What is this?
This module is essentially a maintenance free battery with 708 mWh of energy that can operate down to -40 ºC without any negative influence on the performance.
Why should I have it?
Because compared to bare supercapacitors, this module provides protection against short-circuit, over-voltage and reverse voltage. In case of over-voltage the supercapacitor can explode. If reverse voltage is applied, then the capacity of the supercapacitor dramatically decreases. The electronics embedded in the module eliminates those problems.
This module can be used in low power applications, such as, for example, Uninterruptible Power Supply (UPS), portable power supply or in energy harvesting. The module is maintenance-free and can be used in a wide temperature range (-40 to +60 C).
he Protected Supercapacitor Module is an energy storage device that contains two 350 F supercapacitors connected in series. The module provides advanced protection of supercapactors. They are protected against over-voltage, over-current and reverse voltage. The protection increases the safety and prolongs the lifetime of supercapacitors out-of-the-box. In case of over-voltage capacitors are disconnected from the charger and are slowly discharged to a safe voltage. When a safe voltage is reached, supercapacitors are reconnected to the charger again. In case of over-current the supercapacitors are protected with the resettable fuses. In case a reverse voltage of more than -0.3V is applied, the current is bypassed. A 2.54 mm pitch female connector provides the connection to the supercapacitors and to the overvoltage alarm signal. The protection circuit is encased in a custom made enclosure to prevent any contact with the terminals of the supercapacitors. The module can be charged from empty to full in 5 minutes and 15 seconds at current of 3 A.

My name is Andrejs Bondarevs and I currently reside in Sweden. I have been interested in electronics since I was a child. I got my Master's degree in Electronics couple of years ago. Currently I work in a consulting company i3tex AB as a Software and Hardware Engineer.
In my spare time I do some projects, mostly in the area of electronics and software. I share my most successful and finished projects on this website, because I thought that some people might be interested and they are. :) My most interest in the electronics area lies in the power and IoT applications. My biggest obsession is autonomous power systems.
In the moments when I am a normal person, I'm swimming, cycling, camping and travelling. I also have some interest in the finances.
