  • Apparatus and method for controlling battery charging with variable current
    Patent number: 6255802
    Abstract: An apparatus provides a charging battery for variable currents. The apparatus comprises a first current sensor which transforms a current into a first signal; a controller which depends on the first signal to transform a power into a current in order to supply the variable currents to charge; a second current sensor which transforms the variable currents into second signals and passes the variable currents to charge up the charging battery; a detector which relies on the second signal and a third signal in response to the charging battery to trigger the controller to decide whether to disable from the controller or not.
