Lithium battery cycle life refers to the number of charge-discharge cycles a lithium battery can undergo before its capacity drops to a specified level. When you charge a lithium battery, lithium ions move from the positive electrode (cathode) to the negative electrode (anode) through an electrolyte. During discharge, these ions move back.
The battery management system (BMS) is an essential device to monitor and protect the battery health status, and the PHM as a critical part mainly includes state of health (SOH) estimation and remaining useful life (RUL) prediction [11, 12].SOH is mostly defined as the ratio of current available capacity to initial capacity, and RUL is usually considered to be the
