When the customers of the CATL began to delve into the development of lithium batteries, the CATL was uneasy.In the recent capital increase announcement of Avatr, CATL increased its capital by 770 million yuan and became the second largest shareholder of Avatr Technology after Changan Automobile.After the completion of this round of capital increase, Avatr Technology will change from a holding subsidiary of Changan Automobile to an associate, and will no longer be included in the scope of the consolidated statement.Joint ventures are also a new form of China’s new energy automobile companies. Supply chain companies have become one of the shareholders of the new brand. Traditional car manufacturers are the main car manufacturers. At the same time, Avatr’s technology "suppliers" come from Huawei and CATL. On November 15th, the capital increased Avatr officially unveiled its first model, the Avatr 11.Avatr 11 was born on the CHN technology platform jointly created by Chang'an, Huawei, and CATL. The full-stack intelligent solution comes from Huawei. Changan provides vehicle manufacturing capabilities. CATL guarantees the supply chain and exports new battery pack technology. At the same time, Avatr also announced that Chongqing is a global vehicle planning, R&D and manufacturing center, Shanghai is a global brand and software research and development center, and Munich is a global design center. Official delivery quarterly. It can be said that Avatr is a salon that is related to Jikrypton, Zhiji, and the upcoming release. It comes from China's leading independent brand and is positioned as a high-end new energy vehicle brand. However, it is forming a new round of high-end new energy in China in different forms. Competition of car brands. On the day of Avatr 11’s release, the upcoming Great Wall’s high-end electric vehicle brand salon, released four lidars and high-performance mecha battle running positioning, which also made this round of high-end new energy vehicle brand competition gunpowder. Full. These new energy vehicle brands, which are born out of China's leading independent brands, although they are high-end and have similar positioning, they have chosen different paths. Zhiji has an endorsement from Ali, and of course the largest shareholder is SAIC. Although the investors of KKX also have the CATL, they are only strategic partners and do not involve substantial technology output. The same as the previous CATL investment in Ai Chi and BAIC Blue Valley, they are all aimed at strengthening the upstream and downstream cooperation. But Avatr, it was the CATL who took part in the car making. This time, Avatr released its first model, and did not disclose the technical information involved in the CATL. The focus is on spreading Avatr’s brand image-positioned as a high-end lifestyle brand driven by technology, and there is no lack of cross-border information in the release. , Emotional intelligence and other elements. The model was designed by the former BMW designer, Nader Faghihzadeh, who once designed the BMW i8, served as the chief design officer. The published data includes: within 4 seconds of acceleration from 100 kilometers, it supports high-pressure fast charging of 200kW+, has 400tops computing power and 700 kilometers of cruising range. Including the autopilot and the carrying of lidar, not much information was released this time. Avatr 11 is the second model of Huawei inside, so the autonomous driving algorithm and lidar will all come from Huawei. In addition to cooperating with BAIC, Huawei has launched the Polar Fox Alpha S Huawei HI version, and it also cooperates with GAC. With the launch of Huawei inside models one by one, how to bridge the gap between the three will also test the platform capabilities, openness, and tacit understanding of cooperation provided by partners. Through the release of Avatr 11, we can still see that the layout of the CATL in the field of car manufacturing is gradually showing its path.Avatr was not the only tentacles in the CATL that extended to car building. After increasing the capital of Avatr, CATL invested in Nezha Automobile and cooperated with Nezha in technology research and development and supply chain guarantee. CATL has made successive shots in the field of car manufacturing in just a few days. One reason is to promote CTC technology-a battery integration technology that surpasses CTP technology. CTC (Cell to Chassis) technology directly integrates the battery cell in the chassis, canceling the previous battery casing and cover, and integrating with the car chassis. It can not only increase the volume utilization rate and reduce the number of parts, but also improve production efficiency and reduce battery manufacturing costs and improve battery life. For the CATL, participating in car manufacturing is undoubtedly a prerequisite for advancing CTC technology. Because it needs to participate in the vehicle design stage, it has strict requirements on the matching degree of the vehicle chassis and frame model. At the same time, for the CATL, this will also be an opportunity to change the role from a battery supplier to a technology supplier. It will play an important role in the research and development of new cars, and not only protect the supply chain. At the same time, CATL has been caught up in the competition for upstream resources in order to control the cost of raw materials, and high-quality customers have entered battery research and development. It shows that the future business development of CATL may be facing a slight crisis. Although the market value is trillions, it is also It has increasingly highlighted the anxiety of the CATL about business transformation and the urgent need to find new sources of profit. The birth of Avatr has not only verified whether a new form of joint venture can be used in the field of my country's car manufacturing, but also a way out for car manufacturing in the CATL.

