Guide to Buying an Electric Car

Quick answer: an electric car makes sense if you have convenient and affordable charging available (ideally at home or work) and your typical routes fit within the real-world range even in winter. Then you'll save significantly on operation. The key is not to focus only on price and catalog range, but on real consumption, charging options, and in used vehicles, on battery condition.

Real-world range and consumption: what actually matters

The number in the brochure (WLTP) is a laboratory ceiling, not what you'll see on the display. In reality, range is affected by several things:

• Winter. In frost, battery capacity drops and heating consumes energy. Expect noticeably lower range than in summer.
• Highways. At high speeds, consumption rises quickly — an electric car is actually most efficient in the city and on regional roads.
• Driving style and elevation. Sharp acceleration and hilly terrain will reduce range.

How to calculate whether range is enough for you

1. Add up your longest typical route (e.g., commute to work and back) and add a buffer.
2. From the model's real-world range (look for tests by owners, not just brochures), subtract 20–30% as a safety margin — you won't charge to 100% every time or drain to zero.
3. Separately consider a few long trips per year (vacation). Fast charging on the road will handle that — but you want to know in advance how often you'll need to stop.

Track consumption in kWh per 100 km, the equivalent of liters for a gas car. Smaller and more aerodynamic vehicles use less energy and travel farther on the same battery.

Charging options: home vs. public

This is the most important question in the entire decision. An electric car is convenient and cheap mainly when you have somewhere to charge overnight.

Charging at home (AC, slow)

• The cheapest and most convenient option — the car charges overnight, and you wake up with a "full tank."
• A wallbox in your own garage or reserved parking space is ideal; a regular household outlet works only in emergencies and is slow.
• In apartment buildings, installation is more complicated (homeowners' association approval, connection capacity) — verify your options before buying the car.

Public charging

• AC stations (slower) in parking lots and near shops — useful when you're parked there for a while anyway.
• DC fast chargers replenish much of the battery in tens of minutes, perfect for long trips. But they're usually more expensive per kWh than home charging.
• Rates and prices vary between networks. If you mostly use paid fast chargers, operating savings compared to a gas car drop significantly.

Rule of thumb: whoever has their own charging at home or work gets the maximum from an electric car. Anyone who would rely mainly on paid fast chargers should carefully calculate the costs.

Battery capacity and lifespan

The battery is the most expensive component in the vehicle, so it makes sense to pay attention to it.

• Capacity (kWh) determines range. Bigger battery = greater range, but also higher price and weight.
• Lifespan. Modern traction batteries are built for many years and high mileage. Degradation (capacity loss) is fastest at first and then slows down.
• Battery warranty is usually separate and longer than for the rest of the vehicle, typically tied to both years and mileage and to minimum remaining capacity. Verify exact terms with the specific manufacturer.

How to extend battery lifespan

• For daily driving, don't unnecessarily charge to 100%; many manufacturers recommend regularly charging to about 80%.
• Avoid leaving a fully charged battery sitting in heat for long periods.
• Use fast charging when you need it, but not as your only daily charging method.

Operating savings and total cost of ownership

An electric car is usually more expensive to buy, but look for savings in total cost of ownership, not just the purchase price.

• "Fuel": charging at home with a low rate is significantly cheaper than petrol or diesel. Expensive fast charging eliminates this advantage.
• Maintenance: no oil changes, fewer moving parts, brakes wear slower thanks to regenerative braking.
• Taxes and fees: electric cars often get discounts, especially for businesses and sole proprietors. Specific rules change — verify current conditions.
• Residual value: for EVs, it's mainly affected by battery condition and the pace of new model development. It's still harder to predict than for established gas cars.

Create a simple table: purchase price, expected annual mileage, estimated charging costs based on where you'll charge, and maintenance savings. Only then will it show whether an EV makes sense for you.

Subsidies: count carefully

Electric vehicle support in the Czech Republic changes over time and differs depending on whether you're buying as a citizen, sole proprietor, or company. Some get direct grants, others mainly tax benefits or support for charging stations.

