Smart Battery Charge And Discharge Management System

The trait of news accessing require the capacity of battery where and when must be ensured, and it can be management conveniently. Because three kinds of chemistry characteristics refresh the battery to exist in the customer currently at the same time, the lithium ion battery , Nicd and NIMH batteries refresh the make type dissimilarity, the charger of their its can't carry on refresh each other, otherwise will result in battery can't be full charged , even battery drive damage or take place the danger. Therefore, the compatible problem of charger and battery is an important topic. The news departments to the battery refresh management and useing is a bother matter, make use of the computer to refresh to carry on the management that gathers the spread type to the battery that can let them from numerous and complicated refresh to manage the medium liberation to come out complicatedly. This text puts forward and resolves the follows problem:Precision display remain capacity of battery:Regardless battery just at refresh and discharge or get empty to carry, through the LCD screens and can indicate remain capacity of battery , overcoming the shortcoming that indicate only percentage of capacity by cent of regularity in the passed, according to dissimilarity of the electric appliances , it can accurate show remain time of useing, overcoming the shortcoming that common battery show difference because the condition of getting empty to carry or carry , more benefit in usage;Parameter of battery dynamic showing :showing dynamicly the remain capacity of battery, battery temperature, charging current, charging voltage and the chemistry characteristic, accurate circulation number of times that battery have been used already... etc., more easy to maintenance;For solving the compatible of battery with different characteristics andcharger, researched to manufacture the intelligence charger in this text, it can communicate battery with different access and use the correspond way to charge different chemistry characteristic battery, and control intelli-genclly charging and discharging, it can also communicate through a serial to computer, convenience to the management of battery and it charging.We set a own serial number for each intelligence battery , so we can collect and save every time information of intelligence battery charging and discharging through a collect station, so we make computer analysis these information of charging and discharging , making an curve that each battery charging capacity attenuate, thus getting the usage condition of smart battery. According to these conditions information, we can make a judgment to the life of the battery, eliminating the battery that can't be requested, avoiding the shortcoming that we only use circulation number of times to decide the life of the battery .
