Abstract
A battery system includes an auxiliary battery releasably coupled to a main battery. The main battery includes a charge controller and has a first output voltage. The main battery is configured to be electrically coupled to a bicycle drive unit and supply power to the drive unit. The auxiliary battery has a second output voltage. The auxiliary battery is releasably coupled to the main battery in series such that a total output voltage of the main battery and auxiliary battery is equal to a sum of the first and second output voltages.
Claims21
A drive system for a bicycle comprising:
- a drive unit;
- a main battery comprising a charge controller and having a first output voltage, wherein the main battery is configured to be electrically coupled to the drive unit and supply power to the drive unit;
- and
- an auxiliary battery having a second output voltage, wherein the auxiliary battery is releasably coupled to the main battery in series such that a total output voltage of the main battery and auxiliary battery is equal to a sum of the first and second output voltages.
A battery system for a bicycle comprising:
- a main battery comprising a charge controller and having a first output voltage, wherein the main battery comprises a bicycle mounting arrangement;
- an auxiliary battery having a second output voltage, wherein the auxiliary battery is moveable relative to the main battery between a first engaged configuration, wherein the auxiliary battery is releasably coupled to the main battery in series such that a total output voltage of the main battery and auxiliary battery is equal to a sum of the first and second output voltages, and a first disengaged configuration, wherein the auxiliary battery is decoupled from the main battery.
A battery system for a bicycle comprising:
- a main battery comprising a charge controller, wherein the main battery has a first output voltage, wherein the main battery is configured to be electrically coupled to a drive unit and supply power to the drive unit;
- an auxiliary battery having a second output voltage, wherein the auxiliary battery is releasably coupled to the main battery in series such that a total output voltage of the main battery and auxiliary battery is equal to a sum of the first and second output voltages;
- and
- a switching network operably coupled to the main battery and the auxiliary battery, wherein the switching network is configured to connect the main battery and auxiliary battery in parallel or in series with a charge source.
