REAL-TIME TEMPERATURE MEASUREMENT METHOD FOR TRACTION BATTERY PACK

Title:

REAL-TIME TEMPERATURE MEASUREMENT METHOD FOR TRACTION BATTERY PACK

Document Type and Number:

WIPO Patent Application WO/2024/016500

Kind Code:

A1

Abstract:

Provided in the present invention is a real-time temperature measurement method for a traction battery pack. The temperature measurement and thermal field analysis of a traction battery pack are realized. A temperature field of a traction battery pack is simulated and emulated by using current and voltage information of the traction battery pack and thermodynamic parameters of a material, and the temperature field is corrected by using discrete actually-measured temperature data and by means of a deep neural network and a Kalman filter, such that an established temperature field model can more truly reflect the actual temperature field distribution of the battery pack.
