Anhui Yijiatong Battery Co., Ltd. has been granted a patent for a failure-resistant battery thermal management control system and vehicle, enhancing the reliability of thermal management systems. According to the National Intellectual Property Administration, the patent, titled “A Failure-Resistant Battery Thermal Management Control System and Vehicle,” has the authorization announcement number CN 222698336 U, with an application date of July 2024.
The patent summary indicates that this utility model introduces a thermal management control system featuring a Battery Management System (BMS), temperature sensors, and a Thermal Management System (TMS). The temperature sensors collect temperature data from the battery, with their output connected to the input of the BMS. The BMS then outputs heating or cooling drive signals to the drive end of the TMS, which is responsible for operating heaters or coolers. Additionally, the control system includes a temperature switch located within the battery module; the switch contacts are connected in series between the BMS output and the heating drive end of the TMS.
The advantages of this utility model are significant. It introduces a redundant control mechanism via the switch to manage the TMS operation, thereby preventing continuous abnormal heating of the battery due to software or BMS chip anomalies. This improvement enhances the reliability of the thermal management system and mitigates potential risks of thermal runaway.
According to Tianyancha, Anhui Yijiatong Battery Co., Ltd. was established in 2016 and is located in Xuancheng City. This company primarily engages in the manufacturing of electrical machinery and equipment. Its registered capital is approximately 126.89 million RMB, with a paid-in capital of around 112.86 million RMB. Data analysis reveals that the company has invested in nine enterprises, participated in 26 bidding projects, and has 16 trademark records along with 174 patent records. Furthermore, the company holds seven administrative licenses.
