METHODS FOR MONITORING THE STATE OF A BATTERY IN A MOTOR VEHICLE

摘要

An internal temperature of a battery is determined at defined intervals at different moments in time and is transmitted to an evaluation unit, which continuously determines a temperature gradient at least from the temperature values by dividing the temperature change in an interval by the time change in this interval. At least one limit value for the temperature gradient is stored in the evaluation unit, and the evaluation unit generates an alarm signal when the temperature gradient determined by the evaluation unit reaches this limit value.

1. A method for monitoring a battery in a motor vehicle comprising:
determining at defined intervals at different moments in time an internal temperature of the battery; determining by an evaluation unit a temperature gradient by dividing a change in the internal temperature by a time associated with one of the defined intervals; and generating by the evaluation unit an alarm signal when the temperature gradient reaches a limit value.
