How Long to Charge an Electric Car in Indonesia? Home AC, Public AC, DC Fast

How long does it take to charge an electric car in Indonesia? The answer depends on the type of charger. With a home AC charger of around 7 kW, charging from 20% to 80% on a car with a roughly 60 kWh battery usually takes around 5 hours, so the most practical pattern is to plug in overnight. With public AC at around 22 kW, the same charge is much faster, around 1.5 to 2 hours. With DC fast charging at a public station, a 10% to 80% charge is usually around 30 to 50 minutes, which suits trips. This guide explains the charge-time formula, gives an example per charger type using car specs that exist on this site, and explains why even the fastest DC charger does not always charge as fast as its peak figure. The figures here are illustrative and stated with the word around, not a fixed promise.

Charge time = energy added divided by charger power

Charge time for an electric car follows a simple sum: the energy you need to add (in kWh) divided by the charger power (in kW) gives an estimate of the charging hours. The energy added is the battery capacity times the percentage gap, so charging from 20% to 80% on a 60 kWh battery adds around 36 kWh. Dividing 36 kWh by the charger power gives the estimated time. That is why a more powerful charger charges faster.

But there is one important limit: a car cannot accept more power than its own DC peak. A public station might be rated for hundreds of kW, but if the car only accepts a peak of 88 kW, that is the ceiling. On top of that, the DC charging curve tapers after about 80%, so the last part is slower. That is why for DC fast charging we use the sourced 10% to 80% figure, not a simple battery-divided-by-kW sum. The next three sections detail the time per charger type: home AC, public AC, and DC fast.

Home charging (AC around 7 kW): overnight

The most common everyday charging is AC at home with a wallbox of around 7 kW, which is the default home power in this site's configuration. Charging from 20% to 80% on a car with a roughly 60 kWh battery adds around 36 kWh, and 36 kWh divided by 7 kW is roughly 5 hours. That is slow, but convenient: plug in when you arrive home, full when you wake up. For a smaller-battery car such as the BYD Atto 1 Dynamic (around 30 kWh), a full home charge is clearly shorter because there is less energy to add.

Be careful with a regular home socket without a wallbox. A regular socket is only around 2.2 kW, so charging is far slower, possibly around 12 hours or more for a large charge. For an electric car, installing a dedicated wallbox is far more ideal than relying on a regular socket, and it usually needs an adequate home electrical supply. As long as the home supply is sufficient, overnight charging with a wallbox is the most practical and cheapest pattern.

Public AC (around 22 kW): a few hours

Public AC chargers, often found at shopping malls, office buildings, and car parks, are usually rated at around 22 kW, more than a home wallbox. Charging from 20% to 80% on a car of around 60 kWh, which adds around 36 kWh, takes around 1.5 to 2 hours. This suits charging while you work or shop: not as fast as DC, but fast enough to add meaningful range while the car is parked anyway.

Note that a car is also limited by its own onboard AC charger. Many electric cars accept around 7 to 11 kW of AC, so on a 22 kW public AC charger, a car with a 7 kW onboard charger still charges at 7 kW, not 22 kW. So the 1.5 to 2 hour figure above assumes a car that can use that public AC power; check your car's AC specification.

DC fast / public station: around 30 to 50 minutes

For trips, DC fast charging at a public station is the option. Charging from 10% to 80% is usually around 30 to 50 minutes, depending on the car. As a sourced example, the BYD Atto 3 Superior with a roughly 60 kWh battery and a DC peak of around 88 to 110 kW charges from 10% to 80% in around 36 minutes (source: the EV Database charging-facts data in this site's configuration, as of 2026-05-26). This figure comes from the real charging curve, not a simple division, because the power drops as the battery fills.

Remember two things. First, even the fastest DC charger cannot exceed a car's DC peak: a car with a 30 kW peak such as the BYD Atto 1 Dynamic will be far slower on DC than a car with a peak above 100 kW, even at the same station. Second, the charging curve tapers, so 80% to 100% feels slow and many drivers stop around 80% on a trip. That is why DC fast charging is ideal for topping up on a journey, while home charging is cheaper for everyday needs.

What affects charge time

Several things affect charge time besides the charger type. The starting and target percentage determine how much energy is added: a small top-up is clearly faster. Charger power can be shared when several cars charge at the same site, so the power per car drops. The car's own DC and AC limits cap how fast the car can accept, regardless of what the station can deliver. And the tapering charging curve makes the last part slower.

This site's calculator

For your own car's figures, use the calculator on this site: pick your model, enter your starting and target battery percentage, then choose a tariff. The calculator shows the charging time and the cost from the same inputs, so you do not have to work it out by hand. This calculator is for electric cars, so its preset list contains cars.

Frequently asked questions

How long does it take to charge an electric car to full?

It depends on the type of charger. In Indonesia, charging from 20% to 80% on a car of around 60 kWh is roughly 5 hours with home AC at around 7 kW, around 1.5 to 2 hours with public AC at around 22 kW, and for DC fast charging a 10% to 80% charge is usually around 30 to 50 minutes. Charging all the way to 100% on DC is slower because the charging curve tapers, so many drivers stop around 80% on a trip.

How long does it take to charge an electric car at a public DC station?

DC fast charging from 10% to 80% is usually around 30 to 50 minutes, depending on the car. As a sourced example, the BYD Atto 3 Superior charges from 10% to 80% in around 36 minutes (source: the EV Database charging-facts data in this site's configuration, as of 2026-05-26). This figure comes from the real charging curve, not a simple battery-divided-by-kW sum, because the power drops as the battery fills.

Why does home charging take longer?

Because a home AC charger has far less power than DC fast charging. A home wallbox is usually around 7 kW, while DC fast charging is tens to hundreds of kW. Dividing the same energy by much smaller power gives several hours, not minutes. The upside is that home charging is far cheaper and convenient for everyday overnight charging, so the slowness is rarely a problem.

Does the fastest DC charger always charge that fast?

No. A car cannot accept more power than its own DC peak, so a car with a 30 kW peak will be far slower at the same station than a car with a peak above 100 kW. On top of that, the charging curve tapers after about 80%, so the last part is slower. That is why we use the sourced 10% to 80% figure for DC, not a simple battery-divided-by-kW sum.
