6 / 28 page 6 ICS1712 Cells that are not thoroughly conditioned or possess an unusual cell construction may not have a normal voltage profile. The ICS1712 uses an alternate method of charge termination based on a slight decrease in the voltage slope to stop charge to cells whose voltage profile is very shallow. This method looks for a flattening of the voltage slope which may indicate a shallow peak in the voltage profile. The zero slope point occurs slightly beyond the peak voltage and is shown on the voltage curve graph. Charge Termination Methods Several charge termination schemes, including voltage slope, temperature slope, maximum temperature and two overall charge timers are available. The voltage slope and negative voltage slope methods may be used with or without the temperature slope and the maximum temperature method. Maximum temperature and the fast charge timer are available as backup methods. Voltage Slope Termination The most distinctive point on the voltage curve of a charging battery in response to a constant current is the voltage peak that occurs as the cell approaches full charge. By mathematically calculating the first derivative of the voltage, a second curve can be generated showing the change in voltage with respect to time as shown in Figure 6. The slope will reach a maximum just before the actual peak in the cell voltage. Using the voltage slope data, the ICS1712 calculates the point of full charge and accurately terminates the applied current as the battery reaches that point. The actual termination point depends on the charging characteristics of the particular battery. Figure 6: Voltage and slope curves showing inflection and zero slope points |
