Bump4life's SuperCapacitor Overview and Testing

Recommended Posts

I've been testing and testing Supercaps all year and so far the best results are Batts+ Caps together.

Criteria for "Good" is avg. power over time, consistent power curve over time, reliability, charge efficiency, peak power, and duration of play.

maybe you can bring some points to the table then so i can add to the intro!

Can't release any of my test notes or too much info until the products release Jan 14.

But

In a standard vehicle charging system. (12V batt and alternator), Caps can be used to reduce stress and duty cycle posed on the battery during times of charge/ discharge.

This extends the life of the battery and maintains a higher voltage over time.

Different ratios of cap size to battery size can be used for different goals for the electrical system.

Large batts with small caps are useful as a buffer which extends battery life by reducing strain on the battery. This will also level the power curve over time to a small amount over what a battery alone can deliver. Very useful for low-mid level power audio systems that play music daily only.

Small Batts with Large Caps or many banks of Caps are useful for peak power in short bursts with the ability to play long periods at a lower power level but still a higher power level than when using batteries alone. This is more of the high powered cars that compete in SPL and also play daily music.

A More equal ratio gives a much more flat power curve over time at a substantially higher level than when using batteries alone. Since the caps charge faster than batts and drain on the batts is limited, re-charge times are decreased, making voltage available on demand during high powered music sessions. This is useful for any power level demo system or daily play ground pounder types.

when you say equal ratio, do you mean equal in joules/stored energy? or how are you comparing batteries to capacitors? in what units are you comparing to say x capacitors equals x batteries?

Soooo. I have 2 banks of the 2.5, 2500F. If I wanted to add on and can only find the newer, higher voltage ones, can I run them together since I will be charging at the same voltage anyways? if not I will have to scrap 12 perfectly good caps....

F to aH

50F is balanced to a 20aH Batt.

200F to a 80aH Batt

500F to a 200aH Batt.

Small Batt to large Cap ratio would be 500F to 20aH

Large Batt to small Cap ratio would be 50F to 200aH

Or any figures similar to those.

awesome. thanks for that insight!!

you can add on. no issues. you just cant charge over 15 volts.

caps suck nobody buy them :ehh:

misinformed much? unless you were being sarcastic.

Pretty sure the :ehh: gives it up as sarcasm. lol

In for more discussion and learning. :)

The downside of using batteries and caps is the potential difference. Caps stay at the charging voltage even when not being charged. Batteries drop back down to resting voltage. So what you get running both is the alt charging the caps which charge the batts and essentially render them useless because batteries love being charged and will take quite a bit of power. Now that being said using caps without batteries means you need more charging to keep the voltage in a safe range, but this is in turn a good thing because let's be honest running 10k on a couple batteries and an upgraded alt is not proper electrical. Caps are better than batteries given you have the ability to properly run the power you have. They do fine for daily as long as you can charge them correctly and have enough reserve for your power.
