MEASUREMENT DEVICE AND METHOD FOR SORTING USED BATTERIES AND ACCUMULATORS

摘要

2079219 9115036 PCTABS00007 A device and method for sorting batteries of used batteries and accumulators on the basis of their chemical constitution. The measurement device is based on the analysis of the inductive effect produced by the substances which are contained in the battery or accumulator, and whose ferromagnetic properties differ according to their chemical constitution. The mesasurement method in which this device is used is based on the consecutive application to the excitation circuit of at least two different voltage amplitudes at the same frequency or two different frequencies at the same voltage amplitude.
