How to Make a 12V Capacitor Battery

A capacitor battery, also known as a supercapacitor or ultracapacitor, is a device that stores energy through electrostatic double-layer capacitance and electrochemical pseudocapacitance. It has a higher power density and longer lifespan compared to traditional batteries. In this article, we will guide you on how to make a 12V capacitor battery.

Materials Needed

  • 2 x 6600F 2.7V Capacitors (or similar)
  • 1 x 12V Capacitor Battery Management System (BMS)
  • 1 x Aluminum or Copper Busbar
  • Electrical Wire (10 AWG or thicker)
  • Heat Shrink Tubes
  • Electrical Tape
  • Wire Connectors
  • A Multimeter (optional)

Step 1: Connect the Capacitors in Series

To make a 12V capacitor battery, you need to connect two 2.7V capacitors in series. This will give you a total voltage of 5.4V. To connect the capacitors, follow these steps:

Connect the Positive Terminal of Capacitor 1 to the Negative Terminal of Capacitor 2

  • Connect the positive terminal of the first capacitor to the negative terminal of the second capacitor using a wire. Make sure the connections are secure and not touching any metal objects.

Insulate the Connections

  • Use heat shrink tubes or electrical tape to insulate the connections. This will prevent any short circuits or electrical shocks.

Step 2: Add the Capacitor Battery Management System (BMS)

A BMS is essential to prevent overcharging or over-discharging of the capacitors. It will also balance the voltage and current between the two capacitors. Connect the BMS to the capacitors according to the manufacturer's instructions.

Connect the BMS to the Capacitors

  • Connect the positive terminal of the capacitors to the BMS's positive terminal.
  • Connect the negative terminal of the capacitors to the BMS's negative terminal.

Step 3: Add the Busbar and Wire Connectors

A busbar is used to connect the capacitors and BMS to the wires. Use an aluminum or copper busbar and connect it to the capacitors and BMS.

Connect the Busbar to the Capacitors

  • Connect the busbar to the positive terminal of the capacitors.
  • Connect the busbar to the negative terminal of the capacitors.

Connect the Wire Connectors

  • Connect the wire connectors to the busbar.
  • Connect the wires to the wire connectors.

Step 4: Insulate the Battery

Use electrical tape or heat shrink tubes to insulate the entire battery. This will prevent any short circuits or electrical shocks.

Step 5: Test the Battery

Use a multimeter to test the battery voltage and current. Make sure the voltage is around 12V and the current is within the recommended specifications.

Safety Precautions

  • Always handle the capacitors and wires with care to prevent electrical shocks or short circuits.
  • Use protective gear such as gloves and safety glasses when working with electrical components.
  • Make sure the battery is kept away from children and pets.

Conclusion

Making a 12V capacitor battery is a relatively simple process. By following these steps and using the right materials, you can create a high-power capacitor battery that can be used for a variety of applications. Remember to always follow safety precautions when working with electrical components.
