What this calculator doesn't do is account for the capacity that an automaker might be guarding to protect the battery. For instance, even though a battery has a given capacity, the automaker may not allow the entire capacity to be used in order to protect the batteries from damage via over-discharge.
If you find errors or have suggestions, please let me know! If you save the spreadsheet as an Excel Spreadsheet, you will be able to see the formulas that I used.
- The Nissan Leaf and Chevy Volt only charges at 3.3kW/h at Level 2 (220V), so you need to enter 15A for the charging current to see more accurate estimates. The Coda Sedan charges at 6.6 kW/h, so you would enter 30A for the charging current.
- The Chevy Volt has a 16 kW/h battery, but limits the use (via software) between 30% and 85% of capacity to prolong battery life. Therefore you should figure to recharge only 8.8 kW/h.
