Auxiliary power supply, method of operating auxiliary power supply, and storage device including auxiliary power supply

An auxiliary power supply includes an auxiliary power storage device configured to store power input to the auxiliary power supply, and a control circuit configured to store the power input to the auxiliary power supply within a reference amount of time after the power is input to the auxiliary power supply. Charging the auxiliary power storage device by a first current source having a preset peak current level; determining, after the reference amount of time, that the auxiliary power supply is in a slow charge state when a voltage level at which the first current source charges the auxiliary power storage device within the reference amount of time is below a reference voltage level; and in response to the slow charge state, increasing the peak current level to charge the auxiliary power storage device by a second current source having an increased peak current level greater than the preset peak current level. 本申请涉及一种辅助电源，包括被配置为存储输入到辅助电源的电力的辅助电力存储器件以及控制电路，其中控制电路被配置为：在向辅助电源输入电力之后的参考时间量内，通过具有预设峰值电流电平的第一电流源对辅助电力
