Fast battery charging through digital feedback
First Claim
1. An apparatus for charging a battery, comprising:
- a charging component configured to receive an amount of voltage on a power bus connectable to an external device, wherein the charging component charges the battery powering the apparatus with the amount of voltage received;
an authentication component configured to authenticate the apparatus with the external device via a plurality of signal lines, wherein the authentication component is configured to transmit one or more authentication signals on one or more of the plurality of signal lines from the apparatus to the external device, wherein the power bus receives a default amount of voltage transmitted by the external device when the authentication component fails to authenticate the apparatus with the external device; and
a configuration component configured to transmit a modified voltage signal and a modified current signal to the external device via the plurality of signal lines when the authentication component authenticates the apparatus with the external device, wherein the modified voltage signal and the modified current signal are operable to cause the external device to modify the amount of voltage transmitted to the power bus.
