摘要： A method for constant pressure regulation of battery cells includes disposing the cells in a stacked arrangement within a battery cell placement volume of an apparatus configured to maintain a constant pressure on the cells, providing a gas pressure within a chamber of the apparatus, thereby causing an initial pressure to be applied on the battery cells, and detecting an expansion of the battery cells during a predetermined timespan using a linear displacement sensor. During the predetermined timespan, if the detected expansion is less than a maximum allowable expansion minus a predetermined measurement error, then the gas pressure within the chamber is increased, and if the detected expansion is greater than the maximum allowable expansion plus the predetermined measurement error, then the gas pressure within the chamber is decreased. An apparatus for constant pressure regulation of battery cells is also provided.

摘要： A method of leak testing a fluid passage of a part manufactured from a low conductivity material includes measuring an electrical resistance between an interior wall surface of the fluid passage of the part, and an exterior wall surface of the fluid passage of the part. The measured electrical resistance is compared to a threshold value to determine if the measured electrical resistance is equal to or greater than the threshold value, or if the measured electrical resistance is less than the threshold value. The threshold value is equal to a nominal wall thickness of the fluid passage multiplied by a resistivity of the material used to form the part. The part passes the leak test when the measured electrical resistance is equal to or greater than the threshold value. The part fails the leak test when the measured electrical resistance is less than the threshold value.

摘要： A battery pack with a drain plug and a circuit to detect when a liquid coolant has entered the battery pack. A soluble plug may be disposed within the cavity of the carrier; the soluble plug is configured to at least partially dissolve when fluidly coupled with a coolant allowing a portion of the coolant to flow between the inlet and the outlet and out of the battery pack. A strain gauge cooperative with the carrier such that a measured resistance change in the strain gauge corresponds to the soluble plug in contact with the liquid coolant. An associated circuit with the drain plug provides notification of the activation of the drain plug to the on-board computer systems.
