A relay control device according to the present invention is used for a relay comprising: a contact connected between a positive electrode of a battery and a load; and a coil connected between a relay power terminal and ground and moving the contact to a closed position during application of an electric current. The relay control device comprises: a coil control switch turned on in response to a first switching signal, which is a signal having a voltage level greater than or equal to a first threshold voltage in response to a relay on-command; and a relay holding circuit configured to store emergency power using power supplied from the battery.
Un dispositif de commande de relais selon la présente invention est utilisé pour un relais comprenant : un contact connecté entre une électrode positive d'une batterie et une charge; et une bobine connectée entre une borne d'énergie de relais et la masse et faisant passer le contact vers une position fermée pendant l'application d'un courant électrique. Le dispositif de commande de relais comprend : un commutateur de commande de bobine mis en marche en réponse à un premier signal de commutation, qui est un signal ayant un niveau de tension supérieur ou égal à une première tension de seuil en réponse à une demande sur commande de relais; et un circuit de maintien de relais configuré pour stocker une énergie d'urgence à l'aide de l'énergie fournie par la batterie.
