With changes in the domestic and foreign trade situation, our country's economy is gradually shifting to high-quality development. As a node of the global comprehensive transportation network, ports play an increasingly important role in the development of modern logistics. Port development is gradually transforming to high-quality development, and "integration, intelligence, and green" have become the new direction of port transformation. The country and society are paying more and more attention to green development. Vehicles used in ports, such as heavy trucks, loaders, and tractors, are also developing new energy sources. "Zero-emission" pure electric operating vehicles will become the main tool for port transportation.

At present, port terminal loaders have entered a replacement cycle. According to statistics, the amount of old equipment with National II standards and below accounts for more than one-third of the equipment inventory. In the medium to long term, accelerating the elimination of high-emission non-road mobile machinery will significantly drive market demand for equipment renewal.

Fuel loaders consume large amounts of fuel and emit high carbon dioxide emissions, making them a key product for new energy. In terms of usage costs, assuming that it operates for 10 hours a day and 300 days a year, the fuel loader consumes 20L of fuel per hour, and the annual operating cost is about 522,000 yuan. At the same time, in terms of maintenance and repair, assuming that the annual cost of a fuel loader is 30,400 yuan, we estimate that within a five-year period, the operating cost of a fuel loader will be more than 2.762 million yuan.

On January 21, 2022, the Ministry of Transport issued the "Green Transportation "14th Five-Year Plan" Development Plan" to strengthen the requirements for green development of ports. In view of the fact that diesel trucks at container ports mainly use diesel, which is the main source of direct carbon emissions at container ports, it is proposed Promote the priority use of new and clean energy in the new and replacement of port operation machinery, port vehicles and tugboats, and freight station operation vehicles. Requires 11 ports including Shanghai Port, Dalian Port, Tianjin Port, Qingdao Port, Lianyungang Port, Ningbo Zhoushan Port, Xiamen Port, Shenzhen Port, Guangzhou Port, Beibu Gulf Port and Yangpu Port to account for the proportion of new energy and clean energy cluster trucks in 2025 Reach 60%.

With the popularization of charging and battery swapping facilities under the new infrastructure, batteries, motors, electronic controls, charging/battery swapping (referred to as four batteries) have basically matured, and are expected to solve the pain points encountered in the use of loader electrification in the future.

Pure electric vehicles have zero emissions, high efficiency, and obvious energy saving and emission reduction effects. Based on the calculation of 10 hours of operation per day and 300 days of operation per year, the pure electric loader consumes 45KWh per hour, charges 1.5 yuan/KWh, and the annual operating cost is 202,500 yuan; at the same time, the annual maintenance cost of the pure electric loader is 15,300 yuan. Yuan, from this we estimate that within a 5-year period, the operating cost of a pure electric loader will be more than 1.089 million yuan, which greatly reduces energy consumption costs.

Reduce human resource costs and economic losses caused by human operations through automated driverless driving. In theory, it can also achieve 7x24 hours of continuous work, which greatly improves work efficiency.

In the early stages of construction of my country's ports, due to the limitations of electric vehicle technology at the time, all ports did not have designated charging sites for port electric vehicles. With the maturation of electric technology in recent years, the guidance of national energy conservation and environmental protection policies, and the urgent needs of enterprises to save energy and reduce emissions, ports have begun to gradually introduce electric vehicles to replace traditional fuel vehicles. Major battery factories and construction machinery manufacturers have entered the electrification market of construction machinery to promote the development of new energy in the field of construction machinery.

In compliance with the development trend of the port and combined with the current status of the port, Huansheng has realized the application of hard technology, coupled with advanced equipment manufacturing, launched 10kV container-type high-voltage direct-mounted charging station equipment; from 10kV high-voltage access to the container-type integrated charging station, 300kW dual *Single pile, * and * lines are integrated on the container, and two* piles can charge one vehicle at the same time. Split piles, photovoltaic interfaces and energy storage systems are optional to meet large-capacity charging needs.

Our products are integrated integrated equipment. All modules, power distribution systems and charging piles are integrated in the container. It occupies a small area and can be hoisted and moved. With an integrated pre-installation solution, the equipment can be installed on site in one to two days* Completed, the construction is simple, saving a series of construction costs, such as: construction of power distribution room, installation of charging piles, cabinet placement, etc.;

At the same time, it meets the demand for high-power charging. The power of a double* single pile can reach 300kW. If an AC power distribution scheme is used, the full load power cannot be achieved. However, our products use a new DC scheme to achieve 100% full load operation; our equipment There are no AC cables outside, they are all DC cables, which greatly reduces the cost. The price difference between AC and DC cables of the same meter is about 100 yuan; and due to the new internal topology, there are three fewer topological steps than traditional box-type substations, and the loss is The charging loss of the entire station is about 5%, while the loss of box-type substations is about 15%. At the same time, the equipment has a long service life, which can reach 15 years. The overall investment and construction cost is less than that of traditional box-type substations, and the operation return period is shorter. It is shorter than traditional box-type substations, has an average lifespan of 5-6 years longer, and greatly improves profitability; it also meets the needs of new energy access, photovoltaic and wind power can be equipped with DC interfaces, is environmentally friendly, has no carbon emissions, and helps achieve It is carbon neutral, and then flexibly interacts with the public power grid as needed and operates relatively efficiently, mitigating the impact of charging pile electricity on the power grid.

Of course, the equipment can also use the energy storage system to buy low-peak power from the power grid at night or to store electricity generated by new energy sources during the day. During the peak charging period, the energy storage power station and the power grid jointly supply power to the charging station, which not only achieves peak shaving and filling. Valley, it can save the cost of power distribution capacity expansion, and at the same time, it can effectively solve the problems of intermittency and instability of new energy power generation;

According to the April 2020 "Several Measures to Promote Automobile Consumption in the City" and the May 2020 "Shanghai Interim Measures for Promoting the Interconnection and Orderly Development of Electric Vehicle Charging (Swapping) Facilities", the subsidy policy for charging piles, public charging Piles: The basic subsidy for "one-star" degree points is 0.2 yuan/kWh; the basic subsidy for "two-star" degree points is 0.5 yuan/kWh; the basic subsidy for "three-star" degree points is 0.8 yuan/kWh. (The upper limit of subsidy is 1,000 kWh/kW·year)

**Charging piles and battery swap facilities: The basic subsidy for "one-star" degree points is 0.1 yuan/kWh; the basic subsidy for "two-star" degree points is 0.2 yuan/kWh; the basic subsidy for "three-star" degree points is 0.3 yuan/kWh. (The upper limit of subsidy is 2,000 kWh/kW·year). In other words, based on the "Samsung" degree point of Shanghai's first charging pile, the subsidy is 0.3 yuan per kilowatt hour.

Under the trend of electrification and intelligence in global port transportation, improving transportation efficiency and reducing port emissions have become important ways to enhance competitiveness. Huansheng Electric Power adheres to the mission of "technological innovation to realize a green energy future" and adheres to the core values of "service-based, technology-driven, quality-based survival".
