I am looking into developing a hybrid buggy and have a question plaugeing my mind. Can you use an electric motor as a generator as well? Theoretically I assume so, but rpm is essentiall for charging, or at least efficient charging.

Basically can you drive the vehicle on gas while the electric motor chargers the batteries and when needed shut off the IC engine and turn on electric motor. I believe it's feasible, but what constraints am I looking at?

Also does anyone know of a good source for finding electric motors and batteries for such projects? Thinking approx 80 hp and a lot of torque.

Yes, in theory an electric motor can be used as a generator. This is known as regenerative braking, which is a common feature on many hybrid and electric vehicles. The RPM of the motor is important for efficient charging, though it is possible to use other methods such as a DC/DC converter to convert the voltage from the motor to the required voltage for the batteries. As for sources for electric motors and batteries, there are many companies that offer off-the-shelf solutions for these components. Companies such as Efficient Drivetrains, Inc and Electric Motors Corporation offer electric motors and batteries suitable for different types of hybrid and electric vehicles. Additionally, there are many suppliers and manufacturers of electric motors, batteries, and other components that can be used for custom projects.
 

1. Can an electric motor be used as a generator in a hybrid buggy?

Yes, an electric motor can be used as a generator in a hybrid buggy. This is known as regenerative braking, where the motor acts as a generator to convert the kinetic energy of the vehicle into electrical energy, which is then stored in the battery for later use.

2. How does regenerative braking work in a hybrid buggy with an electric motor?

Regenerative braking works by using the electric motor as a generator when the vehicle is decelerating. The motor creates resistance to slow down the vehicle and this resistance is used to generate electricity, which is then stored in the battery. This process helps to increase the overall efficiency of the vehicle.

3. What are the benefits of using an electric motor as a generator in a hybrid buggy?

Using an electric motor as a generator in a hybrid buggy has several benefits. It helps to improve the fuel efficiency of the vehicle, reduces emissions, and increases the overall range of the vehicle. It also helps to extend the life of the vehicle's braking system as regenerative braking reduces the wear and tear on the brake pads.

4. Are there any limitations to using an electric motor as a generator in a hybrid buggy?

One limitation of using an electric motor as a generator in a hybrid buggy is that it can only generate electricity when the vehicle is decelerating. This means that it cannot be used for continuous power generation like a traditional generator. Additionally, the amount of electricity generated may also be limited by the size and capacity of the motor.

5. How can the use of an electric motor as a generator benefit the environment?

Using an electric motor as a generator in a hybrid buggy can benefit the environment in several ways. By reducing the reliance on fossil fuels, it helps to reduce carbon emissions and air pollution. It also helps to conserve natural resources and decrease the overall carbon footprint of the vehicle. Additionally, the use of regenerative braking can also contribute to a more sustainable transportation system.
