PROBLEM TO BE SOLVED: To provide a charging method, a charger, and a charging system, wherein the charge and discharge cycle performance is improved, and the charging time can be shortened. SOLUTION: Based on a knowledge that especially in a non-aqueous electrolyte battery, when the battery temperature is 45°C or more, if the charging termination current value of the constant current and constant voltage charging is completed at 0.2 ItA or more, the charge and discharge cycle is improved rather than deteriorated, and this charging method, charger, and charging system are applied with this idea. The charging system has a temperature detection means, a charging method judgement means to select one from a plurality of charging methods, and a charger capable of realizing the plurality of charging methods. The above plurality of charging methods include this charging method. COPYRIGHT: (C)2006,JPO&NCIPI
