Home vs. Public EV Charging in Germany: Which is More Cost-Effective?

1. Overview of EV Charging Options

With the increasing number of electric vehicles in Germany, many owners and businesses face the question: Is it more cost-effective to charge vehicles at home or at a public charging station? Both options have advantages and disadvantages that impact costs and convenience.

‍

Home EV Charging Station

Charging at home or in business facilities is the most convenient and often the most cost-effective solution. There are two common methods:

‍

Standard Household Socket (Schuko)

• Description: A 230V household socket used with a charging adapter.
  ‍
• Charging Speed: Very slow, delivering about 2.3 kW of power. A full charge can take up to 24 hours.
  ‍
• Efficiency: High energy losses due to long charging times.
  ‍

Wallbox

• Description: A fixed charging station connected to the home or business power grid.
  ‍
• Charging Speed: Significantly faster than a Schuko socket, offering 11 kW to 22 kW charging power.
  ‍
• Efficiency: High efficiency of up to 95%, minimizing energy losses.

‍

Public Charging

Public charging stations are widespread in Germany and offer a flexible alternative, especially for businesses with vehicle fleets or drivers without private charging options.

‍

Types of Public Charging Stations

• Standard Charging Stations: Provide AC charging with up to 22 kW of power.
  ‍
• Fast Charging Stations: Use DC charging and enable power levels between 50 kW and 350 kW.
  ‍
• Ultra-Fast Charging Stations: Offer extremely fast charging with even higher power levels.

‍

Availability and Convenience

• Locations: Public charging stations are often found in shopping centers, parking lots, and highways.
  ‍
• Access: Waiting times can occur, especially during peak hours or in highly frequented locations.

2. Cost Comparison: Home vs. Public

‍

Electricity Prices 2025

Home Charging

• Household Electricity Price 2025: Current rates for new customers are approximately €0.29 per kWh.
  ‍
• With Solar Power: Those with their own solar system can reduce costs to as low as €0.07 per kWh.

Public Charging

• Standard Charging Stations: €0.35 to €0.50 per kWh.
  ‍
• Fast Charging Stations: €0.50 to €0.80 per kWh.
  ‍
• 2025 Trend: Due to increasing competition, public charging prices may decrease throughout the year.

Charging Efficiency

• Home with Wallbox: High efficiency of up to 95%.
  ‍
• Schuko Socket: Lower efficiency due to longer charging times.
  ‍
• Public Charging Stations: Efficiency between 85% and 90%, depending on the provider.

‍

Conclusion

Charging at home or at a business site is generally the most cost-effective option, especially with a Wallbox or a private solar system. However, initial installation costs must be considered. Public charging stations, on the other hand, offer more flexibility and allow fast charging but are typically more expensive per kWh. Businesses with larger vehicle fleets must carefully calculate whether an in-house charging infrastructure or public charging options are more economical. Ultimately, the choice depends on individual driving behavior and charging availability.

FAQs

‍

What are the main differences between home and public charging?

Home or business charging offers lower electricity costs and high efficiency but requires a dedicated charging station. Public charging is more flexible but more expensive and may involve waiting times.

‍

How much does Wallbox installation cost in Germany?

Wallbox costs range between €500 and €2,000, plus installation costs of approximately €500 to €1,500, depending on complexity.

‍

Are there subsidies for installing a Wallbox?

Currently, there are no nationwide subsidy programs, but some cities and energy providers still offer grants.

‍

Is it safe to charge an electric car using a household socket?

Charging with a Schuko socket is possible but not ideal due to long charging times and potential safety risks. A Wallbox is recommended.

‍

How do electricity costs for home charging compare to public charging in Germany in 2025?

Home charging costs around €0.29 per kWh, with solar energy potentially reducing costs further. Public charging stations charge between €0.35 and €0.80 per kWh, with possible price reductions throughout the year.
