Methods and apparatus are provided for a vehicle electronic power system. In one exemplary embodiment an energy harvesting device is configured to generate electricity in response to vibration of the vehicle occurring during normal vehicle operation. The energy harvesting device may be tuned to a frequency that falls within a peak energy region in a vibration profile of the vehicle. The power system may further include a charging circuit connecting the energy harvesting device to a rechargeable battery provides electrical power to an electro-mechanical vehicle component or system.
