Abstract:
1. A rechargeable battery assembly, the battery assembly having a prismatic form for being received within a mobile device and comprising: positive and negative terminals to supply a voltage to said mobile device; a built in data and power connector; circuitry to provide charge control; and, one or more rechargeable battery units arranged to provide a source voltage; wherein said battery assembly is mechanically reversible between a deployed configuration having a general form and functions of a conventional battery format in which said data and power connector, said circuitry and said rechargeable battery units are contained within the overall volume of the prismatic battery form and a charge configuration in which the data and power connector is moved relative to the other parts of the battery assembly so to be made accessible; wherein said battery assembly in the deployed configuration is capable of providing a DC discharge to at least one voltage level via said positive and negative terminals and can be charged by means of a suitable external charger device via said positive and negative terminals; and, wherein said battery assembly in the charge configuration can be charged by means of the integral charge control circuitry when the data and power connector is connected to a suitable powered receptacle on a computing or peripheral device; wherein the battery assembly has power conversion circuitry including a microcontroller, the circuitry being arranged to achieve DC voltage conversion under the control of the microcontroller during at least one of: i) the charge mode of the battery assembly, such that the external DC charge voltage supplied to the connector is different from the DC voltage supplied to the one or more rechargeable battery units during charging; and, ii) the discharge mode of the battery assembly, such that the DC discharge voltage is different from the DC source voltage of the one or more rechargeable battery units during discharge.
