Abstract: A battery module includes module first and second terminals of opposing polarity. The module houses an array of electrochemical cells and includes a first bus bar that electrically connects the cell first terminals of at least a subset of the cells to the module first terminal, and a second bus bar that electrically connects the cell second terminals of the subset of the cells to the module second terminal. A first electrical connector electrically connects the first bus bar to a cell first terminal of each cell of the subset of the cells. The first electrical connector has a first current carrying capacity. A second electrical connector electrically connects the second bus bar to a cell second terminal of each cell of the subset of the cells. The second electrical connector has a second current carrying capacity. The first current carrying capacity is different than the second current carrying capacity.

Abstract: A switching device comprises a first and second connector, a first and second input, an output, a switch connected between the first connector and the second connector, a current sensor configured to measure a current flowing through the switch, and a controller connected to the current sensor, the switch, the first input, the second input, and the output. The controller is configured to: operate the switch based on a first control signal at the first input; connect the second control signal at the second input to the output; operate the switch to open in response to the current flowing through the switch exceeding a predetermined current limit; and disconnect the second control signal from the output in response to the current flowing through the switch exceeding the predetermined current limit.
