An undervoltage recovery pulse network (500) and method used with a lithium ion battery system (400) for providing a initiation voltage to a battery controller (503) which has been operationally disabled due to an event associated with the lithium ion battery system (400). The undervoltage recovery pulse network (500) includes a switch (523) for detecting a first voltage applied to a data terminal (537) by a charging system. A coupler (525) is used for supplying a second voltage from a charging terminal (535) to the battery controller (503) to enable the battery controller from its disabled state. The battery controller (503) then connects the voltage potential of a cell (501) to the charging terminal (535) for detection by a charging system. This allows the charging system to detect an attached battery so it may apply a charging voltage to charging terminal (535).
