Abstract

Method for evaluating the reliability of a monitoring system for a battery cooling system of a motor vehicle. Method for evaluating the reliability of a monitoring system for a battery cooling system from data collected from a set of vehicles, each vehicle comprising: - a battery equipped with a cooling system, - a monitoring system for the cooling system, and - a means of communication with a centralized server.The process includes: - detection, by a vehicle in the group, of an initial fault diagnosis, then - from a time of initial determination of an initial fault diagnosis, an iteration on determining an initial reliability indicator of the monitoring system calculated by each vehicle in the first group, and - a third step of collecting, by the centralized server, the current value of the first reliability indicator for each vehicle in the first group.
