Abstract: on February 28, 2020, the article “it’s time to start a new round of infrastructure construction” was released, which caused extensive attention and Discussion on the “new infrastructure” in the market. Subsequently, CCTV news listed the charging pile as one of the seven major new infrastructure construction fields.

1. Current situation of charging pile

The new infrastructure mainly focuses on science and technology, including 5g base station construction, UHV, intercity high-speed railway and intercity rail transit, new energy vehicle charging pile, big data center, artificial intelligence and industrial Internet. As the energy supplement infrastructure of electric vehicle, the importance of charging pile can not be ignored.

The development of new energy vehicles is the only way for China to move from a big automobile country to a powerful automobile country. Promoting the construction of charging infrastructure is a powerful guarantee for the implementation of this strategy. From 2015 to 2019, the number of charging piles in China increased from 66000 to 1219000, and the number of new energy vehicles increased from 420000 to 3.81 million in the same period, and the corresponding vehicle pile ratio decreased from 6.4:1 in 2015 to 3.1:1 in 2019, and the charging facilities were improved.

According to the draft of new energy vehicle industry development plan (2021-2035) issued by the Ministry of industry and information technology, it is estimated that the number of new energy vehicles in China will reach 64.2 million by 2030. According to the construction target of vehicle pile ratio of 1:1, there is a gap of 63 million in the construction of charging pile in China in the next ten years, and it is estimated that 1.02 trillion yuan of charging pile infrastructure construction market will be formed.

To this end, many giants have entered the field of charging pile, and a “hunting” action in the future has started in an all-round way. In this battle for “money view”, ZLG has been working hard to provide high-quality service for car charging enterprises.

2. Classification of charging points

1. AC pile

When the charging power is less than 40kW, the AC output of the charging pile is converted into DC to charge the on-board battery through the vehicle charger. The power is small and the charging speed is slow. It is generally installed in the private parking space of the community. At present, most of the cases are to buy vehicles to send piles, and the cost control of the whole pile is relatively strict. AC pile is generally called slow charging pile because of its slow charging mode.

2. DC pile:

The charging power of common DC pile is 40 ~ 200kW, and it is estimated that the overcharge standard will be issued in 2021, and the power can reach 950kw. The direct current output from the charging pile directly charges the vehicle battery, which has higher power and faster charging speed. It is generally installed in centralized charging sites such as expressways and charging stations. The nature of operation is strong, which requires long-term profitability. DC pile has high power and fast charging, which is also called fast charging pile.

3. ZLG is committed to providing suitable charging point solutions

Founded in 1999, Guangzhou Ligong Technology Co., Ltd. provides chip and intelligent IOT solutions for industrial and automotive electronic users, providing customers with professional technology and services throughout the product life cycle from selection evaluation, development and design, testing and certification to mass production anti-counterfeiting. Zhabeu new infrastructure, ZLG provides the appropriate charging pile solution.

1. Flow pile

AC pile has low technical complexity and high cost requirements, mainly including charging control unit, charger and communication unit. The current stock and subsequent increment mainly come from the purchase of cars, mainly from the car factory supporting. The research and development of the whole charging pile includes the self-study of the vehicle factory, the supporting parts enterprises of the vehicle factory and the supporting facilities of the charging pile enterprise.

AC pile is basically based on ARM architecture MCU, which can meet the functional requirements. ZLG can provide power supply, MCU, communication module products.

The typical block diagram of the general scheme is shown below.

2. DC pile

DC pile (fast charging pile) system is relatively complex, including state detection, charging charging charging, charging control, communication unit, etc. At present, many giants have to seize the market and compete for territory, and the market share needs to be integrated.

ZLG can provide core board, MCU, communication module, standard device and other opportunities.

The typical block diagram of the general scheme is shown below.

4. The future of charging pile

Under the hunting of giants, the charging pile industry is undergoing great changes. From the perspective of development trend, it is inevitable that the number of charging piles will become more and more, business models will be overlapped, and Internet elements will be integrated.

However, in order to seize the market and seize the territory, many giants are fighting their own way, without the concept of “sharing” and “opening up”. It’s hard to share data with each other. Even the interconnection functions of charging and payment between different giants and different apps still cannot be realized. So far, no company has been able to integrate the relevant data of all charging piles. This means that there is no uniform standard among charging piles, which is difficult to meet the consumption demand. It is difficult to formulate a unified standard, which not only makes it difficult for car owners to enjoy the charging experience easily, but also increases the capital investment and time cost of charging pile giants.

Therefore, the development speed and future success or failure of the charging pile industry are determined by whether the unified standard can be formulated to a great extent.
