Summary: | Electric vehicles (EVs) are being developed and considered as the future
transportation to reduce emission of toxic gas, cost and weight. The battery pack is
one of the main crucial parts of the electric vehicle. The power optimization of the
battery pack has been maintained by developing a two phase evaporative thermal
management system which operation has been controlled by using a wireless battery
management system. A large number of individual cells in a battery pack have many
wire terminations that are liable for safety failure. To reduce the wiring problem, a
wireless battery management system based on ZigBee communication protocol and
point-to-point wireless topology has been presented. Microcontrollers and wireless
modules are employed to process the information from several sensors (voltage,
temperature and SOC) and transmit to the display devices respectively. The WBMS
multistage charge balancing system offering more effective and efficient responses
for several numbers of series connected battery cells. The concept of double tier
switched capacitor converter and resonant switched capacitor converter is used for
reducing the charge balancing time of the cells. The balancing result for 2 cells and 16
cells are improved by 15.12% and 25.3% respectively. The balancing results are
poised to become better when the battery cells are increased. |
