I have been watching videos on super capacitor jump starters for cars. I figured out about 90% of how they work, but there is one last thing I don't understand. The jump starters use a boost conver...

May 4, 2015 · can withstand 150mA for 10-20 seconds when charging the capacitor from 0V It cannot. Maximum voltage is 5,5 volts, and its ESR is 65 Ohms => max current is about 85 mA. What is the …

Nov 12, 2023 · Why the super-capacitor if you want to modify the electronics to ignore the absence of a battery to begin with?

Mar 23, 2022 · I have some 2.7 V, 500 F supercapacitors and I would like to quickly charge them from two 18650 VTC6s in parallel. I made this simple circuit and I would like to make sure it works before I …

Feb 13, 2025 · Rather than using supercapacitors, it sounds to me like a good quality power management circuit can provide the motors with high current for short periods of time and then return …

What's the formula to calculate how many seconds a supercapacitor can provide power when employing a buck/boost converter? Also, how different would that calculation be when using a pair of superc...

Jul 6, 2018 · Can I charge series of 4 Maxwell BCAP3000 supercapacitors with constant current method using an adjustable Power Supply, and exceed the voltage rated for single cell? What I mean is to …

Apr 14, 2022 · Most RTC chips have a VBATT input for backup power supply; besides a battery, you can use a supercap there, e.g. using the following scheme: simulate this circuit – Schematic …

May 25, 2023 · I am trying to simulate a super capacitor in LTspice but it is not giving me the correct discharge time as it should be theoretically. Has anyone also faced this issue? Please let me know …

Feb 11, 2019 · I find some people connect a super capacitor like (16v 88F capacitor bank) in parallel with the 12v 100Ah solar battery to optimize the surge current draws from the battery due to running …
