Selling an Electric Car in Switzerland: Battery Health, Depreciation and Timing

Electric vehicles now account for a significant share of new registrations in Switzerland, and the used EV market is growing just as fast. If you want to sell a Tesla Model 3, a Renault Zoe or a VW ID.4 today, you will quickly notice that valuation works differently than for a petrol car. Mileage and service history matter, but the condition of the traction battery matters more.

Why electric cars are valued differently

With a combustion engine, a buyer estimates residual value from age, mileage, brand and general condition. With an EV, one component accounts for roughly 30 to 40 percent of the original vehicle value: the battery. A replacement costs between CHF 8,000 and CHF 20,000 depending on the model. Buyers therefore calculate cautiously whenever battery condition is unclear.

Technical progress adds pressure. A car with a real-world range of 250 km sits in the showroom next to models offering 450 km, which pushes prices of older EVs down faster than comparable petrol cars.

State of Health: the key number when selling an EV

SoH stands for State of Health and shows how much of the original battery capacity remains. A three-year-old car with 50,000 km typically sits between 92 and 96 percent. Most manufacturers guarantee 70 percent remaining capacity for 8 years or 160,000 km.

How to document battery condition

Many garages and testing centres issue a battery certificate for CHF 100 to 200. Several models display the SoH value directly in the on-board menu or via an app. Written proof almost always pays off: it removes risk for the buyer and saves you from blanket deductions.

Depreciation and the right moment to sell

Electric cars lose value sharply in the first three years, often 45 to 55 percent. After that the curve flattens. If your vehicle dates from 2019 to 2021, the steepest part of the depreciation is usually behind you.

• Sell before the battery warranty expires: remaining coverage noticeably increases the price.
• Sell before the next MFK: the first inspection is due after four years, then after three, then every two years.
• Spring rather than winter: EVs show less range in cold weather, and demand is clearly stronger from March to June.
• Do not wait for the next update: new model generations cut prices faster than owners expect.

What Swiss buyers actually want to see

Prepare the sale with a short checklist. Complete accessories are often worth several hundred francs:

1. Both charging cables: the Type 2 cable for the wallbox and the emergency cable for household sockets
2. Charging cards and network access, where transferable
3. Service booklet or digital service records, including software updates
4. Vehicle registration document, latest MFK report and any warranty papers
5. A second set of wheels, particularly sought after because of EV weight
6. SoH proof or a screenshot from the manufacturer app

One note on costs: since 1 January 2024, imported electric vehicles in Switzerland are again subject to the 4 percent automobile tax. Cantonal discounts on road tax remain in place, however, and in several cantons EVs are heavily reduced or exempt for the first years. This supports demand on the used market.

Leasing and outstanding balances on electric cars

Many EVs run on leasing contracts. Check the settlement amount with your leasing company before selling. If the market value is higher, the difference is paid out to you. If it is lower, the remaining balance must be covered, and a buyer who settles directly with the leasing company saves you a lot of paperwork.
