Fast charging an electric vehicle (EV) at a DC fast charging station (Level 3) typically costs between $0.25 to $0.80 per kWh, though some stations may use flat fees per session. The actual cost can vary significantly depending on location, charging network, and the specific charger used. For example, Electrify America charges $0.48/kWh for DC fast charging, while EVgo's prices vary by time of day, ranging from $0.36 to $0.63 per kWh in California. 

Here's how to calculate the estimated kWh per gallon of diesel

• 1. Energy content of diesel: A gallon of diesel fuel contains approximately 137,380 BTU, according to the U.S. Energy Information Administration (EIA).

• 2. Convert BTU to kWh: 1 kilowatt-hour (kWh) is equivalent to 3,412 BTU.

  • Calculation: 137,380 BTU / 3,412 BTU/kWh ≈ 40.26 kWh.

• 3. Account for generator efficiency: Diesel generators convert only a portion of the energy in the fuel into electricity, with the rest lost as heat and friction. Typical efficiencies range from 35% to 50%, depending on the generator's design, load, and maintenance.

Do the Math

Calculation 

Tradition Generator 30% efficiency): 40.26 kWh * 0.30 ≈ 12.08 kWh  * $0.28 to $0.80 per kWh = $3.38 to $9.66 per gallon Validation

PHIMS Generator 90% efficiency): 40.26 kWh * 0.90 ≈ 36.23 kWh  * $0.28 to $0.80 per kWh = $10.14 to $28.98 per gallon 

💡 1. Keep Customers On-Site with EV Charging

• Oil companies already own prime real estate and traffic flow.
  
  

• Instead of losing EV customers, they offer fast charging on-site using fuel converted into electricity via PHIMS.
  
  

• More time on site = more profit from food, coffee, car washes, and upsells.
  
  

⚡ 2. Avoid Utility Losses — Generate Power Directly

• Traditional electricity loses 60%  or more and 22.5% in transmission = 82.5%.
  
  

• PHIMS converts fuel directly into electricity on-site with 90% efficiency.  see Validation
  
  

• This means oil companies sell more energy per gallon of fuel.
  
  

🔋 3. Skip the Grid — No Delays or Power Bottlenecks

• No need to wait for expensive utility upgrades.
  
  

• PHIMS provides instant, high surge output (20x boost) to support fast EV charging. Validation
  Faster setup = faster profit.
  
  

🛠️ 4. Low Maintenance, No Batteries

• PHIMS uses supercapacitors instead of batteries: no fire risks, no rare minerals, no recycling hassles.
  Fewer parts = fewer costs.
  
  

💰 5. New Revenue Without Cannibalizing Fuel Sales

• Every gallon of fuel still sold—but now it’s also used to charge EVs.
  
  

• Two profits from one fuel sale:

  • Once at the pump

  • Again through PHIMS electricity for EVs
    
    

🚀 Bonus: Government Grants or Carbon Credits

Because PHIMS increases efficiency and cuts transmission losses, oil companies can qualify for clean energy credits or grants, improving margins even further.
