Distributed Lithium Batteries To Test The Remote Control Management System Design And Implementation

Lithium battery is a hot topic in the power cell area, due to its high workingvoltage, high capacity, high energy capabilities, long cycle life, zero memory effect,light and green. Currently, the requirement of lithium battery is growing as fast as30%annually. So, it brings out the higher demand for the quality of Lithium battery.Lithium battery detection is the last and the most important logistics link in the wholeBattery Production. It relates to the batter quality and whether it is up to standard.Monomer batteries should be used as group, since the single one can not meet thedemand of electric vehicle. While the uniformity of power influences the effective ofLithium battery series. It is well known that the rest of the battery power is veryimportant for the driver, during the operation of electric vehicle, which limites driver’swork directly. Thus, real-time judgment is quite important for stage of charge.In the lithium battery detection system, the control unit plays as a role for datacollection and battery charge and discharge operation. While the whole processrealized by the host computer. It accomplishes the lithium battery into detection systemof the PC software and the battery of intelligent sorting work by MFC in this article.Meanwhile, it puts forward a kind of test methods for SOC(state of charge) combinedwith Matlab. Main Content As Follows:(1)According to production requirement, the host computer does modularprogramming, including control module, data processing module, work editing module,battery separation step with group module, and battery SOC estimation modules,considering the energy recovery,(2)The voltage-current curve during process of charging and discharging reflectsthe characteristics of the battery. So, it does an intelligent sorting by selceting thisvoltage-current curve and following FCM(Fuzzy C-means) algorithm. As a result, ithas been greatly improved in storage and stability of battery.(3)It can not calculate the battery state of charge (SOC) when it’s working by theadditional ampere-houe integration. The SOC will be far to correct value, if it can notmeasure the battery current and coulomb efficiency accurately. It estimates the SOC by improved method in this article. It brings out an improved the ampere-houe integration.After considering the influence factor, it brings out a new improved ampere-houeintegration. By the test, this new method provides a good standard for battery chargingwhen working.
