Home charging: how much your fleet can save
Charging a fleet vehicle at home costs around half as much as public fast charging. Shifting part of it to home charging directly cuts your TCO.

2Where do your vehicles charge?
Set the share of public charging and charging at the office, today and tomorrow. The rest happens at home (calculated automatically). No need for exact figures: a rough range is enough to see the savings.

Questions & answers
Understanding the calculation
At home, a kWh costs 27.7 ct. on average in Switzerland in 2026 (ElCom median), and less on the night-time low tariff depending on your network operator. Charging a 50 kWh battery therefore costs around CHF 14. It is by far the cheapest option, well ahead of public fast charging.
At home, expect around CHF 5 per 100 km (18 kWh at 27.7 ct.). On public fast chargers, it is around CHF 10.60 to 12.40 (Electra prices of CHF 0.59 to 0.69/kWh). The calculator above adjusts this to your actual consumption.
On average 27.7 ct./kWh in Switzerland in 2026 (ElCom median), from 21.9 ct. in the canton of Zug to 33.2 ct. in Basel-Stadt, often less on the low tariff. Compare that with CHF 0.59 to 0.69/kWh for public fast charging (Electra prices).
Yes, on energy: it is a recurring gain, separate from the hardware investment. Every kWh moved from public fast charging to home charging costs around half as much.
On energy, moving charging from public fast chargers (CHF 0.59 to 0.69/kWh) to home (around 27.7 ct./kWh) roughly halves the cost of those kilometres. For a fleet of 100 vehicles driving 30'000 km a year, that means several tens of thousands of francs a year.
Most network operators offer a low tariff, usually at night and at weekends, when a kWh costs less. A vehicle plugged in at home charges precisely at night: it benefits from the lowest tariff, without the driver having to do anything.
A public fast-charging stop ties up the driver for 20 to 30 minutes. If that time would normally be productive, it has a cost, which the calculator can value at the cost of an FTE (adjustable share lost). At home, the vehicle charges overnight without tying up the driver.
There are several solutions: a smart charging station, a smart cable or tracking software, with very different costs once management is taken into account. The next simulator compares their annual cost.
Learn more: how much does it cost to charge an electric car at home?
At home, charging an electric car costs 27.7 ct./kWh on average in Switzerland in 2026, and less on the low tariff since the vehicle charges overnight. The price depends on the municipality: from 21.9 ct. (median for the canton of Zug) to 33.2 ct. (Basel-Stadt). On public fast chargers, the price rises to CHF 0.59 to 0.69/kWh. The same vehicle can therefore cost around twice as much depending on where it is plugged in.
In terms of use, that is around CHF 5 per 100 km at home, compared with CHF 10 to 12 on public fast chargers. Home charging remains by far the cheapest option.
For a fleet, the stakes are high: most vehicles spend every night at home. Shifting more charging to home lowers the electricity bill every year. It is a direct, recurring TCO lever, with no hardware investment to pay off.

Our kWh price assumptions for 2026
The simulator uses 2026 reference prices, which you can adjust. The price per kWh varies widely depending on where you charge, which explains the difference in savings between home charging and public charging.
Charging location | kWh price 2026 | Cost per 100 km (18 kWh) |
|---|---|---|
Home, canton of Zug median | 21.9 ct. | around CHF 3.95 |
Home, Swiss median | 27.7 ct. | around CHF 5 |
Home, Basel-Stadt median | 33.2 ct. | around CHF 6 |
Electra fast charging, with subscription | CHF 0.39 | around CHF 7 |
Electra fast charging, without subscription | CHF 0.59 to 0.69 | around CHF 10.60 to 12.40 |
Sources: ElCom / Electra prices 2026. Reference consumption 18 kWh/100 km.
Savings examples for a fleet
Fleet of 50 vehicles, 25'000 km/year, 70 % home charging: shifting public fast charging to home saves around CHF 1'000 per vehicle per year. Charging at home rather than on public fast chargers roughly halves the energy cost.
Once the savings are quantified, the next step is to secure them: reimburse each driver at real cost, with documentation compliant with the salary certificate, without installing a charging station. Have my savings checked by a Voltaback expert.
