Charging device for a group of batteries, especially of buffer batteries fed by a limited power supply.

摘要

The charging device comprises a charger (Ch) and batteries (B1 to Bn) connected in parallel with an end-use circuit (1) via diodes (D, D1 to Dn). Each battery is in series with a shunt (Sh) with which is associated a device (4) for monitoring the state of charge, which is connected to an input (A1 to An) of a sequencer (S). The sequencer has a control output (Ao) connected to the charger and controls the thyristors of a rectifying bridge of the charger. The sequencer comprises contacts (C1 to Cn) each inserted between a polarity of the charger and a same-sign polarity of a battery in order to charge the said battery across the shunt with which it is associated. <IMAGE>
