Abstract: A current sensing device may include an integrated trace type current sensor assembly. The current sensor assembly may include a chip body, an integrated electrical conductor, and a current sensor. The current sensor measures an amount of first current that flows through the integrated electrical conductor. The current sensing device may also include an external resistive element connected in parallel to the integrated electrical conductor. A second current may flow through the external resistive element. The amount of the first current measured by the current sensor is indicative of a total current that is a sum of the first current and the second current. The total current may be determined based on the amount of the first current measured by the current sensor, based on a first resistance value of the integrated electrical conductor, and based on a second resistance value of the external resistive element.

Abstract: A battery is electrically coupled to a bidirectional power converter (i) to output discharge current through a first electrical path between battery cells and the bidirectional power converter, and (ii) to receive charging current through the first electrical path from the bidirectional power converter. A battery management system is configured to monitor the battery cells, detect a fault condition of the battery cells, transmit a first control signal to the bidirectional power converter to control the bidirectional power converter to cease operating in response to detecting the fault condition of the one or more battery cells, and transmit a second control signal to a switching element to close the switching element to cause a short circuit between a positive side and a negative side of the battery to cause a first overcurrent protection device to open to prevent current from flowing into or out of the battery cells.
