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.

First claim

What is claimed is:

1. A method comprising:
receiving, from a battery monitoring system of a vehicle, data for prediction of a deep discharge state of a traction battery of the vehicle at a computer remote from the vehicle;
transmitting by the computer a first warning signal to the battery monitoring system responsive to determination that a period of time until an expected deep discharge as derived from the data is less than a predetermined deep discharge warning time period that depends on a current location of the vehicle; and
transmitting by the computer a second warning signal responsive to an absence of a received confirmation signal from the battery monitoring system within a predetermined reacting time period, wherein the confirmation signal is initiated based on receipt of the first warning signal by the battery monitoring system.

2. The method as claimed in claim 1 , wherein the data comprise operating data of the vehicle.

3. The method as claimed in claim 1 , wherein the period of time is derived via a battery model that is stored in a memory that can be accessed by the computer.
