    摘要： A pre-charge system for a DC electric power system includes a high-voltage electric power bus that electrically connects to an external bus. A contactor includes a first switch arranged to control electric power through the positive bus link, and a second switch arranged to control electric power through the negative bus link. A pre-charge resistor is arranged in parallel with the first switch. A controller is operatively connected to the first and second switches, and in communication with a voltage sensor. The controller includes an instruction set to activate the second switch, periodically monitor the electrical potential, determine a time-rate of change in the electrical potential, and close the first switch when the time-rate of change in the electrical potential is less than a first threshold.

    摘要： A system for transferring DC electric power to a DC electric power system includes an electric power source, a DC-DC power converter, a system power bus including a capacitor, a first current sensor, a second current sensor, a third current sensor, and a controller. The DC-DC power converter includes a switched inductance circuit including an inductor, a high-voltage switch, and a diode. The second current sensor monitors a second current in the system power bus between the DC-DC power converter and the capacitor. The controller determines a parametric setpoint for the system power bus, determines the first current, the second current, and the third current in the system power bus, and controls the switching DC-DC power converter based upon the parametric setpoint, the first current, the second current, and the third current.

    摘要： A system and method are described for maintaining a recharging station database for electric vehicles based upon recharging event data provided by electric vehicles equipped with telematics units. The recharging station server computer system is configured to receive recharging event information corresponding to a recharging event for an electric vehicle battery unit by an identified recharger, the recharging event information including at least a measurement relating to an electrical infrastructure providing power to the identified recharger. The system is further configured to process the recharging event information to render a diagnostic result relating to an electrical infrastructure providing power to the identified recharger. The computer system issues an alert based upon a detected condition in the electrical infrastructure during the processing.
