| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 105 === Variability between batteries is caused by the manufacturing process,
which will increase by cycle life. It is very dangerous to ignore battery
cell’s degradation effect. Severe damage will happen to batteries and threat
user’s personal safety.
Compare to other charge balancing method, applying switching
power supply as charge balancing method has some advantages, such as
high balancing power, low balancing time and easy to expand. A
bi-directional flyback converter is applied as experimental platform for
charge equalization system. Digital control units and communication
network are also inserted in charge equalization system. Digital control
units will exchange data over communication network and generate a
control command to control bi-directional flyback converter. In the other
word, charge will be transferred between batteries by giving the control
command to bi-directional flyback converter and batteries will be
balanced.
