摘要： A thermal management system for an electrified vehicle and a method for managing such a system, includes a coolant subsystem to cool a battery pack and a refrigerant subsystem. The coolant subsystem includes a battery chiller in fluid communication with a cooling system inlet to the battery pack. The refrigerant subsystem includes a chiller cooling subsystem to cool the battery chiller and a cabin cooling subsystem to cool a passenger cabin, wherein the chiller cooling subsystem and the cabin cooling subsystem are completely separate from each other.

摘要： A power converter for an electric vehicle include a connection interface for coupling an external battery to a first bus. The power converter includes a first set of switching devices configured to transfer power between a charge port and the first bus, and a second set of switching devices configured to transfer power between the first bus and a second bus coupled to a traction battery. The power converter includes a controller programmed to control a voltage level of the first bus to different nominal operating voltages based in different operating modes.

摘要： An electrified vehicle, system, and method include an electric machine, a traction battery coupled to the electric machine, and a controller programmed to control wheel slip to provide high wheel slip to traverse deformable terrain, such as sand or loose soil, and lower wheel slip to avoid excessive soil removal beneath the wheels after detecting a vertical acceleration or heave event, such as after landing when driving over a jump or bump. When vehicle vertical acceleration exceeds a first threshold, and a ratio of a wheel angular acceleration to vehicle longitudinal acceleration exceeds a second threshold, the electric machine is controlled to limit wheel slip to a lower value that provides sufficient tractive force to maintain some forward motion. Otherwise, the electric machine is controlled to limit wheel slip to a higher value to accommodate higher vehicle speeds over the deformable terrain.

摘要： A traction battery assembly includes, among other things, battery cells configured to be positioned between a first frame rail of an electrified vehicle and an opposite, second frame rail of the electrified vehicle. The battery cells are arranged to transfer a load from the first frame rail to the second frame rail. A method of securing battery cells includes, among other things, positioning battery cells between a first frame of an electrified vehicle and an opposite, second frame rail of the electrified vehicle. The battery cells are positioned to transfer a load from the first frame rail to the second frame rail.

摘要： This disclosure describes charging systems for electrified vehicles. Exemplary charging systems may employ a multi-voltage charging circuit that supports charging of a traction battery pack at both a first voltage level during a first charging condition and a second, different voltage level during a second charging condition. Higher voltage levels may be experienced during the second charging condition as compared to the first charging condition.

摘要： This disclosure details thermal management systems for thermally managing battery packs and other electric drive components of electrified vehicles. An exemplary thermal management system may include a battery cooling circuit and an e-drive cooling circuit. The e-drive cooling circuit may be fluidly connected to the battery cooling circuit by a combination of valves and coolant lines during or in anticipation of certain vehicle conditions, such as high load operating conditions, to augment cooling of electric drive components during the high load operating conditions.
