动力电池组特性分析与均衡管理（Characteristic analysis and equalization management of power battery） Characteristic analysis and equalization management of power battery Abstract: the battery has additional features different from the single battery, the power battery based on the design and manufacture level, the performance difference between the monomers exists in the whole life cycle, in order to avoid the monomer due to overcharge and overdischarge which result in invalidation, the average level of the function and performance of battery the single reached or close to the body, to achieve the balance between the control and management of battery monomer. Is the only way which must be passed battery equalization management is an advanced battery technology to use, based on the latest research achievements of power battery, power electronic electrochemical model and computer control technology, innovative design. Keywords: lithium-ion batteries, power batteries, storage batteries, battery usage, equalization control, battery management Preface Is the electric car car of the future is a combination of electric source, motor and three vehicle technology, electric source is the core component of the electric car has formed a power lithium ion battery and its special material development boom. As a new type of power technology, lithium batteries must be in series to achieve required voltage in use, the monomer on the uneven performance is not entirely due to the battery production technology, from the film began to be finished after process, even if each procedure has strict testing procedures, so that each battery voltage, internal resistance, capacity, use after a period of time, will also have the difference the technical problems of lithium batteries is imminent, and must be solved as soon as possible. The service life of power battery is affected by many factors, if half the battery life is lower than the average life of monomer, can be inferred are caused by the improper use o
