Speaking of the battery supply, the consumer hoped that the portable electronic products can by "the lower electric quantity execution multi-purpose", simultaneously, the numerous manufactured products also start to transfer use the battery power supply. Digital signal processor (DSP) commonly used in request high performance application domain, thus causes the clock running rate to promote unceasingly. ... -
Based on SP6648 new miner’s lamp design
Friday, April 17th, 2009 at 23:00 | No commentsCategories: Power SupplyShort Content: The miner's lamp is the coal mine miner's necessary mine shaft illumination lamps and lanterns, plays the very vital role in the miner downhole operation, is called "miner's eye". The miner's lamp belongs to the special explosion-proof product, its safety performance and the quality and the coal mine safety production are closely linked. In recent years, the gas coal dust explosion accident which induced as a result of the miner's lamp use ill management as well as the power ... -
Based on “flies the electric capacity” the technical power lithium ion battery protective system
Thursday, April 2nd, 2009 at 19:08 | No commentsCategories: Power SupplyShort Content: 0 introductions In recent years, more and more lithium ion battery factory joined to the power lithium ion battery's research and development troop, although the power lithium ion battery was opposite in the nickel hydrogen, the plumbous acid as well as the nickel cadmium cell in compared to the energy, the volume, the life, environment-protective and so on various aspects has the incomparable superiority, moreover its scale application also ultimately, but aspect and so on battery's cost, security ... -
Battery bidirectional lossless balanced charging and discharging module design
Monday, February 23rd, 2009 at 04:02 | No commentsCategories: Power SupplyShort Content: Abstract: Because the series battery charges the time not to be imbalanced, causes the battery cycle life to reduce, the equalizing charge has become in the series battery charge technology the important consideration factor. Charges the time for the improvement series battery not to be balanced, should guarantee that in the battery all battery's voltage occupies the identical horizontal position. This article designs one kind to control bidirectional lossless balanced sufficient, the electric discharge module with the monolithic integrated circuit, ... -
Realizes the intelligent fast battery charger design using GM6801
Thursday, February 19th, 2009 at 00:02 | No commentsCategories: Power SupplyShort Content: At present, the application quite widespread rapid charge rate management chip basically has two types. One kind is a monolithic integrated circuit, another kind is the rapid charge rate management specific IC. Chengdu country leaps the micro electron Limited company success to develop section of nickel hydrogen/nickel cadmium cell rapid charge rate intelligence management chip - - GM6801. This chip's exterior base pin control function is programmable, does not need the exterior controller support, causes the charging-up examination control ... -
Electric automobile battery management system management system’s multi-channel voltage gathering circuit design
Saturday, February 7th, 2009 at 02:53 | No commentsCategories: Power SupplyTags: A/D, Battery, electric automobile, management system management system, voltage gathering electric circuitShort Content: Abstract: This article introduced in the battery management system management system one kind of novel multi-channel voltage gathering electric circuit, this electric circuit applies in gathering battery monomer voltage number quite many situations, can obviously reduce the circuit wafer the area and reduces the cost, simultaneously is not big to the measuring accuracy influence. In view of the electric circuit some questions which appears in the software simulation and the practical application, this article analyzes its reason, and improves. ... -
Correctly series connected and is parallel - en.51rd.net the battery
Monday, January 19th, 2009 at 03:35 | No commentsCategories: Power SupplyTags: BatteryShort Content: Series connected and is parallel the use the battery, this sounds to be probably very simple, but, follows some simple rules, may avoid the nonessential question. Is connects in the battery many batteries, obtains working voltage which needs. What if needs is a higher capacity and a bigger electric current, that should be parallel the battery. In addition has some batteries, unifies series connected and the parallel these two methods. A laptop computer's battery has the possibility is connects four ... -
New style independent type linear lithium ion battery charger
Sunday, January 18th, 2009 at 12:35 | No commentsCategories: Power SupplyShort Content: The rechargeable battery battery is used for frequently for such as the digital camera, PDA, the mobile phone and the MP3 broadcast machine and so on portable equipment power supply. Exchanges the adapter is the most commonly used charging source, but, more and more applications start to turn on the available USB power source. LTC4061 and LTC4062 are to use above two kind of power source's any one kind to give the single-node lithium ion battery charge specially to design. ... -
22 NiCd/NiMH battery charge controller
Monday, January 5th, 2009 at 00:14 | No commentsCategories: Power SupplyTags: BatteryShort Content: The battery which constitutes by 22 NiCd/NiMH batteries wraps in the practical application to be quite common, this kind of battery package of request low end, light-sized, simple Yi Yong battery charger. This article introduced the charge plan is one kind of low cost charge controller which consumes in a section of standard 16 NiCd/NiMH battery charger's foundation modifies, as shown in Figure 1. Figure 1 MAX712 (or MAX713) is aims at 1 to 16 NiCd/NiMH battery design battery charger, ... -
Lithium ion battery charger LTC4062 and application
Friday, January 2nd, 2009 at 19:45 | No commentsCategories: Power SupplyTags: BatteryShort Content: In recent years, the handset, the digital camera, MP3 and so on portable product was small to the volume, thickness was thin, the weight light direction developed, the new product weeded through the old to bring forth the new, the output also increased suddenly. In these new products uses the lithium ion all (or polymer) the battery, because it can slightly satisfy, thin, the light request, and the capacity is big, can lengthen the time-gap which two times charge. Meanwhile, ...
