universal access in the electric car before the lithium-ion rechargeable batteries, giving rise to intense price competition. Tornado is blowing prices LG Chemical Company. The company began to auto manufacturers reported a portable battery with the same price. The other car battery manufacturers will be forced to follow suit. Lithium-ion rechargeable battery with a car which became fully listed. Fujitsu Siemens BTP-C7K8 Battery In January 2011 24 to 28 at the International Conference on the car battery present, car manufacturers have started from a number of companies purchasing lithium-ion rechargeable battery (Figure 1). Toyota said that apart from the procurement of Sanyo Electric, will also in the Toyota subsidiary Primearth EV Energy (PEVE) mass production of lithium-ion rechargeable battery 1). Note 1) at Toyota in November 2010 at the Figure 1: Two more companies from the major automobile manufacturers purchase batteries major automobile manufacturers from a variety of lithium-ion battery manufacturers, rechargeable battery procurement trend is growing. In addition, although Renault - Renault Nissan Group has been from Nissan and NEC joint venture Automotive Energy Supply (AESC) the amount of procurement of all lithium-ion rechargeable battery, but also accept the South Korean LG Chemical supply. other companies too. With GS Yuasa and Mitsubishi Corporation jointly set up Lithium Energy Japan joint venture battery of Mitsubishi Motors, also announced that its commercial models of electric vehicles (EV) will use Toshiba’s lithium-ion rechargeable battery. major reason for car manufacturers to accelerate the company purchases from more than two lithium-ion rechargeable battery, because before the popularity of electric vehicles, lithium-ion rechargeable batteries, the reason prices have declined rapidly. two main reasons. The first EV and plug-in hybrids (PHEV) is rapidly entering the market. LG Chemical Company is to carry out another price war. Regarding the first reason can be explained as follows: Prior to the mainstream has been the electric hybrid vehicle (HEV). HEV is equipped with a lithium-ion rechargeable battery capacity is only about 0.5kWh ~ 1.5kWh difficult to obtain the cell mass production effect. For this reason, car manufacturers need to share a variety of models of batteries to increase usage. Therefore, to get the battery production effects, the best possible purchase products from a battery manufacturer Note 2). Note 2) In fact, Toyota for use in HEV NiMH rechargeable battery is a purchase from the PEVE. However, EV and PHEV is entirely different. Each with a capacity of EV batteries around 20kWh, PHEV is 5kWh ~ 16kWh around, jumped to 10 to 40 times HEV. If the premise of selling discount car, car manufacturers launch a model can be obtained only mass-produced the battery effect. http://blogleaf.com/tpbatt/2011/05/03/shanghai-digital-tv-broadcasting/ put into action is the Nissan. The company’s annual output of 50 000 initially developed as a precondition EV battery production plans, from the early stages of trying to lower the price. Nissan plans an annual output of 20 million units by 2012, the scale, if realized, then the battery cost LG Chemical launched a price war such a large scale of production, Nissan can achieve 2 to 3 years, and substantially reduce the battery cost? In the battery when the industry is still scratching their heads, LG Chemical’s move is even more surprised that around. LG Chemical has recently received a series of orders for large car manufacturers. In this regard, the battery industry have pointed out, LG Chemical is South Korea and the United States built a large-scale production car battery factories, said the current offer is a production plant in the cost of production is the prerequisite for strategic price. LG Chemical’s position in the case of growing, many point of view, as in lithium-ion rechargeable battery business of Samsung SDI, and SK Innovation and other Korean companies will also offer their own reduced to LG Chemical equal level. In addition, in view of this, car manufacturers have increased the procurement of battery manufacturers, there is no doubt that this will enable the formation of competition between enterprises, the battery manufacturers into a more intense price competition. United States and China manufacturers battery manufacturers in order to cross this bridge, we must ensure that the supply of content. To this end, the U.S. battery manufacturers began to seek answers to the Chinese Fujitsu Siemens 60.4H70T.001 Battery market, China is actively promoting cooperation between automotive manufacturers. Ener1 A123 Systems and the United States were planned and the Shanghai Automotive (SAIC Motor), and China’s largest auto parts manufacturer Universal Group (Wanxiang Group) to establish joint ventures Note 3). Note 3) Ener1’s merger of its manufacturing operations in EnerDel battery company. China has emerged as the