This battery box is equipped with Sony CD Walkman models is the D-NE1, D-NE9, D-EJ985 and D-EJ885. This four CD players in October 2002 to April this year, sales during the period. The recall of 330,000 battery boxes are sold in Japan.
Liu: First, high efficiency. Fuel cell power generation is not between the energy loss aspect. Thermal or nuclear power, only 40% of maximum efficiency, and fuel cell power generation efficiency is generally 40% ~ 60%, emissions of heat can also be used for the second generation, the utilization efficiency of up to 70% ~ 80%.

My
overall view, 2010 for China's SMEs, Ye Hao, Zhongshan University,
dell INSPIRON 2600 battery either enterprises or are a chance. First,
the state's policy to support rural and small towns for development. I
think we all see it. Ye Hao led the state's financial arrangements,
the state capital will increase the flow to rural areas and small
towns, thereby facilitating the goods, logistics flow to rural and
small towns.
Second, the flow of capital to the central and
western cities, which is an indisputable fact. Can be seen from a few
years ago, the central and western development strategy, the real into
the large-scale development phase, the timing is right. Eastern
economic development, industrial structure upgrade, companies will
take the initiative to the central and eastern part of the transfer.
This trend will bring the Midwest to accelerate the urbanization
process will give enterprises a very good investment opportunities.

Thirdly, since the adjustment of industrial structure brought about by capital flows. This national policy has been reflected out. The central authorities have issued a plan to revitalize the local economy, a natural development from the perspective of Chinese industry, but also to the upgrade stage. Eliminate backward and excess capacity, long-term development dell INSPIRON 2650 battery of enterprises must be beneficial. I say 2010 is China's opportunity as well as opportunities for Chinese enterprises.
The development of lithium-ion battery technology, security issues must be addressed
With lithium-ion battery technology in materials and design improvements and development, its use has expanded the parameters of the corresponding index is rising. A certain extent, security is and is inversely proportional to the weight of lithium-ion battery, so with the emergence of large-scale power lithium battery, the security index followed by the international attention.
The development of lithium-ion battery technology, the need to address security issues, laptop keyboardlithium-ion battery in normal use conditions are usually safe,ThinkPad R50 the industry is mainly concerned with the misuse or abuse of how to ensure safety. Battery in the abuse of process because of the thermal reaction within the battery can not be spread in time lead to thermal runaway will occur leak, rupture, fire and so on.
To ensure that the electrochemical lithium-ion battery and physical security, domestic and international authoritative organizations have developed a variety of lithium-ion battery safety testing standards.
General safety test items are generally divided into four categories: AC adapter laptop battery
A, electrical test: over charge, over discharge, external short circuit, forced discharge, etc.;
B, mechanical testing: the impact of acupuncture, compression, vibration, shock, drop, etc.;
C, thermal test: temperature cycling, microwave heating, sand bath, combustion tests;
D, environmental testing: a high degree of simulation, antimicrobial resistance testing.
Here are some of the security properties about the most common test methods.
November 19, Sony said it will recall globally for 550,000 of the external CD Walkman battery box,Sony PCGA-BP2V Battery, Sony PCGA-BP4V Battery, Sony PCGA-BP71 Battery, because the battery connectors together the existence of soft-line failure, may lead to the battery box temperature and some melting.
Sony spokesman said that at present have received the report of the accident. A portable CD player Walkman users of the nylon bag was burned out the battery box.
Sony said that it could not recall the battery box to provide the estimated total cost of this issue is currently being evaluated.
The spokesman said that such a battery box is in Indonesia, Sony PCGA-BP2S Battery, Sony PCGA-BP2T Battery, Sony PCGA-BP2V Battery, a manufacturer's accessories.Sony PCGA-BP2V Battery, This player is not defective machine itself.
