Battery systems and methods for bi-directional current control

An energy storage system, comprising:

• an energy storage component;
• an electrical system of a vehicle;
• a first semiconductor switching device and a second semiconductor switching device each configured to selectively couple the energy storage component to the electrical system;
• a first diode coupled in parallel with the first semiconductor switching device and a second diode coupled in parallel with the second semiconductor switching device;
• a battery management system comprising a processor and one or more tangible, non-transitory machine-readable media comprising processor-executable instructions to, upon receiving an indication to couple the energy storage component to the electrical system:
• provide a first signal to a first gate line of the first semiconductor switching device to activate the first semiconductor switching device;
• receive a measured current of the energy storage component;
• provide a second singal to a second gate line of the second semiconductor switching device to activate the second semiconductor switching device when the measured current is greater than a predetermined threshold current;
• and
• provide a third signal to the second gate line of the second semiconductor switching device to deactivate the second semiconductor switching device when the measured current is less than the predetermined threshold current.

A tangible, non-transitory computer readable medium of a battery management system configured to store instructions executable by a processor, wherein the instructions comprise instructions to cause the processor to:

• provide a first signal to a first gate line of a first semiconductor switching device to activate the first semiconductor switching device, wherein activating the first semiconductor switching device enables a current to flow from an energy storage component across the first semicondcutor switching device, through a diode coupled in series with the first semiconductor switching device, and to an electrical system;
• receive a measured current of the energy storage component;
• provide a second singal to a second gate line of a second semiconductor switching device to activate the second semiconductor switching device when the measured current is greater than a predetermined threshold current, wherein activating the second semiconductor switching device enables the current to flow from the first semiconductor switching device, across the second semiconductor switching device, and to the electrical system;
• and
• provide a third signal to the second gate line of the second semiconductor switching device to deactivate the second semiconductor switching device when the measured current is less than the predetermined threshold current, wherein deactivating the second semiconductor switching device enables the current to flow across the first semiconductor switching device, through the diode coupled in series with the first switching device, and to the electrical system.
