PORTABLE ENERGY STORAGE DEVICE AND METHOD FOR DYNAMICALLY ADJUSTING POWER BASED ON INTERNAL TEMPERATURE

The present invention provides a portable energy storage device and method that dynamically adjusts power based on internal temperature, based on the battery pack temperature model data, which allocates corresponding decision power at each critical decision point temperature. During the use of the energy storage device, when the power is reduced due to the increase in the battery pack temperature, if the power reduction causes the temperature to be in a decreasing stage, then during the temperature-decreasing process, the control unit will not restore the battery pack to a larger power until the temperature decrease magnitude exceeds the hysteresis temperature threshold. The present invention allows the power of the battery pack to be adjusted according to its real-time temperature, ensuring the operational safety of the device while maintaining the power at a high level. Additionally, the design of the hysteresis temperature threshold enhances the operational stability of the device.
