Title:
BATTERY TEMPERATURE MEASUREMENT SYSTEM AND TEMPERATURE MEASUREMENT CONTROL METHOD THEREFOR, AND ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/060625
Kind Code:
A1
Abstract:
Provided in the present application are a battery temperature measurement system and a temperature measurement control method therefor, and an electric vehicle. The battery temperature measurement system comprises: a cell system, cell information collectors, a temperature collection system and a BMS main controller. The cell system comprises a plurality of cell sets; there are a plurality of cell information collectors, which are connected to the plurality of cell sets; and the BMS main controller is connected to the temperature collection system and the plurality of cell information collectors, and the BMS main controller receives collected information from the temperature collection system and the cell information collectors, and controls the cell system according to the collected information. Voltage information of cells and temperatures of cell aluminum bars are transferred to a BMS main controller by means of cell information collectors, and temperatures of the cells and a battery internal environment temperature are transferred to the BMS main controller by means of a temperature collection system, such that overall temperature measurement of the interior of a battery is realized, thereby solving the problem in the prior art of the monitoring of the internal temperature of a battery pack not being accurate enough.
