Description

Technical Field

[0001] The present invention relates to the technical field of vehicle passenger compartment heating, and in particular to a passenger compartment heating system, a vehicle and a heating method based on graphene materials. Background Art

[0002] In traditional vehicle cabin heating systems, the temperature inside the vehicle is usually raised by outputting hot air through the air-conditioning outlet of the vehicle. Although this method can achieve heating inside the vehicle, there are more heat exchanges and heat cycles with the outside of the vehicle, resulting in relatively high heating energy consumption. At the same time, the distribution of hot air is often not uniform, making it difficult to meet the passengers' demand for personalized comfort.

[0003] In vehicles such as electric vehicles that use power batteries as their energy source, the temperature inside the car is usually increased by outputting hot air through the car's air-conditioning outlet. The air-conditioning is also electrically driven, and electrically driven air-conditioning consumes a lot of electricity. In cold areas, it can even reduce the vehicle's range by more than 20%, affecting the car-using experience. At the same time, the air-conditioning heating method heats the car interior through a heat pump system outside the car. There are more heat exchanges and heat cycles with the outside of the car, resulting in relatively high heating energy consumption. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a passenger compartment heating system, vehicle and heating method based on graphene materials, which are mainly aimed at the existing mainstream five-door five-seat vehicles. It solves the technical problem in the prior art that the heat pump system has high heating energy consumption, resulting in poor vehicle experience.

[0006] (II) Technical solution

[0007] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0008] In the first aspect, the present invention provides a passenger compartment heating system based on graphene materials, comprising an automobile interior decoration component, a graphene heating module, a temperature control module, an occupant identification module and a temperature detection module; a connection area is provided on the surface of the automobile interior decoration component facing the passenger compartment; the graphene heating module is detachably and fixedly connected to the connection area; the temperature control module is electrically connected to the graphene heating module, and is suitable for controlling the on-off and temperature of the graphene heating module circuit; the occupant identification module is suitable for identifying occupants on automobile seats; the temperature detection module is suitable for detecting the temperature of a corresponding position of the passenger compartment, wherein, when the temperature detection module detects that the temperature of the corresponding position of the passenger compartment is lower than a threshold value, and the occupant identification module identifies the occupant on the corresponding seat, the graphene heating module corresponding to the occupant position can be turned on to form a heating field for the corresponding occupant.

[0009] In a second aspect, the present invention provides a vehicle, including the passenger compartment heating system based on graphene materials in the above technical solution, and the vehicle includes an electric vehicle.

[0010] In a third aspect, the present invention provides a method for heating a vehicle passenger compartment, which is applied to the vehicle in the above technical solution, and the method comprises:

[0011] S1: Detect the temperature T at the corresponding position of the passenger compartment and the power battery Soc;

[0012] S2: Based on T being less than the threshold and Soc being greater than the threshold, the occupant recognition module is controlled to recognize the passenger.

[0013] S3: Based on the passenger identification module identifying the passenger at the corresponding position, the graphene heating module at the corresponding position is turned on.

[0014] (III) Beneficial effects

[0015] The beneficial effects of the present invention are as follows: the present invention is based on a graphene heating module, combined with temperature sensing and occupant identification technology, to achieve intelligent control of the heating system. Since graphene materials have excellent electrical and thermal conductivity and heating efficiency, and can form a heating field for the occupant position, the present invention is compared to the traditional heating method of outputting hot air through the air-conditioning outlet of the car. Since there is no heat exchange and heat circulation with the outside of the car, the present invention directly provides heat to the occupants through the graphene heating module in the form of thermal radiation and heat conduction, thereby greatly saving heating energy consumption, and thereby reducing the energy consumption of electric vehicles using the system. Since the heating field can be highly matched with the occupant position, the heat can be transferred to the occupant position more directly and efficiently, so a good heating effect can be achieved with lower energy consumption.

[0016] Moreover, since the main method of the graphene heating module is far-infrared radiation, it also has certain therapeutic effects, so the heating comfort is better than the existing air-conditioning heating method.

[0017] Precisely because the graphene heating module is detachably and fixedly connected to the connection area, it can be used as an optional part or a modified part. By reserving the connection area and the power plug at the corresponding position, the graphene heating module can be quickly installed, maintained and replaced.

