Title: Accumulator chargeing circuit with voltage sensitive switching - to eliminate excessive charging and compensate for leakage currents uses voltage divider
IPC: H02J7/00
Filed: 1975-11-07
Abstract: The circuit is arranged to interrupt the current between the charging supply and the accumulator when the voltage of the latter has risen to a predetermined value, and to switch the current on again if the accumulator voltage falls below a second, lower, preset value.
