Abstract
A power supply system using an energy storage cell includes at least one lithium cell module; a voltage balance device, received and built in the lithium cell module, for performing voltage balance; and a cell module voltage monitoring device, disposed between a load and the lithium cell module, for monitoring and controlling working voltage ranges of all the lithium cell modules. The voltage balance device built in each lithium cell module performs charging correction on a lithium cell unit in which a capacitance difference is caused by a fabrication process or caused subsequently, to prevent overcharge damage of the lithium cell unit caused by the capacitance difference. The cell module voltage monitoring device is provided on an external line, and only a correct total charge voltage needs to be provided to charge the lithium cell module.
