Abstract

An electronic assembly including a first connector having a first set of terminals physically and operationally compliant with a data transmission connector standard, such as USB 2.0, and a second set of terminals distinct from the first set of terminals physically compliant and operationally non-compliant with this data transmission connector standard. An electronic controller is connected to the first connector. The controller includes a memory device to store configuration data, such as a battery charging profile, used by the controller to control a first electronic device, such as a battery charging device. The second set of terminals receive new configuration data to update the configuration data stored in the memory device. The assembly may include a specially configured data cable to interconnect the assembly to a separate electronic device to transmit the updated configuration data. The assembly may reduce the current supplied for battery charging by monitoring a battery voltage.

Claims
