Quick answer
Budget about 35,000–65,000 THB all-in (charger, standard installation, safety gear and meter fees), with roughly 50,000 THB as a sensible starting figure. Check your car's onboard AC limit before paying for a 22 kW unit: the BYD Atto 3 (MY2026) takes 7 kW AC and the BYD Sealion 7 takes 11 kW, so a bigger wallbox adds nothing. Insist on a dedicated circuit and an RCD Type B.
1. Start with your car, not the wallbox
An AC wallbox only supplies controlled AC power. Your car's onboard charger converts it to DC and sets the real limit. The slowest of supply, wiring, wallbox, cable and car wins, so a 22 kW wallbox cannot make a 7 kW car charge faster.

| BYD Atto 3 (MY2026) | Type 2 | 7 kW | BYD MY2026 brochure |
| BYD Sealion 7 (all variants) | Type 2 | 11 kW | BYD brochure; Rêver Thai model page, 16 Oct 2026 |
| BYD M6 | Type 2 (CCS2 DC) | 7 kW | Rêver Automotive product page |
| MG4 | Type 2 (CCS DC) | Not checked | MG Thailand owner manual, May 2024 |
| Deepal New S07 | Type 2 (CCS2 DC) | About 7 kW reported (another catalogue lists 6.6 kW); not confirmed | Autolifethailand launch report, Oct 2025; EVAT Directory 2025 |
| GWM ORA Good Cat, Zeekr 009 | Type 2 (CCS2 DC) | Not checked | EVAT Directory 2025 |
Check your exact model and year in its Thai manual. Brand alone does not tell you the AC limit. We have not verified GB/T or NACS on any of these Thai-market cars; those we checked list Type 2.
What the supply can deliver (calculated, not product ratings)
- 220 V single-phase × 32 A ≈ 7.0 kW
- 380 V three-phase × 16 A ≈ 10.5 kW
- 380 V three-phase × 32 A ≈ 21 kW (only useful if your car accepts it, and your house is three-phase)
Most Thai homes have single-phase service, so 7 kW is the realistic ceiling unless you already have a three-phase connection.
2. Where the money goes
| Item | Typical cost (THB) |
|---|---|
| Wallbox, 7.4 kW single-phase | 15,000–25,000 |
| Wallbox, 11 / 22 kW three-phase | 30,000–45,000 |
| Safety gear: sub-board, breakers, RCD Type B (per set) | 4,000–7,000 |
| Electrician labour | 6,000–12,000 |
| Wiring and conduit | Depends on distance from the main board to the parking spot |
| Meter change or extra-capacity request fee (MEA/PEA) | 700–5,000, depending on meter size |
| All-in total | about 35,000–65,000 |

3. Wallbox options seen in Thailand
| Option | Power | Price seen (THB) | Source and our check |
|---|---|---|---|
| Tesla Wall Connector (Type 2) | Up to 22 kW (1- or 3-phase) | 23,000 hardware, install extra | Tesla Thailand shop, 16 Oct 2026. Listing showed out of stock. Type 2 plug, so check your car's AC limit. |
| ABB Terra AC W22 | 22 kW three-phase | 30,500 or 45,000 | One Thai retailer shows both prices on different pages; the lower excludes VAT and installation. Get a written quote. |
| BYD original wall charger | About 7 kW | 12,000–15,000 | Reported by EV Phuket, 27 May 2026. Not independently checked by us. |
| Budget Type 2 units (Thai Watsadu private label, Tuya-app units) | 7–22 kW | About 9,900–14,900 | Reported by retailers in 2026. Not checked by us. TIS certificate not verified. |
| Schneider EVlink Home | — | — | Schneider Thailand marks the range "Discontinued" (legacy). Don't plan around it. |
Installers also sell branded 7 kW packages (Delta, ABB Obsidian, Autel and others); one installer's quotes in mid-October 2026 were reported at roughly 37,000–40,000 THB installed. We have not verified that. Prices move with promotions, so treat everything here as a reference, not a quote.
4. Safety rules your installer should follow
Non-negotiables
- Dedicated circuit for the charger, not shared with other loads.
- RCD Type B (30 mA), or the documented Type A/F plus 6 mA DC-detection alternative. Standard Type AC protection may miss DC leakage from EV charging.
- Proper protective earthing. Motorist Thailand also recommends a separate EV earth rod (resistance 5 ohm or less).
- Conductor rating at least 1.25 × the charger's input current. Your electrician sizes the cable; do not copy a wire size from a website.
- An installer who gives a written warranty and an engineer's sign-off if possible.
These points follow the joint MEA/PEA/ERC installation standard MPESTD-001:2563 (2020), which covers houses and condominiums. It does not cover vehicle-to-home (reverse power).
Be careful with unbranded marketplace units. In a 2022 UK test, all three sampled marketplace EV charging cables failed (Electrical Safety First, 29 March 2023). That proves nothing about every cheap unit, but it is a reason to buy from a seller who gives paperwork and warranty.
5. The MEA / PEA process
- Choose meter size. Many homes have a 15(45)A meter. Options are upgrading the main meter to 30(100)A or higher, or asking for a second meter for the car. Confirm which your local office prefers.
- Prepare the wiring with a licensed electrician: dedicated circuit, RCD Type B, earthing, photos of the finished work.
- Apply via MEA Smart Life or PEA Smart Plus (or at the office) with your ID, house registration and EV invoice or booking document.
- Inspection, then meter change. Expect about 7–14 business days after inspection; 2–4 weeks overall.
Source: Motorist Thailand, 21 May 2026. Fees, timing and requirements vary by office, and transformer upgrades can cost extra. Condos and villages usually need written approval from the juristic person or landlord before any work, so ask first.
6. What electricity costs you
Time-of-use (TOU) pricing is the reason home charging can be very cheap. Off-peak runs 22:00–09:00 on weekdays, plus weekends and listed public holidays. It applies to the whole house, so look at your total evening and daytime use before switching.
| Utility | On-peak (THB/kWh) | Off-peak (THB/kWh) | Source |
|---|---|---|---|
| PEA (provincial areas, incl. Chiang Mai) | 5.7982 | 2.6369 | Capsolar guide, 2026 table; same figures in Motorist Thailand, Jan 2024 |
| MEA (Bangkok area) | 5.2674 | 2.1827 | Motorist Thailand, Jan 2024. Not confirmed for 2026 |
Base rates before the Ft charge, the monthly service charge and 7% VAT. One 2026 guide lists Ft at +0.1623 THB/kWh for Sep–Dec 2026. We could not confirm MEA's current residential TOU rate, so check your latest bill or the utility's tariff page.
Calculated by us from base rates. Excludes Ft, VAT, service charge and charging losses (typically around 10%).
7. Incentives
We found no national household wallbox rebate in Thailand. Government support targets vehicle production and public charging. The practical saving is a dealer bundle: some brands include a wallbox or discounted installation with a new car, so ask before buying one yourself. See also Thailand EV incentives.
8. Quick FAQ
Can I just use the cable that came with the car?
Many cars ship with a portable charger, but it charges slowly and loads the house wiring for hours. If you use it, use a properly earthed, dedicated outlet rated for continuous load and have an electrician check it. A fixed wallbox on its own circuit is the safer long-term setup.
Is a 22 kW wallbox worth it?
Only if your house is three-phase and your car accepts more than 11 kW AC. For most Thai homes and cars, 7 kW is enough: eight hours at 7 kW delivers roughly 50–56 kWh.
Do I need a separate meter?
Not always. Some owners upgrade the main meter and move the whole house to TOU; others request a second meter. Ask your local MEA or PEA office which they prefer.
