| 11. | The battery voltage may rise to be close to the charger voltage so that the charging current decreases significantly.
|
| 12. | Q1 is firmly saturated in the beginning by the " forcing " C2 charging current added to R3 current.
|
| 13. | I monitored the current carefully, and controlled it using a variable resistance, trying to match the recommended charging currents.
|
| 14. | A disadvantage is, according to the researchers that the bigger the battery, the greater must be the charging current.
|
| 15. | By sampling the current just before the potential is changed, the effect of the charging current can be decreased.
|
| 16. | I designed a charger circuit with charging voltage of 5V and charging current of 240mA for 4 batteries in series.
|
| 17. | During this phase, the charge current decreases gradually to a small residual value that compensates for any self-discharge of the battery.
|
| 18. | In all lead-acid battery designs, charge current must be adjusted to match the ability of the battery to absorb the energy.
|
| 19. | It also ensures that they are not overcharged when nearing full charge and not overheated when a large charge current becomes available.
|
| 20. | This fall, Baylor University in Waco, Texas, will charge freshmen $ 15, 700, 33 percent more than it charged current first-year students.
