Abstract: A management method of an electrochemical device, includes: when the electrochemical device is in a preset state, measuring a predetermined parameter of the electrochemical device, and in response to the predetermined parameter meeting a preset condition, performing at least one discharge-charge operation on the electrochemical device. The discharge-charge operation includes: discharging the electrochemical device to a second voltage threshold, and charging the electrochemical device to a third voltage threshold. The second voltage threshold is less than a first voltage threshold, the first voltage threshold is a limited charge voltage of the electrochemical device, and a difference between the third voltage threshold and the first voltage threshold is not greater than 20%.
