One charge: how long, and how much?
Pick the vehicle, choose which percentages to charge between, then enter the station's power and rate. The result updates instantly, and the link can be shared with your exact figures.
Charging 60% of the battery means putting in 18 kWh, taking 23 min – 35 min, and costing Rp 46.361.
- The catalogue does not record this vehicle's maximum charging power, so the figure above assumes the full station power is accepted. If the vehicle's limit is lower, it takes longer.
- The time is a range, not a single figure: the power actually flowing depends on each vehicle's charging curve, the battery's temperature, and how many other vehicles share the same station.
- What you pay is more than what enters the battery: some energy becomes heat. This calculation uses 96% efficiency for DC charging, and that is an estimate — the catalogue has no figure for it.
Worked examples
Charging 20–80% at a 50 kW DC SPKLU at Rp2,466/kWh. The figures come from the same function as the calculator above — pick a vehicle to recalculate.
| Vehicle | Energy in | Time | Cost |
|---|---|---|---|
| BYD Atto 1 | 18 kWh | 23 min – 35 min | Rp 46.361 |
| Jaecoo J5 EV | 36,5 kWh | 46 min – 1 hr 10 min | Rp 93.862 |
| BYD M6 | 33,2 kWh | 42 min – 1 hr 4 min | Rp 85.385 |
Charging FAQs
Why does charging stop at 80%?
Above 80%, DC charging tapers sharply — the last 20% can take as long as the previous 60%. Factory claims almost always read 10–80% for this reason.
Why do I pay for more than goes in?
Some energy becomes heat in the cable and battery. This calculator assumes 96% efficiency for DC and 88% for AC — both estimates, as catalogues never state the figure.
What is the difference between AC and DC charging?
AC (up to 22 kW) goes through the car's onboard charger: slow but steady — home sockets and wallboxes are AC. DC (above 22 kW) goes straight to the battery: fast but slows near full — fast SPKLU stations are DC.
Is a 150 kW station always faster than a 50 kW one?
Not necessarily — a car only accepts up to its own limit. If your car's limit is 50 kW, plugging into a 150 kW station still charges at 50 kW. Our catalogue does not record each vehicle's limit yet, so the maths assumes the full station power is absorbed.
What's not counted here
- Charging time is always a range, and that is deliberate. Nameplate power rarely flows the whole way: every vehicle charges differently, a cold or overheated battery charges slower, and one station shared by two cars splits its power.
- The battery capacity in the catalogue is a gross figure. Part of it is never used to protect cell life, so “0%” on the car's screen is not an empty battery.
- The equivalent range is derived from factory claims (WLTP/NEDC). On real roads it is almost always shorter — shorter still on motorways, in rain, or with the air conditioning running flat out.
- Charging rates differ between operators and may include service charges or their own parking tariff, which are not counted here. The default figure is an estimate; replace it with what is actually listed.
