Background
As part of the trinational research project ASIMUTE , the FHNW School of Engineering and Environment has developed a free online tool that enables the planning and analysis of Vehicle-to-Home (V2H) systems in combination with photovoltaic (PV) systems and optional stationary battery storage in private households.
Unlike existing solar calculators on the market, the tool also considers the integration of electric vehicles into the energy management of PV systems. This is achieved through targeted control of the charging process or, where technically feasible, through bidirectional charging – allowing the electric vehicle not only to be charged but also to discharge electricity to meet household energy demand.
The tool was developed in response to the growing need to effectively combine the increasing adoption of electric mobility with the expansion of photovoltaic energy. Its primary objective is to maximise self-consumption of solar energy. The focus was on creating a user-friendly application that takes technical, economic and environmental aspects into account.
The tool can be accessed directly online here .

Objectives
Das Online-Tool verfolgt folgende Hauptziele:
- System sizing and analysis of systems comprising a photovoltaic (PV) installation, an electric vehicle and an optional stationary battery storage system.
- Modelling of eight different operating strategies, including options for smart charging management and bidirectional charging of electric vehicles.
- Calculation of technical, economic and environmental key performance indicators, such as self-consumption rate, energy self-sufficiency, investment costs, financial returns and CO₂ savings.
- Simulation of different scenarios based on individual input parameters, such as driving profiles, system sizes and energy prices.
- Graphical presentation of results to facilitate interpretation and comparison.
- Free and easy access via the FHNW website for interested end users.
Results
The developed tool offers:
An online application that calculates hourly household energy flows over an entire year based on user-defined system parameters.
The selection and simulation of eight different operating strategies, combining photovoltaic systems, electric vehicles and stationary battery storage with different charging and discharging strategies for the electric vehicle.
The presentation of technical key performance indicators, such as self-consumption and self-sufficiency rates, as well as energy flows.
An economic assessment based on investment costs, operating costs and cost savings over the system's lifetime.
An assessment of the environmental benefits based on CO₂ emissions savings.
An intuitive web interface with a clear structure and user-friendly navigation.
