The charging gun electronic lock tears the gap changes from quantity to quality of  the charging pile market

In the past year of 5G licensing, under the wave of "new infrastructure", 5G construction has accelerated, 5G applications are blooming everywhere, and terminal applications are beginning to emerge. On May 9, 18 automakers joined hands with Huawei to build an automotive ecosystem, to accelerate the commercialization of 5G technology in the automotive industry.

In this year's government work report, representatives of the National People's Congress discussed increasing the coverage of charging piles. With the continuous support of policies and the rebound in sales of new energy vehicles, new energy vehicles will usher in new development opportunities in the future. However, charging facilities are still the main shortcoming of the new energy vehicle industry chain. Insufficient total number of charging piles, uneven distribution, incomplete interconnection and other practical problems, resulting in insufficient charging convenience, affecting the charging experience and sense of acquisition of new energy vehicle users, and also restricting the rapid health of the new energy vehicle industry to a certain extent development of.

Charging facilities are connected to the car, the construction of the city and the power grid. At present, the utilization rate of charging piles with “wide spreading network” and “low interoperability” is low. The big problem is the unreasonable planning and layout, and the construction of charging facilities must be combined with the construction of smart cities. But the deepest problem is that the voltage of current charging piles is generally higher than that of household electricity in our country, which greatly increases the risk of electric shock for consumers. Therefore, anti-electric shock measures equipped with charging piles are essential. The hidden safety hazards of charging guns are also most easily overlooked.

This is mainly because the voltage of charging piles is relatively high, some even reach about 750 volts, which is several times higher than the voltage of ordinary household electricity. Even if the user does not directly touch the charged contacts of the charging gun, too close a contact distance may cause a fatal risk of electric shock. According to requirements, in order to prevent the user from pulling the gun and getting an electric shock while charging, the charging pile needs to be equipped with an electronic lock inside to monitor the charging status.

Making charging piles easy to use, safe and durable is a problem that many new energy vehicle charging pile equipment manufacturers need to solve urgently. Shenzhen Zhaowei Electromechanical Co., Ltd. (hereinafter referred to as "Zhaowei") is adopting micro-drive technology to optimize the structure of the lock gear box of the electronic lock of the charging pile charging gun. Through the analysis and design of the charging pile gearbox scheme, Zhaowei adjusts the gear modulus and torque of the charging pile locking gearbox to improve the overall movement accuracy, reliability, and environmental adaptability of the charging pile, and increase its service life;the reduction gear box and the screw rod are used to stably maintain the charging plug in the buckle position of the socket or the fixing seat when the charging pile is moving forward, so as to achieve the anti-dropping lock function. After charging (when moving in reverse), it is separated from the buckle of the socket or fixed seat to achieve the unlocking function, which can realize the charging of electric vehicles without supervision.

With the maturity of new energy vehicles and charging pile technologies, the division of labor in the charging pile industry chain is becoming more and more clear. The more critical parts of the charging pile are the charging module, main control and cabinet. New energy vehicles are not simply "oil-to-electricity", but are developing in the direction of smart mobile terminals. As an important support for the development of the new energy vehicle industry, charging piles need to be digitalized and intelligently upgraded accordingly. The Zhaowei charging pile gearbox solution continuously innovates in structure and space design to improve reliability and reduce total cost. The charging pile locking gearbox also has the characteristics of large torque rigidity, low vibration, strong impact resistance, large carrying capacity, large starting power, and transmission efficiency, which can better meet the transmission needs of smart cars.

According to statistics from the China Charging Alliance, among the top 24 large-scale operators nationwide (with 1,000 charging piles and above) in April 2020, auto companies NIO and BYD are both on the list. SAIC Anyue, as a subsidiary of SAIC Group engaged in the investment, construction and operation of new energy vehicle charging facilities, ranked sixth with 18,841 units.

According to forecasts, the charging pile industry under the "new infrastructure" is expected to generate a trillion-yuan market. Last year, the Ministry of Industry and Information Technology released the "New Energy Vehicle Industry Development Plan (2021-2035)" for comments, and proposed that by 2025, the sales of new energy vehicles will account for 25% of the sales of new vehicles. It is estimated that by 2030, the number of new energy vehicles in China will reach 64.2 million. According to the construction goal of 1:1 vehicle to pile ratio, in the next ten years, there will be a gap of 63 million in the construction of charging piles in China, which is expected to form 1.02 trillion. Yuan’s charging pile infrastructure construction market.

Existing statistics show that by 2030, the number of new energy vehicles in my country will exceed 60 million. According to the 1:1 construction goal of vehicle piles, the construction scale of charging piles in the future will also exceed 60 million, especially driven by the new infrastructure market, which may give birth to a trillion-level charging pile infrastructure market. The trillion-dollar market blueprint allows the first-tier players such as State Grid to speed up, while small and medium-sized enterprises in various regions will use policy push to quickly seize the dominant position, which will form a situation where large and small companies compete.

With the increase in new energy and new infrastructure policies, more and more companies are engaged in charging guns, but each product still lacks unified standards such as the selection of charging pile materials, port design, and cable requirements. Clearly defined. Secondly, the inspection standards need to be improved. Once these products cannot withstand harsh environments such as high temperature and low temperature, they will inevitably bury hidden dangers for charging safety. A tiny screw, a small structure, and even an inconspicuous parameter will directly affect the development of an industry. Therefore, no matter how insignificant equipment is, it will affect the whole body of related industries. For example, when the charging gun of the charging pile is connected with the car charging interface, the metal sheet is not in close contact, which may cause a short circuit and cause a safety accident. Shenzhen Zhaowei Electromechanical Co., Ltd. was established in 2001 and is a company that designs, develops, and produces precision transmission system manufacturing companies can help charging pile equipment companies improve product quality and safety in micro-transmission and precision injection molding, and contribute to the country's new infrastructure construction.

Solving the problem of "quantity" of charging piles is only the first step for the industry to improve the charging experience of consumers. Zhaowei solves the problem of electricity safety in the details of the electronic lock of the charging pile charging gun. With the rapid growth of electric vehicles and the layout of Huawei's automotive ecosystem, the construction of charging piles has become an essential part of the development process. At present, the national level has listed new energy vehicle charging piles as one of the seven major areas of "new infrastructure". In order to help consumers reduce "mileage anxiety", the current improvement of the efficiency and coverage of charging/replacement facilities is a solution to the support of new energy vehicle infrastructure. The solution to the problem. "New infrastructure" is no longer a scale expansion in the traditional sense, but is closely connected with high and new technology. It is an important carrier for the development of informatization, intelligence, and digitization. This will help the charging pile industry complete the transformation from quantity to quality.
