Application: Method and device for calibrating soc at tail end of charging or discharging of energy storage system (Patent ID: US20240159836A1)
The patent by Sungrow Power Supply Co Ltd describes a method and device for calibrating the State of Charge (SOC) of an energy storage system at the tail end of charging or discharging. The method involves acquiring real-time SOC and voltage data of a battery unit, comparing it with pre-calibrated values, and calibrating the SOC if certain conditions are met. The calibration process is tailored for both charging and discharging states, ensuring accurate SOC readings for optimal battery performance.
The device consists of processors and memory storing computer-readable instructions to carry out the calibration process. It acquires battery parameters, determines SOC calibration conditions, and calibrates the SOC accordingly. The method also includes selecting calibration values based on the battery's state and operating conditions, ensuring precise calibration. During charging, the device checks if the SOC is below a certain threshold and if the voltage is above the calibration value to meet calibration conditions. Similarly, during discharging, it verifies if the SOC is above a threshold and if the voltage is below the calibration value. This method and device provide a systematic approach to SOC calibration, enhancing the efficiency and reliability of energy storage systems.
