Problems solved by technology

It is desirable to reduce or eliminate supplemental HVAC systems that can be used to heat and cool the battery pack, as these separate HVAC systems can add cost and weight and pose packaging issues for these vehicles
[0004] The battery-only range of these vehicles may also be reduced due to the energy requirements of heating or cooling the passenger compartment

Embodiment Construction

[0022] reference Figure 1 to Figure 2 In the figure, a vehicle with a general landmark 20 is shown, and the vehicle 20 has a passenger compartment 21. The vehicle may be, for example, an electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, or a fuel cell vehicle. The vehicle 20 includes a heating, ventilation, and air conditioning (HVAC) and battery thermal management system 22. The thermal management system 22 includes an HVAC part 24 and a battery part 26.

[0023] The HVAC section 24 includes an HVAC module 28 that communicates with and is controlled by the HVAC controller 30 (the communication line is indicated by the dashed line). The HVAC module 28 includes an outside air inlet 32, from which air can be drawn into the outside air inlet 32 ​​and from the atmosphere into the vehicle (typically, the vehicle hood, as indicated by arrow 33), and a recirculating air inlet 34, from which air is drawn from the passenger compartment. 21 is sucked into the c...

Abstract

A HVAC and battery thermal management system for a vehicle havs a HVAC portion and a battery portion, and a method of operation, is disclosed. The HVAC portion may include a main chamber, an evaporator located in the main chamber, a heater extending across a portion of the main chamber downstream of the evaporator, a battery duct extending from the main chamber adjacent to the heater and in fluid communication with the main chamber both upstream and downstream of the heater. The battery portion may include a battery pack in fluid communication with the battery duct, a battery cooling valve located in the battery duct and configured to selectively allow fluid flow from the main chamber between the evaporator and the heater, and a battery heating valve located in the battery duct and configured to selectively allow fluid flow from the main chamber downstream of the heater.

Description

Technical field [0001] The present invention generally relates to a vehicle having a heating ventilation and air conditioning (HVAC) system and an air cooling / heating battery pack. Background technique [0002] Some modern cars are propelled by electric motors. They are hybrid electric vehicles, pure electric vehicles, or some other similar types of vehicles. These vehicles include battery packs used to store the charge used to drive the motors. Significant amounts of energy flowing into and out of the battery pack may occur, which may raise the temperature of the battery pack above the desired level. Likewise, the battery performs better when it is above a certain low temperature range. Therefore, some of these vehicles use multiple technologies to cool and heat the battery pack. Due to the additional cost and complexity of cooling the battery pack, it is desirable to cool and heat the battery pack in the most effective and cheapest way. [0003] In addition, for these vehicles,...
