Chery Automobile Co., Ltd. has filed a patent application for a thermal management control system designed specifically for rapid charging scenarios of new energy vehicle batteries. The application, titled “Thermal Management Control Method and System for Fast Charging Scenarios of New Energy Vehicle Batteries,” was submitted to the National Intellectual Property Administration on February 2025, and the patent publication number is CN 119821238 A.
The patent summary indicates that this invention relates to a method and system for managing the thermal conditions of batteries during quick charging, falling under the category of automotive thermal management technology. The system utilizes a battery management module to collect real-time data on the environmental temperature, the current temperature of the battery, and the remaining battery charge. It processes this information using fuzzy control algorithms and centroid methods to determine the activation coefficient for thermal management control.
Subsequently, the vehicle controller retrieves this activation coefficient to establish the operational mode for battery thermal management and generates the necessary control commands. The battery thermal management device then receives these commands and sets up either a battery air-cooling circuit or a direct cooling circuit using refrigerant.
This innovative approach allows for the optimal thermal management mode to be determined based on real-time environmental and battery temperature data, achieving effective cooling of the battery and enhancing energy efficiency. It addresses the critical safety risks associated with overheating batteries, which can lead to significant charging efficiency losses.
