  • Publication number: 20210270906
    Abstract: In a battery management controller, analog-to-digital conversion circuitry converts analog signals, indicative of a battery voltage, a battery current, and a battery temperature, to digital signals. A memory stores a remaining-capacity lookup table that includes multiple groups of data. Each group of data includes a voltage, a current, a temperature, and a parameter associated with a remaining capacity corresponding to the voltage, the current and the temperature. A processor searches the lookup table for a current parameter value and an end-of-discharge parameter value based on the digital signals, and determines a full available charge capacity of the battery based on the current parameter value and the end-of-discharge parameter value. The processor also counts the number of charges flowing through the battery based on a battery current. The processor further determines an available state of charge of the battery according to the full available charge capacity and the number of charges.

    Abstract: An ion implantation system is provided having an ion source configured to form an ion beam from aluminum iodide. A beamline assembly selectively transports the ion beam to an end station configured to accept the ion beam for implantation of aluminum ions into a workpiece. An arc chamber forms a plasma from the aluminum iodide, where arc current from a power supply is configured to dissociate aluminum ions from the aluminum iodide. One or more extraction electrodes extract the ion beam from the arc chamber. A hydrogen co-gas source further introduces a hydrogen co-gas to react residual aluminum iodide and iodide, where the reacted residual aluminum iodide and iodide is evacuated from the system.
