Document Type and Number:
WIPO Patent Application WO/2020/051756
Kind Code:
A1
Abstract:
A method for operating a battery system (10) in an electric vehicle, the battery system (10) comprising at least one battery module (5) with at least one battery cell (2), and a management system (20), capable of determining a battery temperature of the battery system (10) and a battery current flowing through the battery system (10) and capable of reducing said battery current, wherein the battery current is reduced when the battery temperature is between a first threshold and a second threshold and when the battery current is greater than a first limit value (L1); the battery current is reduced by means of a control loop when the battery temperature is between the second threshold (T-Der) and a third threshold (T-Max); and the battery current is turned off when the battery temperature is greater than the third threshold (T-Max). A battery system (10), comprising at least on battery module (5) with at least one battery cell (2), and a management system (20), capable of determining a battery temperature of the battery system (10) and a battery current flowing through the battery system (10) and capable of reducing said battery current, wherein the management system (20) is designed to execute the method.
