The 12th China (Wuxi) International New Energy Conference and Exhibition will be held in Wuxi from November 4th to 6th. The theme of this conference is "Low Carbon, Smart and Efficient". In terms of exhibitions, new products and technologies in the fields of solar photovoltaics, smart integrated energy, energy storage, photovoltaic bracket hydrogen energy, industrial park energy conservation, and new energy vehicle charging piles are showcased.

On the morning of the 4th, shortly after the conference began, many people came to visit the exhibition hall. At the booth of Longma Technology, a staff member was introducing a home energy storage system to visitors. When they heard that the system would be installed at home and generate electricity for their own use, many citizens gathered around and expressed their interest.

A 10 square meter roof can install components with a power of 1.5kw to 2kw, and the cost of 1kw is around 3200 yuan. In the Jiangsu Zhejiang Shanghai region, 1kw modules generate an average of 3.5 kWh of electricity per day. Calculated at an electricity cost of 0.5 yuan, the annual power generation revenue of 1kw modules is around 650 yuan. The government also provides a power generation subsidy of 0.18 yuan per kilowatt hour, which can be recouped in 4-5 years. ”Xiao Rong, the key account manager of Longma Technology, introduced that due to the lack of mechanical potential energy in photovoltaic power generation, there is no need for mechanical operation and maintenance after installation, and ordinary people can fully grasp the operation of the power station. In addition, with the development of photovoltaic power generation in China for many years, the technology has become very mature. The components have a 25 year power generation efficiency guarantee, the inverter can be guaranteed for 10 years, and the bracket cables are basically worry free unless they are damaged externally. So, if citizens have the conditions to install photovoltaics, it is equivalent to spending money on financial management at home for 5 years. After 5 years of capital recovery, as long as there is sunlight in the remaining time, they can earn an extra income.

In the new energy vehicle exhibition area, an 8-meter-long pure electric bus has attracted the attention of many citizens. Its appearance is roughly the same as that of a regular bus, but it is designed to be more dynamic and fashionable, and the seats inside the car are also simpler and more beautiful. Citizens can enter it to visit and learn about it.

The advantage of our electric bus is that it is independently developed from the motor to the controller, which is more energy-efficient in terms of energy consumption. With the same amount of electricity, it can travel further, "said Li Zhiyong, electrical designer at CRRC Times Electric Vehicle Co., Ltd. The vehicle also has a" Yunzhitong "vehicle operation management platform, which provides 24-hour cloud monitoring and protection. It can monitor the vehicle's status and whether it is safe during operation. Once a fault occurs, the backend will respond immediately. The noise reduction effect is also very good, with a vibration isolation rate of over 90%, which can bring passengers a "deep sea level" quiet experience.

With the increasing popularity of electric vehicles, people are pursuing more comprehensive charging station services. At the booth of Wuxi Municipal Public Industry Group, the charging operation system was displayed. This visual charging operation management platform is based on the Internet of Things platform to achieve digital intelligent control, implement 24/7 control of intelligent charging terminals, efficiently eliminate faults, ensure the normal operation of charging facilities, and reduce operational risks.

Our main focus is on service, with a focus on providing users with high-quality services, "said Mr. Fang, a staff member of the operation department of Wuxi Municipal Public New Energy Technology Co., Ltd. The company has a complete power supply system and can achieve integrated management of parking and photovoltaic bracket charging through big data integration. At present, there are more than 200 charging stations built in Wuxi, with about three to four thousand charging piles of various sizes. Since its operation at the end of 2015, the charging capacity has been increasing year by year, from a few hundred kWh to tens of thousands of kWh.

Online management is also our highlight, "Mr. Fang said. In the past, due to being able to use it offline, there were many cases of overcharging or undercharging. Now, with online management, it is not possible to use it offline, ensuring the interests of consumers. In the future, value-added services such as car washing will be added to charging stations with conditions, and fully equipped rest rooms will be built to provide users with more convenience.

At the booth of State Grid Corporation of China, a small blue robot is constantly "walking" back and forth, about half a meter high, looking very cute. After reading the introduction on the side wall, I realized that such a mini looking robot actually has great uses. They are usually used to complete inspection tasks in high-voltage substations with tens of thousands of volts.

Mr. Hua, a power supply worker in Wuxi, introduced that many substations have large spaces and multiple inspection points. Manual inspection is not only inefficient, but also a great challenge for inspection personnel in adverse weather conditions. Especially when people are distracted and tired, they will encounter various difficulties. However, using inspection robots is much easier. Robots do not need to rest, and can work for a week on a single charge. As long as the program is designed properly, they can conduct inspections 24 hours a day and night.

Mr. Hua said, "With laser navigation, photovoltaic bracket ultrasonic obstacle avoidance, intelligent path planning, infrared temperature measurement, and full drive omnidirectional inspection, in the past, if it was a weekly inspection, there were often situations where problems were not discovered in a timely manner. With the intelligent inspection robot, as long as the program is set up, it can work every day. In case of heavy fog, rain and snow weather, the inspection frequency can be increased to diagnose the equipment in real time.
