How much to charge a Lexus RZ?
A typical full home charge for a Lexus RZ 450e costs about $9–$12 in the United States at average residential electricity rates, with a per-mile cost around 4–8 cents. Public DC fast charging can cost more, usually ranging from around 0.30–0.50 USD per kilowatt-hour (kWh) or higher, often with additional session fees. These numbers vary by region, charging method, and network.
What affects charging costs
Charging costs depend on several factors beyond just the sticker price of electricity. Understanding these can help you budget for daily driving or road trips.
- Electricity price per kWh (home rates vs. public networks)
- Battery size and usable capacity of the RZ 450e (roughly 64 kWh usable out of about 71 kWh gross)
- Charging method (home Level 2 AC vs. DC fast charging)
- Charging efficiency and energy losses from wall to battery
- Time-of-use rates and incentives offered by utilities
- Networks’ pricing models (per kWh vs. per minute) and any idle or membership fees
Costs are driven by how much electricity you use (kWh) and the local price of electricity.
In practice, the mix of where you charge and when you charge has a big impact on the total cost. Night-time rates and membership plans can substantially lower what you pay over a month.
Estimating home charging costs for the Lexus RZ
For most owners charging at home, the math is straightforward: multiply the usable battery capacity by the electricity rate, then adjust for charging efficiency.
- Identify usable battery capacity: about 64 kWh usable for the Lexus RZ 450e.
- Check your local residential electricity rate (for example, roughly 12–20+ cents per kWh depending on state and utility).
- Compute the cost of a full charge: 64 kWh × rate. At 15 cents/kWh, a full charge costs about $9.60; at 20 cents/kWh, about $12.80.
- Estimate daily or weekly costs based on your driving: if you drive 40 miles per day and consume about 0.32 kWh per mile, you’d use roughly 12.8 kWh/day, costing about $1.92 at 15 cents/kWh.
- Consider time-of-use savings and utility incentives that shift charging to off-peak hours.
Because home charging is typically the most economical option, many owners plan to recharge overnight or during off-peak periods to minimize costs while ensuring plenty of range for daily use or trips.
Charging at public stations: what to expect
Public charging adds variability in price, but it’s essential for long trips or when you don’t have access to home charging.
- Price per kWh on DC fast networks (e.g., Electrify America, EVgo, ChargePoint) often falls in the 0.20–0.50 USD per kWh range, with higher rates at peak times or on certain stations.
- Some networks use per-minute pricing for DC fast charging, with rates that vary by speed tier and membership level.
- Many networks charge a small per-session or idle-fee if the vehicle remains plugged in after charging completes.
- Membership plans or bundled pricing can reduce per-kWh costs for frequent users.
Public charging costs depend on network pricing and charging speed.
For a Lexus RZ 450e, which supports DC fast charging up to about 150 kW, a typical 20–80% fill on a highway trip can still be efficient, but costs will be higher than home charging, especially if you rely on fast-charging stops for convenience rather than necessity.
Example pricing scenarios
These scenarios illustrate how the costs can stack up in real-world use. Actual prices will depend on your location and chosen networks.
- Home charging, typical residential rate (about 15¢/kWh): Full charge ~ $9.60; daily use of 40 miles ~ $1.92.
- Public DC fast charging on a road trip (0.30–0.50 $/kWh, plus occasional idle fees): 20–80% fill may require roughly 15–30 kWh, costing around $4.50–$15 depending on the station.
- Mixed use with off-peak home charging plus occasional DC fast charging: Average monthly cost can be kept modest if most charging occurs at home and fast charging is reserved for trips.
These examples show why many drivers prefer home charging as the baseline and treat public charging as a premium option for longer trips or urgent topping up.
Summary
Charging a Lexus RZ 450e is most economical at home, where a full charge costs roughly $9–$12 at typical U.S. electricity rates, translating to about 4–8 cents per mile. Public DC fast charging adds cost and complexity, with pricing that varies widely by network, sometimes 0.20–0.50 per kWh and occasional session or idle fees. To estimate your own costs, use the RZ’s usable battery capacity (about 64 kWh), your local rate, and your driving patterns, and consider time-of-use plans and membership options to maximize savings.
In the end, budgeting for the Lexus RZ's charging is about understanding where and when you charge, not just how much the electricity costs. With thoughtful planning, EV charging can be predictable and affordable, whether you’re commuting daily or taking long weekend road trips.
Can I charge my Lexus RZ at a Tesla charging station?
Yes, the Lexus RZ can use Tesla chargers, but the method depends on the model year. The 2026 and newer models have a native North American Charging Standard (NACS) port and can connect directly. Owners of 2023-2025 RZ models will need a Tesla-to-CCS adapter to access certain Supercharger stations.
For 2026 Lexus RZ models
- Direct connection: The 2026 RZ comes equipped with a NACS port, so no adapter is needed to use Tesla Superchargers.
- Plug & Charge: These models will also feature Plug & Charge capability for a seamless charging experience.
For 2023-2025 Lexus RZ models
- Adapter required: You will need a Tesla-to-CCS1 adapter to use many Tesla Superchargers.
- Adapter distribution: Lexus has stated that owners of older models will be offered adapters.
- Charging station compatibility: You must use a Tesla Supercharger that has been opened to non-Tesla EVs and has the necessary adapter (like the Magic Dock).
Important considerations
- Charging access: The Lexus app can help locate compatible charging stations.
- Physical access: Some older Tesla chargers may have cables that are too short to reach the RZ, requiring you to park strategically.
- Payment: Payment for charging at these stations can often be handled through the Tesla or Lexus app, depending on the specific station and setup.

How many kWh does it take to charge a Lexus RZ450e?
To get the shortest home charging time for the Lexus RZ450e, an 11kW AC charger would be needed. However, depending on your existing power supply and/or charging needs, it may only be practicable to fit a lower rated EVSE.
Is it cheaper to charge an electric car or buy gas?
Yes, it is generally cheaper to charge an electric car than to buy gas, especially when charging at home. Home charging can be up to 3 to 4 times cheaper than fueling a gas-powered car for the same distance traveled. While public charging is more expensive than home charging, it is still often cheaper than gas, particularly when factoring in the cost per mile.
Factors affecting cost
- Home charging: This is typically the cheapest option, as it uses your residential electricity rates.
- Public charging: Costs vary depending on the charger type, location, and network pricing, but are usually more expensive than home charging.
- Gas prices: Fluctuate and are generally higher than the cost of electricity per mile for EVs.
- EV and gas car efficiency: The cost comparison can depend on the specific models, as more efficient cars require less fuel or energy to travel the same distance.
Examples
- A sedan might save about $800$ 800$800 per year by switching to an electric vehicle, with charging costing about 5 cents per mile compared to 11 cents per mile for a gas-powered sedan.
- It could cost around $15.50$ 15.50$15.50 to fully charge a Nissan Leaf versus about $74$ 74$74 to fill up a comparable Honda Civic.
Summary
- Charging an electric car is cheaper than buying gas, especially if you charge at home.
- Home charging is the most cost-effective method, while public charging has a higher cost but is still often cheaper than gas.
- The total cost depends on local electricity and gas prices, the specific electric and gas vehicles being compared, and charging habits.
