Description

Technical Field

[0001] This utility model relates to the field of electric vehicles, and in particular to a vehicle mobile energy charging device. Background Technology

[0002] Against the backdrop of a global push for sustainable development, the automotive industry is undergoing a profound transformation from traditional gasoline-powered vehicles to new energy-powered vehicles. With continuous breakthroughs in lithium-ion battery technology, motor control technology, and smart grid technology, environmentally friendly and energy-saving electric vehicles, with their significant advantages such as zero emissions, high energy efficiency, and low operating noise, are gradually becoming the dominant force in the future transportation sector.

[0003] However, the lagging development of charging infrastructure has become increasingly prominent in the rapid development of electric vehicles. Currently, most mainstream electric vehicles use centralized charging stations for charging, a model that relies on a widely covered charging network. However, the reality is that the number of charging stations is mismatched with the number of electric vehicles. This is especially true in third- and fourth-tier cities and rural areas, where the density of charging station deployment is insufficient, and some areas even have service blind spots. This leads to electric vehicle users frequently facing difficulties finding charging stations and long queues, requiring frequent route planning for long-distance travel, significantly impacting the convenience of vehicle use and range confidence. Furthermore, existing charging stations mostly use traditional AC slow charging technology, with a single charge taking 4-8 hours. Even with DC fast charging, it takes 30 minutes to 1 hour to replenish 80% of the battery, severely restricting vehicle efficiency and travel flexibility, becoming a key bottleneck hindering the large-scale popularization of electric vehicles.

[0004] Furthermore, the electric vehicle market offers a wide variety of battery types, including lithium-ion batteries, lithium iron phosphate batteries, and ternary lithium batteries, each with differences in voltage, charging curves, and safe operating range. The variety of battery types increases the R&D costs of charging infrastructure, requiring charging station manufacturers to invest more resources in technological development and equipment modifications to accommodate the charging needs of different battery types. At the same time, it's difficult to achieve a completely unified standard for charging infrastructure on the market. Users may encounter charging difficulties due to incompatibility between the charging equipment and their vehicle's battery, reducing the universality and ease of use of charging facilities. Utility Model Content

[0005] One objective of this invention is to overcome at least one deficiency in the prior art and provide a vehicle mobile energy charging device.

[0006] A further objective of this invention is to connect a charging power source installed in a car to the car to be charged via a charging connector, thereby charging the car. This eliminates the location limitations of fixed charging stations, allowing users to charge their vehicles in home garages, offices, or even temporary outdoor locations without having to travel to a charging station. This greatly improves the flexibility and convenience of charging and effectively alleviates the problem of "difficulty in finding charging stations."

[0007] Another further objective of this invention is to enable electric vehicles with different types of batteries to be charged by incorporating an energy management device within the charging connector and cooperating with a power consumption type detection device. This allows electric vehicles with different battery types from different manufacturers to be charged safely and efficiently on the same charging connector.

[0008] Specifically, this utility model provides a vehicle mobile energy charging device, comprising: a charging power supply, installed on a vehicle, for providing electrical energy to the vehicle and for charging a vehicle to be charged; a charging connector, disposed at the end of the line from the charging power supply to the vehicle to be charged, for modulating the electrical energy output by the charging power supply into electrical energy for charging the vehicle to be charged; and a charging detection module disposed within the charging connector, wherein when the charging connector is connected to the vehicle to be charged, the charging detection module is communicatively connected to the vehicle to be charged; so that when the charging power supply begins to discharge to the vehicle to be charged, the charging detection module sends a charging start signal to the vehicle to be charged.

[0009] Optionally, the charging connector includes: an input interface for connecting to a charging power source and for transmitting electrical energy output from the charging power source to the charging connector; and an output interface for connecting to the vehicle to be charged and for transmitting modulated electrical energy to the vehicle to be charged.

[0010] Optionally, the charging connector further includes: a power conversion device, the input end of which is connected to an input interface, and the output end of which is connected to an output interface, for modulating the power supplied by the charging power source.

[0011] Optionally, the charging connector may also include a power type detection module, connected to the output interface, for detecting the type of vehicle to be charged.

