    摘要： A device for performing electrochemical analysis of electrochemical cells includes a housing, upper and lower stack holders, and first, second, and third current collectors. The housing includes an inner chamber that can be hermetically sealed and a central axis extending through the inner chamber. The upper and lower stack holders are disposed within the inner chamber and cooperate to define an electrode stack chamber for housing a negative electrode, a positive electrode, and a center-mounted reference electrode. The first, second, and third current collectors are at least partially disposed in the inner chamber. The first current collector can be electrically connected to a first side of the negative electrode and an external circuit. The second current collector can be in electrical contact with the positive electrode and the external circuit. The third cylindrical body can be in electrical contact with the center-mounted reference electrode and the external circuit.

    摘要： In a vehicle, a first energy storage device has a first direct current (DC) operating voltage; and a second energy storage device has a second DC operating voltage. The second DC operating voltage is greater than or less than the first DC operating voltage the first DC operating voltage. A switch is connected between the first and second energy storage devices. A fault diagnostic module, while an internal combustion engine of the vehicle is shut down, diagnoses that a fault is present when a voltage of the first energy storage device is less than a predetermined DC voltage. The predetermined DC voltage is less than the first DC operating voltage. A switch control module closes the switch when the fault is diagnosed. A starter control module, when the fault is diagnosed, applies power to a starter from the second energy storage device via the switch.

    摘要： A reference structure and a separator assembly is provided. The separator assembly provides a base layer, a first contact, an optional second contact and a reference component which may be implemented in various applications. The base layer includes a first side and a second side. The first contact is affixed on the first side of the base layer between the base layer and an anode. The second contact is affixed on the second side of the base layer. A reference component is affixed to the second side of the base layer and the optional second contact, if implemented. The reference structure includes a semi-permeable reference component affixed or coupled to a base element.
