Recently, Huawei, which “does not build cars,” has published two more important patents, namely, a patent for a method for charging between electric vehicles and electric vehicles, and an invention patent for a method for secure communication in the Internet of Vehicles. For the current automotive market, these two patents symbolize the development trend of “electricity and connectivity” among the new four modernizations.
According to the patent abstract of Huawei Technologies Co., Ltd. “Electric Vehicles and Methods for Charging Between Electric Vehicles”, the embodiments of the present invention provide a method for charging between electric vehicles and electric vehicles. The electric vehicle includes: a battery pack; a DC socket; a controller. During the process of connecting the DC socket and the AC socket of another electric car through a charging and discharging cable, the battery pack is controlled to be another electric car according to the charging request of another electric car Charging can realize the charging between electric vehicles more conveniently. At present, mutual charging and discharging between two electric vehicles is still relatively rare in the industry.
Another patent abstract of “A Method for Secure Communication in the Internet of Vehicles” shows that this application proposes a security agency solution to coordinate or assist the Internet of Vehicles terminal and the field-side server for secure communication. The security agent is assumed by a trusted node or entity located in the security domain or the IoV terminal. The IoV terminal establishes a secure connection with the security agent and negotiates the security context that can be used for the secure session, and then the security agent forwards the security context to the field. End server. In this way, the terminal and the farm-side server can use the security context for secure communication. By introducing a security agent and migrating the security context to the field server through the security agent, it not only realizes the secure communication between the car networking terminal and the field server, but also avoids configuring or saving the car networking necessary for negotiating the security context on the field server Security information of the terminal.
It is worth mentioning that according to data released by the World Intellectual Property Organization, in the three years from 2017 to 2019, Huawei from China has continuously ranked first in the number of PCT patent applications by enterprises worldwide. According to data released by the State Intellectual Property Office of China, in 2019, China submitted 58,900 patent applications through the World Intellectual Property Organization's Patent Cooperation Treaty (PCT), surpassing 57,800 patent applications in the United States and rising to the world's first place. , Becoming the country with the largest number of international patent applications.
In addition to the above-mentioned patents related to electric vehicle charging and car networking safety communication, we found that Huawei has published a number of electric vehicle related patents since 2021, including “a brake assist system and braking method, electric vehicle” , “Pedestrian detection methods, devices, computer-readable storage media and chips”, “Silicon-carbon composite materials and preparation methods and lithium-ion batteries” that can extend battery life, and “New energy vehicle reducers, powertrains and vehicles” And other related patents. Although Huawei has always stated that it “will not build cars,” the content of the patents all point to important or innovative links in new energy vehicles and intelligent networked vehicles. In the future, Huawei will surely become one of the powerful suppliers in the automotive industry.(More in autofun: harga sigra)
