ABSTRACT

Lithium-ion (Li-ion) batteries are widely used in many places because of their high energy density, long life, and low self-discharge rate. However, when the performance of the Li-ion batteries deteriorates, the battery capacity is shortened, resulting in an increase in the charging frequency.
Therefore, in this research a low power Smart Battery Management System (SBMS) will be designed, which can optimize the battery usage and on the same time extend the lifetime of battery. This will be realized by pulse
charging and discharging (in the range of 10 Hz - 1 kHz) the battery. The SBMS will be a high reliability, low-loss balancing system based on wireless communications. Compared with the traditional Battery Management System
(BMS), SBMS has the advantages of high efficiency, low switching frequency and simple topology. Under the premise of a certain battery cell performance, the power utilization and reliability should be improved as much as possible. In addition´╝îthe system uses wireless transmission and cloud computing technology to enhance digital processing functions and
signal transmission speed. Therefore, the system carry out complex calculation faster and increase the reliability of the system.
