Method for detecting disconnection of battery of motor vehicle, involves detecting risk of disconnection of battery by analyzing value of utilization rate, and generating warning signal when rate indicates risk of disconnection of battery
The method involves measuring a value of utilization rate representing a ratio between electric current intensity and maximum current intensity capable of providing by a power source i.e. starter-alternator (20). A risk of disconnection of a battery (10) is detected by analyzing the value of utilization rate by comparing the variability of the value of utilization rate with a threshold of maximum variability. A warning signal is generated if the analysis of the value of utilization rate indicates the risk of disconnection of the battery.
