Hitachi developed a plug-in hybrid with lithium-ion battery – pneumatic cylinder
With the restrictions on vehicle emissions to limit global increasingly stringent, in order to meet the growing demand for environmentally friendly vehicles, Hitachi Ltd. (Executive Officer, President and CEO: Takashi Kawamura, hereinafter called "Hitachi") and the hybrid lithium Development of ion battery manufacturer?? Hitachi Vehicle Energy Corporation (ban served President: Hidetaka Kawamoto, hereinafter called "Hitachi Vehicle Energy") jointly together for the first time developed a Hitachi brand lithium plug-in hybrid ion battery. Hitachi will begin in spring 2010, the domestic and foreign car manufacturers to supply samples.
Plug-in hybrid vehicle (hereinafter referred to as "PHEV") to pure motor driven EV (Electric Vehicle) driving mode and driven by the engine and the motor of the HEV (hybrid) driving mode combined, can greatly improve vehicle fuel consumption, suppress emissions, is considered environmentally friendly car market in the future a big main. Hitachi developed the lithium-ion battery for PHEV is equipped with high-performance, high reliability batteries, also has a high energy (sustainability: sustainable travel ability) and high power (instantaneous explosive) performance characteristics. In the future, Hitachi will market a collection of accumulated experience and the exclusive manufacturing and technological achievements, the product of mass production ready.
The development of the Hitachi battery has the following advantages:
First, large capacity. Has a power capacity of 25Ah, to ensure a pure EV drive motor drive 20 km. Is a hybrid developed in the past (hereinafter, called "HEV") with a lithium-ion battery capacity of 4 to 5 times.
Second, developed to achieve high performance energy (EV driving) and high power (HEV driving) equilibrium of the new electrode. High energy and high power battery designs are often counterproductive to each other, Hitachi electrode active material through the optimal allocation of the composition and the electrode thickness, appropriate adjustments to maintain a high power operation of the conductive material, which has successfully developed two kinds of performance characteristics of both The new electrode.
Third, the use of a heat shield, to prevent internal short-circuit the battery, which greatly improved the safety performance of the battery. Partition is the separation of cells in the positive and negative poles of the while ensuring that the ionic conductivity of the main battery materials, as PHEV battery power capacity than HEV batteries significantly increased, therefore, pay greater attention to product safety assurance. Hitachi uses the temperature of this partition, the partition is applied ceramic technology, and optimized according to vehicle use, developed with the product.
In addition, in order to solve the battery problem size increases, Hitachi also make full use of structure analysis, vibration analysis and other simulation techniques for high intensity of reform and structural adjustments collector. Hitachi Research Institute and machinery together successfully to improve the cell structure and reliability.
In 2000, the Hitachi Group, the world was the first mass production of safe and reliable, high-performance, long life lithium ion battery car, then to the commercial hybrid bus, truck-based, and includes railway rolling stock, including, cumulative total of the market with approximately 900 000 single cells. In order for today's public release of lithium-ion battery for further effective use, in addition to the automotive industry, the Hitachi will also be in the rail, construction and industrial machinery, power storage, industrial and other community groups to develop innovative business applications of the products, this objective, through the combination of battery and control system, to continue to provide customers with the best solution.
Hitachi Automotive Systems Co., Ltd. (ban served President: Kunihiko Onuma) is responsible for sales of Li-ion battery. In addition, Hitachi will be in 2010 March 3 to March 5 at Tokyo Big Sight Exhibition Center in the "First International Exhibition of secondary battery", the public display plug-in hybrid with lithium ion batteries.
The development also applied an independent administrative institution?? New Energy and Industrial Technology Development Organization (hereinafter referred to as "NEDO") part of the commissioned research. Hitachi since 1992, long-term involvement by the Japanese Ministry of Economy and NEDO sponsored by a large lithium-ion battery-related national project, and will continue to facilitate the early application of research findings commissioned the work.