[0012] Optionally, the charging connector also includes an energy management device, which is connected to the power conversion device and the power consumption type detection module respectively, for selecting an appropriate output voltage according to the type of vehicle to be charged detected by the power consumption type detection module.

[0013] Optionally, the power conversion device includes: a winding for increasing or decreasing the input AC voltage to a desired voltage value; and a magnetic core made of nanocrystalline material to enhance electromagnetic induction.

[0014] Optionally, the power conversion device further includes: a first modulation module for modulating the DC power output from the charging power supply into AC power and supplying it to the winding; and a second modulation module for modulating the AC power output from the winding into DC power and supplying it to the vehicle to be charged.

[0015] Optionally, the vehicle to be charged includes: a first type of vehicle to be charged, wherein a lithium battery is installed in the first type of vehicle to be charged and the voltage of the first type of vehicle to be charged is 400V; and a second type of vehicle to be charged, wherein a solid-state battery is installed in the second type of vehicle to be charged and the voltage of the second type of vehicle to be charged is 1000V.

[0016] Optionally, the charging power supply is a solid-state battery, and the output voltage of the charging power supply is 1000V.

[0017] Optionally, the charging connector further includes an anomaly detection module, which is connected to the charging power supply and the vehicle to be charged respectively during the charging process of the vehicle to be charged, and is used to disconnect the charging connector from the vehicle to be charged in the event of a charging anomaly.

[0018] The vehicle-mounted mobile energy charging device provided by this utility model can charge other vehicles via a charging connector within a charging power supply installed in a car. The charging power supply, installed in the car, can both power its own vehicle and provide energy to other vehicles. This design achieves the sharing of charging resources; a vehicle's charging power supply can meet its own needs while also providing services to other vehicles, alleviating the pressure of insufficient charging infrastructure to a certain extent and improving the utilization rate of charging resources throughout society.

[0019] Furthermore, the charging connector is equipped with a power conversion device and a power consumption type detection module. These two devices work together to enable the charging power supply to charge different types of vehicles. Different types of vehicles may have different charging interface, voltage, current, and other parameter requirements. The power consumption type detection module automatically identifies the power consumption type of the vehicle being charged, while the power conversion device converts the electrical energy from the charging power supply into an electrical energy form that meets the requirements of the vehicle being charged, ensuring smooth charging. This solves the problem of inconsistent charging interfaces and electrical parameters for different brands and models of vehicles, greatly improving the versatility and applicability of the charging device.

[0020] The above and other objects, advantages and features of this utility model will become more apparent to those skilled in the art from the following detailed description of specific embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

[0021] The following sections will describe some specific embodiments of the present invention in a detailed manner by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or components. Those skilled in the art should understand that these drawings are not necessarily drawn to scale. In the drawings:

[0023] Figure 2 This is a connection diagram of a charging connector according to an embodiment of the present invention;

[0024] Figure 3 This is a circuit connection diagram of an energy conversion device according to an embodiment of the present invention. Detailed Implementation

[0025] This utility model provides a mobile energy charging device for vehicles. Figure 1 This is a connection diagram of a vehicle-mounted mobile energy charging device according to an embodiment of the present invention. The vehicle-mounted mobile energy charging device of this embodiment generally includes a charging power supply 100 and a charging connector 200. The charging power supply 100 is installed in the vehicle, not only meeting the vehicle's own power needs but also providing energy for charging a vehicle 300 to be charged. The charging power supply 100 and the vehicle 300 to be charged are connected via the charging connector 200 to enable the charging power supply 100 to supply power to the vehicle 300. The charging connector 200 is located at the end of the charging line from the charging power supply 100 to the vehicle 300. The electrical energy output from the charging power supply 100 is modulated by the charging connector 200 to output charging energy matching that of the vehicle 300 to be charged, thereby achieving charging of the vehicle 300. This method enables energy sharing between vehicles and improves energy utilization efficiency. For example, when one car has a full charge while another has a low charge, the car with the full charge can provide its excess power to the car with the low charge. This energy-sharing function is especially important in certain scenarios, such as remote areas or areas with few charging stations.

