Regenerative Braking System On Homemade Electric Car

If anyone still remembers, back in mid 2008, the world was having an energy crisis. Global crude oil prices were hitting a high of US150 per barrel. Never has the cost of sweet crude reached that level before. The effect was chaos around the world.

Local gasoline prices shot through the roof. People driving large gas guzzler was having a tough time feeding their pride SUVs. Some had no choice but to abandon their vehicle at home and use the public transportation. Luckily, oil prices are at a reasonable level now…or is it?

As of the time I’m writing this post, crude oil is slowly creeping back to US60 per barrel and climbing…

Okay, I wanted to write something on [tag-tec]regenerative braking system[/tag-tec] for Do It Yourself (DIY) electric car. I found a video on Youtube last week about a really cool homemade electric truck that has a regenerative braking system installed.

The whole setup look a bit troublesome. From the video, it is clear that the regenerative brake system is manually engaged. I don’t think the system is used to stop the EV but rather used to generate some electric power by tapping to the [tag-tec]kinetic energy[/tag-tec] of the spinning electric motor shaft.

To engage the regenerative braking system, you would have to press a button fitted on the gear knob. When you do that, it will engage a relay that will fire up the friction clutch. The clutch will transfer the kinetic energy from the motor to spin an alternator to create electricity.

The electric power generated by the alternator can be flowed back to the batteries. It will be interesting to know how much additional drive mileage the regenerative braking system is adding to the electric car.

Should we use regenerative braking system on a homemade electric car? I think it all depends on the EV owner. Personally, I think it will increase your electric car conversion cost and the electric power generated may not add any significant drive mileage to the EV. There is also additional work to test, fit and connect the system to make it work.

I believe [tag-tec]pure electric car[/tag-tec] will be the wave of the future for the world transportation system. If you are keen to find out how to convert your gasoline driven car to run on electricity, check out my EV conversion guide review.

    is there in the market any kit for regenerative braking that i can mount it on my car personally?
    thanks.

    Hi Zadnia,

    Is your car a gasoline driven vehicle of electric car?

    I’m working on a project in my University, building an EV. The thing is we (the team) want
    to incorporate a regenerative braking system; but articles about this topic are bare and not really developed. So I would appreciate so much if you could send me some information about that stuff, specifically the sort of regenerative brakes that are currently being used and the corresponding features.
    By the way, this compilation of videos has resulted really valuable to me: Thank you.

    When choosing brake calipers, the best thing that you can do is opt for ones that are better ventilated. The reason is because the calipers heat up the brake pads and brake rotors.

    What do you think?regentive braking happens when the throtele is closed and the moters power is genrating power, brakes are not applied or used in the system. I have a duel moter setup that regenarates while excelarating using 2 electric vichicles in 1. and has gone 1300 miles on a charge.
