An energy control system for use with an electric vehicle having an energy storage device that powers both the propulsion system of the vehicle and a transport refrigeration unit that is configured to condition a cargo space of the vehicle; the energy control system is configured to receive a user selection relating to energy to be allocated to the propulsion system and/or the transport refrigeration unit; and the energy control system is configured to provide control for an energy allocation of the available energy in the energy storage device between the propulsion system and the transport refrigeration unit based on the user selection and the available energy in the energy storage device.

A vehicle has a thermal management system that comprises an electric power source loop comprising at least one battery. The thermal management system further comprises a heating component thermally coupled to the electric power source loop. When an ambient temperature is less than a first threshold, the heating component pre-heats the at least one battery. In exemplary embodiments, the heating component includes at least one brake resistor that is coupled to the electric power source loop.

A coupled battery and motor controller thermal management system is disclosed. In various embodiments, a motor controller and a heat sink are coupled thermally to a battery. At least a portion of waste heat generated by the motor controller is transferred to the thermal mass of the battery during at least a first mode of operation in which a relatively low amount of ambient air flows through the heat sink.

Embodiments of the present invention are directed to a method and system for preventing ingestion of ambient air contaminated with possibly harmful, toxic, or flammable battery gases into a passenger compartment of a vehicle in the event of a battery failure. If an abnormal state is detected in a battery pack of the vehicle, the vehicle automatically switches the HVAC system to air recirculation mode, thereby preventing any toxic gas emitted from the battery pack from entering the passenger compartment.

During pre-air conditioning in a vehicle cabin, when consumed electric power exceeds use permission electric power while an auxiliary heating device is operating, an operation of the auxiliary heating device is stopped. In contrast, when the consumed electric power exceeds the use permission electric power while the auxiliary heating device is not operating, a rotation speed of an electric compressor of an air conditioner is restricted. Therefore, the temperature environment in the vehicle cabin is improved by continuing the pre-air conditioning of the air conditioner while reducing the consumed electric power by stopping the operation of the auxiliary heating device.

A cooling system is provided for a traction battery of an electrified motor vehicle. That cooling system includes a cooling circuit, a refrigerant circuit, a plurality of flow control valves and a control system. That control system includes a controller configured to (a) control operation of the plurality of flow control valves and (b) prioritize cabin cooling over traction battery cooling.

A system for cooling a vehicle including a power conversion component, a motor, a radiator, an electronic water pump, and a cooling unit cooling the power conversion component includes: an air conditioning unit configured to interlock with the cooling unit to perform air conditioning of the vehicle; a temperature sensor configured to sense a temperature of air in the air conditioning unit; a cooling water temperature sensor configured to sense a temperature of cooling water flowing in the cooling unit; and a cooling control controller configured to calculate a targeted air flow rate and a targeted cooling water flow rate to control the cooling of the cooling unit.

An air conditioner system for mobility is provided. The air conditioner system is configured to secure the air conditioning performance in cooling and heating conditioning and to prevent a battery from being deteriorated as the battery is prevented from being overcharged while the air conditioner system is driven when the battery is charged by the regenerative breaking while the charge amount of the battery is already high.

A powertrain system includes an electric generator, a compressor, a water cooling module including a water pump, an electronic fan, a steering pump, a pneumatic module including an air pump, a transmission device, and an electric motor. The electric motor is configured to drive the electric generator, the compressor, the water pump, the electronic fan, the steering pump, and the air pump to work through the transmission device. The present invention further provides an electric vehicle with the powertrain system.

A heat pump system for a vehicle controls a temperature of a battery module by use of one chiller in which a coolant and a refrigerant are heat-exchanged and that improves heating efficiency by recovering heat from various heat sources in a heating mode of a vehicle to use them for indoor heating, including: a valve, an electrical component cooling device, a battery cooling device, an indoor heating device, an indoor cooling device, a centralized energy device, and a chiller, wherein a condenser included in the centralized energy device is connected to the second line through the second valve to condense the refrigerant supplied through the refrigerant line through heat-exchange with the coolant and is provided in a sixth line through which the coolant flows; and a first end portion of the third line is connected to a third valve provided in the sixth line.
