摘要:
The invention relates to an electrical apparatus (1), including: a circuit breaker (5) having an breaking capacity PdC and a breaking current Is; a DC voltage source including two batteries (3) connected in parallel, connected in series with the circuit breaker, the sum of the short-circuit currents of the batteries being greater than the breaking capacity, each battery comprising: a first branch including storage batteries (300) and a switch (310) connected in series; a second branch connected in parallel with the first branch and including a free-wheeling diode (340); an ammeter (320) measuring the output current; and a control circuit (330) configured to detect a short-circuit. The control circuits simultaneously keep the majority of said switches (310) open and close one switch in order to apply a current passing through the circuit breaker (5) which is higher than the breaking current Is and lower than the breaking capacity.

摘要:
Method of detecting an overcharging of an accumulator (11) of a battery (10) comprising a set of parallel branches (B1,..., BN) each comprising accumulators (11) disposed in series, said method being characterized in that it comprises the following steps: (i) collecting the measurements of the currents flowing in the branches of the battery; (ii) identifying at least one discrepancy of current in a branch with respect to at least one other branch as a function of the measurements of current collected; (iii) determining a level of state of charge of said branch; and (iv) detecting an overcharging of an accumulator in said branch as a function of at least said discrepancy of current identified and of the level of state of charge determined.