[0018] The vehicle passenger compartment heating system based on graphene materials in the present invention is particularly suitable for electric vehicles or hybrid vehicles equipped with power batteries as energy sources. In cold weather conditions, the system can flexibly and specifically heat the passenger compartment to provide passengers with a comfortable in-car environment while protecting battery life and improving energy efficiency.

[0041] In order to better explain the present invention, so as to facilitate understanding, the following Figure 1-Figure 12 , the present invention is described in detail through specific implementation methods. Figure 1 The orientation is used as a reference.

[0042] Embodiment 1:

[0043] Reference Figure 1-Figure 10 An embodiment of the present invention provides a passenger compartment heating system based on graphene materials, comprising an automobile interior decoration part 1, a graphene heating module 2, a temperature control module 3, an occupant identification module 4 and a temperature detection module 5; a connection area A is provided on the surface of the automobile interior decoration part 1 facing the passenger compartment; the graphene heating module 2 is detachably and fixedly connected to the connection area A; the temperature control module 3 is electrically connected to the graphene heating module 2, and is suitable for controlling the on-off and temperature of the circuit of the graphene heating module 2; the occupant identification module 4 is suitable for identifying the occupant on the automobile seat; the temperature detection module 5 is suitable for detecting the temperature of the corresponding position of the passenger compartment, wherein, when the temperature detection module 5 detects that the temperature of the corresponding position of the passenger compartment is lower than the threshold value, and the occupant identification module 4 identifies the occupant on the corresponding seat, the graphene heating module 2 corresponding to the occupant position can be turned on to form a heating field 100 for the corresponding occupant.

[0044] The present invention is based on a graphene heating module 2, combined with zoned temperature sensing and occupant identification technology for different passenger compartment positions, to achieve intelligent and refined control of the heating system. Since the graphene material has excellent electrical and thermal conductivity and heating efficiency, and can form a heating field 100 for the occupant position, the present invention is compared to the traditional heating method of outputting hot air through the air-conditioning outlet of the car. Since there is no heat exchange and heat circulation with the outside of the car, the heat is directly provided to the occupants through the graphene heating module 2 in the form of thermal radiation and heat conduction, thereby greatly saving heating energy consumption. Since the heating field 100 and the temperature control method of the heating field 100 can be highly matched with the occupant position, the heat can be transferred to the occupant position more directly and efficiently, so a good heating effect can be achieved with lower energy consumption.

[0045] Furthermore, since the main mode of the graphene heating module 2 is far-infrared radiation, it also has certain therapeutic effects, so the heating comfort is better than the existing air-conditioning heating mode.

[0046] Precisely because the graphene heating module 2 is detachably and fixedly connected to the connection area A, it can be used as an optional part or a modified part. By reserving the connection area A and the power plug at the corresponding position, the graphene heating module 2 can be quickly installed, maintained and replaced.

[0047] The vehicle passenger compartment heating system based on graphene materials in the present invention is particularly suitable for electric vehicles or hybrid vehicles equipped with power batteries as energy sources. In cold weather conditions, the system can flexibly and specifically heat the passenger compartment to provide passengers with a comfortable in-car environment while protecting battery life and improving energy efficiency.

[0048] Specifically, the automobile interior component 1 serves as the installation base of the heating system, and a connection area A is provided on the surface of the interior component facing the passenger compartment. The connection area A is used to fix the graphene heating module 2 to ensure that the heating effect directly acts on the occupants.

[0049] The graphene heating module 2 utilizes the excellent electrical and thermal conductivity of graphene materials to achieve rapid and uniform heating. The module is designed to be detachable for easy installation, maintenance and replacement. It is fixedly connected to the interior parts through the connection area A and heats according to the instructions of the temperature control module 3.

[0050] The temperature control module 3 is electrically connected to the graphene heating module 2 and is responsible for controlling the circuit on / off and temperature of the heating module and accurately adjusting the heating power according to the information of the temperature detection module 5 and the occupant identification module 4 .

[0051] The occupant identification module 4 uses sensors, cameras or other identification technologies to accurately identify the occupants on the car seats, and the identification information is used to trigger the corresponding graphene heating module 2 to achieve personalized heating.

