The BYD Dolphin is the cheapest electric car on Koh Samui and by some margin the most common - BYD sells more EVs in Thailand than anyone, and the Dolphin is its volume model. A 44.9 kWh lithium-iron-phosphate battery gives roughly 300 km of real island range, the cabin is far better equipped than the price suggests, and running costs are a fraction of an equivalent petrol hatchback.

Any minor damage is deducted from the deposit and the balance returned. We photograph every panel, the interior, the fuel or charge level and the odometer at handover, and you get those timestamped photos with your digital contract - so there is a record to compare against rather than an argument.
Couples and small families trying an EV for the first time, and anyone renting for a week or more where the fuel saving compounds. It is the lowest-risk way into electric on the island: cheap, common, and easy to get support for.
Three hundred kilometres against a 51 km ring road means you will charge roughly twice a week even with heavy sightseeing. A full day out - Big Buddha, Fisherman's Village, the Na Muang waterfalls and back to Lamai - is under 90 km. Where the Dolphin's smaller battery shows is hill bases: if your villa is up a steep climb above Chaweng Noi or Bophut, expect meaningfully less range and plan on charging every second or third day. If that describes your stay, take the Extended Range version instead.
Around 300 km of real island driving, less if you are based up a hill. For context the ring road is 51 km all the way round and a heavy day of sightseeing rarely passes 90 km, so a full charge covers three or four days.
Public DC chargers cluster around Chaweng, the airport and the main shopping centres, on networks including PEA VOLTA, EA Anywhere and PTT EV Station PluZ. Many hotels and villas also have a wallbox or will let you use a 3-pin outlet overnight. Confirm with your accommodation before you book - that is the single thing that determines whether EV rental here is effortless or mildly inconvenient.
The standard Dolphin is cheaper and fine for most stays on the coastal strip. The Extended Range has a 60.5 kWh battery, roughly 400 km of real range and a faster motor, and it is the better choice if you are staying up in the hills, renting for a month, or planning the mainland ferry trip.
