Control of power metering in electrical circuits for bicycle with motor/generator assistance
摘要
<p>A control circuit is described for metering the power to electrical loads on a bicycle which has an auxiliary drive (10). This works on one of the wheels and has a motor/generator (11). There are signal transmitters (21 to 23) for the bicycle state, feeding their signals to a microcontroller (14) which acts on the power electronics (13). The microcontroller apportions the battery power not only to the lamps but also to the motor/generator. Relevant data for the built-in program are the battery's state of charge and the bicycle speed, which determine the power flow of the motor/generator when acting as a generator to charge up the battery and also the bicycle speed during braking when travelling downhill.</p>
