In the context of global carbon peaking and carbon neutrality, the new energy vehicle industry has grown rapidly in recent years, and has driven the development of many supporting facilities such as charging piles.

Recently, a reporter from the "Entering the Industry Chain" column of Core Starlings interviewed Huang Daqiang, Executive Vice President of Anhewei, a leading domestic IGBT charging set company, to discuss the current development of Anhewei under the background of the high prosperity of the charging pile supporting industry. situation and the outlook for the future development of the industry.

A single set of charging set products sells for 500,000-1 million! Has entered the supply chain system of core customers such as power grids.

It is understood that Anhewei was established in 1998 and is the world's leading provider of energy exchange network solutions. The company focuses on the field of digital energy, and has built end-to-end smart energy products, solutions and services in the fields of smart parks, smart grids, charging pile supporting facilities, and energy storage systems. So far, the company has reached cooperation with many well-known companies such as Power Grid, Huawei, ZTE, China Mobile, China Unicom, Shenzhen Airport, etc., and its sales in 2022 have exceeded 150 million yuan.

"Anhewei currently has two major businesses. From 1998 to 2014, the company focused on traditional power business. In addition to undertaking projects of 220KV and below, we also did some such as box transformers, high and low voltage cabinets, etc. Supporting power products to match the implementation of the project; since 2015, the company has used new energy vehicle charging as an entry point to enter the new energy industry. We position ourselves as an 'energy exchange network solution provider', because new energy vehicles In essence, charging is actually a kind of energy interaction." Mr. Huang introduced.

Specifically, in the field of traditional power engineering, Anhewei has long-term experience in power grid construction and service, and can provide customers with power distribution cabinets, low-voltage distribution cabinets, capacitor compensation cabinets, lighting distribution boxes and other power products, and has The construction qualifications of transmission substations and lines, as well as the strong ability to implement resource integration projects, can provide users with high-quality electrical professional installation services.

Mr. Huang said: "Our power projects can be divided into three categories, one is power projects based on power grids; the second is government project projects; the third is private listed company-based projects. Including Shenzhen Airport, Shenzhen Convention and Exhibition Center, Shenzhen Civic Center, Shenzhen Metro Line 3/6/9, Dayang Electric Industrial Park, etc. are all relatively large-scale power engineering projects that we have participated in.”

In the field of IGBT charging, after years of development, Anhewei has formed two series of IGBT charging sets with independent intellectual property rights, namely IGBT super charging set and IGBT variable charging integrated set, which can meet various scenarios and types. vehicles to meet the demand for rapid energy replenishment.Among them, in terms of IGBT super charging sets, with the development of new energy vehicle technology, the capacity and charging rate of power batteries have been effectively improved. In order to match the demand for fast charging, the output power of DC charging piles is also developing in a larger direction. Anhewei has seen the development trend of high-power charging piles a long time ago, and took the lead in launching 300kW, 360kW, 480kW, 600kW and other series of high-power super charging products in the industry.

From the perspective of the large frame, the design of the super charging set is divided into two parts, namely, the front end is equipped with centralized/split AC/DC (space vector control type power conversion device), rectifies 800VDC, and the rear end is equipped with multiple Composed of 60kW DC/DC IGBT charging module and switch matrix, users can be equipped with 5/6/8/10 terminals according to specific needs, and the power can be adjusted at 60kW/120kW/180kW output, which is self-adaptive, has little impact, low power consumption, Extended features.

"This series of products has a very high cost advantage through flexible and adjustable power output, which can help customers save more than one-third of the power investment. For example, an all-in-one machine with 20 120kW charging parking spaces requires a power capacity of 2400kVA. Using group control And charge the IGBT charging set. According to the charging busyness, each charging terminal can be flexibly dispatched at three power levels of 60120180kW. It only needs about 1600kVA of power capacity to meet the charging demand of the same charging parking space, saving about 800kVA of power equipment. Investment. In addition, since the main unit of the charging set can be placed near the box transformer, it can save two-thirds of the cable cost from the box transformer to the charging pile. In this way, the overall utilization rate and operating efficiency of the charging pile will be greatly improved. "Mr. Huang said.

From the research and development of intelligent two-way high-power IGBT chargers in 2015, Anhewei's super charging sets have been used in Beijing, Changsha, Zhangjiakou, Xiamen and other cities since 2018, and by 2020 the company's IGBT super charging integration has become the national " The construction of special charging stations for the CPPCC and the National People's Congress, Anhewei has accumulated many special charging stations for new energy buses in the Beijing Winter Olympics, charging stations in the Beijing-Hong Kong-Macau Expressway service area, and charging stations in Tianjin New Energy Comprehensive Service Center along the way. Successful cases, and have been highly recognized by customers.
