Charging costs
An idle fee is what a network charges for leaving the car connected after it has finished charging. Almost every operator starts that clock when the session ends, not when your parking does — so a full battery at 7pm and a return to the car at 8pm is an hour of idle time, whatever the car park says. The exception is Tesla: at a busy Supercharger its congestion fee can start while the car is still charging, once the battery reaches 80%.
9 operators, between them 2,590 of Singapore's 2,811 charging locations, publish an idle-fee policy — though several only say a fee may apply, without a rate. A dash means the operator does not publish that detail.

These operators run public chargers but do not put an idle-fee policy anywhere you can read it before plugging in. That is the answer, not an omission on our part — check the operator's own app, and assume a fee may apply.
Keppel Volt asks drivers to move within a 20-minute grace period after charging ends, but publishes no idle fee.
