    摘要： A voltage/current regulator regulates charging of a rechargeable battery in a portable apparatus that includes a transistor and a controller means coupled to the transistor for controlling the charging current to the battery. The controller determines the power dissipation in the transistor of the regulator. If the power dissipation is above a maximum allowed power dissipation, the controller decreases the charging current by a particular current step. Otherwise, the controller determines if the power dissipation will exceed the maximum allowed power dissipation if the charging current is increased by the current step. If not, the controller increases the charging current by the current step.

    摘要： 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.

    摘要： Method and apparatus for calibrating a rechargeable battery for mobile telephones and other electronic devices. Calibration is accomplished during a process of completely charging the battery by determining the total amount of charge accepted by the battery during the charging process, and providing a value of total charge capacity of the battery based, at least in part, on the total amount of charge accepted by the battery. The total charge capacity of the battery is used to calculate remaining battery capacity and to predict the remaining operational time of the device. Alternative calibration procedures are provided if the battery is not completely discharged before charging or if the battery 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.

    摘要： A method and apparatus for charging a rechargeable battery in which a constant current is first applied until the rated voltage of the battery is reached, followed by a period during which a reduced current 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 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.
