Methodology
How the estimate is calculated
Monthly battery energy equals miles driven multiplied by vehicle electricity consumption. Charging loss converts that value into estimated wall energy.
The bill estimate applies the entered per-kWh rate and any EV-specific monthly fee.
Important assumptions
Use the electricity rate that applies when the EV charges.
The estimate does not model tiered rates, demand charges, or unrelated household electricity use.
Common questions
What to know about this estimate
Does this include my existing household electricity use?
No. It estimates the additional energy associated with EV charging.
What if my utility has time-of-use pricing?
Use the time-of-use calculator to model how much charging occurs at each rate.
City Council still has to approve the closure. Raincross Gazette reports RPU received 219 applications but only 30 completed installation and inspection, while the utility’s current process requires a separate meter, panel and clearance checks, permitting and final inspection.
Schneider says its hardwired SmartAmp models need no separate external energy monitor; UL 3141 can simplify load calculations where local authorities accept it, but managed charging does not guarantee every home can skip a panel or service upgrade.
Canada’s fuel rules do not set the 10¢ rate: other current private programs already advertise 10¢/kWh, and Kia’s live page warns its reward can change or vary even though its release describes a three-year subscription.
