US 2014/0210638 A1 · METHOD AND DEVICE FOR MONITORING AT LEAST ONE TRACTION BATTERY OF A MOTOR VEHICLE

Abstract

A method for monitoring at least one traction battery of a motor vehicle includes the steps of determining basic data for the prediction of a deeply discharged state of the at least one traction battery by a battery monitoring system associated with the motor vehicle, transmitting the basic data to an external computer via a first communications link, determining an expected point in time of the deep discharge by the external computer, and transmitting a first warning signal to a first monitoring instantiation of the motor vehicle that can be specified if the determined point in time of the deep discharge is reached apart from an early warning time. A device for monitoring at least one traction battery of a motor vehicle is also disclosed.
