Use of charging facilities for professional bus terminus fast charge, 50% half-hour of electricity can be filled, and the installation of solar panels on the roof, in the process of moving can also provide auxiliary power life for battery charging. The full use of energy, dell Inspiron 630m battery K 9 true zero emissions, fuel consumption, fuel cost less than similar vehicles 1 / 3.
Schematic diagram of the Japanese large-scale energy storage battery
(A) Shin-Kobe Electric (Shin-Kobe Electric Machinery Co.)
Shin-Kobe Electric, Hitachi Manufacturing Department is responsible for the production of industrial lithium battery division. The display by the large energy storage battery is more special, as shown in Fig's LL-W type of large lead acid storage batteries. This module Besides general storage function, but also can be used to mitigate the wind generation system activated, the resulting system instability. Figure III shows the overall specifications of size 437 × 799 × 500 mm, voltage of 8V, the current up to 1500Ah, electric capacity of 12kWh, priced at 400,000 yen. The single group of about 2MW wind power generation, based on some of the electrical storage devices need 1.3MWh, it projected the overall LL-W module, about 432. And the Kuroshio current (Kuroshio) wind company, has actually set in five Kawahara Aomori City to match the total 16MW of wind power. dell Inspiron 640m battery
In addition, the Shin-Kobe Electric is also responsible for the storage of electrical energy on display in the battery module-LL (available for solar or wind) module and LL-S (for solar) modules, individual specifications as shown in Table I. Different from the LL-W-type module is configured to wind power or solar 99kW 100kW of power generation equipment, it will be paired with 584kWh energy storage battery, converted into the module takes about 292 LL1000, the overall battery energy storage equipment, build, nearly 6,000 million yen budget.
(B) ELIIY POWER
ELLIY POWER is in Japan, quite a large lithium-ion batteries are promising energy storage company. First by the Keio University in 2003 in a ELiica electric vehicle project initiated and nearly 30 companies one after another to join this project. Later in 2009, by Sharp, Daiwa House Industry, and other enterprises, raising 10.16 billion yen established and publicly listed.dell Y9943 battery In the same year announced the establishment of lithium-iron battery technology will be used for family and other large storage needs of the factory. Which, by Sumitomo Osaka Cement (Sumitomo Osaka Cement Co., Ltd.) Lithium iron phosphate cathode material provided powder. The Sumitomo Osaka Cement, lithium iron phosphate in the promising prospects, will significantly expand production capacity in 2011, the lithium iron phosphate from the original 150 million tonnes, a substantial increase to 1,000 to 2,000 million tonnes.
Figure IV for the exhibition on display in the ELIIY POWER related to the large energy storage system. Figure IV on the right as the main battery module, containing four lithium batteries Cell. Module specifications for the 192 × 175 × 128 mm, weighing about 2kg, the energy density of 91 Wh / kg. Figure IV on the left of the EPSS 8kWh system requires 8 modules.
ELIIY POWER in 2010, will produce 200,000 lithium-iron battery Cell, mainly for large-scale energy storage. In addition, the lithium-iron battery energy storage module in the actual setting, the majority of co-operation with local government, set up in schools, local administrative agencies, dell RC107 battery other private enterprises to adopt the ratio is very low.
(C) MAXWELL
MAXWELL 3C and hand tools on display many of the lithium-associated module.
Of the most notable was undoubtedly used in large super capacitor energy storage module. This BMOD0063P125 module, due to the characteristics of high-speed charge and discharge. There are two application conditions. First, the general large-scale wind power generation and lifting equipment, this module can provide the required moment to launch a large current. Or is the current generated when the large number of power generation, this module can be a buffer device follow-up energy storage devices.
In general, single-group 2MW wind power generation equipment, requiring only a super capacitor module. This module, for example, contains 18 super-capacitor Cell, the overall module size, as shown in Figure Six, the size is 619 × 425 × 265 mm, voltage up to 750V, maximum current of 750A. But its price is quite high, about $ 405,000. dell Latitude D620 battery
Large energy storage battery option is to go hybrid combinations
In general, large-scale renewable energy storage device and carry quite close. Operation of renewable energy, for energy storage devices, also have different functional requirements. To wind power, it can be divided into "instant activation" and "Hang Time Storage" in demand, as shown in Figure VII. The "instant activation" of the demand, the attention is the moment of charge and discharge energy storage devices and high security. And "Hang Time Storage" focus, it is stable and lower energy storage security requirements.
In the exhibition of large energy storage battery related to the process of inquiry can be found in the overall price gap is quite big. Therefore, large-scale energy storage can be expected in the future in the process of building. Will be a combination of hybrid batteries. dell 312-0386 battery
Currently speaking, the instantaneous charge and discharge efficiency, super capacitor or a first choice, but recent price of millions of NT dollars. May make renewable energy in a single device, equipped with only a super capacitor module. In addition, a recent topic of great car ternary cathode material of lithium batteries, in its performance under high efficiency may also be applied to the "instant activation" requirements.
Finally, in "constant when the energy storage" aspect, in the setting of limits, the energy requirements and battery performance, not as harsh automotive lithium batteries. At present, we find that firms tend to use less expensive battery types, such as lead-acid batteries, nickel metal hydride batteries and so on. The lithium-iron batteries, lithium batteries are hoping in the car driven by economies of scale,dell PC764 battery it can be priced lower, to apply to large-scale energy storage.
