The bZ4X AWD takes 28 minutes from 10 to 80 per cent on DC and about 7.0 hours at home on an 11 kW wallbox. At the US average rate a full charge is $14.11 and running it costs $5.15 per 100 miles – the fourth lowest here, behind the Ioniq 6, the Model 3 Long Range and the Model Y Long Range.
How long it takes to charge
| Where | Power | Time | What that is |
|---|---|---|---|
| Home, Level 1 | 1.4 kW | ≈ 53 hours est | Empty to full on a 120 V household outlet at 12 A — suited to daily top-ups; a full charge can take days |
| Home, Level 2 | 7.7 kW | 10.0 hours | Empty to full, overnight |
| Home, Level 2 | 11.0 kW | 7.0 hours | Empty to full, overnight capped by the 11.0 kW onboard charger |
| Public DC, at its peak | 150 kW | 28 min | 10 to 80 per cent — the figure to compare cars on |
| Public DC station | 50 kW | ≈ 58 min est | 10 to 80 per cent, held back by the station |
| Public DC station | 150 kW | ≈ 28 min | 10 to 80 per cent — the car reaches its own limit here, not the station |
| Public DC station | 350 kW | ≈ 28 min | 10 to 80 per cent — the car reaches its own limit here, not the station |
What it costs to charge
| Charging at | Rate | Full charge | Per 100 miles |
|---|---|---|---|
| Home | $0.184/kWh | $14.11 | $5.15 |
| Public DC fast charging | $0.48/kWh | $33.12 | $13.44 |
| A petrol car, for comparison | $4.07/gal | — | $15.07 |
Assumptions, all editable in the running-cost calculator: $0.184/kWh at home (EIA US residential average) and $0.48/kWh on public DC, against petrol at $4.07 a gallon and 27 mpg. The battery holds 69.0 kWh usable and a full charge draws about 76.7 kWh from the wall; on a pack this small the difference is a dollar or two, but it is real and it is in the numbers above. Rated consumption is wall-measured, so it is not adjusted again.
Over 13,500 miles a year — the US average — that is $695.52 of electricity charging at home, against $2,035.00 of petrol in the comparison car: a difference of $1,339.48 a year.
Cheap per mile, on the test
At 28 kWh per 100 miles the bZ4X is rated the eighth most efficient of the 36 EPA-rated cars on this site, and its cost per mile follows directly from that: about $695 a year over average US mileage against roughly $2,034 of petrol.
The rating and the road do not agree, though. The bZ4X is rated 516 km on WLTP and returns 375 km observed – a 27 per cent shortfall, among the widest gaps we have measured. The EPA number of 288 miles is the more honest one, which is the general pattern we found across the fleet and wrote up in EPA against WLTP.
150 kW peak, and the charger is never the problem
It peaks at 150 kW and hits its 28-minute window there, so a 350 kW station adds nothing. On a 50 kW post it takes 58 minutes. With a 69 kWh usable pack there is not much energy to move, which keeps even the slow case reasonable.
Where it stands against everything else is on fastest-charging electric cars.
Miles of range per hour, at every charger
The tables above answer “how long does a full charge take”. The question most drivers actually have at a plug is different: how much range goes in per hour, and how long until the next 100 miles are on the clock. This table answers that for every kind of charger, from a household 120-volt outlet to a 350 kW station, using the same figures as the rest of the page — the EPA’s 28.0 kWh per 100 miles, which is measured at the wall, and the measured 28-minute 10-80 per cent time. Rated range is used throughout; in winter, or at motorway speed, every row shrinks by the same proportion.
| Charger | Power at the car | Miles per hour | Add 100 mi | Empty to full | What sets the rate |
|---|---|---|---|---|---|
| Household outlet, Level 1 (120 V, 12 A) | 1.4 kW | 5 mi/h | 19 h 27 min | 53 h 14 min | the EPA figure, measured at the wall |
| Home wallbox, Level 2 | 7.7 kW | 28 mi/h | 3 h 38 min | 9 h 57 min | the EPA figure, measured at the wall |
| Home wallbox, Level 2 | 11.0 kW | 39 mi/h | 2 h 33 min | 6 h 58 min | capped by the 11.0 kW onboard charger |
| Public DC station | 50 kW | 209 mi/h | 29 min | — | held back by the station (estimate) |
| Public DC station | 150 kW | 432 mi/h | 14 min | — | the car’s own 28-minute 10-80 curve is the limit |
| Public DC station | 350 kW | 432 mi/h | 14 min | — | the car’s own 28-minute 10-80 curve is the limit |
A Level 1 outlet adds about 5 miles an hour — 51 miles in a ten-hour overnight stop, enough for a commute and not for much else. A 7.7 kW wallbox raises that to 28 miles an hour, so 100 miles takes 3 h 38 min and the car is full from empty in 9 h 57 min. On DC the useful figure is 432 miles an hour at a 150 kW post, and a 350 kW station does not raise it because the car’s own curve is the limit from 150 kW up — 100 miles in 14 min. The 50 kW row is the one to remember on a road trip: the station, not the car, sets the pace, and 100 miles takes 29 min.
The per-hour figures do not change with your electricity price, but the cost of every hour does: the residential rate runs from 13.11 cents a kWh in Nevada to 52.72 in Hawaii (EIA, June 2026). We publish the arithmetic for this car in every state — Florida, Georgia, Hawaii, Idaho — and a 50-state table ranked cheapest first.
Where these numbers will mislead you
Use the observed range, not the WLTP figure. The cost per 100 miles above is built on the EPA consumption number, which is measured at the wall and matches real driving far more closely than the WLTP range does.
This is the all-wheel-drive car. The front-wheel-drive bZ4X is lighter, more efficient and has different figures throughout.
Frequently asked questions
How long does it take to charge a Toyota bZ4X?
About 28 minutes from 10 to 80 per cent on a 150 kW DC station, and roughly 7.0 hours from empty on an 11 kW home wallbox – about 10 hours on a 7.7 kW supply.
How much does it cost to charge a Toyota bZ4X?
About $14.11 for a full charge at the US average residential rate, or $5.15 per 100 miles – roughly $695 a year against $2,034 of petrol.
Why is the bZ4X real-world range so much lower than claimed?
Its WLTP rating of 516 km is optimistic; observed driving returns about 375 km. The EPA rating of 288 miles is the figure to plan around.
How many kWh does it take to fully charge a Toyota bZ4X?
The pack holds 69 kWh usable, but you pay for what comes out of the wall, and AC charging is roughly 90 per cent efficient — so a full charge draws about 77 kWh. That is the figure your electricity bill sees, and it is why the full-charge cost above is higher than capacity multiplied by tariff would suggest.
The same arithmetic across every car on this site: how many kWh a full charge really takes, 7.7 kW against 11.5 kW at home, and what charging costs per month.
