Removed and replaced word by word to the other blog, meaning this blog from the other blog. I hope that's clear.
8:00 AM:
It has been something of a disappointment to read that electric vehicles are so heavy. Surely, there is a way to make them more light weight. So I tried asking AI a few questions on the matter...
Answer:
The text doesn't provide a direct answer to the amount of joules of energy that an ultracapacitor can hold. However, it mentions that ultracapacitors store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors.
To give you a better estimate, let's assume the energy stored in an electrolytic capacitor is around 1 Wh/kg (watt-hour per kilogram). Then, an ultracapacitor with the same mass could store between 10 Wh/kg and 100 Wh/kg.
To convert watt-hours to joules, we multiply by 3600 (since 1 Wh = 3600 J). So, an ultracapacitor with a mass of 1 kg could store between 36,000 J and 360,000 J.
Question to the LEO AI: Why can't Ultracapacitors be used instead of batteries?
Answer:
Ultracapacitors cannot serve as the propulsion battery in electric vehicles (EVs) because they lack the storage capacity. They can store a significant amount of energy, but it is not enough to power an EV for an extended period. Ultracapacitors are better suited for applications that require quick bursts of energy, such as:
* Regenerative braking in EVs (where they can help recover kinetic energy)
* Powering low-voltage systems, such as:
+ Instrumentation panels
+ Entertainment systems
+ LED lighting
+ Sensors
In these applications, ultracapacitors can provide a reliable and efficient source of power for short periods, but they are not a replacement for batteries in terms of long-term energy storage.
Comment:
Still not satisfied with this... I think that ultracapacitors MIGHT be more useful than is commonly thought. But I don't know enough to know why it is commonly thought and why it may be wrong ( in my opinion). Maybe I'm just talking out my ass, or maybe I'm on to something.
9:50 AM:
A few more questions, then!
Question: What is the measurement of capacity for capacitors?
Answer:
The measurement of capacity for capacitors is typically expressed in units of **Farads (F)**. However, capacitors are often available in smaller values, such as microfarads (μF), nanofarads (nF), or even picofarads (pF).
If you need more information on capacitor values or how they're used in circuits, let me know and I'd be happy to elaborate.
Question: How is a farad calculated or determined?
Answer: A **Farad (F)** is a unit of capacitance, calculated using the formula:
C = Q / V
Where: - C is the capacitance in Farads (F)
- Q is the charge in Coulombs (C)
- V is the voltage across the capacitor in Volts (V)
To determine the capacitance of a capacitor, you can use the following formula:[see note (1) below ]
Question: Is there a relationship between colulombs and amps?
Answer:
**Yes**, there is a relationship between Coulombs (C) and Amps (A).
The relationship is based on the definition of electric current:
I = Q / t
Where: - I is the current in Amps (A)
- Q is the charge in Coulombs (C)
- t is the time in seconds (s)
This means that 1 Ampere (A) is equal to 1 Coulomb (C) per second.
In other words, if you know the charge (in Coulombs) and the time (in seconds), you can calculate the current (in Amps).
It's getting there...
2:45 PM: It may be that the number of ultra-capacitors can be optimized as well as the other components to yield the lightest weight configuration. But that is a bridge too far for yours truly, but I can always speculate a bit. With that, the last question:
How much would a 500 F ultracapacitor weigh?
The weight of a 500F ultracapacitor can vary depending on the specific type, size, and manufacturer. However, a common type of ultracapacitor, called an Electric Double Layer Capacitor (EDLC), typically weighs between 1-3 kg (2.2-6.6 lbs) for a 500F rating.
Here's a rough breakdown of the weight of different types of ultracapacitors:
* EDLC (500F): 1-3 kg (2.2-6.6 lbs)
* Hybrid Ultracapacitor (500F): 0.5-2 kg (1.1-4.4 lbs)
* Lithium-Ion Ultracapacitor (500F): 0.2-1 kg (0.44-2.2 lbs)
Please note that these are rough estimates and actual weights may vary depending on the specific product and manufacturer.
Comment:
You may need about 20 units to give you enough acceleration for most cases. That's about as good as I can think it up based upon what I can figure. The actual number may be more or less, and by a significant margin. I'm no expert at this.
This is still a considerable amount of weight. The battery isn't figured in, nor the fuel cell. Then there's the machinery needed to handle to fuel. That won't be light weight. It may well be that battery powered vehicles will always be too heavy unless they come up with a miracle solution.
Note (1): C = (C1 \* C2) / (C1 + C2)
Where:
- C1 and C2 are the capacitances of two capacitors in series or in parallel.
However, this formula requires knowledge of the individual capacitances. If you have a capacitor and need to measure its capacitance, you can use a multimeter or a capacitance meter.
If you need more information on how to measure or calculate capacitance, I'd be happy to provide more details or point you in the right direction.
