BFGS-9512 batteries formation and grading test system is designed for Lithium polymer batteries formation and grading test system. Advanced computer data centralize collection and control software (network connectivity and SQL database), with itself keyboard and Large LCD with Chinese characters (full Chinese man-machine conversation interface),digital current and voltage automatic calibration. This system is the ideal choose for large-scale battery factories. The system is composed of upper, middle and lower computer .Above machine is composed of a computer and controlled software. Middle machine compose of Single Chip Microcomputer and screen. Each middle machine controls 8 or 23 low machine . Low machine is deviced by model. Each Low machine composes of independently 16 battery channel. One middle machine and 8 or 23 Low machine compose one battery case. Each battery case can sork not only in middle machine control but also in above machine. 1. Adopting network connectivity and SQL database, concentrate control several machine (join 255 maximum; 65280 points.) 1.Absolute MPU for each channel, single-point control with quick-rate and high-accuracy 2.Independent constant-current source and constant-voltage source 3.Undisturbed switch between constant-current and constant-voltage 4.Automatically correct the digitized errors with high speed and accuracy 5.Large LCD with Chinese characters, easy operation 6.Combined with computer to integration control, data integrated analysis, statistic, report, print, etc. 7．Charge flat-roof grade and curve grade; 8.Module construction, high reliability, each module provides 16 independent channels, this function is convenient for the system’s maintenance 9.Industrial programming design, all the operation carry out automatically according to the designed working steps 10.High accuracy, fit with small current grade(〈10mA〉
