Localized EV data asset
Charging cost is not one fixed number. It changes with your Lexus RZ version, the percentage of battery you add, charging losses and—especially in Southern California—the time-of-use electricity rate when you plug in.
Direct answer
At SCE’s currently published 26¢/kWh summer off-peak TOU-D-PRIME rate, a theoretical 0–100% refill of a 74.69-kWh RZ battery works out to about $21.58 in energy using a 90% charging-efficiency planning assumption. A 10–80% session works out to about $15.10 under the same assumptions. These are planning estimates—not a utility-bill quote—and exclude the $0.79/day base service charge, taxes, fees and any different generation-provider rates.

Estimated output
Planning tool only. Real charging efficiency, utility billing, range and public-charging prices vary. SCE rates shown are published TOU-D-PRIME energy rates reviewed August 27, 2026. Fixed daily charges, taxes, fees and different generation-provider charges are excluded.
Why time matters
SCE notes that these rates reflect customers receiving both delivery and generation from SCE. If your electricity generation comes from a Community Choice Aggregator or another provider, your actual generation rate can differ. Always use your bill for a household-specific estimate.
2026 charging hardware
The 2026 RZ adopts the SAE J3400 North American Charging System port, broadening compatible charging options.
Lexus increased the onboard AC charger capacity for Level 1 and Level 2 charging compared with the prior model year.
Under ideal DC fast-charging conditions. Weather, charger output, state of charge and battery temperature can change the result.
Charging FAQ
It depends on the RZ model, how much battery you add, your electricity rate and charging losses. Using the published summer SCE TOU-D-PRIME off-peak rate of $0.26 per kWh and a 90% planning efficiency assumption, an RZ with a 74.69-kWh battery would use about $21.58 of energy for a theoretical 0% to 100% charge. The same energy added during the $0.59 per kWh summer weekday on-peak window would cost substantially more. Fixed charges, taxes and other bill components are not included.
Use the rate that actually applies to the energy used for charging on your utility bill. SCE TOU-D-PRIME presets are included as a local reference, but customers with a Community Choice Aggregator or other generation provider may have different generation charges.
Lexus states that under ideal conditions the 2026 RZ can charge from 10% to 80% in around 30 minutes using DC fast charging. Charging time varies with temperature, charger capability, battery state and other conditions.
Yes. The 2026 RZ uses the SAE J3400 North American Charging System charge port and also has an 11-kW onboard AC charger.
Not necessarily. Home cost depends on your utility rate and time of use, while public charging prices vary by network, location and session. Compare your actual rate before making a cost claim.
