Abstract: Disclosed are a fuel cell stack sensor and a method of operating the same. The fuel cell stack sensor has a structure capable of measuring a temperature, a humidity, and a hydrogen concentration inside and outside of a fuel cell stack enclosure including a fuel cell stack by using at least two or more substrates inside the sensor. The fuel cell stack sensory may also determine whether: there is a hydrogen leak and the concentration of the leaked hydrogen; whether there is a leak inside the fuel cell stack enclosure; and whether the fuel cell stack sensor itself is poisoned by volatile organic compounds.

Abstract: An electric vehicle power train can advantageously combine two core technologies, a coil driver system and a power source (e.g., battery) control system (e.g., BCS) to demonstrate several system-level benefits. An electric vehicle power train can advantageously combine two core technologies, a coil driver system and a power source (e.g., fuel cell) control system to demonstrate several system-level benefits. An electric vehicle power train can advantageously include a battery and a BCS along with a fuel cell system. An electric vehicle power train can advantageously include a battery and a BCS without a fuel cell system. An electric vehicle power train can advantageously include a fuel cell system without a battery or a BCS. The coil driver system can implement, for example, two torque profiles within one electric machine by switching stator packs between a series arrangement of coils or windings and a parallel arrangement of coils.

Abstract: The invention relates to an interconnection device for interconnecting several fuel cell modules. A base element is provided therein, which provides a matrix of contact points, which can be equipped with connecting elements for implementing different interconnections. The base element has two input connections and output connections for each fuel cell module to be connected. Further, two busbars are provided, each of which is connected to one half of the output connections and each of which provides an external contact for connecting an electrical load to be supplied by the fuel cell modules. For each provided parallel branch of fuel cell modules, a diode device is provided, which is connected between one of the input connections and one of the busbars and allows a current flow only in the direction from the respective input connection to the respective busbar.

Abstract: A method is provided for monitoring the operation of a vehicle powered by a fuel cell and a battery. The method comprises the steps of determining an energy capacity of the vehicle, estimating an energy required for the vehicle to travel on a route to a destination, determining whether the energy required is greater than the energy capacity, and if it is determined that the energy required is greater than the energy capacity, sending a notification to alert a driver of the vehicle.

Abstract: A control device includes a first accumulation unit configured to accumulate first energy, a second accumulation unit configured to accumulate second energy different from the first energy, and a supply unit configured to supply either or both of second energy obtained by converting first energy accumulated by the first accumulation unit and second energy accumulated by the second accumulation unit to an external device. The amount of second energy that is supplied from the supply unit to the external device is calculated on the basis of the amount of second energy supplied to a drive unit via the supply unit to move the moving body to a destination, the amount of first energy accumulated by the first accumulation unit, and the amount of second energy accumulated by the second accumulation unit, and a display device is caused to display a supply available time according to the calculated amount of second energy.

Abstract: A system for monitoring a battery module having a plurality of cells includes a sensor adapted to obtain respective cell voltages of the plurality of cells. The controller is adapted to receive data from the sensor, the controller having a processor and tangible, non-transitory memory on which instructions are recorded. The controller is configured to sort the respective cell voltages to create a voltage ranking. The voltage ranking is repeated with at least one new set of cell voltage readings obtained at a predefined checking frequency. Differences in the voltage ranking of the plurality of cells are analyzed. The controller is adapted to control operation of the battery module based in part on differences in the voltage ranking. The controller may be adapted to predict likelihood of a thermal runway event based in part on the differences in the voltage ranking.

Abstract: A control system for off-highway battery application powertrain systems that allows the operator to select one or more performance/operating modes. The one or more performance modes may be based on the work that needs to be accomplished using the machine vs. the hours needed before the next charge opportunity. Modes will take typically into consideration battery management system performance maps, Electric motor/inverter performance maps, pump performance maps and other systems communicating with the powertrain system. The operator is in control to optimize refill and/or next battery charge. The operator may have the option to select performance modes based on excavator performance vs. battery life. Remaining time and warning messages may be periodically sent to the operator based on the performance mode selected and current state of charge.

Abstract: An EV service station is provided. The EV service station includes a hydrogen storage tank configured to supply hydrogen to a hydrogen fuel cell unit. The hydrogen fuel cell unit converts hydrogen into electrical power so as to charge a battery bank. A power control unit draws power from the battery bank to a power outlet configured to couple with an EV so as to charge the EV. As hydrogen is provided for charging operations, the EV service station is not reliant upon electricity from a utility provider such as a commercial power grid.
