Abstract:
1. A monitoring system for a battery having a plurality of accumulators, the system comprising: means for measuring the voltage at the terminals of each accumulator; means for measuring the temperature of the battery; means for measuring the current flowing through the battery; means for calculating a voltage difference between a maximum voltage measured on the terminals of one of the accumulators and a minimum voltage measured on the terminals of one of the accumulators; means for comparing the voltage difference with at least one threshold value depending on the measured temperature and current; and means reporting an error if the voltage difference is greater than or equal to said at least one threshold value, wherein the voltage difference (ΔV) is compared with a threshold value (ΔVs wherein p is the number of parallel branches of accumulators of the battery, ΔR Ibat is the current flowing through the battery.
