The intelligence of rechargeable battery tests systematic research and design

ABSTRACT: On the basis of new-type PIC one-chip computer , mix with the high-accuracy measurement control system , excessive pressure , pass to flow , shorting out to protect the circuit etc., can work out the intelligence of the rechargeable battery and test the system. Focus on around with system intelligent , dependability , security , extensive one confirm the systematic scheme, Have designed the systematic operation principle block diagram , unit circuit and relevant systems soft ware designed for the hardware. Such characteristics as this system has high performance , low cost , safe and reliable. Through testing, the system is right but the test result of every performance index of the rechargeable battery is accurate, it is novel to test the scheme , benefit the fast sorting of the electric core and finished product battery of battery manufacturer , guarantee the quality of the products, reduce the cost and service expenses , can differentiate the quality of the battery and every performance index of mastering battery , have very important meaning to quality control and after-sale service.
