Abstract
A monitoring system () monitors voltage of a stack of batteries (.) Each battery has a plurality of cells (). A monitoring unit () is associated with each battery and measures voltage across a selected cell. A first monitoring unit and a second monitoring unit measure the same cell, e.g. cell Cn,of batteryThe first and second measurements are used to calculate a correction factor which can be used to correct a set of measurements made by one of the monitoring units (). The monitoring units () are arranged in a chain, with adjacent units in the chain being connected by a communication interface in which data is transmitted as signaling voltage levels between interface units. The interface units () of a pair of monitoring units () use the same signaling voltage levels.