[0052] The temperature detection module 5 continuously detects the temperature of the corresponding positions in the passenger compartment, including the main driving position, the co-pilot position and the rear passenger position, and compares the real-time temperature information with the set threshold. When the occupant enters the car and sits in the seat, the occupant identification module 4 is started to confirm the presence and position of the occupant. The temperature control module 3 receives information from the temperature detection module 5 and the occupant identification module 4.

[0053] When the temperature in the passenger compartment is lower than the threshold value and the passenger identification module 4 identifies the passenger on the corresponding seat, the temperature control module 3 determines that the heating condition is met. After the heating condition is met, the temperature control module 3 instructs the graphene heating module 2 corresponding to the passenger position to turn on, and the graphene heating module 2 quickly heats up to form a heating field 100 for the corresponding passenger.

[0054] The temperature control module 3 detects the temperature of the heating module in real time and adjusts it according to preset conditions or occupant feedback to ensure that the heating temperature is moderate, neither overheated nor insufficient, providing a comfortable riding environment for the occupants.

[0055] When the temperature in the passenger compartment rises above the set value, or when the passenger leaves the seat, the temperature control module 3 instructs the corresponding graphene heating module 2 to shut down to save energy.

[0056] Embodiment 2:

[0057] Reference Figure 1 and Figure 2 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0058] The automobile interior part 1 includes a door panel 11, a glove box 12 and a central channel 13, which are not only components of the automobile interior, but also the installation basis of the heating system. When the graphene heating module 2 on the driver's side door panel 11 and the central channel 13 close to the driver is turned on, a driver thermal field 101 is formed. The thermal field mainly covers the driver's seat area, providing a driving environment with a suitable temperature for the driver.

[0059] When the glove box 12, the door panel 11 on the co-pilot side and the graphene heating module 2 on the central channel 13 near the co-pilot are turned on, a co-pilot thermal field 102 is formed. The thermal field mainly covers the co-pilot seat area, providing a warm riding experience for the co-pilot passenger.

[0060] When the graphene heating module 2 on the door panel 11 on the rear passenger side is turned on, a rear thermal field 103 is formed, which mainly covers the rear seat area, providing a comfortable heating effect for the rear passengers.

[0061] The automobile interior also includes front seats 14, and the rear side walls of the front seats 14 are provided with graphene heating modules 2 facing the rear passengers;

[0062] When the graphene heating module 2 on the door panel 11 on the rear passenger side and the graphene heating module 2 on the rear side wall of the front seat 14 are turned on, a rear thermal field 103 is formed, that is, the composition of the rear thermal field 103 also cleverly utilizes the rear area of ​​the front seat 14, thereby further improving the heating effect of the rear thermal field 103, and at the same time also enables the front part of the body of the rear passengers to receive a large area of ​​heating therapy, thereby further improving the comfort of the rear passengers.

[0063] The control method of the graphene heating module 2 on the front seat 14 is the same as the control method of the graphene module 2 on the rear door panel 11, which will not be described in detail here.

[0064] By combining graphene heating modules 2 in different areas, regional heating in the passenger compartment is achieved, providing a personalized heating experience based on the passenger position and the temperature in the passenger compartment. Since the heating system can be highly targeted to the position of the passenger, the heating is more efficient and energy-saving.

[0065] Embodiment 3:

[0066] Reference Figure 5-Figure 10 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0067] The graphene heating module 2 includes a frame 21 and a body 22, the edge of the body 22 is supported on the frame 21, and the frame 21 is detachably fixedly connected to the connection area A; the body 22 includes a reflective layer 221, a substrate layer 222, a graphene layer 223 and a surface layer 224 stacked in sequence, and the surface layer 224 faces the passenger compartment.

[0068] In this embodiment, the frame 21 serves as a supporting structure for the graphene heating module 2. The design of the frame 21 takes into account the convenience and firmness of installation, ensuring that the heating module will not loosen or fall off during the driving of the car. The body 22 is responsible for generating heat and transferring it to the occupants. The edge of the body 22 is supported on the frame 21 and connected to the automotive interior 1 through the frame 21.

