An integrated coolant bottle assembly includes a reservoir configured for use in a thermal system. Examples of such thermal systems include a cooling/heating system of a battery powered electric vehicle, electric power generators (e.g., motor-based systems), other physical plant installations, etc. Such a reservoir includes a first section and a second section. The second section is joined to the first section at a reservoir interface thereby forming the reservoir that is configured for storage and/or flow of a liquid medium. The first section may include an integrated channel that provides a pathway for the flow of the liquid medium. The reservoir may also include a component interface configured to facilitate connection of a component thereto (e.g., a pump, a battery pump, a powertrain pump, a chiller, a heater, a filter, an aerator, a valve, a connector, a fan, or a radiator).

A battery system for an electric vehicle includes a first battery module with a first heater and a second battery module with a second heater. The battery system also includes a control system configured to selectively activate the first or the second heater to dissipate energy from the first or the second battery module.

A system includes an on-board charger that receives energy from an external power source and a battery having a state of charge (SOC) and a battery temperature. The system also includes a battery heater that converts electrical energy into thermal energy (heat) for increasing the battery temperature. The system also includes a battery management system (BMS) that determines or detects a current SOC of the battery and a current battery temperature. The system also includes an electronic control unit (ECU) coupled to the on-board charger and to the BMS. The ECU controls the on-board charger to distribute energy to the battery and to the battery heater to cause the SOC to remain above a SOC threshold and to cause the battery temperature to remain above a battery temperature threshold based on the current SOC and the current battery temperature.

Temperature conditioning unit (10) includes impeller (110), rotary drive source (200), fan case (120), housing (300), intake-side back-end chamber (311a), intake-side front-end chamber (311d), and isolation wall (311). Intake-side back-end chamber (311a) adjoins an object to be temperature-conditioned. Intake-side front-end chamber (311d) is where the air flows in from outside and flows out toward the intake-side back-end chamber. Isolation wall (311) separates intake-side back-end chamber (311a) from intake-side front-end chamber (311d).

Temperature conditioning unit (10) includes impeller (110), rotary drive source (200), fan case (120), housing (300), and at least one of intake side chamber (311a) at an object to be temperature conditioned and an exhaust-side chamber at the object to be temperature-conditioned. Impeller (110) has substantially disk-shaped impeller disk (112) that includes a rotating shaft in its center and is disposed on a plane perpendicular to the rotating shaft, and a plurality of rotor vanes (111) erected on an intake-hole-end surface of impeller disk (112). Rotary drive source (200) includes shaft (210) and is connected to impeller (110) via shaft (210). Fan case (120) has substantially cylindrical side wall (121) formed to be centered about the rotating shaft, intake hole (122) that is circular on a plane perpendicular to the rotating shaft and is centered about the rotating shaft, and discharge hole (123) positioned on an opposite end of the side wall from intake hole (122) in a direction along the rotating shaft. Housing (300) includes an outer surface mounted with fan case (120) and accommodates the object to be temperature-conditioned.

An electrical storage device heater system according to an exemplary aspect of the present disclosure includes, among other things, an electrical storage device, a heater configured to regulate a temperature of the electrical storage device and a controller configured to actuate the heater using power sourced from a location separate from the electrical storage device.

A battery thermal management system for a vehicle having a drivetrain. The thermal management system includes: a high-voltage propulsion battery, a waste-heat source of the vehicle drivetrain, and a battery heating circuit configured for circulating a battery coolant. The battery heating circuit includes a pipe being routed in the vicinity of, and spaced-apart from, the waste-heat source and configured for conveying the battery coolant for enabling the battery coolant within the pipe to heat-up by heat-radiation emitted from the waste-heat source and/or heat-convection through air from the waste-heat source to the battery coolant, and the battery heating circuit is configured for conveying the heated battery coolant to the battery for enabling heating of the battery by the battery coolant.

A vehicle includes an electrical device, a frame member configured to hold the electric device, and a bracket connecting a vehicle structural member and the frame member. The frame member includes: a frame main body having an electrical device accommodation portion configured to accommodate the electrical device and a bracket attachment portion to which the bracket is attached; and an upper frame which is attached to the frame main body and covers the electric device accommodated in the electric device accommodation portion. The bracket attachment portion is attached to the bracket in a direction from the bottom to the top. The upper frame is attached to the frame main body in a direction from the top to the bottom.

A thermal management system comprises two pumps and three coolant loops. The loops are interconnectable such that most if not all of the functions of the thermal management system can be accomplished with one of the two pumps deactivated or inoperable. The thermal management system is selectively configurable to utilize waste heat from a battery, an electrical drivetrain system, and/or a wireless charger to heat cabin air. The thermal management system is further selectively configurable to heat or cool a battery, to cool an electrical drivetrain system, and to cool a wireless charger.

Methods and systems are provided for improving the operating range of an electric vehicle having an engine wherein waste heat generated during motor operation is transferred to pre-heat the engine. Engine starting is predicted based on the electrical torque demand of the vehicle relative to the actual and predicted electrical energy consumption of the electric vehicle. Prior to starting the engine to charge a battery of the motor, various engine components are pre-heated in an order that improves vehicle range while also optimizing fuel economy.
