Abstract: A charge controller that responds to extreme transients in current, voltage, and temperature. The charge controller monitors the drift of the battery charging rate versus its request and compensates for wind up that may lead to uncontrolled current into a high-voltage battery. This bi-directional anti-wind up charge controller allows the battery management system to independently adjust the current request to the charger, which is primarily useful during vehicle component failure; charger side faults, over-commend, or uncontrolled current; and allows for safe and continuous charging during unexpected charger events. A dynamic saturation bound allows the charge controller to adjust its requested current and compensate for auxiliary current draws when the charger is capable of providing more current. The charge controller switches between voltage and current control based on the voltage of the battery, adjusting for variability in state-of-health, and temperature of the battery pack.
