    摘要: Voltage balancing in multi-cell battery packs is improved by estimating instantaneous voltages on the cells. In accordance with one embodiment, an apparatus for reading voltages from multiple voltage sources includes a first multiplexer coupled to multiple voltage sources and a controller. The controller is programmed to output from the first multiplexer a sequential pair of voltages read from each of the multiple voltage sources. The multiple sequential pairs of voltages all have a common midpoint in time. The multiple sequential pairs of voltages are all read within a small time window, such as 100 microseconds. In one embodiment, the multiple voltage sources are Li-ion or other high-voltage cells, though other types of cells can also be used.
