Abstract: In a method of charging a battery pack, the pack is inserted in a charger and an initial set of checks of cell voltage and pack temperature is performed. Once the initial set of checks is satisfied, the cells may be charged at a first constant current level. The first constant current level is adjusted to one or more lower levels of constant current until cell voltages of all the cells are within a full charge voltage window. The voltage window is defined between a minimum full charge cell voltage level and a maximum full charge cell voltage level. The charge may be terminated once all of the cells are within the full charge voltage window.

Abstract: A battery detect circuit (32) is provided that is operable to dispose a sense resistor (50) in series with the battery to determine whether the charge is being provided to the battery or being extracted from the battery. The voltage across the sensor resistor (50) is sensed by a voltage/frequency converter (52). The voltage/frequency converter (52) is a differential structure comprised of two integrator structures (102) and (104) that are operable to utilize a switched capacitor configuration to drive comparators on the output thereof. Each of the integrator structures (102) and (104) has associated therewith passive elements and active elements. The integrators (102) and (104) have associated therewith integration capacitors (147) and (149). Additionally, there are two operational amplifiers (143) and (145) that provide the active components of each of the integrators (102) and (104). The various switched capacitor circuits (161) and (163) associated with the amplifiers (143) and (145) are provided to provide the integration operation. Both the amplifiers (143) and (145) and their associated switched capacitor circuits (161) and (163) are dynamically balanced such that they are switched between integrator (102) and integrator (104) on a periodic basis. This therefore allows the errors between the active and passive elements to be switched between the two integrators (102) and (104) such that no accumulative error occurs.

Abstract: A method of generating data for use in monitoring and controlling the charge status and discharge status of a secondary battery, which is carried out by a microcomputer installed in a secondary battery pack. The data generating method includes calculating a discharge capacity iteratively. The calculated discharge capacity is added to a required full charge capacity determined in a previous period of time, and the sum is determined as a required full charge capacity for each iteration. Also, if an average voltage value for each iteration for the secondary battery is less than a lower limit of the full discharge voltage value, a reference full charge capacity is updated with the required full charge capacity for each iteration.
