Here’s the translation:
I want to create a basic roadmap for those planning to buy an electric vehicle. How should range be calculated based on battery life, charging infrastructure, and usage needs? How much do vehicle type (SUV, sedan, hatchback) and energy consumption values affect the choice? Also, what do you recommend regarding battery warranties, maintenance costs, and recycling processes? Based on your personal experiences and research, which criteria should we prioritize to find the most efficient and long-term solution? In your opinion, what are the most critical factors?
What should you consider when choosing an electric vehicle? General approaches

Yep, I had the same questions when switching to an electric car. First, you should calculate the range by multiplying the car's kWh/100 km consumption by your average daily km and adding a 20-30% safety margin. For example, if you plan to drive 50 km daily in a sedan that consumes 15 kWh/100 km, you’ll need around 7.5 kWh, so adding an 8-9 kWh battery with a target range of around 400 km makes sense. Charging infrastructure is also critical; since I have a 22 kW AC charger at home, I chose a model with 11 kW fast-charging points at my workplace, allowing us to reach 80% charge in just 30-40 minutes even on long trips.
The vehicle type makes a big difference in energy consumption; SUVs have higher kWh/100 km values, so the same battery capacity results in a shorter range. If you mostly drive short distances in the city, hatchbacks or sedans are more energy-efficient. As for battery warranties, opting for models with at least 8 years or 150,000 km (whichever comes first) coverage reduces long-term costs. In terms of maintenance, regenerative braking extends the life of brake pads, which is a financial plus. For recycling, check manufacturers' battery take-back programs—some offer discounts on servicing for used battery purchases.
I think the most critical factor is balancing range, battery capacity, and charging infrastructure while choosing a model with a solid battery warranty; once you get that right, the rest becomes much more manageable.
