occurring may depend on a charging current, or a current and target state of charge (SOC). The audible alert may also depend on a determination that a user or driver wishes to unlock the vehicle. The apparatus may provide different sounds or noises depending on charge state. The charging may be inductive or non-contact.
