A Hybrid-Lite system for use with a vehicle includes a prime mover, an electric power system, and auxiliaries. The prime mover comprises an internal combustion engine. The electric power system is configured to be driven by the combustion engine to produce electric energy for powering the auxiliaries.

This patent application is directed to thermal management systems of vehicles with an electric powertrain. More specifically, the battery system and one or more powertrain components and/or cabin climate control components of a vehicle share the same thermal circuit as the battery module through which heat can be exchanged between the battery module and one or more powertrain or climate control components as needed.

A battery pack is provided including: a plurality of battery cells arranged in multiple battery cell rows; one or more heat exchange spaces; and a device for providing heat exchange to the battery pack. Further, the device includes a heat conduction medium passage arranged in the heat exchange spaces, such that the heat conduction medium passage surrounds multiple battery cells each battery cell row. The heat conduction medium passage is provided with at least a first group of channels and a second group of channels, which are in contact with the surface of each battery cell, and a heat conduction medium is provided in the first group of channels and the second of channels. The heat conduction medium flows in the first group of channels in a direction opposite from the flow of the heat conduction medium in the second group of channels.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

The heat conduction medium passage is provided with at least a first group of channels and a second group of channels, which are in contact with the surface of each battery cell, and a heat conduction medium is provided in the first group of channels and the second group of channels. The heat conduction medium flows in the first group of channels in a direction opposite from the flow of the heat conduction medium in the second group of channels.

The present disclosure relates to a thermal dissipation system of an electric vehicle that includes: a heat exchanger arranged at the front part of the electric vehicle for providing heating or cooling to an air conditioning system of the electric vehicle; a first heat sink and a second heat sink, which are respectively arranged at the two sides of the front part of the heat exchanger; a number of rotatable and adjustable air deflectors for changing the flow direction of the air flowing through the heat dissipation system. Temperature sensors are included within the thermal dissipation system for sensing the working temperatures and the environmental temperatures of a battery pack and a motor of the electric vehicle. Opening and closing states of the air deflectors are adjusted in accordance with data provided by the temperature sensors.

A vehicle body structure includes spaced roof rails and a structural air duct. The air duct has at least two bows connecting between the roof rails and defining first and second channels. An interconnecting member is connected between the bows and defines a third channel connecting the first and second channels in fluid communication with each other. At least one of the bows defines an outlet port configured to supply air to a cabin.

An airflow control assembly for an HVAC system of a work vehicle includes a body having a first inlet configured to receive a first airflow, a second inlet configured to receive a second airflow, and an outlet configured to output a third airflow. The airflow control assembly also includes an arcuate door disposed within the body. The arcuate door is configured to rotate relative to the body to control the first airflow through the first inlet and the second airflow through the second inlet. In addition, a width of the first inlet increases from a first circumferential end of the first inlet to a transition point between the first circumferential end and a second circumferential end of the first inlet, and the width of the first inlet decreases from the transition point to the second circumferential end of the first inlet.

A vehicle includes a floor panel, a battery module, an exhaust duct, and a carpet. The battery module is disposed inside a vehicle interior. The exhaust duct is provided on the floor panel to discharge air output from the battery module through the exhaust duct. The carpet is disposed on the floor panel so as to cover the exhaust duct. The carpet has ventilation holes such that air discharged from the exhaust duct is to pass through a space between the floor panel and the carpet and to be discharged into the vehicle interior through ventilation holes.
