Lithium batteries are widely used \u2013 for example, in mobile devices and notebooks, the most common gadgets to run on these batteries. By accumulating and releasing electric power in these electronic devices, they make life easier and fun for everybody. Bigger and more powerful, lithium batteries are the main component of recently developed electric cars, such as Nissan\u2019s Leaf. These batteries are being tested in two taxi cabs in S\u00e3o Paulo. Lithium batteries are also a component in hybrid cars with gasoline engines, such as GM\u2019s Volt. These batteries emit very little pollution and this is why they have a powerful environmental appeal, as they have become a source of clean energy in comparison to engines fueled by oil by-products.<\/p>\n

In Brazil, the first lithium battery prototype \u2013 lithium batteries are manufactured by more than a dozen companies around the world \u2013 was manufactured in July by Electrocell, a small company installed in the Center of Innovation, Entrepreneurship and Technology (Cietec), at USP\u2019s Cidade Universit\u00e1ria campus, in S\u00e3o Paulo. Soon thereafter, the battery was installed in a small van \u2013 the Aris \u2013 that can carry 350 kilos of cargo. The silent van is part of a project being conducted by electric power utility CPFL from S\u00e3o Paulo State. The Aris van was made by Edra, a producer of special cars in the city of Rio Claro (SP). Initially equipped with batteries made in China, the vehicle, now equipped with a Brazilian-made battery, may become commercially feasible for specific niches, such as CPFL, to deliver mail, transport electronic equipment, or deliver ingredients to restaurants.<\/p>\n

\u201cWe have already identified the partners of the entire automotive technology chain,\u201d says Fl\u00e1vio Eduardo Lopes, director of Edra. Building a factory to manufacture electric vans will require investments of R$ 10 million to produce one thousand units a year. \u201cIf we manage to achieve this production, and taking into account that the battery costs half of the price of the vehicle, it\u2019s possible that each Aris can be sold for about R$ 60 thousand,\u201d says Lopes. \u201cThe vehicle is feasible, though it is more expensive than similar dual fuel vehicles, because each battery is expected to last for 10 years, the equivalent to driving a car for 300 thousand kilometers.\u201d The vehicle can reach up to 80 kilometers an hour and needs to re-charge the battery every 100 kilometers. It takes the Aris up to seven hours to recharge the battery plugged into a standard 200-volt outlet.<\/p>\n

A higher number of electric vehicles is expected to become part of the planet\u2019s total fleet, slowly and steadily. In the United States, according to a study on the production of lithium ion batteries, conducted at Duke University\u2019s Center on Globalization, Governance & Competitiveness, published in October 2010, hybrid or electric cars and vans are expected to account for more than one half of new car sales in the U.S. market by 2020.\u00a0 In the conclusion of the study, the researchers, headed by Marcy Lowe, state that the automobile industry is moving away from gasoline engines to invest in electric motors and that the key element for this change is the availability of advanced lithium batteries. \u201cThe United States must be able to produce lithium ion batteries to remain competitive,\u201d the study warns.<\/p>\n

The global battery market is expected to react soon, according to the estimates of the German consulting firm Roland Berger. As stated in a report published early this year, the lithium ion battery market for automotive use is expected to total more than US$ 9 billion by 2015. In the restricted field of advanced batteries, used in electric systems and equipment, the market is expected to total US$ 7.6 billion in 2017, according to Pike Research, a U.S. consulting firm.<\/p>\n

The market for batteries in electric systems is another business that Electrocell is focusing on. In the so-called smart grids, consumers \u2013 especially companies \u2013 will play a leading role in monitoring and managing the electric power consumed. Each consumer will be able to generate and distribute his own power through solar or wind-powered systems, for example, and electricity may be accumulated in lithium batteries. The batteries can also be charged during non-peak hours, such as the very early morning, for instance, when power rates are cheaper, rather than during peak hours, which run from 7:00 pm to 10:00 pm, when the rates are higher. To become fully functional, smart-grids still depend on specific laws in Brazil.<\/p>\n

According to the Center of Management and Strategic Studies (CGEE), linked to the Ministry of Science and Technology (MCT), 178 smart grid projects have been registered in R&D programs coordinated by the National Power Agency (Aneel). In December 2011, the Center presented the paper Redes el\u00e9tricas inteligentes: contexto nacional <\/em>[Smart power grids: national context], with a list of 178 smart grid projects. The smart grid projects encompass such items as intelligent power metering services, and the generation and distribution of electricity in micro-grids, specifically, for instance, for a company running on solar or wind power systems. The 178 projects account for investments of R$ 411 million. Data collected and analyzed by the CGEE shows that China, South Korea, the United Kingdom, and the United States lead the financial forecasts for projects focusing on the modernization of the respective power grids. By 2030, investments in these smart grids is expected to total US$ 178 billion.<\/p>\n

