Abstract:
1. A power control apparatus for a bicycle that uses a first power supply and a second power supply to provide electrical power comprising: a voltage sensor for sensing a voltage from the first power supply; a control unit coupled to the voltage sensor and coupled for receiving power from the first power supply and the second power supply; wherein the control unit comprises: wherein the control unit outputs power from the first power supply when the voltage sensed by the voltage sensor is above a first selected value, wherein the control unit outputs power from the second power supply when the voltage sensed by the voltage sensor is below a second selected value, and wherein the voltage sensor actually switches the first power supply switch and the second power supply switch a second power supply voltage sensor for sensing a voltage from the second power supply, wherein the control unit is coupled to the second power supply voltage sensor, wherein the control unit outputs power from the first power supply when the voltage sensed by the second power supply voltage sensor is below a third selected value, and wherein the control unit outputs power from the second power supply when the voltage sensed by the second power supply voltage sensor is above a fourth selected value.
