A method of developing a charging profile for charging a lithium-ion battery. A first phase of charging is at a constant current level, with the constant current level selected on the basis of battery resistance during charging and differential voltage (dV/dQ) analysis. A switch point is selected on the basis of a state of charge (SOC) of the battery when dV/DQ values increase. Next is an increasing voltage charging phase, with the voltage rate selected on the basis of charge acceptance and charge time.
