Charging cost

How much does it cost to charge a BYD Seal Dynamic 100KW in Singapore?

About $11.97 per 100 km at the median AC rate of $0.69/kWh — roughly $162 a month at 1,350 km, the distance the average Singapore car actually covers. That is about 45% less than a comparable petrol car. Charge at the island's cheapest public charger and it drops to $5.82 per 100 km.

Monthly cost by distance driven

Per month	Cheapest AC	Typical AC	Typical DC	Petrol
500 km	$29	$60	$61	$110
1,000 km	$58	$120	$123	$219

2,000 km	$116	$239	$245	$438

One charge, 20–100%

That puts 49.1 kWh into the battery. You are billed for 54.6 kWh, because 5.5 kWh is lost to conversion and thermal management on the way in. On a 7.4 kW AC charger that costs $37.93 and takes about 6 h 38 m. On a 120 kW DC charger: $38.89, roughly 45 m.

This car uses an LFP (lithium iron phosphate) pack, so charging to 100% regularly is fine — manufacturers recommend it, because a full charge is how the battery management system rebalances cells and keeps the range readout accurate.

Its onboard charger accepts up to 11 kW on AC, so the 22 kW AC bays around Singapore will not charge it any faster than an ordinary 7.4 kW one — worth knowing before you drive out of your way for a higher-rated charger.

Work it out for your own mileage

Consumption figures come from LTA's own homologation data, and the rates are the live medians across Singapore's public charging network. Charging losses are included — you pay for what crosses the charger's meter, not what reaches the battery.

$162 a month · $11.97 per 100 km · 233 kWh billed

About $134 a month less than an equivalent petrol car (6.5 L/100 km at $3.37/L).

Assumes 10% charging losses on AC and 5% on DC. Distance starts at 1,350 km a month — a 2025 Singapore car averaged 16,200 km a year, per LTA's mileage survey. Petrol price as of 2026-09-05; your actual cost varies with driving style, aircon use and battery condition.