world’s largest auto market, on this basis, the Chinese government’s EV policy is also very compelling. To this end, the U.S. battery manufacturers plans to first seize an early lead by the government policy to import buses, rental vehicles and commercial vehicles and other battery needs of the business opportunities, but also in the layout of the increasing demand in the United States, of the power storage for power grid stability system with a large battery market to ensure supply. concern is the movement of Panasonic and take active measures to ensure the number of U.S. companies in contrast, the Japanese battery manufacturer. In addition to the Japanese manufacturer Nissan Motor in Japan said the United States and Europe will quickly build lithium-ion rechargeable battery production base, other manufacturers have not been in action overseas. Sanyo Electric will be included as a wholly owned subsidiary of Matsushita also surprisingly slow to act. Garcia City, Hyogo Prefecture, Sanyo Electric is building a large unit with a car battery production plant, is generally believed that Sanyo Electric Fujitsu PA3349U-1BAS Battery will supply the German Audi as the beginning of the year 2011, Toyota will begin to supply. People thought that the Matsushita Group may face such a large unit of global sales, but in fact, Panasonic’s battery operations department is actively promoting the use of in-car laptop battery unit with a cylinder, Panasonic launched in 2008 by 6800 due to laptop battery unit EV In Japan, Panasonic plans to Zero Sports Supply 18650 cell battery pack, and Zero Sports of Japan Post Group will supply 1000 by a commercial motor vehicle adapted from EV. However, Sanyo Electric Tesla Motors already available to the 18650 battery cell, and then deliberately do not see the Panasonic with its need for cooperation and equity. Panasonic as the most pressing issue is how to deal with automobile manufacturers around the procurement in the United States and Europe. Governments on the automotive industry the strict requirements of local procurement and consumption of products is quite different, we must take countermeasures as soon as possible. Dell Vostro-3700 Battery lithium-ion battery cars have unveiled details of the battery pack open look at the current auto market, passenger cars since 2011, started full use of lithium-ion rechargeable battery (Table 1). Japan’s auto makers, following the start HEV battery. Toyota intends to market the hybrid from 2011 began to use lithium-ion rechargeable battery, also expressed a listing in 2012, PHEV and EV equipped with intention. and Honda in addition to the spring of 2011, listed in the United States, . In this context, the car battery the International Conference At the meeting, car manufacturers and battery makers new vehicles will be made public or may be equipped with lithium-ion rechargeable battery details. which, Audi mid-2011 for reservations listed HEV The car is the Volkswagen Group including Audi, including the first with a lithium-ion rechargeable battery of the vehicle. In the single-motor hybrid system at the same time, engines and motors can be clutch, EV driving motors can be used only 3km (Fig. 2). Figure 2: The Sanyo Fujitsu PA3424U-1BRS Battery lithium-ion rechargeable battery Audi’s To prevent battery deterioration, batteries with the same cooling system and air conditioning. (Photo: Audi Japan) lithium-ion rechargeable battery pack manufactured by Sanyo Electric, the capacity is 1.3kWh. Voltage is 266V. Weight 35kg, overall battery energy density 37Wh/kg, the output density 1143W/kg. Unit share of the battery weight ratio of 52%. With 72 units, so unit capacity of approximately 5Ah, voltage is 3.7V. Can be inferred from the voltage, the cathode materials based on ternary system, it is estimated the energy density of 70Wh/kg unit around. Audi battery system is characterized, in order to improve the battery life, the unit implemented a complete thermal management. Batteries in 3 stages of cooling control. When the battery temperature is above 34.5 ℃, it will start the car air-conditioning.超过 37 ℃, the Council passed the front of the vehicle air-conditioning evaporator (Evaporator) for cooling air to the battery pack. When the temperature rises above 42 ℃ to continue, it will stop the vehicle the front of the air, and start the battery pack cooling system installed on the evaporator. In addition, the battery unit by optimizing the configuration and cooling air flow path, can be battery temperature difference within the control Fujitsu Siemens BTP-CAK8 Battery unit at the highest range of 5 ℃. Security, with regard to the internal mixing unit carried out a foreign body within the short-circuit test, confirmed the fire and explosion will not occur. In addition, if a thermal runaway or other abnormal cell battery system will be closed when, in addition to setting the exhaust port, to be discharged from the battery unit of gas produced.
