The present invention provides a control device (10) for a secondary battery (110) that can limit the power value of the secondary battery (110) per unit time without excessively limiting the allowable power value of the secondary battery (110). The control device (10) for the secondary battery (110) includes an allowable power setting unit (421) and an allowable power limiting unit (422). The allowable power setting unit (421) sets an allowable power value for the secondary battery (110) during at least one of discharging and charging, based on specified information of the secondary battery (110). The allowable power limiting unit (422) limits the power value before the power value of the secondary battery (110) reaches the allowable power value. The allowable power limiting unit (422) limits the power value in stages at two or more different ratios.

A multi-channel amplifier system for power supplies with specific power output ratings. The system includes first and second output channels, each containing a power amplifier, an adjustable voltage limiter, and an adjustable impedance circuit. A constraint controller with predefined partial power settings is able to adjust the voltage or impedance based on specific constraint patterns. Power distribution balance between output channels is regulated by a multi-contact switch. Real-time data of the output channels is acquired by a sensing system including temperature, current, and voltage sensors, allowing dynamic adjustments within predefined ranges. The system also integrates an input signal digital signal processor (DSP) compressor or limiter that works in conjunction with a microcontroller to limit audio signals based on specified thresholds. This innovative design enables efficient and adaptive power distribution without the need for a graphical user interface, making it ideal for various audio applications.

The application relates to the technical field of photovoltaic energy storage system scheduling control, and particularly discloses a multi-time scale scheduling method for a photovoltaic energy storage system. Each terminal collects local data to form a starting data packet. An elected master node generates an energy storage power candidate sequence by adopting counterfactual rolling deduction, and adds a smooth slope limit value which changes adaptively with a state of charge section to form a proposal instruction set. A slave node filters through a feasible region template and aggregates signature fragments to perform double verification, locks a sequence with an approved signature number exceeding a Byzantine fault tolerance threshold as a global power control sequence, and divides an asymmetric transition window according to the smooth slope limit value, so as to approach a target value by using a variable step length and suppresses oscillation by using a hysteresis band. When a state of charge deviates from a preset track and exceeds a trigger threshold, adjacent terminals initiate a rapid local voting to correct a subsequent power setting value. The application can eliminate power rebound and tolerate communication uncertainty.
