POWER-SONIC Rechargeable Batteries

Charging Efficiency

The charging efficiency (η) of a battery is expressed by the following formula:

The charging efficiency varies depending upon the state of charge of the battery, temperatures, and charging rates. Figure

21 illustrates the concept of the state of charge and charging efficiency. As shown in Figure 22. Power-Sonic batteries

exhibit very high charging efficiency, even when charged at low charging rates.
