Systems and methods for controlling battery current
A battery system comprising multiple battery packs. A battery pack of the battery packs includes a battery, voltage sense circuitry, a control circuit, a control switch and current regulation circuitry. The voltage sense circuitry senses a battery voltage of the battery and an input voltage of the battery pack. The control circuit is coupled to the sense circuitry and is operable for adjusting a level of a reference signal based on attribute data associated with the battery pack and a difference between the battery voltage and the input voltage. The control switch is operable for passing a battery current flowing through the battery. The current regulation circuitry is coupled to the control circuit and the control switch, and is operable for controlling the control switch to regulate the battery current according to the reference signal.
