By using Li-ion battery as storage battery, single 12V battery package assembles by six Li-ion which is series and parallel. Between each battery packages can connect together, and provide power source of 12V magnification. In addition, each battery packages has the function of life monitoring. We also plan completely the function of battery’s capacity management, charging process measurement, and scheduling of charging and supplying. In this power system, life monitoring can be established based on the method of cumulative error and scheduling of charging and supplying to complete dynamic measurement. Then using mixed type of residual power measurement which consisting of the method of open circuit voltage and the method of Coulomb Counting to measure capacity. Otherwise, the power system can extend battery life by discharging balance and monitoring temperature and current, and prevent it from dangerous state. When the power system is charging, it is managed by process measurement according to voltage of Li-ion batteries. Besides, it can be protected when overcharging and reverse charge and ensure safety of batteries. Depending on various voltage requirement, the power system can satisfied by using different configuration. Therefore, the author designs experiments of life monitoring, power supply management, charge process management, and scheduling of charging to confirm the feasibility of this power system. Finally, we confirm result of experiments are same as anticipation.
