Beschreibung
Zusammenfassung:	In described examples of a method and apparatus for fast charging a battery with optimal charging, a system (400) includes a battery charger (420) for applying a voltage to a rechargeable battery (430), and a controller coupled (422) to the battery charger (420) and monitoring at least one of a battery voltage, a battery temperature and the current flowing into the battery (430). The system (400)is configured to apply a charging current from the battery charger (420) by calculating an open cell anode voltage and an anode resistance of the battery (430), and determining the charging current. In additional arrangements, lithium ion plating is prevented by the charging current. 在所描述的用于对具有优化充电的电池快速充电的方法和装置的示例中，系统(400)包括用于将电压施加到可再充电电池(430)的电池充电器(420)，和耦合到电池充电器(420)并且监测电池电压、电池温度和流入电池(430)的电流中的至少个的控制器(422)。系统(400)被配置为通过计算电池(430)的开路单元电池阳极电压和阳极电阻以及确定充电电流来施加来自电池充电器(420)的充电电流。在附加的布置中，由充电电流来防止锂离子电镀。