The Danish renewable energy consulting agency K2 Management issued a warning in a research report a few days ago that if the UK does not provide more financial incentives to promote energy storage deployment, it may not be able to achieve the goal of adopting 100% clean energy by 2035. K2 Management Company called on the British government to introduce rate incentives to attract investors to provide funds for the deployment of large-scale energy storage systems, and to upgrade solar and wind power assets to a level sufficient to meet the country's energy needs. An analyst at the company pointed out that another solution might be to establish a contract for difference (CfD) mechanism, similar to a system that guarantees the return of solar power generation facilities, without putting public finances into the risk of excessive losses.Compared with the message conveyed by the UK, the host of the COP26 climate change summit, which is keen to demonstrate its clean energy qualifications, K2 Management recently issued a press release stating: “The growth of renewable energy in the UK is at its lowest level since 2010. "The company also called on the UK to take new measures to speed up the development of wind power, and pointed out that the lack of energy storage incentives partly explains why the UK will be short of clean energy power in a decade.Gary Bills, the company’s project manager for Europe, Africa and the Middle East, said: “In addition to planning restrictions on wind farms, the UK also needs to deploy more energy storage systems. In the past few weeks, the renewable energy industry has been driven by high oil prices. As well as the challenges posed by the high energy bills for consumers, they have been criticized. But only through a substantial increase in the mechanism of unlocking the potential of energy storage can renewable energy begin to make meaningful base load power contributions-including a series of financing Energy storage technology.To this end, we must incentivize investment in energy storage technology-through rate expansion or contract for difference (CfD) mechanisms, which enable us to co-locate storage at the locations of new and existing wind farms and solar farms. Energy system, and provide clean energy outside the intermittent power generation window of renewable energy.In addition, it is reported that Queequeg Renewables, a clean energy developer headquartered in London, announced a few days ago that it plans to deploy a battery energy storage system with a total energy storage capacity of 2GWh in the UK. The energy storage capacity of each energy storage system is 20 to 480MWh. The company also plans to Deploy an energy storage system for a solar farm with a total installed capacity of 1.3GW.Queequeg Renewables plans to deploy 2GWh battery energy storage system in the UKAt the latest COP26 climate change conference in Glasgow, London's clean energy developer Queequeg Renewables announced the company's GW-level solar and battery project plan details.Image Credit: Neil Davidson, Low Carbon CommunicationsThe company stated that it is "coming soon" to submit planning applications for the first batch of projects (10-50 MW scale) of the 1.3 GW solar project. At the same time, a 2 GWh "independent" battery factory will be built to provide grid capacity and balancing services. The first project will be built "in the next few months."

There is a new type of Solar array or photoelectric solar cells. The Photovaltaics or simply PV this solar cell is made up of Silicons in crystalline form with little cadmium telluride. And little copper indium sulfide or copper indium selenide. These solar arrays work on the principle of Einstein's photoelectric effect which won him the Nobel Prize. When Sun light falls on these PV solar systems, the device convents the heat energy into electrical energy and thus produces electricity. Semiconductors are used for manufacturing of the PV solar systems. This is because Semiconductors have most number of valance electrons. The process by which these semiconductors are made is known as Czochralski process. These semiconductors are produced using silicon. The amount of electrical energy produced is directly proportional to the number of Solar cells used.The human race should fall back to using the renewable source of power because all the fuels through which we are generating power are all going to run out in another hundred years from now on. So for power generation renewable energy sources are the only one which can provide us a long term solution. The PV solar systems are one such renewable energy source which uses sun as its energy source. The main advantage of this PV solar system is that you can build it yourself. It will be a funny experience as well as exciting experience building the PV solar system ourselves. This kit costs around less that Dollar two hundred; you can also get the manuals from eBay website. You can cut down the cost if you can buy few things yourself from the local hardware stores.Based on your need you can decide the number of solar cells to be used in the PV solar systems. For building a small mobile phone charger one Solar cell will be good enough. You can also add a battery to the design which will store the electrical energy for later use. This PV solar system with the battery gives you more stability because it provides you provision to store the power and provides you a constant output voltage. However, a design without batteries will have fluctuations in its output voltage.More the solar cells more the generation capacity of your PV solar System. To maximize the power generation you need to maintain the angle at which the sun rays falls on the solar panel at ninety degrees. This can be archived by having a motor attached to the panels which can tilt the move it according to the position of the sun and maintain a ninety degrees angle between the panel and the sun rays. This will in turn increase the efficiency of the power generation in the PV solar systems. There are motors available in the market which can turn up to 320 degrees. You can also use reflectors in a large number to focus on one particular solar cell which will also help you increase the power production coefficient.                                

1. Lithium ion batteriesAt present, most electric cars use lithium iron phosphate batteries, but there are several difficulties in popularizing electric cars using lithium batteries: First, the price. Batteries account for more than half of the cost of electric cars, and the latest Tesla cars cost more than 700,000 RMB, out of the reach of ordinary people. Second, energy density. The theoretical specific capacity of lithium iron phosphate battery is 170Wh /kg, and that of lithium cobalt acid battery is 200Wh /kg. So most of the load on a lithium-ion car is the weight of the battery. Third, Security. This still needs to be tested by time, in a long-term perspective. Fourth, charging time. In the quick charge mode, the battery can be 80% full in a few minutes, but the battery will endure relatively severe damage, and there is some danger. Slow charging takes several hours to a dozen hours. Manufacturers generally recommend the slow charging mode. 2. Super-capacitorsThere is no solid evidence of the report that super-capacitors would replace batteries. Although the energy density of the super-capacitors will be greatly improved after the introduction of graphene, it is still much lower than that of lithium ion battery, being only 74Wh/kg. But super-capacitors have the advantages of being quick to charge (in a few seconds) and safe, and can be used for auxiliary regulation of the peak-load and as the storage energy for the brake of electric vehicles. 3. Hydrogen-powered vehicle The technologies of hydrogen-powered vehicles have made great progress in recent years, with advantages of short charging time and strong power. The problems we have to solve for hydrogen cars right now are：   1) The production cost of hydrogen   2) Safe and high-strength hydrogen storage tanks   3) security   4) The price of gas-filled equipment  Among them, the issue of security is particularly important. There is also controversy over whether hydrogen is produced in an environmentally-friendly way.
