20080271937 | SYSTEM AND METHOD FOR POWERING A POWER CONSUMING VEHICLE ACCESSORY DURING AN OFF STATE OF THE VEHICLE - A hybrid battery system of an automotive vehicle provides power to various features without running an internal combustion engine. | 11-06-2008 |
20090278500 | AUTOMOTIVE POWER SUPPLY SYSTEM AND METHOD OF OPERATING SAME - A battery control module monitors discharge voltages associated with a traction battery of an automotive vehicle. The battery control module cycles the traction battery at a discharge-voltage dependent charge/discharge profile to generate heat within the traction battery. | 11-12-2009 |
20130034767 | BATTERY PACK LIQUID COOLING SYSTEM - A cooling system operable to cool a battery pack or other device through a heat exchange operation supported, at least in part, with cycling of a coolant relative to a coldplate or other thermally conducting surface of the device and/or attached thereto. | 02-07-2013 |
20150028808 | Method to Estimate Battery Open-Circuit Voltage Based on Transient Resistive Effects - A vehicle is disclosed that includes a battery and a controller programmed to calculate a battery voltage characteristic from previously measured charge and discharge data. The battery voltage characteristic is based on differences between the previously measured values when state of charge falls in a range in which the differences are approximately equal. Outside of the range, the charge and discharge voltage data are corrected based on a square root of time to obtain the battery voltage characteristic. The characterization may be performed with a high-rate continuous charge and discharge cycle. Also disclosed is an apparatus for generating the battery characteristic that includes a bi-directional power supply. The battery voltage characteristic is obtained based on the differences of the charge and discharge voltage data and corrected data based on the square root of time. A method is also disclosed based on the same. | 01-29-2015 |
20150063404 | BATTERY PACK LEAK DETECTION ASSEMBLY AND METHOD - A method of detecting a leak in a battery pack according to an exemplary aspect of the present disclosure includes, among other things, calculating a predicted amount of thermal energy at a position, measuring an actual amount of thermal energy at the position, and comparing the predicted amount to the actual amount to identify if a battery pack is leaking. | 03-05-2015 |
20150065026 | CABIN VENTING SYSTEM AND METHOD FOR AN ELECTRIFIED VEHICLE - A method according to an exemplary aspect of the present disclosure includes, among other things, detecting a battery fault of a battery of an electrified vehicle, activating a HVAC system ON, commanding the HVAC system to a fresh air mode, communicating fresh air into a passenger cabin, and expelling battery vent byproducts from the passenger cabin through at least one air extractor vent during key-on or key-off states. | 03-05-2015 |
20150066262 | IN-RANGE CURRENT SENSOR FAULT DETECTION - A current sensor fault detection system is disclosed which enables detection of a current sensor fault while the current sensor is operating and providing a current sensor output which is within a normal operating range. The current sensor is monitored by at least one controller which compares a change in battery state of charge error with a predetermined threshold. The change in battery state of charge error is a difference between a first change in battery state of charge calculated by integrating battery current with respect to a time and a second change in battery state of charge calculated based on the battery open circuit voltage during the time. | 03-05-2015 |
20150191098 | METHOD AND SYSTEM FOR EXTENDING BATTERY LIFE - A method for extending the life cycle of a battery includes receiving a storage mode status signal at a battery controller and incrementally adjusting a state of charge window over a period of time in response to receiving the storage mode status signal. | 07-09-2015 |
