[P]-CAP

[P]-Cap.jpg

A supercapacitor is an electrochemical device which stores and releases electricity like a battery, but instead of storing as chemical energy, it stores in the electric field.

THE [P]-CAP

One of the supercapacitor advantages is it can be charged in a few seconds instead of hours like a battery. Generally, supercapacitors are also known to have long operational lifetimes compared to batteries, with minimal change in performance.

 

However, current supercapacitors still require higher energy density, they can be expensive to fabricate, are rigid, have a poor working-temperature range and use a liquid electrolyte soaked separator.

•Battery Health: By offloading the high-power demands (like quick ascents or bursts for stabilization) to the supercapacitors, the battery maintains a more constant and lower discharge rate and preventing battery overheating and extending battery life, which can help extend its life .

•

•Power Efficiency: Supercapacitors are more efficient at handling rapid charge and discharge cycles than batteries. They can deliver necessary power faster, without the significant energy loss for peak demands such as sudden ascents or payload delivery, crucial for defense and commercial drone maneuvers.

•

•Adaptability: Designed for seamless integration our supercapacitors boast a customizable form factor designed to preserve the aerodynamics of drones, while their reduced weight and compact size enable space optimization, granting design flexibility and ensuring easy installation for immediate improvement in system performance.

SUPERCAPACITOR INTEGRATION

Super Capacitor Bank:

  • Provides high-power density energy storage.

  • Releases energy quickly when required by high-demand conditions.

Recharges any time there is not a high power demand and the voltage of the bank is low. This will be determined by the voltage sensor and the microcontroller.
Voltage Sensor:

  • Monitors the nodal voltage at the supercapacitor bank's direct output (node before DC-to-DC converter).

  • Ensures real-time tracking of the supercapacitor’s charge level based on its current output voltage.

DC-DC Converter:

  • Adjusts the supercapacitor output to the appropriate voltage for the drone's systems.

  • Ensures consistent power supply regardless of the supercapacitor’s current voltage.

Current Sensor:

  • Measures the current draw of the drone's power system.

  • Feeds data to the microcontroller for power demand analysis.

Microcontroller:

  • Acts as the central processing unit of the power management system.

  • Processes input from the voltage and current sensors.

  • Decide when to switch between the supercapacitor bank and the main battery based on power demand and the Capacitor Bank's charge level.

Power Switching Mechanism:

  • Executes the microcontroller’s commands to switch power sources.

  • The power switching mechanism  transistor-based, but we will see based on the power demands.

Battery (Primary Power Source):

  • Provides the primary energy storage for sustained flight.

  • Recharged as necessary when the drone is not in use.

Reduced Maintenance: By adding supercapacitors to work in parallel with battery systems, there is an increase in performance while reducing the stress on the battery. Therefore, we can visualize in figure 1 a lower cost to the green graph line ( supercapacitor integration system) that represents the maintenance cost of drone power systems versus the orange line (cost of system by itself). The supercapacitor integration offers a reduction in maintenance costs of approximately 25%.

•

Increased Battery Performance: Due to the supercapacitor integration, the battery system can rely on the supercapacitor for high power demands, which reduces the stress on the battery. The simulations show a battery performance increase when working in parallel with supercapacitors over a high number of cycles. This leads to a sustained longer flight time the battery is able to withstand over the number of years or cycles. Figure 2 shows a simulation of the amount of time the battery is able to perform across the number of battery life cycles of systems with and without supercapacitor integration.

Figures 1 and 2 are estimations based on simulation calculations.
