The Lexus RZ is a battery-electric large luxury SUV, so charging is central to day-to-day ownership. In the UK, it uses the familiar Type 2 connection for AC charging and CCS2 for DC rapid charging, making it compatible with the majority of home wallboxes, workplace chargers and public rapid chargers.
One important point for RZ owners is that the UK range has changed significantly. Earlier RZ 300e and RZ 450e cars used a 71.4 kWh battery and different AC charging capability. The refreshed MY26 UK range, including the RZ 350e, RZ 500e and RZ 550e F SPORT, uses a larger 77 kWh gross battery and has a 22 kW AC onboard charger. That makes it worth checking which RZ you own before choosing a charging cable or estimating charging times.
Lexus RZ Battery and Charging Specifications
UK Lexus RZ models are battery-electric vehicles only; the RZ is not a plug-in hybrid. For AC charging, UK and European cars use a Type 2 socket. For rapid charging, they use the CCS2 / CCS Combo 2 connector. On current MY26 models, EV Database lists the charge port location as the left-front side of the vehicle.
| Model context | Battery | AC charging | DC rapid charging | Connector |
|---|---|---|---|---|
| Current MY26 RZ 350e, RZ 500e and RZ 550e F SPORT | 77 kWh gross; around 72 kWh usable according to EV Database | Up to 22 kW AC, where three-phase 32A charging is available | Up to 150 kW; 10-80% in around 30 minutes | Type 2 AC and CCS2 DC |
| Earlier RZ 300e and RZ 450e | 71.4 kWh gross; EV Database lists around 64 kWh usable for the RZ 450e | Up to 11 kW AC in Lexus UK technical data | CCS rapid charging supported; check model-year data for exact expectations | Type 2 AC and CCS2 DC |
Battery Options
The current MY26 Lexus RZ range uses a 77 kWh gross lithium-ion battery across the RZ 350e, RZ 500e and RZ 550e F SPORT. EV Database lists usable capacity at around 72 kWh for these current models. Usable capacity is the amount of battery energy normally available for driving, with a buffer retained by the vehicle’s battery management system.
Earlier UK RZ 300e and RZ 450e models are different. Lexus UK technical data for the previous model lists a 71.4 kWh battery, and EV Database lists 64.0 kWh usable capacity for the RZ 450e. Because battery size and charging hardware differ, it is best not to apply current MY26 charging figures automatically to pre-facelift cars.
AC Charging Speed
AC charging is what you use with most home wallboxes, many workplace chargers and slower public charge points. The current MY26 Lexus RZ has a 22 kW AC onboard charger. This is a strong specification, but it only delivers its full benefit when the charge point can supply three-phase 32A power and the cable is rated appropriately.
Most UK homes have a single-phase electrical supply, and a 7.4 kW wallbox is the practical maximum for many domestic installations. On a current RZ, EV Database estimates a full AC charge at 7.4 kW at around 11 hours 30 minutes. Lexus quotes about 3 hours 30 minutes for 10-100% AC charging on current models, but that assumes access to suitable 22 kW three-phase AC charging.
For older RZ 300e and RZ 450e models, Lexus UK April 2025 technical data lists an 11 kW onboard AC charger. In that context, a 7 kW single-phase charge is listed at about 10 hours 15 minutes, while 11 kW three-phase charging is around 6 hours 30 minutes. This is why model-year matters when comparing charging times.
DC Rapid Charging Speed
DC rapid charging bypasses the car’s AC onboard charger and feeds high-power DC energy directly to the battery. For the current MY26 Lexus RZ, Lexus technical information lists a maximum DC charging rate of 150 kW and a 10-80% rapid charge time of around 30 minutes. Some retail material may show slightly different wording for certain grades, but around 30 minutes is the sensible figure to use.
To reach the RZ’s peak DC capability, use a CCS rapid charger rated at 150 kW or higher. The car will not hold its peak rate all the way from 10% to 80%; charging speed naturally tapers as the battery fills, particularly above 80%. For long journeys, shorter 10-80% charging stops are usually more efficient than waiting for a rapid charger to fill the battery to 100%.
Range and Efficiency
Official WLTP range varies significantly by version and wheel size. For the current MY26 range, Lexus technical data lists the RZ 350e at up to 353 miles on 18-inch wheels and up to 316 miles on 20-inch wheels. The RZ 500e is listed at up to 311 miles on 18-inch wheels and up to 283 miles on 20-inch wheels. The RZ 550e F SPORT is listed at around 280 miles in Lexus technical specification data, while UK retail material shows grade ranges in a similar area.
Real-world range will usually be lower than the best WLTP figures, especially in cold weather, at motorway speeds or with larger wheels. EV Database estimates around 245 miles of real-world range for the RZ 350e and RZ 500e, and around 240 miles for the RZ 550e F SPORT. Driving style, temperature, tyre choice, road speed, passenger load and use of climate control all influence the result.