[0026] Furthermore, a charging detection module 210 is provided inside the charging connector 200. When the charging connector 200 is connected to the vehicle 300 to be charged, the charging detection module 210 inside the charging connector 200 establishes a communication connection with the vehicle 300. After the charging connector 200 is connected to the vehicle 300, the charging power supply 100 begins to discharge to the vehicle 300. At this time, the charging detection module 210 should send a charging start signal to the vehicle 300. After receiving the charging start signal, the vehicle 300 should enter charging mode. In charging mode, the air conditioning, audio system, and other equipment in the vehicle can be used, but the vehicle's power system must be disabled. This increases the convenience and comfort of the user during charging and avoids accidental vehicle movement due to misoperation or other reasons during charging. This prevents damage to the charging equipment or safety accidents caused by pulling on the charging cable due to vehicle movement during charging, ensuring the safety and stability of the charging process.

[0027] In some alternative embodiments, the charging connector 200 includes an input interface 201 and an output interface 202. Figure 2 This is a connection diagram of a charging connector 200 according to an embodiment of the present invention. The input interface 201 is connected to the charging power supply 100 and is used to deliver electrical energy output from the charging power supply 100 to the charging connector 200. The charging connector 200 internally modulates the electrical energy into power usable for charging the vehicle 300. The modulated electrical energy is then delivered to the vehicle 300 via the output interface 202. The design of the input interface 201 and the output interface 202 provides a stable power source for the charging connector 200, ensuring the continuity of power supply during charging, thereby reducing interruptions or fluctuations in power transmission caused by poor contact and other problems, and ensuring charging stability.

[0028] In some optional embodiments, the charging connector 200 further includes a power conversion device 220. The input and output terminals of the power conversion device 220 are connected to the input interface 201 and the output interface 202, respectively. During the charging process of the charging power supply 100 to the vehicle 300, the power conversion device 220 is mainly responsible for modulating the electrical energy output by the charging power supply 100 into electrical energy usable for charging the vehicle. For example, the charging power supply 100 outputs 1000V DC, while the charging voltage of the vehicle 300 is 400V. In this case, the power conversion device 220 needs to step down the voltage of the electrical energy output by the charging power supply 100 so that the voltage output by the power conversion device 220 can meet the charging requirements of the vehicle 300. Due to the presence of the power conversion device 220, power transfer between the charging power supply 100 and the vehicle 300, despite their different voltage levels, can be ensured, thus solving the problem of voltage mismatch between the charging power supply 100 and the vehicle 300 and expanding the applicability of the charging device.

[0029] In some optional embodiments, the charging connector 200 further includes a power type detection module 230. The power type detection module 230 is connected to the output interface 202. When the charging connector 200 is connected to the vehicle 300 to be charged, the power type detection module 230 can connect and communicate with the vehicle 300, and identify the type of the vehicle 300 and obtain its charging parameter information based on the communication content. By identifying different vehicle types and charging parameters, the power type detection module 230 allows the charging connector 200 to adapt to various brands and models of vehicles 300, greatly improving its compatibility and versatility. Regardless of the different charging interface specifications or electrical parameters of the vehicles, the charging connector 200 can match them, reducing the inconvenience for users who need to replace charging equipment due to different vehicle types.

[0030] In some optional embodiments, the charging connector 200 also includes an energy management device 240. The energy management device 240 is communicatively connected to the power conversion device 220 and the power consumption type detection module 230. During the charging process of the charging power supply 100 to the vehicle 300, the power consumption type detection module 230 detects the type of the vehicle 300 and sends the detected vehicle type data to the energy management device 240. The energy management device 240 determines the charging parameters based on the received vehicle type and sends these charging parameters to the power conversion device 220 so that the voltage output by the power conversion device 220 can meet the charging requirements of the vehicle 300. For example, when a vehicle 300 is connected to the charging connector 200, the power consumption type detection module 230 quickly establishes communication with the vehicle, identifies its vehicle type, and obtains parameter information such as the vehicle's battery charging voltage needing to be stable at 400V and the maximum charging current at 120A. This data is then transmitted to the energy management device 240. The energy management device 240, based on the current state of charge and health of the vehicle's battery, uses a built-in algorithm to determine that 400V voltage and 120A current are the charging parameters for this operation, and sends the instruction to the power conversion device 220. At this time, the charging power supply 100 outputs 1000V DC power. Upon receiving the instruction, the power conversion device 220 immediately starts the conversion program, performing voltage reduction and current regulation on the input power, ultimately outputting 400V, 120A DC power that meets the requirements of the electric vehicle 300 to be charged. This power is then safely and efficiently charged through the output interface 202. The entire process requires no manual intervention, achieving intelligent and precise charging adaptation. The specific voltage and current parameters described above are merely examples; those skilled in the art can adjust the output parameters of the power conversion device 220 based on the specific parameters of the electric vehicle battery.

