Application: Balancing temperature of battery management system circuits (Patent ID: US20240186814A1)
The patent filed by Infineon Technologies AG describes a circuitry designed to measure individual battery cells within a battery pack and make necessary corrections to address environmental differences between the cells and their associated measuring circuits. The system includes multiple cell supervision circuits (CSCs) to monitor and manage subsets of battery cells, with temperature variations in the battery pack potentially affecting the internal regulation circuit that generates a reference voltage for cell voltage determination. An external regulation terminal controls a pass device to share power between the pass device and the internal regulation circuit, managing the temperature of each CSC based on measurements from a temperature sensor integrated with the measurement circuit.
The claims detail the components and functions of the measurement circuit, including connection terminals for battery cells, an internal regulation circuit, and an external regulation terminal connected to a pass device for voltage regulation. The system also involves a power sharing control loop with a temperature sensor and control circuit to adjust the supply voltage based on temperature measurements. Additionally, the patent outlines a method for receiving temperature indications, comparing them to setpoints, and adjusting the power sharing setpoint accordingly by controlling the pass device via the external regulation terminal. The system can be applied to battery management circuits for charging and discharging battery cells, with the ability to maintain consistent temperatures across multiple measurement circuits within a battery pack.
