Abstract
A recharging system includes a contact pad charger having a compressible contact pad conformable to a rechargeable device body for charging a power storage device in the rechargeable device body. The contact pad charger includes a power supply configured to provide a supply voltage. The compressible contact pad is electrically coupled to the power supply and defines a first variable resistance in response to a first conductor compression. The rechargeable device body includes a power manager electrically coupled to the power supply and is configured to receive a variable input voltage in response to a first variable voltage drop across the first conductor and to provide a regulated output voltage in response to the received variable input voltage. The regulated output voltage is less than the supply voltage. The power storage device is electrically coupled to the power manager and configured to receive the regulated output voltage for charging.
