CA 2115843

An energy management load panel arrangement includes a load panel enclosure (10) having a plurality of circuit breakers (20), each of which opens and closes in response to a control signal so as to interrupt an associated current path. A microcomputer (120) generates the control signals to control the position of the circuit breakers (20) and their associated current paths, and a volatile memory circuit, for example, RAM (126), stores time-event data which is used to indicate when the control signals should be generated. A charged electronic double-layered capacitor (144) is coupled to the volatile memory so that, in the event of a power outage, operating power is provided to the volatile memory for extended periods of time. A real time clock circuit (138) is used to track the time, and the charged electronic double-layered capacitor is coupled to the real time clock circuit (138) so that it also continues to operate during a power outage.

Un panneau indicateur de charge destiné à la gestion d'énergie comporte une enceinte (10) dotée de plusieurs disjoncteurs (20) dont chacun s'ouvre et se ferme en réaction à un signal de commande afin d'interrompre le trajet d'un courant associé. Un micro-ordinateur (120) engendre des signaux de commande régissant l'état de ces disjoncteurs (20) et de leurs trajets de courant associés et un circuit de mémoire volatile, une RAM (126) par exemple, enregistre les données de chronologie et d'événements utilisées pour indiquer quand il convient d'engendrer ces signaux de commande. Un condensateur électronique chargé à double couche (144) est couplé à la mémoire volatile pour qu'en cas de panne de courant, cette mémoire volatile reçoive son énergie de fonctionnement sur une période prolongée. Un circuit d'horloge à heure réelle (138) permet de suivre la chronologie et le condensateur électronique chargé à double couche est raccordé à ce circuit (138) de façon que ce dernier puisse aussi continuer à fonctionner pendant une panne de courant.
