Abstract
An electronic device, a charging method for an electrochemical device, a terminal and a storage medium. The electronic device includes an electrochemical device that satisfies the following features: in a first stage of a charging process, a state of charge (SOC) of the electrochemical device being less than or equal to X, 70%≤X<100%. An average charging current when the SOC of the electrochemical device is less than or equal to 40% is A, an average charging current when the SOC of the electrochemical device is between 40% and X is B, and A<B. The electronic device can improve the cycle life of the corresponding electrochemical device with a charging time close to that of the current fast charging.
