Abstract
(EN)
This protection circuit 120 of a power storage element comprises: a cut-off switch 55A for interrupting electric current in the power storage element; a drive circuit 150A for driving the cut-off switch; a power-supply switch 143A disposed on a power line 140A for the drive circuit 150A; and a control unit 130, wherein the control unit 130 switches a control terminal of the cut-off switch 55A from a high voltage to a low voltage, and then turns off the power-supply switch 143A.
(FR)
L'invention concerne un circuit de protection (120) d'un élément de stockage d'énergie, comprenant : un interrupteur de coupure (55A) permettant d'interrompre le courant électrique dans l'élément de stockage d'énergie ; un circuit d'attaque (150A) permettant d'attaquer l'interrupteur de coupure ; un interrupteur d'alimentation électrique (143A) disposé sur une ligne électrique (140A) destiné au circuit d'attaque (150A) ; et une unité de commande (130), l'unité de commande (130) commutant une borne de commande de l'interrupteur de coupure (55A) d'une haute tension à une basse tension, puis éteignant l'interrupteur d'alimentation électrique (143A).
