Frequently Asked Questions (FAQ)

This tool was initially developed to help friends and family in France understand the real-world costs and benefits of switching to an EV based on their specific situations. Seeing its usefulness, it was made publicly available to help a wider audience make informed decisions. You can read more on our About page.

Our calculator uses average data for vehicle prices, energy costs, efficiency, and emissions for the selected country. It provides a strong estimate for comparison purposes. However, actual figures can vary based on specific vehicle models, local price fluctuations, individual driving styles, and other factors. For precise figures, always research specific models and consult local dealers or energy providers. See our Methodology page for more details.

We aim to update key data points like average fuel/electricity prices and grid carbon intensity periodically (e.g., quarterly or annually for some datasets, or as significant changes are noted). However, these figures are dynamic. The "Version and Update History" on our About page may provide insight into recent major updates.

Currently, our calculator compares generalized categories of vehicles (e.g., typical new ICE vs. typical new EV). It does not allow for selection of specific makes and models, as that would require a much larger and constantly updated database. We recommend using our tool for an initial broad comparison, then researching specific models that fit your needs.

The "carbon payback period" is an estimate of how long you need to drive an EV for its lower operational emissions (due to cleaner electricity, hopefully) to offset the higher emissions associated with its manufacturing (especially the battery) compared to an ICE car. After this period, the EV typically has a net positive impact on CO2 emissions over its lifetime compared to the ICE car.

It depends on many factors, including the purchase price of the EV vs. an equivalent ICE car, electricity vs. fuel prices in your area, how much you drive, maintenance costs, and available government incentives. Our calculator aims to help you estimate this for your situation. Generally, EVs have lower running costs (fuel and maintenance) which can offset a higher purchase price over time.

Modern EVs offer significantly improved range, often exceeding 300-400 km on a single charge, which is more than enough for typical daily driving. Range anxiety is becoming less of an issue as charging infrastructure improves and battery technology advances. For longer trips, planning your route with charging stops is key. Our tool focuses on cost and broad environmental impact, not specific range details for models.

EVs can be charged at home (most common, often overnight using a standard outlet or a dedicated Level 2 charger), at work, or at public charging stations. The availability and speed of public chargers vary by region. In France, the charging network is continually expanding.

Over their lifetime, EVs typically have a lower carbon footprint than ICE vehicles, especially in regions with a cleaner electricity grid (like France, with significant nuclear and renewable energy). While EV manufacturing (especially batteries) has a carbon cost, this is usually offset by zero tailpipe emissions during operation. Our calculator provides an estimate of this comparison based on your country's grid.
