Abstract
(EN)
This battery polarity determination circuit is provided with: a battery housing unit 2 including a first contact T1 and a second contact T2 which touch the respective electrode terminals of a battery BAT; a control device 3 connected through a resistor R to a voltage lead-out point P1 to which the voltage of the battery BAT is led out and determining a polarity of the battery BAT; a connection switching circuit 4 capable of switching between a first connection state and a second connection state; and a diode D having a cathode connected to a voltage reading point P2 to which the resistor R and the control device 3 are connected and an anode connected to the ground. The control device 3 determines the polarity of the battery BAT on the basis of the voltage VP2 at the voltage reading point P2, which corresponds to the connection state of the connection switching circuit 4. The forward voltage VF of the diode D is set so that the voltage VP2 at the voltage reading point P2 becomes greater than or equal to the lower-limit value VMIN of the absolute maximum rating of the control device 3.

La présente invention concerne un circuit de détermination de polarité de batterie comprenant : une unité de logement de batterie 2 comprenant un premier contact T1 et un second contact T2 qui touchent les bornes d'électrode respectives d'une batterie BAT ; un dispositif de commande 3 connecté par l'intermédiaire d'une résistance R à un point de sortie de tension P1 au niveau duquel la tension de la batterie BAT est sortie et déterminant une polarité de la batterie BAT ; un circuit de commutation de connexion 4 apte à commuter entre un premier état de connexion et un second état de connexion ; et une diode D ayant une cathode connectée à un point de lecture de tension P2 auquel la résistance R et le dispositif de commande 3 sont connectés et une anode connectée à la masse. Le dispositif de commande 3 détermine la polarité de la batterie BAT sur la base de la tension VP2 au point de lecture de tension P2, qui correspond à l'état de connexion du circuit de commutation de connexion 4. La tension directe VF de la diode D est réglée de telle sorte que la tension VP2 au point de lecture de tension P2 devient supérieure ou égale à la valeur limite inférieure VMIN du niveau maximale absolu du dispositif de commande 3.
