    Abstract: The present disclosure includes a battery module having a housing that includes a lid and a battery cell with a battery cell terminal and a battery cell vent on an end of the battery cell. The battery cell vent is configured to exhaust battery cell effluent. The battery module includes a printed circuit board positioned in an immediate vent direction of the battery cell, a vent shield channel positioned between the battery cell vent and the printed circuit board along the immediate vent direction of battery cell effluent, where the vent shield plate is immediately adjacent to the printed circuit board and configured to block the effluent from contacting the printed circuit board and to redirect the battery cell effluent along a desired vent path, and a module vent fluidly coupled to the desired vent path and configured to direct the battery cell effluent out of the battery module.

    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.