[0069] The body 22 includes a reflective layer 221, a substrate layer 222, a graphene layer 223 and a surface layer 224 stacked in sequence. The reflective layer 221 is located at the bottom layer and is used to reflect heat and improve heating efficiency. The substrate layer 222 serves as a carrier of the graphene layer 223 and provides a stable support structure. The graphene layer 223 is the core heating element of the heating module, which uses the excellent electrical and thermal conductivity of the graphene material to achieve rapid and uniform heating.

[0070] The surface layer 224 is located at the top layer, facing the passenger compartment, radiating heat at a close distance to provide a comfortable heating experience.

[0071] When the temperature control module 3 receives a heating instruction, current passes through the graphene layer 223 to generate heat, and the heat is radiated into the passenger compartment through the surface layer 224 to form a heating field 100. The reflective layer 221 reflects part of the heat back to the substrate layer 222 and the graphene layer 223 to improve the heating efficiency.

[0072] Specifically, the reflective layer 221 can be made of a material with high reflectivity, such as aluminum foil or aluminum-plated film. The main function of the reflective layer 221 is to reflect heat back to the substrate layer 222 and the graphene layer 223, thereby reducing heat loss and improving heating efficiency. By reflecting heat, the reflective layer 221 can ensure that more heat is transferred to the surface layer 224, thereby accelerating the heating speed and reducing energy consumption.

[0073] The substrate layer 222 can be made of polymer materials such as polyester film PET and polyimide film PI. The substrate layer 222 not only provides a stable support structure for the graphene layer 223, but also transfers the heat generated by the graphene layer 223 to the surface layer 224 evenly. At the same time, the substrate layer 222 also needs to have good insulation properties to prevent current leakage and short circuit.

[0074] The surface layer 224 may be provided with polyester fiber, nylon, etc. In addition, the surface layer 224 may also be coated with a layer of material having a far-infrared radiation function to better radiate heat into the passenger compartment, thereby improving the heating effect and user experience.

[0075] The graphene heating module 2 can be set in two ways. One is corresponding to the position of the door panel 11, as a part of the decorative part of the door panel 11, such as replacing the decorative panel near the original armrest of the door panel 11. Figure 5-7 Another corresponding to the central channel 13 and the glove box 12 position, can be set to Figure 8-10 The rectangle shown.

[0076] Embodiment 4:

[0077] Reference Figure 1 and Figure 8 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0078] The graphene heating module 2 further includes a heat exchange fan 23 , which is supported on the frame 21 to output the heat on the surface of the body 22 to the passenger compartment.

[0079] In this embodiment, the heat exchange fan 23 generates airflow to quickly transfer the heat generated on the surface of the graphene heating module 2 body 22 to the passenger compartment. This helps to speed up the heat conduction speed, and then cooperate with heat radiation to heat the passenger compartment more efficiently, while also making more full use of the heat of the graphene heating module 2, thereby further reducing energy consumption.

[0080] The airflow from the fan also helps create a more even temperature distribution within the passenger compartment. By constantly circulating the air, the fan reduces areas of overheating or overcooling, improving overall comfort.

[0081] The addition of the heat exchange fan 23 enables the heating module to not only provide heat, but also bring a more comfortable and natural feeling through the circulation of airflow, thereby helping to improve user experience and satisfaction.

[0082] The heat exchange fan 23 is supported on the frame 21, which ensures the stability and reliability of the fan. At the same time, it also makes the structure of the entire heating module more compact and reasonable, and is easy to install and maintain.

[0083] After adding the heat exchange fan 23, the performance of the graphene heating module 2 is significantly improved. It not only has the advantages of rapid heating and high efficiency and energy saving, but also improves temperature uniformity, heat utilization and user comfort through the circulation of airflow.

[0084] Specifically, the fan is driven by a low-power motor. Due to the low load, the energy consumption caused by the fan is almost negligible for the entire vehicle.

[0085] Embodiment 5:

[0086] Reference Figure 5-Figure 10 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0087] The graphene heating module 2 also includes an outer cover 24 fixedly connected to the frame 21; a first cavity and a second cavity separated by a partition are formed in the frame 21, and the main body 22 is arranged in the first cavity; an exhaust port B is opened on the side wall of the outer cover 24 corresponding to the first cavity, and an air inlet C is opened on the side wall of the outer cover 24 corresponding to the second cavity; a gas channel is opened on the partition, a fan can be supported on the partition, and when the fan is started, the air in the second cavity flows through the surface of the main body 22.

