Described herein are devices, systems, and methods for managing the power consumption of an automotive vehicle, and thereby for optimizing the power consumption of the vehicle. The devices and systems for managing the power consumption of the vehicle typically include power management logic that can calculate an applied power for the vehicle engine based on information provided from the external environment of the vehicle, the operational status of the vehicle, one or more command inputs from a driver, and one or more operational parameters of the vehicle.

An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.

A vehicle is provided. The vehicle includes an engine, an electric machine, an electric heater, and a controller. The electric machine is configured to recharge a battery through regenerative braking. The electric heater is configured to heat an engine coolant. The controller is programmed to redirect regenerative braking power to the electric heater in response to the engine coolant temperature being below a threshold.

In an operation mode for heating battery air, a refrigerant passage switching portion switches over to a first refrigerant passage in which a refrigerant including gas refrigerant flowing out of an interior condenser flows into an auxiliary heat exchanger through a first pipe having a relatively large passage cross-sectional area and a liquid refrigerant flowing out of the auxiliary heat exchanger flows to an inlet of an exterior heat exchanger through a second pipe having a relatively small passage cross-sectional area. Meanwhile, in an operation mode for cooling the battery air, the refrigerant passage switching portion switches over to a second refrigerant passage in which a liquid refrigerant flowing out of the exterior heat exchanger flows into the auxiliary heat exchanger through the second pipe and a gas refrigerant flowing out of the auxiliary heat exchanger flows to a suction port of a compressor through the first pipe.

A vehicle includes an engine, a rotary electric machine, an electric storage device, and a controller. The rotary electric machine is connected to an output shaft of the engine. The electric storage device is configured to supply electric power to a drive source of the vehicle and to be charged with electric power from an external power source. The external power source is disposed outside the vehicle. The controller is configured to supply the electric power from the external power source to the rotary electric machine such that the output shaft is rotated when the electric storage device is chargeable with the electric power from the external power source.

A method is provided for estimating range per full charge (RPC) for a vehicle. The method includes a controller which may, in response to detecting presence of a predefined condition impacting vehicle energy consumption, output to an interface by a controller a RPC and indicia indicative of an extent to which the predefined condition is affecting the RPC. An electrified vehicle including one or more vehicle components, a traction battery to supply energy to the vehicle components, one or more sensors, and a controller is also provided. The one or more sensors monitor the vehicle components, traction battery, and preselected ambient conditions. The controller is configured to, in response to input from the sensors, generate output for an interface which includes a RPC and indicia indicative of an extent of impact on the RPC by each of the ambient conditions and operation of the components and battery.

A vehicle includes an engine, a climate control system, a cabin, and a controller. The controller is programmed to, in response to the climate control system supplying heat to a vehicle cabin and receiving a request for an economy mode, decrease an engine coolant temperature engine start threshold. The controller is further programmed to, in response to the engine coolant temperature becoming less than the threshold, start the engine.

Various methods and systems are provided for an auxiliary power unit. In one embodiment, an auxiliary power unit comprises a plurality of independent modules configured to be installed in respective different locations within a rail vehicle or other vehicle. Each module of the plurality of independent modules is configured to carry out one or more respective functions of the auxiliary power unit for providing auxiliary power in the vehicle.

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.

An ECU sets a voltage of an inverter side in an external supply mode to be less than a voltage of the inverter side when a first MG supplies the electric power equal to the electric power in the external supply mode in a traveling generation mode.
