System and method for monitoring the connection of battery terminals to an electrical system of a motor vehicle, and motor vehicle comprising such monitoring system

A system for monitoring the connection of the terminals of at least one battery which is suitable to be connected and provide auxiliary electrical power to an onboard electrical distribution system of a motor vehicle, the monitoring system being comprising:

• an electronic control unit;
• a sensor which is adapted to be connected to at least one of the terminals of the battery and to provide in input to said electronic control unit signals indicative of the electric power currently generated by the battery;
• wherein the electronic control unit is configured, based on said signals received in input:
• to monitor and compare at least one electrical parameter of the electric power currently generated by the battery with at least one predefined reference condition which is indicative, relative to the monitored electrical parameter, of a correct connection of the terminals to the onboard electrical distribution system;
• and
• to output an alert signal indicative of an incorrect connection of at least one of the terminals of the battery to the onboard electrical distribution system when the at least one electrical parameter monitored exceeds said predetermined reference condition.
