Toyota bZ4X charging cost with SDG&E in California

Using CalcuRiver’s current verified SDG&E EV-TOU-5 schedule, a recurring 11 p.m.–7 a.m. every day in 2026-10 charging window resolves to a duration-weighted 20.72¢/kWh. At 1,000 miles/month, Toyota bZ4X is estimated at $58.68 in wall electricity — $36.50 less than the California statewide-average result.

Boundary. This is a marginal charging-energy estimate. Fixed charges, taxes, riders and account-specific adjustments remain separate unless explicitly modeled.

What is being calculated?

Vehicle efficiency3.53 mi/kWh
Utility reference20.72¢ scheduled effective
Battery referencenot published in verified set

MPGe-backed vehicles use the EPA 33.7 kWh/gallon-equivalent conversion; EPA says the MPGe label value already includes charging losses, so CalcuRiver does not add another default loss. Where a manufacturer source gives usable battery and EPA-estimated range but not MPGe, the reference efficiency is battery ÷ range and a 10% wall-loss assumption is applied by default.

cost = miles × 0.283193 kWh/mile × 1.00 × $0.20722/kWh

Utility reference ≠ complete bill. This estimate applies the encoded marginal energy reference for SDG&E. Fixed charges, taxes, account-specific riders, eligibility rules and unmodeled bill components remain separate unless the tariff engine explicitly models them.
