Abstract
A controller for detecting voltages of battery cells in a battery pack includes converters coupled to the battery cells and switching units. An anode of each battery cell is coupled to a respective converter through a respective first path, and a cathode of each battery cell is coupled to the respective converter through a respective second path. The switching units are coupled between the battery cells and the converters. The converters are coupled to anodes of the battery cells through the switching units. When a switching unit corresponding to a battery cell is turned on, an anode of the battery cell provides an operating current and a sampling current through a respective first path to a respective converter, and the operating current flows from the anode of the battery cell through the respective converter to ground.