• Never rely on a specific amount from an article or dealer advertisement.
• Before signing, verify current conditions with official sources (ministries, grant agencies) and ask the dealer exactly what's available now.
• Watch deadlines and budget exhaustion — programs are usually limited by time and volume.

Who EVs make sense for — and who they don't (yet)

You'll probably appreciate an electric car if:

• you have your own charging at home or work,
• most of your driving is short, regular routes (city, commuting),
• you want a quiet, smooth car with low operating costs.

A gas or hybrid car might be more practical if:

• you park on the street and have nowhere convenient to charge,
• you often drive long distances with minimal time for stops,
• you need one car for everything and don't want to worry about planning charging.

As a middle ground, consider a plug-in hybrid — drive short distances electrically, rely on the gas engine on the highway. Just note that savings only come if you actually charge it regularly.

How AI can help you choose

When comparing dozens of models and ads, it pays to bring in an AI assistant. ChatGPT, Claude, Perplexity, or Gemini can compare range, price, and features in plain language and explain differences between specific vehicles.

If ads are on an AI-readable platform like AssetLog, AI can find specific offers matching your criteria directly — for example, "electric car within budget with real range over X km." AssetLog is a free platform where ad data is structured and the site allows AI crawlers, so when you ask an assistant about a vehicle, it can find and recommend the ad. In ChatGPT or Claude, you can add it as a Custom Connector via https://api.assetlog.ai/mcp.

And if you're selling an electric car: post your ad with structured data (model, year, mileage, battery capacity, real-world range, battery condition) where AI is allowed to read — then buyers will find you through AI search. Either way, always verify AI results in the actual ad — prices and availability change quickly.

Is an electric car worth it if I don't have my own outlet or garage?

It depends on your options. Without charging at home or work, you'll rely only on public stations, which tends to be more expensive and less convenient. But if you have affordable AC charging nearby (like in your employer's parking lot) and don't drive long distances daily, an EV might still make sense. For someone who parks on the street and drives a lot, a gas or hybrid car is still more practical.

How do I know the real range of an electric car, not the one in the brochure?

Take the WLTP figure as a laboratory ceiling, not everyday reality. Expect noticeably lower range in winter and on highways. The best approach is to find real tests of the specific model from owners and reviewers, then add a buffer — you won't charge to 100% every time or drain to zero.

How long does the battery last and what happens when it degrades?

Modern traction batteries are built for many years of use, and manufacturers offer a separate warranty, usually tied to both years and mileage and to minimum remaining capacity. Degradation is fastest at the start and then slows down. For used vehicles, always get the battery health (SOH) measured.

Can I count on a subsidy for an electric car?

Subsidy programs in the Czech Republic change over time and differ depending on whether you're buying as a citizen, sole proprietor, or company. Don't rely on a specific amount from an article — always verify current conditions with official sources and the dealer before signing. Businesses often have interesting tax benefits in addition to direct grants.

How much will I save on operation compared to petrol or diesel?

The main savings are in "fuel" cost if you charge mostly at home at a low rate, and in simpler maintenance (no oil, slower brake wear thanks to regenerative braking). But if you mainly use expensive fast charging, savings shrink significantly. Calculate your real costs based on where you'll charge most often.

How do I buy a used electric car — what should I watch out for?

Battery condition (SOH) and charging history are key — a car that lived on fast chargers and sat fully charged in heat ages faster. Verify remaining battery warranty, number of owners, service history, and whether software updates are current. Have the car inspected by an electric vehicle specialist.

How will AI help me find and compare specific electric cars?

Assistants like ChatGPT, Claude, Perplexity, or Gemini can compare models by range, price, and features in plain language and explain differences between vehicles. If ads are on an AI-readable platform like AssetLog, AI can find specific offers matching your criteria directly. Always verify results in the actual ad though — prices and availability change quickly.

As a seller — how do I ensure my EV ad is found by AI?

Post your ad where AI assistants are allowed to read, with structured data: model, year, mileage, battery capacity, real-world range, battery condition (SOH). On the free AssetLog platform, data is readable to AI crawlers, so when a buyer asks ChatGPT or Perplexity about a specific car, your ad can appear as a source.
