PURPOSE
Assess a plug-in hybrid using realistic charging frequency and trip lengths.

HOW TO USE
Open this file in a text editor and save a private copy. Fill each prompt with observations and a source or date where relevant. Use “unknown” for missing evidence, “not applicable” when a field does not apply, and record the next action. Follow the vehicle manual and product instructions; this worksheet is a planning record, not a repair procedure or safety certification. Keep units with measurements and identify hypothetical numbers. Do not post VINs, account details or personal documents publicly.

1. Exact model, year, operating modes and owner-manual link
Response:
Evidence / date:
Next action:

2. Seven-day log: each day’s miles, departure charge, charging location and completed session
Response:
Evidence / date:
Next action:

3. Typical miles between charges; long-trip miles; missed-charge scenario
Response:
Evidence / date:
Next action:

4. Label electric range, purchased kWh/100 miles, gasoline-mode MPG and blended fuel if shown
Response:
Evidence / date:
Next action:

5. Cost = purchased kWh × electricity rate + gallons × fuel price + charging fees; use the same observation period
Response:
Evidence / date:
Next action:

6. Hypothetical check: 300 total miles; 150 electric miles × 30/100 = 45 kWh; 150 gasoline miles / 40 = 3.75 gal; 45 × $0.20 + 3.75 × $3.60 = $22.50. No-charge example: 300/40 × $3.60 = $27.00. Assumes no blended gasoline and is not a model forecast.
Response:
Evidence / date:

7. Charging time, connector, approved equipment and demonstration observations
Response:
Evidence / date:
Next action:

8. Battery and engine inspection evidence; maintenance requirements; final comparison with HEV and BEV
Response:
Evidence / date:
Next action:
