  • Patent number: 10763528
    Abstract: A method of operating a fuel cell stack that powers a vehicle includes determining when the vehicle is in a non-moving state, calculating an O2 concentration over time of an assumed enclosed space while the vehicle is in the non-moving state, establishing a set of O2 concentration concern levels that includes a first O2 concentration concern level being less than a standard atmospheric O2 concentration and a second O2 concentration concern level being less than the first O2 concentration concern level, comparing the O2 concentration of the assumed enclosed space over time with the set of O2 concentration concern levels, and operating the fuel cell stack without restriction when the vehicle is in the non-moving state so long as the O2 concentration of the assumed enclosed space remains greater than the first O2 concentration concern level.

  • Patent number: 10714735
    Abstract: A battery pack includes an enclosure containing a plurality of battery modules. A cooling system disposed among and electrically isolated from the plurality of battery modules uses a coolant solution that is a first mixture of a first liquid and a second liquid in a predetermined ratio to produce a first boiling point. Boiling of the coolant solution changes the predetermined ratio to produce a second boiling point that is higher than the first boiling point and that is sufficient to induce a thermal runaway condition for the plurality of battery module. A sensor monitors at least one operational characteristic of the plurality of battery modules and a controller determines a possible high voltage electrolysis within the enclosure based upon the at least one operational characteristic. A remediation system is responsive to the possible high voltage electrolysis to decrease risks associated with the possible high voltage electrolysis when operated.

  • Patent number: 10700376
    Abstract: Methods for fast-charging batteries while minimizing lithium plating (LP) comprise charging the battery in a first phase at a near-maximum charging current, subsequently charging the battery in a second phase by decreasing the charging current while charging in order to maintain the anode potential equal to or above an anode potential threshold, and subsequently charging the battery in a third phase at constant cell potential such that the cathode potential remains below a cathode potential threshold. LP can be detected by determining the derivative of the charging current and examining the derivative for smooth curves or local discontinuities, wherein a smooth curve indicates the absence of LP and a curve with a local discontinuity indicates the presence of LP. A fast-charging profile can be defined by plotting the cell potential vs. the charging current from the first phase, the second phase, and the third phase to define a fast-charging profile.
