Abstract: A method and apparatus for charging a rechargeable battery in which a constant current (Icc) is first applied until the rated voltage of the battery is reached, followed by a period (Rc) during which a reduced current (Ir) is applied to the battery. The reduced current results in lowering the amount of unwanted heat being dissipated in the charge-current transistor connected to the battery. Finally, a constant voltage (Vcv) is applied to the battery to finish the charging cycle. Reducing the heat dissipation enables the use of smaller less expensive charge-current switch transistors, which for example, are advantageous in applications such as mobile communication devices or other portable electronics assemblies.

Abstract: A portable multi-band communication device has a power amplifier (216), a battery (270) for supplying power to the power amplifier, and a controller (240), which controls an output power level of the communication device by generating a digital control signal (DAC value) for the power amplifier. The controller also monitors the digital control signal (DAC value) and in response determines a consumption of electric energy from the battery (270).

Abstract: Method and apparatus for calibrating a rechargeable battery (28) for mobile telephones (10) and other electronic devices. Calibration is accomplished during a process of completely charging (105) the battery (28) by determining (120) the total amount of charge accepted by the battery (28) during the charging process, and providing (130) a value of total charge capacity of the battery (28) based, at least in part, on the total amount of charge accepted by the battery (28). The total charge capacity of the battery (28) is used to calculate remaining battery (28) capacity and to predict the remaining operational time of the device. Alternative calibration procedures are provided (125, 160) if the battery (28) is not completely discharged before charging or if the battery (28) is not fully charged by the charging process. The calibration procedures of the invention require no interaction from a user (other than his initiating the normal charging process), and typically permits a calibration to be carried out notwithstanding varying usage habits of different users.

Abstract: Digital, serial communication over an interface between an electronic device (102) and a battery (103) attached thereto comprises transmission of bytes (300) consisting of a number of bits. Each bit is defined by one of a high level and a low level, and a leading bit (304) of each byte is of a first one of said high and low levels. The method comprises the step of transmitting the other of the high and low levels for a first period of time (403, 405) immediately prior to said leading bit (304). When the leading bit of a byte is always of the same level (i.e. either high or low) and a period of the opposite level precedes the leading bit, it is very easy and simple to ensure that the sending as well as the receiving party is ready for the communication to take place and adjusted to the actual direction of communication.