[0031] In some alternative embodiments, the power conversion device 220 includes a winding 221 and a magnetic core 222. Figure 3This is a circuit connection diagram of a power conversion device 220 according to an embodiment of the present invention. The winding 221 is used to increase or decrease the input AC voltage to the required voltage value; the magnetic core 222 is used to enhance the electromagnetic induction effect. The magnetic core 222 can be made of nanocrystalline material or amorphous material. For example, the on-board battery of a certain car 300 to be charged requires 400V DC charging, while the charging power supply 100 outputs 1000V DC. After the charging connector 200 is connected, the power conversion device 220 starts to work: the winding 221 in the power conversion device 220, based on the principle of electromagnetic induction and through a reasonable turns ratio design, reduces the input 1000V AC voltage; simultaneously, the magnetic core 222, made of nanocrystalline material, plays its role. With its high permeability and low loss characteristics, it greatly enhances the electromagnetic induction effect between the windings 221, enabling efficient power transfer and stabilizing the voltage to the required voltage for charging an electric truck. After rectification and other subsequent processing, a stable 400V DC power is finally output, providing safe and efficient charging for the 300 vehicles waiting to be charged.

[0032] Furthermore, amorphous materials can be amorphous silicon. Amorphous silicon not only possesses excellent mechanical properties but also outstanding magnetic properties. Its thin strips exhibit high plasticity when bent, allowing for repeated bending without breakage, making it advantageous in structural components that require resistance to deformation. Moreover, it has high tensile strength; for example, many amorphous alloys achieve high tensile strengths, far exceeding those of some common crystalline metals, making it suitable for applications requiring high material strength.

[0033] Furthermore, the disordered atomic arrangement of amorphous silicon means that amorphous materials do not have the anisotropy of crystals and have higher magnetic permeability. This means that under the influence of a magnetic field, amorphous materials are more easily magnetized and can conduct magnetic field lines more efficiently, resulting in less eddy current loss generated by amorphous silicon in an alternating magnetic field.

[0034] Furthermore, amorphous silicon can be prepared by relatively simple methods such as rapid cooling. For example, molten metal can be sprayed onto a high-speed rotating cooling roller to quickly obtain amorphous metal strips. The process is relatively simple, energy-saving, pollution-free, and beneficial to environmental protection.

[0035] In some optional embodiments, the power conversion device 220 further includes a first modulation module 223 and a second modulation module 224. The first modulation module 223 modulates the DC power output from the charging power supply 100 into AC power and sends it to the winding 221 for voltage boosting or bucking. After voltage boosting or bucking, the current is modulated into DC power by the second modulation module 224 and sent to the vehicle 300 to be charged for charging.

[0036] Furthermore, the primary function of the first modulation module 223 is to convert direct current (DC) to alternating current (AC), typically achieved using inverter technology. Its core components are power switching devices, such as insulated-gate bipolar transistors (IGBTs) or metal-oxide-semiconductor field-effect transistors (MOSFETs). Under the control of the circuit, these switching devices alternately turn on and off according to a certain pattern, thus "cutting" the DC into a series of pulse signals. By rationally designing the control circuit and switching frequency, these pulse signals can simulate an approximately sinusoidal AC wave. For example, in a simple single-phase inverter, by controlling the on / off state of two switching transistors, the output voltage alternates between positive and negative levels within one cycle. After filtering and other processing, a relatively smooth AC current can be obtained. In this way, the DC output from the charging power supply 100 is modulated into AC suitable for boosting or bucking the winding 221.