[0088] In this embodiment, the outer cover 24 is fixedly connected to the frame 21 to provide protection for the entire heating module and guide the air flow. The design of the outer cover 24 takes into account the position of the air inlet and outlet to ensure that the air can enter and discharge smoothly. The frame 21 is separated by a partition to form a first cavity and a second cavity. This design makes the air flow more orderly. The first cavity is used to accommodate the body 22 of the graphene heating module 2 and is the main area for heat generation. The second cavity is used as a channel for air to enter.

[0089] An air inlet C is provided on the side wall of the outer cover 24 corresponding to the second cavity, allowing external air to enter the second cavity. A gas channel is provided on the partition, and a fan can be supported in the gas channel. When the fan is started, the air in the second cavity flows under the action of negative pressure and flows to the first cavity through the channel, ensuring that the air can flow over the surface of the body 22 and take away heat. An exhaust port B is provided on the side wall of the outer cover 24 corresponding to the first cavity, allowing the air with heat to be discharged from the first cavity and enter the passenger compartment, thereby improving energy utilization.

[0090] That is, the fan forces convection, which speeds up the air flow over the surface of the body 22, thereby improving the heating efficiency. The design of the cover 24, the partition and the cavity makes the entire heating module compact and easy to install and maintain. The design of the cover 24 provides additional protection, preventing the user from directly contacting the heating element, thereby improving safety.

[0091] Specifically, a filter is provided at the air inlet C position to prevent dust from contaminating the body 22, and the air outlet is a through hole evenly distributed on the outer cover 24. At the same time, the portion of the outer cover 24 corresponding to the first cavity is provided with a transparent material, and the portion corresponding to the second cavity is provided with a non-transparent material. The transparent material can reduce the influence on the heat radiation, and the non-transparent material can shield the internal structures such as the fan and the motor to improve the aesthetics.

[0092] Embodiment 6:

[0093] Reference Figure 4 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0094] A socket is provided in the connection area A, and a plug is provided on the side of the frame 21 facing the interior decoration. When the graphene heating module 2 is installed in the connection area A, the corresponding plug and the corresponding socket are plugged into each other; the plug and the socket integrate an electrical connection structure, and the socket is connected to the vehicle power supply.

[0095] In this embodiment, when the graphene heating module 2 is installed in the connection area A, the corresponding sockets and sockets are plugged into each other to achieve a stable connection between the module and the interior decoration. The sockets and sockets not only achieve mechanical connection, but also integrate electrical connection structures. During the plugging process, the power supply can be automatically connected to the power supply end of the graphene heating module 2 without the need for additional wiring steps. This plug-in installation method greatly simplifies the installation process and improves installation efficiency. Users or maintenance personnel can easily complete the installation without professional electrical knowledge or tools.

[0096] The design of the integrated electrical connection structure avoids the potential safety hazards of traditional wiring methods, such as loose wiring, short circuit, etc. The plug-in connection method ensures a stable connection between the power supply and the heating module, and improves the reliability of the system. When the graphene heating module 2 needs to be repaired or replaced, it is only necessary to simply pull the module out of the socket without disassembling other components. This design reduces maintenance costs and improves maintenance efficiency.

[0097] Alternatively, the power supply module can be integrated on the frame 21, that is, an external power source independent of the power battery is used to power the graphene heating module 2, and the power supply module can be a small storage battery similar to a power bank.

[0098] Embodiment 7:

[0099] In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0100] The passenger compartment heating system based on graphene material also includes a heat-insulating layer arranged between the door panel 11 and the vehicle door. The heat-insulating layer includes heat-insulating cotton and a main body 22. The main body 22 is fixedly connected to the surface of the heat-insulating cotton facing the passenger compartment.

[0101] In this embodiment, the thermal insulation cotton is the main component of the thermal insulation layer and has excellent thermal insulation performance. It can effectively prevent heat from being transferred to external structures such as vehicle doors, thereby reducing heat loss and improving the efficiency of the heating system. The body 22 serves as a heating element, and the body 22 is fixedly connected to the surface of the thermal insulation cotton facing the passenger compartment. This design can ensure that the heat generated by the graphene layer 223 is directly transferred to the passenger compartment instead of being absorbed by structures such as vehicle doors.

