In the last few years, the domestic economy energy cell market have already been capture by the ocean product, not a few cellular phone cells of person usage are all the that day is originally, inlet from the United States of.The hydrogen of nickel, the cell of lithium ion is the information to pay the pillar industry for ages, the economy energy, the decrease pollution of the environment, the use is more and more extensive, the need is more and more big.Win relevant personage in the section hospital call that the main production material of the nickel hydrogen cell is the metal nickel and sparse soil metals, but the by luck sparse soil of our country keeps the quantity very abundant, for produce this kind of economy energy the cell provides the foundation of matter.In 863 plans of our country, in the physics of the section hospital open the exhibition foundation research to the lithium ion, the nickel hydrogen cell, at the same time in the finance and capitals on the market the seek cooperates the colleague, turning for the research industry, the market turns to lay the foundation.A machine system not only have the extensive use in the general industry application, at household appliance in also very in common use.The useful life and a circulating usage times and charges of the cellular phone cell support the process and use the circumstance closely related.A good charger not only the ability is filled with quantity of electricity in the in a short time, but also can also can rise the certain function of maintenance to the cell, repair because of use not appropriate but the memory effect that result in, since the capacity droop( the cell activity decline) phenomemon。Keyword: Intelligence Mvcu Cell Charger
