METHOD FOR STOPPING THE PROPAGATION OF THERMAL RUNAWAY IN A BATTERY TANK OF AN ELECTRIC OR HYBRID MOTOR VEHICLE

Abstract

The invention relates to a method for stopping the propagation of thermal runaway in a battery tray of an electric or hybrid motor vehicle, comprising a step of measuring the temperature and/or voltage of a first electrochemical cell (E1), said dielectric fluid having a first level in said battery tray; a step of measuring the temperature and/or voltage of at least a second electrochemical cell (E2), thermal runaway propagation being detected when said second electrochemical cell has a measured temperature exceeding a second predetermined threshold temperature and/or an inconsistent voltage; and a control step (E3) of closing the first dielectric fluid distributor and the second dielectric fluid distributor, the dielectric fluid being exclusively redirected to said battery tray.
