Accumulator charge state monitoring device has a complementary current source to maintain voltage stability and a measurement resistance across which a voltage drop is measured

摘要

Manner for checking the charge state of an accumulator (16) in which a circuit is provided with a complementary current source (18) and the voltage drop across a measurement resistance (R11) is measured. The direct current of the current source only circulates in the accumulator circuit if the absence of an accumulator charging current. An independent claim is made for an arrangement for checking the charge state of a battery comprising a complementary current source with a stabilizing voltage, a measurement resistance and an indicator (15). The latter is connected in parallel with the indicator. Between the generator rectifier (A) and the accumulator is a thyristor (3).
