School of architectural engineering, Northeast Dianli University, Jilin, Jilin 1320121; 3.. Tianjin Lantian hi tech power supply Co., Ltd., Tianjin 3100381, China) pick To be: Based on the existing lithium-ion battery manufacturing level, there is a certain difference in monomer batteries, in order to avoid individual monomer overcharge, excessive release Battery failure caused by the average level of the performance close to the single battery, battery to achieve balance control between each monomer, describes the balance control method, cell circuit design and implementation steps, and the lithium ion battery balance charging test, the results show that this method can effectively compensate for the battery inconsistency. Key words: lithium-ion battery pack; equalization control; battery management; document identification code; A; CLC number: T M 9106 Lithium ion batteries have been widely used in portable electronic products (such as mobile phones, laptops, camcorders) and power supplies for electric vehicles. The power supply is usually composed of a series of individual batteries in series to meet the voltage and power requirements of the equipment. In actual use, the capacity of the battery can only reach the weakest capacity due to the difference between the individual cells. In series battery, although the current thro
