Portable Lithium Battery Cell Voltage Online Initiative Balancing System

A portable lithium battery cell voltage line active balancing system was designed and implemented, aiming for the monomer equilibrium problems of lithium batteries during charge and discharge period, based on real-time high-precision detection and rapid parametric feedback regulation principles. The system was used in the process of the battery pack by detecting real-time acquisition voltage, current, temperature and other parameters of the battery. The system achieved every single battery＇s overcharge, charge less, over discharge, over-temperature condition between monomers initiative balance by charging monomer from the total voltage. The overall system size is 160＂60＂105mm, with in-line battery equalization adjustment. Experimental results showed that the system could achieve the 9 monomer real-time proactive equilibrium, the balanced response time of peak current was around 300s, to adjust the monomers＇unbalance less than 5% voltage, reaching real-time on-site battery active balance applications thereby ensuring the energy supply safety target.