[0102] When the heating system is started, the graphene layer 223 generates heat through electric current. Since graphene has extremely high thermal conductivity and electrothermal conversion efficiency, it can quickly and evenly generate a large amount of heat. The generated heat is first transferred to the thermal insulation cotton, but due to the thermal insulation performance of the thermal insulation cotton, most of the heat is reflected or retained in the thermal insulation layer, and then the heat is transferred to the passenger compartment through the surface of the thermal insulation cotton facing the passenger compartment.

[0103] The thermal insulation cotton acts as an insulating layer, effectively preventing the transfer of heat to external structures such as the doors, thereby maintaining a stable temperature in the passenger compartment. This not only improves heating efficiency, but also reduces energy consumption, because the system does not need to continuously generate a large amount of heat to offset heat loss, but the heat generated by the graphene layer 223 on the thermal insulation cotton allows the thermal insulation cotton to form a high-temperature thermal insulation barrier, thereby greatly improving the thermal insulation effect.

[0104] Embodiment 8:

[0105] In addition to providing a vehicle, an embodiment of the present invention includes a passenger compartment heating system based on graphene materials in any of the above embodiments. The vehicle includes an electric vehicle. Therefore, the vehicle includes all the beneficial effects of any of the above embodiments. To avoid repetition, they are not described here.

[0106] Embodiment 9:

[0107] Reference Fig.12 In addition to providing a vehicle passenger compartment heating method, the embodiment of the present invention is applied to the vehicle of the above embodiment, and the method includes:

[0108] S1: Detect the temperature T at the corresponding position of the passenger compartment and the power battery Soc;

[0109] S2: Based on T being less than a threshold value and Soc being greater than a threshold value, control the occupant recognition module 4 to recognize a passenger,

[0110] S3: based on the passenger identification module 4 identifying the passenger at the corresponding position, the graphene heating module 2 at the corresponding position is turned on.

[0111] This method is particularly suitable for vehicles equipped with a graphene heating module 2, and is intended to intelligently control the operation of the heating system according to the actual temperature of the passenger compartment and the charge state of the power battery, as well as the specific position of the passengers, so as to improve energy efficiency and passenger comfort.

[0112] The specific steps are as follows:

[0113] S1: Detect the passenger compartment temperature T and the power battery power Soc;

[0114] The temperature inside the passenger compartment is detected by the in-vehicle temperature sensor to obtain accurate ambient temperature data.

[0115] Check the remaining power of the power battery to ensure that there is enough power to start the heating system to avoid the vehicle being unable to operate normally due to power exhaustion.

[0116] S2: Based on T being less than a threshold value and Soc being greater than a threshold value, controlling the occupant recognition module 4 to recognize a passenger;

[0117] When the passenger compartment temperature T is lower than the set comfort temperature threshold, the system considers that heating needs to be started.

[0118] At the same time, the system checks whether the power battery Soc is greater than the minimum power threshold required to start heating to ensure that the battery will not be exhausted during the heating process.

[0119] When the above two conditions are met at the same time, the system controls the occupant identification module 4 to start working to identify the position of the passengers in the vehicle.

[0120] S3: based on the passenger identification module 4 identifying the passenger at the corresponding position, the graphene heating module 2 at the corresponding position is turned on;

[0121] The occupant identification module 4 identifies the specific position of the occupants in the vehicle through sensors.

[0122] According to the identified passenger position, the system only turns on the graphene heating module 2 at the corresponding position to achieve local heating. By intelligently controlling the opening and closing of the heating module, unnecessary energy waste is avoided and energy efficiency is improved. Local heating is provided according to the specific position of the passenger, so that the passenger can feel the warmth faster and improve comfort.

[0123] This method of heating the passenger compartment of a vehicle is particularly suitable for electric or hybrid vehicles that are equipped with a power battery as an energy source. In cold weather conditions, the system can flexibly and specifically heat the passenger compartment to provide a comfortable interior environment for passengers while protecting battery life and improving energy efficiency.

[0124] Specifically, the temperature detection module 5 can be configured to detect the temperature of each thermal field, so that the temperature control module 3 can independently control the graphene heating module 2 corresponding to each thermal field based on the temperature of each thermal field, thereby improving the heating flexibility.
