Abstract
The present disclosure illustrates a compensation circuit of an energy storage device. The compensation circuit includes a first error amplifier, a switching unit, a first RC network, a voltage recording module and a logic control module. The switching unit selectively connects an output end, a first input end of the first error amplifier or the voltage output end. A resistance value or a capacitance value of the first RC network changes with different sensing loops of the energy storage device. When the energy storage device switches the sensing loop, a detection circuit outputs a detecting signal. The logic control module controls the switching unit to connect the first input end to the output end, and controls the voltage recording module to output a preset output voltage to the voltage output end for stabilizing a first capacitor of the first RC network.
