Hybrid manufacturing cost reduction

Indian research company RNCOS released a forecast this week that from 2008 to 2015, the global hybrid car market, the average annual growth rate of 12%. Toyota and Honda hybrid cars will lead the global market. In Japan, Honda has already begun efforts to reduce the cost of hybrid cars, and Nissan follow Toyota and Honda in developing hybrid products, while focusing on development of electric vehicle products.

Honda lower half of the power system

Kondo, vice president of Honda widely on behalf of a director, said recently that Honda is scheduled for early 2009 a dedicated hybrid car. The model currently in development progress. Toyota Prius will become a direct competitor.

Kondo said the car the cost of hybrid systems can be reduced to about half the Civic Hybrid. The key to cost-cutting system of small, lightweight and simple structure.

Dedicated hybrid vehicle hybrid system uses the existing models use "IMA" (IntegratedMotorAssist, Integrated Motor Assist). For special vehicle for the development of hybrid IMA, through a thorough revision of its design, more the pursuit of small, lightweight and simple construction, can achieve significant cost reductions.

The dedicated hybrid vehicle back for the 5 5 cockpit car, size, located between the Fit and Civic. Design with fuel cell vehicle "FCXClarity" concept, suitable for home use.

Dedicated hybrid car is expected to sell in one million to two million yen between (about RMB 62 000 -12.5 million). Allegedly, Toyota proposed a "hybrid makes a sound business to be" objective, the company started early to reduce the cost of hybrid systems for effort.

Honda official said American companies, Honda is expected to produce about 20 million units worldwide back the new tank cars, of which about 100,000 will be exported to North America. Honda's new hybrid lower than the selling price of the Toyota Prius.

Nissan car market in 2010

Nissan Motor in August advanced technology that will be held, open the test is developing hybrid vehicles, scheduled in 2010 in Japan and the United States.

Test vehicle for the parallel hybrid, the luggage compartment is equipped with a lithium-ion rechargeable battery, motor and gearbox with the use of double-clutch. Which the Skyline as an experimental prototype of the hybrid models, the estimated production in 2010 will use other models.

The hybrid system developed for the parallel hybrid system. The engine and transmission system with a balance between the motor and drive and renewable generators, the input and output side of the motor is equipped with a clutch, respectively. With different driving mode, the motor and two clutches can be switched in order to achieve the motor vehicle, engine running and deceleration energy recovery.

Nissan did not disclose the power of the motor, it is estimated with the previously reported compared to other companies, such as motors, the power of about 10 to 20 kilowatts. The capacity of lithium-ion rechargeable battery has not been released, but the capacity of the Toyota Prius than 1.3kWh slightly smaller number, estimated at around 1kWh.

About EV (all electric mode) can travel a distance, Nissan said, "and the Prius to the same extent," although smaller capacity, but for longer distance traveled, and increase the battery SOC (state of charge) the use of. EV driving range because of the battery charge status and whether or not the same acceleration and deceleration while the Prius is 2-3 km.

Nissan main electric cars

However, Toyota and Honda have a head start in the hybrid market, the current emphasis on the development of Nissan electric car market. Nissan also announced this month, an electric car test car. Front-wheel drive test car is the engine room is equipped with a power of 80 kilowatts of newly developed motor and inverter, based on the existing "Cube" model manufacturing. To not reduce the interior space, AutomotiveEnergySupply (AESC) of the laminated lithium-ion rechargeable battery located under the floor.

Nissan is scheduled for 2010 in Japan and North America market electric vehicles in 2012, extended to the whole world. Scheduled for 2010 did not follow the listing of the existing body of electric vehicles, electric vehicles instead of using specially designed for the new models.

NB battery module factory batteries news

4th quarter, according to market rumors that the battery core supply and demand is expected to become the global balance, battery core prices probably will decline, Taiwan notebook (NB) cell module plant is that the current balance between supply and demand on the battery core is also too early to demand the second half of view estimated battery cells are still in short supply conditions, the overall supply is still insufficient to meet demand, estimated to have to wait until 2009 to open up new capacity is completed one after another, the overall battery core supply and a chance to reach equilibrium.

Manufacturers that Q4 core of the international battery manufacturers of the new capacity out one after another, coupled with the mainland battery core supply of plant parts make up the gap, making the core out of the battery slightly eased the situation, perhaps the battery core prices moderated slightly promote NB cell module price down, but the estimate of the overall gross margin impact Buzhi Yu too, with the battery core supply increases, benefit from volume growth, economies of scale will make up for falling prices affect the site, NB battery module for the second half of the industry outlook is promising.

S & P said the new technology, see Q3 current battery core supply is out of stock, despite the season 4 would be more relieved, estimated the overall supply is still insufficient, needed to 2009, the overall battery core supply and demand will tend towards equilibrium, 4 quarter to increase the supply of main reasons in addition to South Korea's LG Chemical Plant (LGC) capacity gradually return, and some of mainland China factory supply battery cells to fill the gap, the battery module is conducive to NB in Q4 shipments continued to grow, but not enough overall business required.

Company said, because the battery core is supply and demand imbalance, both in order to satisfy the already battered Liang, let alone new customers and new Yingyongcengmian, such as portable devices outside the Chu NB, Gong Ji Moreover Bulun battery cells or not enough, the most the main thing is to observe the ability of the company's orders, if the ability to get orders strong enough, the battery core supply better, create more traffic, In addition, the battery core supply growth is also conducive to cost control, the new Price that is a good thing, observe the 4th quarter of the current orders is still quite good, but the battery core supply is inadequate, for the second half of its growth is still very confident.

Shunda technology also understand that the 4th quarter of the battery core supply and demand would still not balance out the short set. Company said the new production after another out, 4 quarter of the battery core supply and demand gap is expected to be more relieved, but still short of the demand is not enough orders, because the second half of NB industry growth, but it seems quite good, seem to affect the U.S. economy not, of course, NB for the overall market in Q4 sales or further observation, but the present circumstances, it had enough battery core supply, if the sales were above expectations, the core will only missing battery.

Companies that worry about the battery core supply of the outside world increase, will cause the price drop, but even if the price reduction will not increase too much, of course, to cell price cuts, NB battery module will be followed by lower, but estimates for the gross margin impact will not be too Big Moreover, the battery core supply increases, NB battery module shipments increased and then conducive to economies of scale, is expected to offset the gross margin decline caused some price cuts, so for the second half of the overall view of NB cell module industry is optimistic about the economy, growth can be expected.