[0037] Furthermore, the second modulation module 224 converts the AC power boosted or stepped down by winding 221 into DC power suitable for the vehicle 300 to be charged. This process is mainly achieved through rectification and filtering. The rectification section typically uses a diode bridge rectifier circuit, which utilizes the unidirectional conductivity of diodes to convert both the positive and negative half-cycles of the AC power into DC power in the same direction, i.e., turning the AC signal into a pulsating DC signal. However, this pulsating DC signal still has significant ripple and cannot be directly used to charge the vehicle, so a filtering circuit is needed to smooth the voltage. The filtering circuit generally consists of components such as capacitors and inductors. Capacitors can store charge, charging when the voltage rises and discharging when the voltage drops, thereby reducing voltage fluctuations; inductors smooth the current by impeding changes in current. After rectification and filtering, the AC power is converted into stable DC power, which can meet the charging needs of the vehicle 300 to be charged.

[0038] It should be noted that "first modulation module 223" and "second modulation module 224" should be understood as follows: the modulation module connected to the charging power supply 100 is the first modulation module 223, and the modulation module connected to the vehicle 300 to be charged is the second modulation module 224. Alternatively, the first modulation module 223 and the second modulation module 224 can be distinguished based on their function: the first modulation module 223 modulates DC to AC, and the second modulation module 224 modulates AC to DC. For example... Figure 2 As shown, the first modulation module 223 is connected to the input interface 201, and the second modulation module 224 is connected to the output interface 202.

[0039] In some alternative embodiments, the power conversion device 220 can be a novel power conversion device 220 based on high-frequency power electronic conversion technology, such as a power electronic transformer (PET). The PET achieves voltage conversion, electrical isolation, and power quality control functions through semiconductor switching devices and a high-frequency transformer core 222. Essentially, it combines the electromagnetic induction principle of traditional transformers with power electronic technology to support bidirectional energy transmission and intelligent management in AC / DC hybrid networks.

[0040] In some optional embodiments, the vehicle to be charged 300 includes a first type of vehicle to be charged 300 and a second type of vehicle to be charged 300. The first type of vehicle to be charged 300 may contain a lithium battery, and the second type of vehicle to be charged 300 may contain a solid-state battery. The lithium battery uses a voltage of 400V, and the solid-state battery uses a voltage of 1000V. Alternatively, the first type of vehicle to be charged 300 may contain a solid-state battery, or the second type of vehicle to be charged 300 may contain a lithium battery. The lithium battery voltage may also be set to 1000V, or the solid-state battery voltage may be set to 400V. The above examples of battery types and specific voltages in the vehicle to be charged 300 are specific examples; those skilled in the art can adjust the battery type and voltage based on the specific parameters of the electric vehicle battery.

[0041] In some optional embodiments, the charging power supply 100 is a solid-state battery, and the output voltage of the charging power supply 100 is 1000V. That is, the 1000V charging power supply 100 can charge both lithium-ion battery vehicles 300 with a voltage of 400V and solid-state battery vehicles 300 with a voltage of 1000V. Using a solid-state battery with an output voltage of 1000V as the charging power supply 100 can simultaneously charge both lithium-ion battery vehicles 300 with a voltage of 400V and solid-state battery vehicles 300 with a voltage of 1000V. The application of this mobile energy charging device means that one charging power supply 100 can be adapted to multiple types of vehicles 300, improving the versatility and applicability of the charging power supply 100, reducing the deployment and investment of different types of charging power supplies 100, and reducing the construction cost and complexity of charging infrastructure.

[0042] In some optional embodiments, the charging connector 200 further includes an anomaly detection module 250, which is connected to both the charging power supply 100 and the vehicle 300 during the charging process. If an anomaly occurs during charging, the connection between the charging connector 200 and the vehicle 300 is disconnected. The anomaly detection module 250 can monitor various parameters during charging, promptly detect and handle anomalies, ensure stable charging, and reduce the probability of charging interruptions and malfunctions. For example, if voltage fluctuations in the charging power supply 100 cause unstable output, the anomaly detection module 250 can adjust or interrupt charging in a timely manner, resuming charging only after the voltage stabilizes, thus ensuring charging quality.

[0043] In some optional embodiments, the vehicle-mounted mobile energy charging device may further include an on-board station control module for monitoring key indicators during the charging process, such as battery capacity and load power metering. It may also monitor the status of core equipment, such as the operating status of the battery and charging connector 200.
