The EX30 Single Motor Extended Range takes 28 minutes from 10 to 80 per cent on DC and about 6.6 hours at home on an 11 kW wallbox. At the US average rate a full charge is $13.29 – among the cheapest on this site – and running it costs $5.37 per 100 miles.
How long it takes to charge
| Where | Power | Time | What that is |
|---|---|---|---|
| Home, Level 1 | 1.4 kW | ≈ 50 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 | 9.4 hours | Empty to full, overnight |
| Home, Level 2 | 11.0 kW | 6.6 hours | Empty to full, overnight capped by the 11.0 kW onboard charger |
| Public DC, at its peak | 158 kW | 28 min | 10 to 80 per cent — the figure to compare cars on |
| Public DC station | 50 kW | ≈ 55 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 | $13.29 | $5.37 |
| Public DC fast charging | $0.48/kWh | $31.20 | $14.02 |
| 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 65.0 kWh usable and a full charge draws about 72.2 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 $725.33 of electricity charging at home, against $2,035.00 of petrol in the comparison car: a difference of $1,309.67 a year.
A small pack is a feature on this page
At 65 kWh usable the EX30 has one of the smallest batteries here — only the two 60 kWh rear-drive Teslas are smaller — and every number above follows from it. It fills fastest at home because there is less to fill. Its full charge is among the cheapest because you are buying less energy. Its 28-minute rapid window is competitive not because the car charges hard but because it does not have far to go.
The trade is range: 261 miles EPA and 365 km observed, the shortest of the group. If your driving is local and you charge at home, a small pack costs you almost nothing and saves you money every time you plug in. If it is not, this is the wrong car and the ranking on longest-range electric cars is the right page.
158 kW peak, reached at a 150 kW post
The EX30 peaks at 158 kW, so a 150 kW station is effectively its ceiling and a 350 kW one adds nothing. On a 50 kW post the wait roughly doubles to 55 minutes – still the shortest 50 kW figure here, again because the pack is small.
Why the peak number is a poor guide to any of this is set out in what a 10-80% charge time tells you.
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 29.2 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 | 20 h 17 min | 50 h 9 min | the EPA figure, measured at the wall |
| Home wallbox, Level 2 | 7.7 kW | 26 mi/h | 3 h 48 min | 9 h 23 min | the EPA figure, measured at the wall |
| Home wallbox, Level 2 | 11.0 kW | 38 mi/h | 2 h 39 min | 6 h 34 min | capped by the 11.0 kW onboard charger |
| Public DC station | 50 kW | 201 mi/h | 30 min | — | held back by the station (estimate) |
| Public DC station | 150 kW | 391 mi/h | 15 min | — | the car’s own 28-minute 10-80 curve is the limit |
| Public DC station | 350 kW | 391 mi/h | 15 min | — | the car’s own 28-minute 10-80 curve is the limit |
A Level 1 outlet adds about 5 miles an hour — 49 miles in a ten-hour overnight stop, enough for a commute and not for much else. A 7.7 kW wallbox raises that to 26 miles an hour, so 100 miles takes 3 h 48 min and the car is full from empty in 9 h 23 min. On DC the useful figure is 391 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 15 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 30 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 — Illinois, Indiana, Iowa, Kansas — and a 50-state table ranked cheapest first.
Where these numbers will mislead you
A cheap full charge is not a cheap mile. $13.29 fills it, but at 29.2 kWh per 100 miles the EX30 is only mid-table on cost per mile – about $725 a year. A small tank is cheap to fill and gets filled more often.
This is the Extended Range single motor. The standard-range EX30 uses a smaller LFP pack with different charging behaviour and different figures.
Frequently asked questions
How long does it take to charge a Volvo EX30?
About 28 minutes from 10 to 80 per cent on a 150 kW DC station, and roughly 6.6 hours from empty on an 11 kW home wallbox – about 9.4 hours on a 7.7 kW supply.
How much does it cost to charge a Volvo EX30?
About $13.29 for a full charge at the US average residential rate, beaten only by the two 60 kWh rear-drive Teslas, or $5.37 per 100 miles – roughly $725 a year against $2,034 of petrol.
Does the EX30 need a 350 kW charger?
No. It peaks at 158 kW and gets its full speed from a 150 kW post.
How many kWh does it take to fully charge a Volvo EX30?
The pack holds 65 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 72 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.
