Application: Power storage apparatus, charging method, and program (Patent ID: US20230411713A1)
The patent filed by Kyocera Corp. describes a power storage apparatus that includes a power storage module with multiple batteries, a temperature acquirer, a state-of-charge calculator, and a charge controller. The temperature acquirer measures the temperature of the module, the state-of-charge calculator determines the state of charge, and the charge controller charges the module based on the temperature and state of charge. The charge controller adjusts the current value based on the temperature and state of charge, ensuring efficient and safe charging.
Additionally, the patent includes claims for classifying the state of charge and temperature into groups to set appropriate current values for charging. It also covers scenarios where the temperature exceeds a threshold value, the use of a current value setting table to determine charging parameters, and the incorporation of a state-of-health calculator to consider the overall health of the power storage module. The patent also outlines a charging method and computer program instructions for implementing the described charging process effectively and accurately. Overall, the patent focuses on optimizing the charging process for power storage modules to enhance performance and longevity.