Electrocell plans to build a plant in 2030 to manufacture lithium ion batteries to participate in the national smart grid and electric car markets. \u201cWe are negotiating the investment funding with venture capital firms and investment banks,\u201d says engineer Gilberto Jan\u00f3lio, a partner in Electrocell. The company went into business in 2000, with a fuel cells project, a battery that produces electric power from hydrogen. The project was funded by FAPESP\u2019s Innovative Research at Small Companies Project (Pipe) (see <\/em>Pesquisa FAPESP n\u00ba. 92<\/a> and n\u00ba. 173<\/a><\/em>).<\/p>\n

Developing the battery in Brazil was a challenge for Electrocell. It took the company a year and a half to produce it. \u201cIt was an integrated engineering development; we defined the control and the equilibrium of the electric charge of each element in the battery and the arrangement of the entire set. All of this was done in line with the car\u2019s control software. We also worked on collision and vibration engineering,\u201d says Jan\u00f3lio. \u201cAnother major factor was the development of a suitable ventilation system for the country\u2019s warm climate,\u201d says Volkmar Ett, another partner in Electrocell. To manufacture the batteries, the company partnered with Cegasa, a Spanish enterprise that manufactures batteries and set up business in Brazil two years ago. In Spain, Cegasa develops experimental batteries for the Spanish car company Seat, controlled by Volkswagen. \u201cThey supply us with the lithium wafers and we build the battery,\u201d says Jan\u00f3lio.<\/p>\n

The market for these batteries includes hybrid buses with electric and conventional engines, small trucks, company data processing centers, and unmanned aerial vehicles (UAVs). \u201cWe have received many orders, and all we need to do now is to produce the batteries in series,\u201d says Ett. The company\u2019s business plan, prepared by consultant Luiz Carlos Rocha Paes, foresees the manufacturing of 213 batteries for vans, buses and small motorcycles in 2014. Sales estimates amount to R$ 25 million. \u201cBut the predicted demand potential in 2014 is 966 batteries, which will probably be complemented by imported batteries,\u201d says Paes. \u201cWe believe that Electrocell may achieve a 22% market share,\u201d he says.<\/p>\n

In the case of CPFL, which first built electric cars in 2009, the Brazilian-made batteries guarantee the continuity and progress of the project. \u201cFor CPFL, electric cars exemplify the technology that enables us to find out how this technology works on a daily basis. This is not an R&D project; we want to show that it is possible to manufacture electric cars in Brazil and we have already bought four Aris cars,\u201d says engineer Marcelo Rodrigues Soares, coordinator of the project at CPFL. The company invested approximately R$ 3 million for the purchase of the cars and the batteries. \u201cOur tests showed us that the cost of driving this electric vehicle is equivalent to one-fourth (1\/4) of the mileage we get from a vehicle that runs on gasoline,\u201d says Soares. The Aris has been ratified by the National Transit Department (Denatran) since March 2010 and can travel all over the country.<\/p>\n

In spite of the favorable outlook for this new market, the price of the batteries is expected to drive some consumers away. \u201cIn Brazil, we need to see how much more consumers are willing to pay than they pay for a vehicle with a gasoline engine, for example, in order to have a more efficient way of reducing CO2 <\/sub>emissions,\u201d says Francisco Nigro, a professor at the Polytechnic School of the University of S\u00e3o Paulo (USP) and technical advisor to the S\u00e3o Paulo State Bureau of Economic Development, Science, and Technology. \u201cThe prospects indicate that going forward, the price of the battery will drop and the equipment will become more feasible for the automotive market,\u201d Nigro explains.<\/p>\n","protected":false},"excerpt":{"rendered":"Lithium-based equipment developed in S\u00e3o Paulo to drive vans ","protected":false},"author":10,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[169],"tags":[227,228],"coauthors":[97],"class_list":["post-50053","post","type-post","status-publish","format-standard","hentry","category-technology","tag-energy","tag-engineering"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/50053","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/10"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=50053"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/50053\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=50053"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=50053"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=50053"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=50053"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
