Vehicle charging port and vehicle charging device including the same

[0001] The present invention relates to a vehicle charging port and a vehicle charging device including the same.

[0002] Eco-friendly vehicles such as electric vehicles (EVs) or plug-in hybrid electric vehicles (PHEVs) use electric vehicle supply equipment (EVSE) installed at charging stations to charge their batteries.

[0003] Several standards are actively being developed to facilitate interaction between electric vehicles and EVSE. These standards for electric vehicle charging can be broadly categorized into charging systems, charging interfaces, and communication protocols.

[0004] However, since different regulations are adopted by each country or automobile company, the charging devices, battery packs, and battery management systems (BMS) of electric vehicles must be developed and designed according to the regulations.

[0005] To enhance the convenience of drivers of eco-friendly vehicles such as electric vehicles, various technologies are needed to shorten electric charging times and improve the environment of charging stations, including electric vehicle chargers.

[0006] The vehicle charging port generates heat during charging. Effective heat control is essential to prevent performance degradation, shortened component lifespan, and fire hazards due to overheating. Existing heat dissipation methods include passive methods utilizing fans and heat sinks, and active methods utilizing coolant. Passive methods are inexpensive and easy to maintain, but suffer from low efficiency. Active methods offer high cooling efficiency, but suffer from complex structures and high maintenance costs.

[0021] The other surface of the housing includes a plate, an electromagnetic shielding plate disposed on the plate, and a heating plate disposed on the electromagnetic shielding plate, and the plurality of protrusions of the housing can be formed on the heating plate.

[0022]

[0023] In order to solve the above technical problem, a vehicle charging port according to an embodiment of the present invention includes a housing; a charging socket disposed in the housing; and a door connected to the housing, wherein one side of the housing faces the door, the other side of the housing faces the interior of the vehicle, and the other side of the housing includes a plate, a first pattern layer disposed on the plate to form a first region, and a second pattern layer disposed on the first pattern layer to form a second region.

[0024] The other surface of the housing may include a first structure including a plurality of first holes spaced apart from each other and a second structure including a plurality of second holes spaced apart from each other, and the first region and the second region may be formed to connect the first holes and the second holes.

[0028] According to the present embodiments, charging efficiency can be increased through a vehicle charging inlet and charging gun combination structure that enables simultaneous wired and wireless charging.

[0029] Additionally, the use of shielding can improve wireless charging efficiency by reducing leakage flux and prevent EMF (Electromagnetic field) that may occur during charging.

[0030] In addition, the coupling coefficient can be increased by increasing the area where the transmitting coil and receiving coil face each other, thereby improving wireless charging efficiency.

[0031] Additionally, the heat generated at the contact points of the charging gun and charging socket during charging can be actively dissipated to maximize charging efficiency.

[0032] Additionally, the vehicle components can be protected from EMF generated from the charging socket through a structure in which ferrite is wrapped around the heat dissipation structure of the charging socket.

[0033] Additionally, the heat dissipation structure is maintained through PVC material, and the material that mixes metal and graphite materials allows the maximum surface area to be exposed to the air, and by making contact with the car body, heat dissipation can be achieved over the maximum surface area.

[0034] In addition, by applying a structure that allows air to circulate at the rear of the vehicle charging port, the heat generated at the contact points of the charging gun and charging socket during charging can be actively dissipated, thereby maximizing charging efficiency.

[0082]

[0083] The Electric Vehicle Communication Controller (EVCC, 130) can perform charging signal and charging power control within the vehicle. The EVCC (130) can be connected to an Electronic Control Unit (ECU) within the vehicle (10). The EVCC (130) can communicate with the battery management unit of the vehicle (10). The EVCC (130) can be connected to the battery management unit via wired or wireless connections.

[0084] The Battery Management System (BMS) can monitor the temperature of the vehicle battery. The BMS monitors the voltage, current, and temperature of the vehicle battery to maintain it in optimal condition. The BMS can transmit vehicle battery charge information, vehicle charging speed, and vehicle battery information to the EVCC (130). The BMS can also transmit the vehicle battery temperature to the EVCC (130).

[0085] The EVCC (Electric Vehicle Communication Controller, 130) can control the first wired charging unit (110) and the first wireless charging unit (120) according to the charging method. The EVCC (130) can communicate with the control unit of the EVSE (200). A control signal generated by the EVCC (130) according to the charging method can be transmitted to the control unit of the EVSE (200). The control unit of the EVSE (200) can control the second wired charging unit (220) and the second wireless charging unit (230) according to the charging method.

