Constant voltage type
A type using electric power generated by bicycle through constant voltage regulator and invertor with no battery device.
There is no loss of generated electric energy due to storing the power in the battery and using inverter afterwards. In this regard, it has advantage in efficiency aspect, but during the time the bicycle is not used for exercise, electric power cannot be used.
Through an experience such as turning on the light or a fan using generated electric energy, the user can learn about the energy conversion process from user’s kinetic energy to electric energy.
Battery charge type/Hybrid type
In this type, the electric power generated by bicycle generator is stored in the battery and can be used at any time for various electric devices according to the charging time, battery and inverter capacity. However, some of the generated power may be lost during the processes of storing, discharging and using electric energy.
In some cases, the energy in the battery may be discharged gradually as the time goes by. Therefore, hybrid configuration can be applied with small scale solar energy generation or small wind power generation for the stable use of the generated electric power.
