20140266038 | METHOD AND SYSTEM FOR CONTROLLING AN ELECTRIC VEHICLE WHILE CHARGING - A vehicle includes a traction battery having a thermal circuit, and a controller. The controller is configured to: (i) charge the traction battery using a maximum charging current defined by the lowest temperature cell while the traction battery is connected to the charger, and (ii) heat the traction battery if the lowest temperature cell is below a predetermined temperature while the traction battery is charging. A method for controlling an electric vehicle while connected to a charger includes charging the battery using a first portion of power from the charger while heating the battery using a second portion of power from the charger in response to a low cell temperature in a traction battery. | 09-18-2014 |
20140277869 | METHOD AND SYSTEM FOR CONTROLLING AN ELECTRIC VEHICLE WHILE CHARGING - An electric vehicle has a thermal circuit connected to a traction battery and a cabin climate system, a user interface, and a controller. The controller is configured to charge the traction battery to a target state of charge, condition the traction battery to a target battery temperature, and condition a vehicle cabin to a target cabin temperature based on a charging profile based on the user input in response to receiving a user input requesting vehicle conditioning from the user interface and the traction battery being connected to an external power source. A method for controlling an electric vehicle while connected to an external power source includes charging a traction battery to a target state of charge and conditioning the battery to a target temperature according to a charging profile based on a user initiated request for vehicle conditioning. | 09-18-2014 |
20150064516 | FLEX CIRCUIT SYSTEM FOR A BATTERY ASSEMBLY OF AN ELECTRIFIED VEHICLE - A flex circuit system according to an exemplary aspect of the present disclosure includes, among other things, a substrate, at least one bus bar mounted to the substrate and at least one voltage sense lead integrated with the substrate. | 03-05-2015 |
20150066416 | SYSTEM AND METHOD FOR TESTING VEHICLE TRACTION BATTERY COMPONENTS - A traction battery connection simulator is disclosed comprising a plurality of power supplies connected to simulate a traction battery and a plurality of switching devices that selectively connect the power supplies to a controller under test. The simulator further comprises a controller programmed to selectively connect at least one of power supplies to the controller under test for a predetermined period of time before connecting remaining power supplies. The controller may also be programmed to disconnect at least one power supplies from the controller under test for a predetermined period of time before disconnecting remaining power supplies. Voltages associated with each power supply and currents through each switching device may be compared to corresponding predetermined ranges. An indicator may be set in response to at least one of the voltages and currents being outside of a corresponding predetermined range. | 03-05-2015 |
