BATTERY CHARGING APPARATUS AND APPROACH |
| 摘要 |
Various methods, apparatuses and systems are directed to battery-charging applications. As may be consistent with one or more embodiments discussed herein, a charging current for charging a battery is modulated, and the frequency of the modulated charging current is set based upon an impedance of the battery. Temperature of the battery is estimated based upon the impedance exhibited by the battery, while the battery is charged with the modulated charging current. In various implementations, the battery charging rate is controlled based on the estimated temperature. |

1. An apparatus comprising:
a first circuit configured and arranged to modulate charging current for charging a battery, and to set the frequency of the modulated charging current based upon an impedance of the battery; and a second circuit configured and arranged to estimate temperature of the battery based upon the impedance exhibited by the battery while the battery is charged with the modulated charging current. |