Charging at Home
For most UK RZ drivers, a dedicated home wallbox is the easiest and most cost-effective way to charge. A 7.4 kW single-phase wallbox will typically add a substantial amount of range overnight, even though it will not use the full 22 kW AC capability of a current MY26 RZ. If your property has a suitable three-phase supply, a compatible 22 kW wallbox may be possible, but this should not be assumed for a normal UK driveway.
When choosing a cable for home and public AC charging, match it to the charging you expect to use. For a current MY26 RZ, a Type 2 cable rated for three-phase 32A is required to make full use of 22 kW AC charging on compatible three-phase posts. If you only ever use a 7.4 kW home wallbox, a single-phase Type 2 cable may work for that use, but a three-phase cable gives broader compatibility with faster AC posts at workplaces, hotels and public destinations.
A 3-pin charger is generally best suited as a backup or occasional charging solution, but can be used regularly if a qualified electrician has confirmed the socket and electrical installation are suitable for sustained EV charging. Because the RZ has a large battery, 3-pin charging will be slow compared with a wallbox.
Public Charging
Public AC charging is useful when parked for several hours, such as at work, hotels, shopping centres or longer-stay car parks. Current MY26 RZ models can take advantage of 22 kW AC posts where they are available, provided you use a suitable three-phase Type 2 cable. Earlier RZ 300e and RZ 450e models are limited by their 11 kW AC onboard charger, so they will not charge at 22 kW AC even if plugged into a 22 kW post.
For motorway and long-distance travel, CCS rapid charging is the key. Look for 150 kW or higher DC chargers where possible, pre-plan charging stops, and avoid arriving with a very high state of charge if you want the fastest charging session. Charging from roughly 10% to 80% is usually the best balance of speed and range gained.
Vehicle-Specific Features
Current MY26 Lexus RZ models are listed with a standard heat pump, which can help reduce the energy demand of cabin heating compared with more basic heating systems. Real-world benefit depends on temperature and usage, but it is a useful feature for UK winter driving.
Battery preconditioning is also available on current MY26 cars. Lexus UK media material states that preconditioning can operate automatically when a charging location is set in the navigation, or manually where available. This is especially useful before DC rapid charging in cold weather, as a battery at a suitable temperature can accept higher charging power more readily.
The Lexus Link+ app can be used to monitor charge level and range, schedule or start and stop charging, and support remote cabin preconditioning. EV Database lists V2L, V2H and V2G as not supported for MY26 RZ models, so owners should not assume the car can export power to appliances, a home or the grid.
Charging Tips
- Check your exact model. A current RZ 350e, RZ 500e or RZ 550e F SPORT has different AC charging capability from an earlier RZ 300e or RZ 450e.
- Use the right Type 2 cable. For current MY26 cars, choose a three-phase 32A Type 2 cable if you want to use 22 kW AC posts.
- Do not expect 22 kW from most homes. Many UK domestic wallboxes are single-phase 7.4 kW.
- Rapid charge in the fast part of the curve. On long trips, charging from about 10-80% is normally quicker overall than waiting for 100%.
- Use preconditioning before rapid charging. On current MY26 models, set the rapid charger in the navigation or use the manual setting where available.
- Schedule overnight charging. If your electricity tariff offers cheaper off-peak rates, the Lexus Link+ app and wallbox scheduling can help reduce costs.
Frequently Asked Questions
What charging cable does the Lexus RZ use?
UK Lexus RZ models use a Type 2 cable for AC charging. For DC rapid charging, the public charger has a tethered CCS2 connector, so you do not normally use your own cable.
Can the Lexus RZ charge at 22 kW AC?
Current MY26 RZ 350e, RZ 500e and RZ 550e F SPORT models have a 22 kW AC onboard charger. Earlier RZ 300e and RZ 450e models should not be assumed to have this capability; Lexus UK technical data for the previous car lists 11 kW AC charging.
Can I get 22 kW charging at home?
Only if your property has a suitable three-phase supply and a compatible 22 kW wallbox installation. Most UK homes are single-phase, where a 7.4 kW wallbox is more typical.
How long does rapid charging take?
For current MY26 models, Lexus technical data lists up to 150 kW DC rapid charging and a 10-80% time of around 30 minutes, provided charger conditions and battery temperature are suitable.
Should I charge the Lexus RZ to 100% every day?
For everyday use, many EV drivers set a lower daily charge limit and reserve 100% for longer journeys. Always follow the guidance in the vehicle handbook and charging menu for your exact model.
What This Means for Drivers
The Lexus RZ is straightforward to charge in the UK, but the best setup depends on which version you own. Current MY26 RZ models benefit from a larger battery and a 22 kW AC onboard charger, making a three-phase 32A Type 2 cable worthwhile if you regularly use workplace or public 22 kW AC posts. At home, however, most owners will still charge at up to 7.4 kW from a single-phase wallbox.
Earlier RZ 300e and RZ 450e models remain fully compatible with Type 2 AC and CCS2 rapid charging, but their battery and AC charging specifications differ from the latest range. For any RZ, the simplest approach is to use a dedicated wallbox for regular home charging, a suitable Type 2 cable for untethered AC posts, and CCS rapid chargers for longer journeys.
