20090051325 | AUTOMOTIVE POWER SYSTEM AND METHOD OF CONTROLLING SAME - A power source is electrically connected with a battery and an electrical load. The power source has an output voltage and provides current for the battery and electrical load. A charging voltage for the battery is determined based on temperature of the battery. An offset voltage is determined based on the provided current to the battery. The output voltage is determined based on the charging and offset voltages. | 02-26-2009 |
20100187904 | Centralized HV Interlock System - A centralized high voltage interlock system includes an electrical source, an interlock control unit electrically connected to the electrical source, at least one high voltage component disposed in direct electrical contact with the interlock control unit and a high voltage electrical interlock disposed in electrical contact with the at least one high voltage component. | 07-29-2010 |
20110010126 | HIGH VOLTAGE INTERLOCK STRATEGY - A High Voltage Interlock Strategy (HVIS) uses feedback current to detect cable connectivity status for a high-voltage cable configured to connect a power conversion circuit with a remote permanent magnet synchronous machine (PMSM). One or more feedback factors are calculated based on detected feedback current. Various algorithms for calculating a feedback factor, and for determining connectivity status based on calculated feedback factors, can be practiced, according to the PMSM operational mode. Fault detection action can be performed in response to detecting a cable disconnect. The HVIS can be implemented by software, making it a safe, economical solution for cable connectivity detection. | 01-13-2011 |
20110013322 | AUTOMOTIVE VEHICLE CHARGE PORT WITH FAULT INTERRUPT CIRCUIT - An automotive vehicle includes a charge port integrated with the vehicle. The charge port includes electrical contacts configured to receive electrical power from an electric grid, and a fault interrupt circuit electrically connected with the electrical contacts. | 01-20-2011 |
20110162897 | VEHICLE SOLAR PANEL ARRAY WITH HIGH VOLTAGE OUTPUT - An automotive vehicle may include a plurality of solar cells electrically connected to form a solar panel array having a minimum output voltage at a specified standard solar irradiance. The vehicle may also include a battery pack having an output voltage at least equal to the minimum output voltage of the array and configured to provide energy for moving the vehicle. The vehicle may further include a controller configured to selectively electrically connect the array and battery pack to trickle charge the battery pack. | 07-07-2011 |
20110163710 | VEHICLE POWER SYSTEM - A vehicle may include an electric machine, a traction battery, and a solar panel array. The vehicle may further include circuitry electrically connected with the battery and array. The circuitry may include at least one switch configured to close when activated by a calibrated maximum holding power to permit energy to flow from the array to the battery. | 07-07-2011 |
20140205870 | Battery Pack - A battery pack for a vehicle may include a cell array defining an upper surface and a housing defining a raised portion extending along and above a length of the array such that the raised portion and upper surface define a vent manifold therebetween which may be configured to collect gases generated by the array. The housing may define a discharge opening configured to allow gases to exit the manifold. A pair of end plates may be disposed at opposing ends of the array. One of the end plates may define a pass through portion in at least partial registration with the discharge opening. An outlet tube may be configured to facilitate fluid communication between the vent manifold and exterior of the vehicle. The battery pack may also include spacers located between upper edges of adjacent cells and may be configured to prevent cooling gases from entering the vent manifold. | 07-24-2014 |
20150217655 | VERTICAL WIRELESS POWER TRANSFER SYSTEM FOR CHARGING ELECTRIC VEHICLES - A park assist system may, in response to receiving a signal indicating that a remote inductive charge source is within a vicinity of a vehicle, transition from a park assist mode to a wireless charging mode. During the wireless charging mode, the park assist system generates instructions to assist a driver in positioning the vehicle relative to the inductive charge source. | 08-06-2015 |
