Abstract: In a method of charging a battery, a charging control device obtains a battery parameter that includes an electrode parameter of the battery and one or more of a structure parameter, a manufacturing process parameter, an electrical parameter, an electrolyte parameter, a diaphragm parameter, and a thermophysical parameter of the battery. The charging control device inputs the battery parameter input into a battery model represented by an ordinary differential equation to obtain a safe charging boundary value of the battery in n cycles, where n is greater than or equal to 2 and less than or equal to N, N is a cycle life of the battery, and the n cycles refer to n cycles selected from 0 to N cycles. The safe charging boundary value is a maximum charging current in which no lithium plating occurs on the battery in different states of charge SOCs and at different temperatures.
