COC for electric cars: what is different for EVs
Updated 2026-08-20 · 5 min read
Electric vehicles are type-approved under the same Regulation (EC) 2018/858 as combustion cars and receive an ordinary Certificate of Conformity. What changes is the data it carries: instead of displacement and pollutant class, an EV's COC declares battery capacity, electric range and maximum net power, and those values feed directly into registration taxes and incentive schemes.
What does an EV's COC record?
The emissions sections still exist, but for a pure electric vehicle the CO₂ entry reads zero and the pollutant class fields are not applicable. The propulsion sections carry the meaningful data instead.
For plug-in hybrids both sets are populated, with a weighted CO₂ figure and an electric-only range, which is why hybrid certificates look considerably busier than either extreme.
- Maximum net power and 30-minute rated power in kilowatts
- Traction battery capacity and nominal voltage
- Electric range measured under WLTP
- Energy consumption in watt-hours per kilometre
- CO₂ recorded as zero for battery-electric vehicles
Why the COC matters more for an EV
Several member states link registration tax, company-car taxation and purchase incentives to CO₂ or to electric range. Since the COC is the document those figures are read from, it decides what you pay and what you can claim.
Dutch BPM, French malus écologique and various regional exemptions all work this way. An EV import without a COC risks being assessed on assumptions rather than on its approved values.
Newer brands and COC availability
Manufacturers that entered the European market recently, including several Chinese marques now selling in volume, hold full EU type approval and issue COCs normally. What differs is the document channel: importers and national distributors handle requests, and processing can be slower than at long-established brands.
The exception to watch is a vehicle built for a non-EU market and shipped over privately. Those were approved to another standard, hold no EU approval and therefore have no COC, regardless of how familiar the model looks.
Coceu verifies the VIN against the manufacturer's records before charging, which is the practical way to tell an EU-approved EV from a grey import.
Key takeaways
- EVs are type-approved under the same regulation as combustion cars and receive a standard COC.
- The certificate reports battery capacity, WLTP range, consumption and electric power rather than displacement.
- CO₂ reads zero for battery-electric vehicles; plug-in hybrids carry both a weighted CO₂ figure and an electric range.
- Registration taxes and incentives are calculated from these COC values, so the document has direct financial weight.
Frequently asked questions
Do electric cars need a COC to be registered?
Yes. The requirement is identical to any other vehicle: the COC proves EU type approval and avoids an individual inspection.
Does a COC show the battery's state of health?
No. It records the battery's approved nominal capacity as built, not its current condition after use.
Can I get a COC for a Chinese-brand EV sold in Europe?
Yes, if the vehicle was approved for the European market. The request goes through the manufacturer's European channel and can take longer than at established brands.
What about an EV imported from outside the EU?
A vehicle built for another market has no EU type approval and therefore no COC, so it must go through an individual approval instead.
