Replace your car battery with capacitors!

[whatmaycome14]

Any update to this? I'm really curious to see any benefit...

I've been very busy lately. I'll try and get this done over the next few weeks.

Yes I have seen the lasersaber youtube post but he has shown nothing currently. I am considering this but with ultracaps. There voltage rating is to low and cost serious cash.
I am hoping to salvage a 11 volt 16ah battery this way..........

mazda does this with the new skyactive vehicle

plus they have higher cycle life. Ebay has listing for voltage stablizer..... a basic capacticor bank in small box ....the claim is bettery mpg and better power distribution. At 60-90 dollars may go my own way..........

I have a lot experience using the Mazda Skyactiv system, it fully charges in about 6 seconds of deceleration/braking in gear. I think the alternators are high output 12/24v switching. I can get good mpg gains by using it, adapting your driving to take advantage of it etc

Its basically a kinetic energy recovery system which is where the efficiency gains come from, using otherwise wasted energy & converting it into stored power that provides about 2-6 mins of power Dependant on whats switched on.

This is neat, it's good to see it working in practice. I think a car pulls like 1-2W when it's switched off, which is far higher than the leakage current of a capacitor. However, to be able to leave the lights on at a stop for a while after the car hasn't been used for a week or two for example without having the voltage dip too low, I would throw a battery in albeit a lighter one.

Originally I was thinking of replacing my battery with a 36Ah Shorai (at 300 bucks it's basically 3 times the cost of an AGM lead acid battery, and supposedly they can tolerate much more cycling so it might eventually pay for itself), but seeing this makes me think a small (lithium?) battery plus capacitors for starting might be the better solution.

I'd be interested in doing this on my Lupo 3L as its has a "massive" size battery in the boot, considering its a tiny lightweight car with a 1.2 diesel engine the battery is the same size as a 4.2L truck one.

I think running this in conjunction with a small 12v battery would be the way to go.

Here's a new video. This could easily be the future of car batteries. Not only is it an easy way to lose weight from a car, but then you can phase out 35 pounds of toxic lead acid batteries from every car. Costing about the same price also helps!

Nice update on this vid... he has learned a bit since his early efforts.
