- Why does battery recharge cost vary by state?
- Electricity prices vary significantly by state due to generation mix, transmission costs, regulations, and demand. Higher state rates mean higher recharge costs for the same battery capacity.
- Does charging efficiency affect battery recharge cost?
- Yes. Real-world charging typically has 5–15% losses (inverter, heat, etc.). At 90% efficiency, you draw about 11% more electricity from the grid than the battery stores. Our efficiency-adjusted estimates use a 90% charging efficiency factor.
