The attachment shows cost to operate on a short around town trip in ev mode and compares to what it would cost in gas mode. I used a watt meter to measure kwh used for full recharge. (3.43 kwh). The cmax reading was 2.5 kwh. Possibly additional energy to cool battery while charging? Have Excel spreadsheet but not allowed to upload.

There are energy losses in charging the HVB.  Your losses appear to be 0.93/3.43 = 27% or your charging efficiency = 73% which I believe is in the ballpark using 120 VAC charger. IIRC, using 220 VAC  will get the charging efficiency up over 80% but at an additional cost of the 220 V charging station and installation.

 

The energy cost of an PHEV or EV is significantly less than an ICE vehicle   But, the overall benefits of a PHEV or EV are highly dependent on the cost premium of a PHEV or EV, electric rates, fuel prices, EV range, expected EV miles and so forth.
