    Abstract: A battery system may include an energy storage component the couples to an electrical system. The battery system may also include a first semiconductor switching device and a second semiconductor switching device. The first semiconductor switching device and the second semiconductor switching device each selectively couple the energy storage component to the electrical system. Additionally, the battery system may include 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. Further, the battery system may include a battery management system that controls operation of the first semiconductor switching device and the second semiconductor switching device to selectively couple the energy storage component to the electrical system. The battery management system may selectively couple the energy storage component to the electrical system based on an output current measurement of the energy storage component.

    Abstract: Relays having internal connections on both sides of their switches may be used in conjunction with a connector that integrates both the normal relay switch control lines with the sensing conductors of a control module for a battery module of an energy storage device. In this manner, sensing conductors may be routed along with the switch control lines for the relay instead of separately as described above. This integration reduces the complexity and cost associated with the energy storage device, because it reduces the number of separately routed lines and also eliminates the external connections for at least some of the sensing conductors.

    Abstract: An energy storage system may include battery packs, such that one terminal of the battery packs is electrically coupled to a resistor representative of an isolation resistance of the battery system. The system may include a semiconductor relay switch, a plurality of resistors configured to electrically couple to the battery packs via the semiconductor relay switch, a gain field-effect transistor (FET) configured to electrically short at least one resistor of the plurality of resistors, and a control system. The control system may send a first command to the semiconductor switch to close, acquire a first voltage waveform, send a second command to the semiconductor switch to open, send a third command to the gain FET to close, send a fourth command to the semiconductor switch to close, acquire a second voltage waveform, and determine the isolation resistance based on the first voltage waveform and the second voltage waveform.
