Abstract: Disclosed herein is an invention concerning a method for managing charging of a Li-ion battery based on at least one parameter chosen from a group consisting of a state of deterioration of the Li-ion battery and cell unbalance, the method comprising the following steps: a) determining an end-of-charge voltage value of said Li-ion battery, b) generating a control signal controlling the charging of said Li-ion battery, and c) transmitting the control signal to a charger, the control signal being generated in such a way that the Li-ion battery is charged based on the end-of-charge voltage value determined in step a), said end-of-charge voltage value being increased based on the state of deterioration of said Li-ion battery until a limit value is reached, in order to ensure a constant minimal level of required energy in said Li-ion battery is provided at a predetermined reference temperature.
