摘要： A system and method for controlling the voltage on a high voltage bus in a fuel cell system in response to a failed high voltage battery. The method includes determining if the high voltage battery has failed, and disconnecting the battery from the high voltage bus in response to a failure. The method measures the voltage of the fuel cell stack by a DC boost circuit and converts the measured voltage to a voltage set-point value that sets the voltage on the high voltage bus, where the voltage set-point value changes as the measured voltage changes. A supervisory controller sets the media flow to the fuel cell stack and determines a minimum stack voltage limit value based on the stack maximum current draw that is used to determine a high voltage bus lower limit value.

摘要： Systems and methods are provided for regulating the state of charge of a battery. An exemplary electrical system includes a fuel cell coupled to a bus and a battery coupled to the bus via a switching arrangement coupled to a capacitor. An exemplary method for operating the electrical system involves operating the switching arrangement such that a voltage of the battery is substantially equal to a voltage of the fuel cell when a state of charge of the battery is greater than a lower threshold value and less than an upper threshold value, and operating the switching arrangement to couple the capacitor electrically in series between the battery and the bus when the state of charge of the battery is not between the lower threshold value and the upper threshold value.

摘要： A method for gathering information from battery sensors—for instance, information regarding the state-of-charge (SOC), temperature and/or other characteristics of battery cells in a vehicle battery pack—and using that information to estimate or predict battery degradation or state-of-health (SOH). According to an exemplary embodiment, the method uses both a time-based algorithm and an event-based algorithm to predict or estimate battery degradation. The event-based algorithm may select certain data from the battery conditions (e.g., a state-of-charge (SOC) swing (ΔSOC) or an SOC maximum (SOCMax)), instead of using the entire set of battery condition data, and may use this information in its prediction or estimate.

摘要： A system for reducing oscillations on a high voltage bus. The system includes a high voltage battery electrically coupled to the high voltage bus and a DC/DC boost converter electrically coupled to the high voltage bus and a fuel cell stack. The DC/DC converter includes a current controller that selectively controls the current provided by the fuel cell stack. A system controller provides a stack current set-point to the DC/DC converter. The DC/DC converter includes a voltage device that receives a voltage signal from the bus and provides a time derivative of the voltage signal that defines voltage changes on the bus over time. The time derivative signal is provided to a summer that adjusts the current stack set-point to provide a modified current set-point to the current controller that selectively adjusts the current provided by the fuel cell stack to dampen oscillations on the high voltage bus.

The modular assembly includes a plurality of U-shaped members having cooling fluid channels, where the U-shaped members are mounted together in a stacked manner. Each cooling fluid channel includes an inlet and outlet orifice, where the orifices in the stacked U-shaped members align with each other. The modular assembly also includes a plurality of thermally conductive carrier plates, where a battery cell is mounted to and between opposing carrier plates. Side edges of the carrier plates are mounted in opposing retention slots in opposing U-shaped members where a cooling fluid channel in the U-shaped member is provided within the retention slot so that a cooling fluid flowing through the cooling fluid channel and the U-shaped members contacts the carrier plates and draws heat therefrom.

摘要： A fuel cell system includes a fuel cell having conductive coolant flowing there through and a high voltage direct current (HVDC) bus interconnected with the fuel cell. An active isolation circuit includes coolant fault current sensors that detect a fault current (also called residual current) in the coolant and generates a fault signal when the fault current is detected. A switching circuit compensates and redirects the fault current based on the fault signal, providing active fault current limitation thereby.

摘要： A fuel cell assembly having a terminal plate that is isolated from fluid flows passing to the fuel cell stack through manifolds is provided. A corrosion resistant member is positioned between the fuel cell stack and the terminal plate and sealingly engages with the manifold. The sealing engagement between the manifold and the corrosion resistant member prevents fluid flowing through the manifold to the fuel cell stack from contacting the terminal plate. Thus, a fuel cell assembly according to the present invention can be operated while preventing a fluid flow through the manifold from contacting the terminal plate.
