Post Subject: Batteries vs. SupercapactiorsPosted by xandcg on: 12/5/2021
Amir,
just in case you are wondering about what I have said I think supercapacitors are better in this application, and adding to my previous reply, the main practical differences between a battery and a suppercapacitors are:
1 - batteries are quite good in storing electricity but they are rather slow charging/discharging devices, and ever if you can make them charge/discharge fast (think all these turbo charging stuff) they don't like it and so, the battery lifetime will be considerably reduced if you do. Idealistic batteries should be charged/discharged at the slower possible pace to increase (or retain) their maximum life time.
2 - supercapacitors are poor at the storage side, (IIRC) it loses in average 20% of the stored electricity per day. On the other hand, they are hell good in charging/discharging. A large industrial sized supercapacitor bank can be fully charged in just a few minutes (or rather faster) depending on the power source, with a life time often surpassing 25 years.
That said, I can't really see a reason to use batteries in this application unless you live in a location with intermittent power supply[1]; however, if you need the battery storage capacity for some reason you can yet use hybrid devices...
[1] but if the electricity goes for just a few short moments you probably would not need a batteries, anyway.
