Patent number: 11807074Abstract: A thermal management system for a vehicle includes a plurality of fluid flow circuits including a heating ventilation and air conditioning (HVAC) circuit circulating a flow of refrigerant therethrough and including an evaporator, a chiller heat exchanger, a first expansion valve located upstream of the evaporator, a second expansion valve located upstream of the chiller heat exchanger, and a heat exchanger located fluidly upstream of the expansion valves. A propulsion cooling circuit circulates a flow of coolant therethrough which is utilized to condition one or more propulsion components of the vehicle. The flow of coolant is directed through the heat exchanger, thus subcooling the flow of refrigerant. A controller is operably connected to one or more control points of the thermal management system and is configured to adjust the one or more control points to achieve a target amount of subcooling of the flow of refrigerant at the heat exchanger.Type: GrantFiled: December 20, 2021Date of Patent: November 7, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Michael H.

Patent number: 11152653Abstract: A system and method for managing thermal energy of a vehicle having a battery and an electric propulsion system are provided. The system monitors a current battery temperature, calculates an actual average battery temperature, and compares the calculated actual average battery temperature to a target lifetime battery temperature. If the actual average battery temperature is greater than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system cools the battery to below the current battery temperature. However, if the actual average battery temperature is less than the target lifetime battery temperature, and the current battery temperature is greater than the target lifetime battery temperature, the system delays cooling the battery. Therefore, the system may avoid expending energy to cool the battery in certain conditions.Type: GrantFiled: April 23, 2019Date of Patent: October 19, 2021Assignee: GM Global Technology Operations LLCInventors: Michael H. Carlson, Eugene V. Gonze, Lawrence P. Ziehr, Tanner E. Goeson, Kyle Holihan, Cameron Smith, Michele Bilancia

Publication number: 20210226276Abstract: A method of controlling temperature of a coolant supplied to a battery pack includes detecting a request for charging the battery pack, and commanding, via the electronic controller, a rate of charge of the battery pack. The method also includes determining the dew point inside the battery pack during the charging. The method additionally includes commanding a supply of coolant to the battery pack while the battery pack is charging. The method also includes regulating a temperature of the coolant to maintain the battery pack above the determined dew point during the charging. The method may further include maximizing the rate of charge at the regulated temperature of the coolant. A battery system employing an electronic controller configured to perform such a method, and a motor vehicle using such a battery system are also within the scope of the present disclosure.Type: ApplicationFiled: January 20, 2020Publication date: July 22, 2021Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Kris Sevel, Orlando Ward-Santos, Kyle Holihan, Andrew M.

Patent number: 10953726Abstract: A method for managing thermal energy of a vehicle having a battery and an electric propulsion system is provided. The system monitors a current battery temperature, after the vehicle is connected to an outside power source at a plug time, and determines an outside air temperature. The system predicts a cabin heating temperature for a subsequent drive cycle. The subsequent drive cycle occurs when the vehicle is no longer connected to the outside power source. If the predicted cabin heating temperature is greater than the outside air temperature, the system heats the battery to a thermal storage temperature that is greater than a target operating temperature of the battery. Therefore, thermal energy is stored within the battery, and may be transferred to heat the cabin.Type: GrantFiled: April 23, 2019Date of Patent: March 23, 2021Assignee: GM Global Technology Operations LLCInventors: Michael H.

Publication number: 20130218724Abstract: Vehicle ownership impact evaluations are implemented by a host system having logic executable thereon. The logic calculates mileage indicative of a roundtrip for a commute received from a user. The logic also acquires terrain data for the commute from a database containing topological information. The logic uses the routing information, in conjunction with a timestamp associated with input from the user, to access a database containing climate information for a geography identified from the routing information, and determines an estimated climate for a time of year via the timestamp. The logic receives an identifier for a vehicle from the user, and retrieves specification data for the vehicle via the identifier. The logic further applies the specification data to the mileage, the estimated climate, the terrain data, and a base energy price, and calculates estimated costs for the commute in terms of energy consumed for the round trip by the vehicle.Type: ApplicationFiled: February 21, 2012Publication date: August 22, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Brunno L.
