Hanergy Group: Solar powered vehicles will go to civilians

Hanergy, which has the core technology of thin film power generation, is willing to make solar vehicles go to civilians in a win-win and win-win cooperation.

During the Guangzhou International Auto Show, the Hanergy Solar R solar-powered car was unveiled. As the first solar car at a professional car exhibition, Hanergy Solar R has received much attention as soon as it is on display. In order to make the price of solar cars civilian, Hanergy Car specially invited a number of industry experts to discuss whether solar energy technology can solve the current environmental protection dilemma of the car and how to let solar cars enter each family at a civilian price. Zhang Bin, senior vice president of Hanergy Holding Group, said: "We are willing to promote the further development of solar vehicle business in various forms such as suppliers or OEMs. As Li Hejun, chairman of the board of directors of Hanergy Holding Group, said, we have to be ordinary people. A solar car that can afford it."

For the topic of this discussion, Yin Chengliang, deputy dean of Shanghai Jiaotong University Automotive Engineering Research Institute, said that the combination of solar energy and automobile is in line with the development trend and can solve the environmental dilemma of new energy vehicles in the future. With the further improvement of solar power generation efficiency and the increasing popularity of automotive lightweighting, solar vehicles can quickly move toward larger-scale industrialization.

With the intensification of environmental protection issues, new energy vehicles are receiving more and more attention. When discussing what kind of energy-powered vehicles will become a car that can break through the environmental dilemma, Han Xiaoping, chief information officer of China Energy Network, pointed out: "Hydrogen energy is a secondary energy source. In the process of hydrogen energy production, it also causes indirect environmental pollution. The future is better for solar energy."

In the current development of new energy vehicles, there are many new energy vehicles such as hydrogen fuel cell vehicles, plug-in pure electric steam, and solar power vehicles. There is some pollution in both the process of generating electricity and the production process of hydrogen raw materials. According to Han Xiaoping and Yin Chengliang, the production process of hydrogen fuel is roughly divided into two types, one is produced by decomposition of methane, and the other is directly produced by electrolysis of water. The production process using methane as a raw material will cause a certain degree of environmental pollution to emit carbon dioxide into the atmosphere; in the process of producing hydrogen by electrolyzed water, electric energy is required. Judging from the current development situation in China, the source of electricity is still mainly based on thermal power generation, so it will also cause environmental pollution in the process of producing electricity.

In order to prove the advantages of solar energy, Han Xiaoping shared a set of data for the people present: under the current technical conditions, the effect of charging electricity into the battery is 90%, and the effect of converting electrical energy into kinetic energy is 90%, a national average. The level of coal-fired power plants has a power generation effect of 38%, so that the overall conversion efficiency is 30%, while the conversion effect of fuel vehicles is only 17%. In view of the utilization of solar energy by Hanergy's power generation technology and the current energy utilization rate of new energy vehicles, solar energy vehicles have the highest energy efficiency, and the solar energy utilization process does not cause environmental pollution like hydrogen and electricity production processes. Pollution.

Thanks to the 31.6% solar conversion rate of GaAs thin film power generation technology, Hanergy Solar Power Vehicle has rid of the dependence on charging piles to the utmost. Under ideal lighting conditions, the solar cells can save 8~10 kWh when exposed to sunlight for 5 to 6 hours. On average, they can drive the car for about 80 kilometers per day, and drive more than 20,000 kilometers per year, which can meet the needs of the city's regular transportation.

Although sunlight is the main source of energy for solar cars, users do not have to worry about their cruising range under conditions of poor lighting conditions. Under the rainy weather or long-distance travel demand without sunlight, the conventional lithium battery energy storage battery equipped with Hanergy Solar Power Vehicle can also be charged with charging pile, the maximum endurance capacity is 350 kilometers; in the case of light, continuous driving process In the middle, the car can also “fill and charge”, and the mileage of continuous uninterrupted driving is 10%~15% more than that of ordinary electric vehicles.

Perhaps as Yin Chengliang said, “Despite the current shortcomings of solar power technology, it is correct in terms of trends. In the future, it will be completely replaced, or most of it will replace the current power source. As the solar energy conversion rate is higher, the electric energy consumption is lower. The dependence of the Hanergy solar power vehicle on the charging pile will be smaller and smaller, and even the requirement of “no plugging, moving up” can be achieved. This is also the direction that Hanergy has been moving forward.

Of course, a qualified solar-powered car is only environmentally friendly and has a long battery life. The goal of Hanergy is that everyone can afford it.

For the future positioning of Hanergy Solar Car, Zhang Bin said that while the solar car is positioned in the high-end model, it should also be based on ordinary household models. It is no longer a toy for the rich, but a future technology that ordinary people can experience. In order to reduce costs, Hanergy has come up with many options. First, accelerate the transformation of equipment localization, give full play to the domestic comprehensive cost advantage, and reduce costs; secondly, benefit from large-area epitaxial layer stripping technology, and independent MOCVD (a new type of vapor phase epitaxy technology) high-speed deposition technology, as of now, The cost of Hanergy's GaAs thin film chips has dropped significantly, making the commercialization of this technology possible. It is reported that Hanergy GaAs battery has been widely used in high-altitude drones, aerospace and other commercial fields, and has been recognized by the market and customers, which laid the foundation for closer integration of GaAs technology and automobiles.

Zhang Bin believes that after the popularity of photovoltaic technology, the cost of future gallium arsenide thin film solar chips will drop to 1 US dollar / watt. If a car can be laid with 6 square meters of solar panels, then its cost is only 1800 US dollars (12,000 yuan) than ordinary electric vehicles, which is only equivalent to the fuel cost of a regular gasoline car for one year. With the breakthrough of core technologies, the cross-border application of chip components and the mass production of solar vehicles, the cost of solar-powered vehicles will be greatly reduced, so that ordinary people can afford them.

As Zhang Xiang, a well-known commentator in the automotive industry, said: “Although solar cars have not entered the public eye for a long time, in fact, solar technology has already developed over a decade or two. The solar car market is now nearing the outbreak. If in this outbreak period, whoever grabs the opportunity, whoever will go to the forefront in this market."

In order to take the lead in the field of solar vehicles, Hanergy is willing to cooperate with others on a completely open platform. In this seminar, Zhang Bin said that Hanergy can be used as both a component chip supplier and a host car manufacturer. If someone needs a supplier, Hanergy can provide components, chips, and match. If a strategic investor feels that Hanergy's things are good, Hanergy can also make automakers to produce cars.

"Since the release on July 2, Hanergy has experienced a very short time. In the future development plan, we are willing to use the open platform to do the car. In order to promote the future development of solar cars, we are willing to win-win. The attitude is to contribute to the new technology." Zhang Bin said.
