<p>A series of accumulator cells is monitored by means of special measurement processors (s), one measurement processor to each cell. Each measurement processor (s) comprises a number of sensors for measuring parameters like temperature, acid density, acid level and pole voltage, as well as a microprocessor. The microprocessor reads measurement values and supplies these values to a common data bus (d). Each measurement processor (s) takes its power feed current from the accumulator cell to which it belongs.</p> |
