Charging the median electric car at home in Mississippi costs about $52 a month at 14.88 cents per kilowatt-hour — the 12th cheapest of 51 states, and 19 per cent below the national average. Petrol over the same 1,125 miles costs $170, so the saving is $118 a month, $1,410 a year; on the public side 21 registered cars share each fast-charging plug, against 55 in the typical state.
Public fast charging in Mississippi
Mississippi has 99 public DC fast-charging sites with 345 plugs in the federal AFDC station locator (2026-09-16), for 7,200 battery-electric cars registered in the state at the end of 2025.
By the measure that matters on a Friday afternoon — cars divided by plugs — Mississippi is among the best-served states in the country: 21 registered EVs for every public fast-charging plug where the typical state manages 55 — 4th of 51. That is not a charger on every corner; it means the ones that exist are less likely to have a queue.
Nearly half of those sites stand alone: 45% of Mississippi fast-charging locations have exactly one plug, so an occupied or broken charger means driving on rather than waiting behind one car. The state averages 3.5 plugs per site.
Tesla is the largest network in Mississippi with 42% of the plugs (144 of 345), the rest split among the other operators — enough competition that price and reliability are not one company decision.
Which plug fits in Mississippi
The plug question in Mississippi has a clear answer: 88% of the sites carry CCS1, the connector on almost every non-Tesla EV sold in the US, against 25% carrying the Tesla NACS plug. A CCS car has the run of the state; a Tesla is at home on its own network and needs an adapter elsewhere.
| Connector | Sites in Mississippi | Share of sites | Cars that use it |
|---|---|---|---|
| CCS1 (J1772 Combo) | 87 | 88% | Almost every non-Tesla EV sold in the US |
| NACS / J3400 (Tesla) | 25 | 25% | Teslas, and other cars with an adapter where the site allows it |
| CHAdeMO | 31 | 31% | Older Nissan Leaf and Mitsubishi only |
31 sites keep a CHAdeMO plug (31%). Useful if you drive an older Leaf in Mississippi; irrelevant to everything else on this page, and the count falls every year as sites are refitted.
Public fast charging does not follow the residential rate. At a typical network price of $0.48 per kWh the median car costs $14.93 per 100 miles — 3.2 times what the same miles cost at home in Mississippi, and still under the $15.07 the petrol car spends on them. Anyone charging mostly in public in Mississippi should read the home column as optimistic by a factor of 3.2 — that multiple, not the state, is what decides whether the sums work. How long each car takes on a fast charger is on its charging page.
What electricity costs in Mississippi
The EIA published residential average for Mississippi is 14.88 cents per kWh (June 2026), against a US average of 18.34. That puts Mississippi at 12th of 51 states and DC, cheapest first — the cheaper half of the country. Put the Chevrolet Equinox EV FWD on that rate — the middle car of the 36 rated here, at 31.1 kWh per 100 miles — and it costs $4.63 per 100 miles, $52 a month, $625 a year.
Against a 27 mpg car at $4.07 a gallon, electricity stops being the cheaper fuel at about 48 cents per kWh. Mississippi is below that line by 33.59 cents, so the saving holds at the state-average rate before any overnight tariff is applied. It is an average across every household and every hour of the month: an overnight window beats it, a summer peak does not. The running-cost calculator takes your own tariff instead of the state’s.
Every EPA-rated car, charged at home in Mississippi
Efficiency is worth more in Mississippi than in most states: $70 a month separates the Lucid Air Pure RWD from the GMC Hummer EV Pickup 3X, and every car in the table still beats the $170 the petrol car burns through.

EPA combined ratings are measured at the socket, not at the battery, which is why these numbers are about a tenth higher than a pack-size calculation would give. That is the honest figure: it is what the meter in Mississippi records. The four cars without a US rating are in kilometres on the national page.
Mississippi against its neighbours
Louisiana, Arkansas, Tennessee are cheaper than Mississippi; Alabama is dearer. The monthly column is the Chevrolet Equinox EV FWD in every row, which makes the border differences directly comparable — $5 a month separates Mississippi from its cheapest neighbour.
| State | Cents / kWh | Rank | Chevrolet Equinox EV FWD / month | Fast plugs | EVs per plug |
|---|---|---|---|---|---|
| Louisiana | 13.49 | 4th | $47 | 410 | 55 |
| Tennessee | 14.07 | 5th | $49 | 1,024 | 54 |
| Arkansas | 14.12 | 7th | $49 | 287 | 43 |
| Mississippi | 14.88 | 12th | $52 | 345 | 21 |
| Alabama | 16.40 | 28th | $57 | 891 | 27 |
How long the charge itself takes does not change with the state, only what it costs: the Hyundai Ioniq 5 charging time, Hyundai Ioniq 6 charging time and Kia EV6 charging time are 18, 17 and 17 minutes from 10 to 80 per cent wherever you plug in, and each of those pages runs the same cost arithmetic as this one at the national average rate rather than Mississippi’s.
Frequently asked questions
How much does it cost to charge an electric car in Mississippi?
About $4.63 per 100 miles at home for the median EPA-rated car, $52 a month at 1,125 miles, using the EIA residential average of 14.88 cents per kWh. The most efficient car here, the Lucid Air Pure RWD, costs $39 a month; the least efficient, the GMC Hummer EV Pickup 3X, $109.
Is it cheaper to charge an EV than to buy petrol in Mississippi?
Yes. At 14.88 cents per kWh the median car costs $52 a month against $170 of petrol for a 27 mpg car at $4.07 a gallon — $118 a month in favour of Mississippi, $1,410 a year.
How many fast chargers are there in Mississippi?
345 plugs across 99 sites (AFDC, 2026-09-16) for 7,200 registered cars, which is 21 per plug and among the easiest ratios in the country. DC fast only — Level 2 is a different question.
Can a non-Tesla use a Tesla charger in Mississippi?
Where the site is open to other brands, yes, with the right adapter. 25 of the 99 fast-charging sites in Mississippi carry the NACS plug (25%) and 87 carry CCS1 (88%), so a CCS car still has the larger of the two networks to fall back on. The plug on each car is listed on its model page.
Which electric car is cheapest to charge in Mississippi?
The Lucid Air Pure RWD, at 23.1 kWh per 100 miles: $3.44 per 100 miles and $39 a month in Mississippi. Picking it over the GMC Hummer EV Pickup 3X is worth $70 a month here, which is as much as the Mississippi rate ever makes efficiency worth; the full efficiency order is the same in every state.