[0086] The EVCC (130) can control the charging method in one of the following: a first charging mode in which the battery is charged with the first wired charging unit (110), a second charging mode in which the battery is charged with the first wireless charging unit (120), and a third charging mode in which the battery is charged with the first wired charging unit (110) and the first wireless charging unit (120).

[0087] The EVCC (130) can control the charging method in a first charging mode in which the battery is charged with the first wired charging unit (110) when wireless charging is not possible. The EVCC (130) can control the charging method in a second charging mode in which the battery is charged with the first wireless charging unit (120) when wired charging is not possible. The EVCC (130) can charge the vehicle battery and the starting battery in the second charging mode. The EVCC (130) can perform emergency charging of the discharged starting battery in the second charging mode. The EVCC (130) can perform V2V (Vehicle to Vehicle) charging in the second charging mode in a situation in which the vehicle cannot go to a charging station. The EVCC (130) can control the charging method in a third charging mode in which the battery is charged with the first wired charging unit (110) and the first wireless charging unit (120) when fast charging is required.

[0088] The EVCC (130) can control the charging method to one of the first charging mode to the third charging mode depending on the amount of heat generated by the first wired charging unit (110) and the first wireless charging unit (120). When the temperature between the inlet (21) and the charging gun (210) exceeds a first value, the EVCC (130) can be controlled to the first charging mode or the second charging mode. Here, the first charging mode or the second charging mode can be set by the user's selection and can be selected by the charging environment. When the temperature between the inlet (21) and the charging gun (210) is lower than the first value, the EVCC (130) can be controlled to the third charging mode. According to another embodiment, the EVCC (130) can control the charging method based on the temperature of the battery rather than the temperature between the inlet (21) and the charging gun (210).

[0089] The EVCC (130) can control the charging method to one of the first charging mode to the third charging mode depending on the charging speed of the first wired charging unit (110) and the first wireless charging unit (120). For example, in a charging environment where both wired charging and wireless charging are possible, if the wired charging speed is fast, charging can be controlled to the first charging mode, and if the wireless charging speed is fast, charging can be controlled to the second charging mode.

[0090] The EVCC (130) can control the charging ratio of the first wired charging unit (110) and the first wireless charging unit (120) according to the heat generation and charging speed of the first wired charging unit (110) and the first wireless charging unit (120) in the third charging mode. For example, in the third charging mode, when the heat generation of the first wired charging unit (110) is greater than the heat generation of the first wireless charging unit (120), the EVCC (130) can control the charging ratio of the first wired charging unit (110) to be greater than the charging ratio of the first wireless charging unit (120). In the third charging mode, when the charging speed of the first wired charging unit (110) is greater than the charging speed of the first wireless charging unit (120), the EVCC (130) can control the charging ratio of the first wired charging unit (110) to be greater than the charging ratio of the first wireless charging unit (120).

[0091] In the third charging mode, when the temperature between the inlet (21) and the charging gun (210) exceeds the second value, the EVCC (130) can control the charging ratio of the first wired charging unit (110) to be greater than the charging ratio of the first wireless charging unit (120). In the third charging mode, when the temperature between the inlet (21) and the charging gun (210) is less than the second value, the EVCC (130) can control the charging ratio of the first wired charging unit (110) to be lower than the charging ratio of the first wireless charging unit (120).

[0092] The EVCC (130) can control the charging ratios of the first wired charging unit (110) and the first wireless charging unit (120) according to the heat generation amount of the battery in the third charging mode. When the temperature of the battery exceeds the third value in the third charging mode, the EVCC (130) can control the charging ratio of the first wired charging unit (110) to be greater than the charging ratio of the first wireless charging unit (120). When the temperature of the battery is lower than the third value in the third charging mode, the EVCC (130) can control the charging ratio of the first wired charging unit (110) to be lower than the charging ratio of the first wireless charging unit (120).

[0093] Fig. 12 is an exemplary flowchart illustrating the operation of selecting a charging method among the first to third charging modes by the EVCC (130). Charging is initiated by selecting a charging method according to a charging environment that allows wired charging, wireless charging, or both wired and wireless charging. If the battery temperature is below 90°C while wired charging is in progress, vehicle battery charging continues, and if the battery temperature exceeds 90°C, vehicle battery charging may be terminated.

[0094] If the battery temperature exceeds 40°C while wireless charging is in progress, the vehicle battery can be charged, and in an emergency, the starting battery can be charged. If the battery temperature is below 40°C, the charging method can be controlled to allow both wired and wireless charging. If the battery temperature exceeds 90°C while wired and wireless charging are in progress, the charging method is controlled to wireless charging. If the battery temperature is below 90°C, the vehicle battery can be charged, and in an emergency, the starting battery can be charged. These are examples only, and the charging method may vary depending on the charging environment and battery temperature.
