Effects of the measuring voltages circuit on Li-ion batteries piles
Xinhua Jiang, Feng Yi, Jingying Xie · Battery Bimonthly · 2005
The measuring voltage circuit in Li-ion batteries piles was analyzed and designed.It was experimentally revealed that the difference in performance among the batteries increased with the cycles for Li-ion battery by using ten Li-ion batteries piles.The cyclic life of Li-ion batteries piles was studied by increasing input impedance. The results showed that the effects on the consistency of batteries series should be considered, when designing measuring circuit. The methods that mitigated the (effect) of measuring voltages circuit on Li-ion batteries piles were considered.
