Is home EV charging cheaper than public charging in South Africa?

At home on typical 2026/27 metro rates (~R3.30–R4.70/kWh), ~16–18 kWh for 100 km usually costs roughly R53–R85. Public DC is often ~R6–R8/kWh; SAEV Richmond ~R3.49 vs GridCars ~R7.35 per DriveElectric. Solar self-use lowers the effective home rate.

How much does 100 km cost in an EV in SA?

At ~17 kWh/100 km, roughly R53–R85 at home on common 2026/27 rates, often ~R100–R125 on typical public DC, versus roughly R180–R210 for a petrol car at ~6.5 ℓ/100 km and ~R30/ℓ inland 95 — illustrative only.

EV charging

How much does it cost to charge an EV in South Africa?

At home on typical 2026/27 metro energy rates (~R3.30–R4.70/kWh on many residential steps), about 16–18 kWh for 100 km usually costs roughly R53–R85. Public DC is often ~R6–R8/kWh — with SAEV’s Richmond site a documented cheap outlier at ~R3.49/kWh vs GridCars ~R7.35 (DriveElectric). Solar self-use can cut the effective home rate further.

Updated 26 October 2026 · Illustrative ranges — not a formal quote or legal advice.

Answer first: Most of your EV kilometres should come from home AC charging at the retail tariff you already pay — typically a few rand per kWh on 2026/27 metro schedules. A useful rule of thumb is 16–18 kWh per 100 km for many compact BEVs in mixed SA driving; at ~R3.30–R4.70/kWh that is roughly R53–R85 per 100 km. Public DC is usually dearer per kWh and best reserved for road trips. Pairing a wallbox with daytime solar self-use is how the effective cost falls further — export credits alone will not beat self-use.

Home charging — the real cost stack

Your “price per km” is (kWh used × tariff) ÷ kilometres. Tariff is the moving part: prepaid vs conventional, incline-block vs time-of-use (TOU), and whether you sit on an SSEG product with fixed network charges. City Power residential exporters must migrate prepaid accounts to TOU conventional for proper bi-directional settlement — that migration can change the evening rate you pay to charge. Detail: TOU / prepaid + EV, prepaid + solar, metro tariffs.

Scenario (illustrative)	Energy rate	~Cost / 100 km (16–18 kWh)
Home, mid residential step	~R3.50/kWh	~R56–R63
Home, upper residential step / peak TOU	~R4.50–R4.70/kWh	~R72–R85
Home, daytime solar self-use (opportunity cost ≈ export credit)	~R1.08–R1.85/kWh equivalent	~R17–R33 if PV covers the session
Public DC (typical published bands)	~R6–R8/kWh	~R96–R144
SAEV Richmond public DC (DriveElectric, Oct 2026)	~R3.49/kWh (R2.49 when site BESS SoC >90%)	~R56–R63 at R3.49
GridCars DC (DriveElectric comparison)	~R7.35/kWh	~R118–R132

Illustrative only — read your own meter and the charger app before budgeting a long trip. Incline-block tariffs punish high monthly import: an EV that adds 250–400 kWh/month can shove you into a dearer step even if the headline “average” rate looked fine last year.

Why public DC costs more (and when it is still worth it)

DC fast chargers recover capital, site rental, demand charges and battery buffers that keep pins live through load shedding. Networks such as GridCars, Chargify, BMW / partner sites and newcomers price accordingly. SAEV Charge’s Richmond DC site at the Solar MD factory drew attention because DriveElectric documented ~R3.49/kWh versus GridCars ~R7.35/kWh DC (and ~R5.88/kWh AC on GridCars). Treat promotional site rates as site-specific — confirm the live app price before you plug in. Related: public networks, Richmond tariff news.

Road-trip maths: a 40 kWh top-up at R7.35 is about R294; the same energy at home mid-step is closer to R140. Use public DC for range anxiety and corridor coverage, not as your weekday default.

Solar + EV — where the savings actually live

Metro residential export credits in 2026/27 sit near 108–185 c/kWh incl. VAT (Cape Town ~152.93, City Power 143.29, Tshwane ~108.25, eThekwini ~184.60) while you often buy at several rand. Diverting midday PV into the car therefore beats exporting those same kWh. Design the wallbox schedule (or solar-aware charger) to soak surplus after the house and battery — charge EV from solar, solar + EV sizing, feed-in table.

If your hybrid already covers evening peaks, do not empty the house battery into the car during Stage 6 unless the pack was explicitly oversized for mobility. Prioritise fridge, lights, routers and medical loads first — Stage 6 battery sizing.

Battery size and “full charge” myths

A 60 kWh usable pack charged from 20% to 80% moves about 36 kWh — not the brochure total. Cold Highveld mornings, cabin preconditioning, hills and highway speeds raise kWh/100 km. PHEVs with tiny packs look cheap per “full” charge but cover fewer electric kilometres. Always compare cost per 100 km of electric driving, not cost per plug-in session. naamsa-reported BEV sales rose sharply in 2026 (3 217 BEVs Jan–Sep vs 802 a year earlier per MyBroadband / naamsa coverage) — efficiency still varies widely by model.

Workplace and destination charging

Employer AC posts can undercut home peak rates if the business is on a commercial TOU product with cheap daytime energy — or if the site has solar. Ask whether staff pay a kWh rate, a flat monthly fee, or nothing. Apartment and estate setups add body-corporate rules — workplace charging, apartments, estates / HOA.

Install cost is separate from energy cost

A dedicated ~7.4 kW Type 2 wallbox all-in often lands roughly R17 000–R35 000+ in 2026 suburban quotes (unit + labour + CoC extras). That is a capital line, amortised over years of cheap home energy versus petrol. Three-phase upgrades and long trench runs sit outside the band. Power levels: 7.4 / 11 / 22 kW, costs: home charger cost, chooser: choosing a charger.

Petrol comparison (honest framing)

A 7 L/100 km petrol car at R23/L burns about R161 per 100 km before service. Home EV charging at mid residential steps often lands well below that — but public-DC-heavy drivers can erase the gap. Model your mix: 80% home / 20% public is a common suburban pattern once a wallbox exists.

Quick FAQ

Is home charging always cheaper than petrol? At typical 2026 residential rates and ~16–18 kWh/100 km, yes for most compact BEVs — verify with your car’s trip computer.
Does load shedding change the cost? It changes when you can charge from the grid; hybrid + battery can keep a wallbox alive only if sized for it — load management.
Should I hunt the cheapest public pin every week? Fine for road trips; daily driving should still default to home or workplace AC.

How to read a quote without getting lost

Demand a single-line diagram, a clear labour vs hardware split, and the assumptions behind any “payback” number. If savings use last year’s crisis tariff increases forever, re-run the model flat. Ask what happens if export credits fall or fixed network charges rise at the next July schedule. Keep emails — verbal promises about municipal approvals evaporate when staff rotate.
