Material preparation? Supercapacitors can be divided into four parts: double electrodes, electrolytes, current collectors and separators.
Next, I will explain in detail the preparation process of a capacitor.
Component list: Farah capacitor, the core component of Farah capacitor bank.
Supercapacitor is a kind of physical secondary power supply with super energy storage capacity and powerful pulse power. It is developed according to the theory of electrochemical electric double layer, so it is also called electric double layer capacitor. The basic principle is that when the electrode is charged, the surface charge of the electrode in the ideal polarization state will attract the opposite ions in the surrounding electrolyte solution, so that these ions will adhere to the electrode surface to form a double charge layer, forming an electric double layer capacitor. Because the distance between the two charge layers is very small (generally less than 0.5mm) and the special electrode structure is adopted, the surface area of the electrode is increased by 10 thousand times and the capacitance is very large. The advent of supercapacitors has achieved a leap from microfarad level to farad level, completely changing people's traditional impression of capacitors. At present, supercapacitors have formed a series of products, achieving a capacitance of 0.5- 1000F, a working voltage of 12-400V and a maximum discharge current of 400-2000A a. ..
Farah capacitor bank (with 60A insurance)? 58F/ 16V？ 1 group
DC relay race? (A set of normally open/normally closed contacts)? 30Adc/ 12VDC？
Safe deposit box (with insurance) 15A? 1
Low drop and high current diode? 80A？ 1
Auxiliary materials (lugs, various wires, quick plugs and sockets, etc.). )? several
Design your own capacitance control pattern diagram.
Making circuit control box
Assemble the diode, fuse box and relay into the control panel and box.
Setting capacitor protective layer
Make plug
After the above production is completed, the next step is to start the installation in the car. Place the capacitor on the right foot of the driver's seat.
Precautions for DIY:
1), capacitor bank precharge: 12VDC. When charging, add 10 ohm /5W resistor to limit the current, otherwise it will burn out 60A fuse or charging power supply;
2) Before starting wiring, disconnect the negative electrode of the automobile battery;
The control line 25 is yellow on a red background, the output line of the capacitor is the largest blue line, and the line connected to the positive electrode of the battery is white on a thick red background.
The use of supercapacitors:
1), first connect the battery cathode;
2) Use a multimeter to measure the voltage difference between the positive and negative poles of the battery and the positive and negative poles of the capacitor bank. You can directly plug in the plug, otherwise the voltage of the capacitor will be adjusted.
Finally, after making the capacitor yourself, remember to pay attention to the safety of use. Before use, remember to check whether the positive and negative directions of your capacitive load and connection are correct. Well, through the above explanation, I believe everyone has understood the manufacturing process of supercapacitors. This kind of production skill quickly goes home and gets up.
