Do Electric Cars Have Catalytic Converters?


Since electric cars don’t use gas, they don’t require the exact same parts that gas-fueled vehicles do, like a catalytic converter.  Electric vehicles run on entirely different systems but don’t they still need some of the components of a regular car?

A fully electric car does not have a catalytic converter. Catalytic converters reduce the amount of toxic emissions that an electric car produces. Since electric cars don’t use gas or produce emissions, they don’t use catalytic converters.

So if you own or plan on owning a fully electric vehicle, you will not need to worry about or even plan on having any issues with a catalytic converter. On the other hand, if you have a hybrid vehicle, your catalytic converter could be something you may need to worry about. Keep reading to learn more about catalytic converters and why your EV(Electric Vehicle) does not need a catalytic converter.

Do Electric Vehicles have a Catalytic Converter?

All-electric vehicles do not need a catalytic converter. Electric vehicles don’t operate on any fuels, and because of this, they don’t emit any harmful emissions that require a catalytic convertor. The only vehicles that need a catalytic convertor would be vehicles that use fuels and produce emissions that need to be reduced.

Why Does My Electric Vehicle Not Need a Catalytic Converter?

Catalytic converters are only needed for vehicles that use gas and need to reduce emissions from burning fuels. So because fully electric vehicles don’t use any gas products or produce any direct emissions, they don’t need to reduce any emissions.

Hybrid-electric model vehicles will need them for exactly that reason though, they still burn up fuel and produce emissions that require a catalytic converter.

There are three main emissions gasoline vehicles produce that electric vehicles don’t produce. These emissions are why catalytic converters are normally required in gasoline vehicles but not required in fully electric vehicles. These emissions include:

  • Hydrocarbons
  • Carbon dioxide emissions
  • Nitrogen oxide emissions

Since all-electric vehicles do not produce any of these harmful direct emissions gasoline vehicles produce, this removes the need for a catalytic converter to be installed on an all-electric vehicle.

Does an Electric Vehicle Produce any Emissions?

We like to think of our electric vehicles as totally emission-free, green machines. This is somewhat true, but electric cars aren’t 100% emission-free. Electric vehicles do not produce any direct emissions, unlike their gasoline or hybrid counterparts.

The emissions that electric vehicles produce are life cycle emissions. Although no direct emissions are produced by you, the driver, when you’re actually using the car, there are life cycle emissions that are made from the production of the vehicles.

There are two different types of emissions that come from electric vehicles, although somewhat indirectly. But if your overall goal is to go green and be more earth-friendly, these emissions are worth noting. The two emissions that are produced by electric vehicles are:

  • Direct emissions
  • Life cycle emissions

If you are still using a gasoline-fueled vehicle, then you will still be a producer of direct emissions. Going electric will give you the comfort of no longer producing those harmful emissions directly, but there are still life cycle emissions that are produced by electric vehicles.

Direct Emissions

Direct emissions are emissions that are released because of the direct action of a user. In this case, we cause direct emissions by the use of driving gasoline-fueled vehicles. Other causes of direct emissions could be:

Emissions Caused by BusinessCarbon dioxideNitrogen oxideMethaneWater vapors
Emissions Caused by FuelsHydrocarbons Carbon monoxides Nitrogen oxides

The bottom line is that everyone is still causing direct emissions at some point. At the moment, it’s hard to avoid causing any direct emissions because we still haven’t made all of the tech needed to get to a zero-emission world.

Life Cycle Emissions

Life cycle emissions are emissions that are made over the manufacturing process. These are the emissions that are produced by electric vehicles. Some examples of life cycle emissions would be:

Fuel ProductionEmissions caused by fuel production would be the emissions produced by the equipment needed to produce fuel.
Vehicle ProductionThese emissions would be emissions caused by the processes it takes to get the materials to build a vehicle.
Processing and DistributionThese emissions would be the emissions it takes to be able to process the material that is going to be used and what is caused by the process of distribution.
Recycling and DisposalRecycling and disposal emissions are caused by all the equipment it takes to go through the process to recycle and dispose of materials.

Even though your all-electric vehicle may not produce any direct emissions, some emissions are made by things like the production of electricity for the vehicles, production of all the materials needed to make the vehicles, the actual process of making the vehicle.

These aren’t things that can be made more efficient or cleaner by having a catalytic converter on your vehicle, though.

Does an Electric Vehicle Have an Exhaust System?

An all-electric vehicle will not have an exhaust system because it does not need one since it produces no emissions or gases that need to be expelled from the exhaust system. A hybrid electric vehicle will have an exhaust system, though, because hybrid electric vehicles use both gas and electricity together.

Even though they are much more efficient on gas than a regular gasoline-powered vehicle, they still produce emissions, and those emissions need somewhere to go.

Can You Install a Catalytic Converter on an Electric Vehicle?

You won’t be able to put a catalytic converter on an all-electric vehicle because an electric vehicle will have nowhere for you to put a catalytic converter. Since all-electric vehicles produce no emissions, a catalytic converter is not at all needed.

If you have a hybrid vehicle, you can put one on, but, likely, the vehicle will already come with one on it. So you should not need to install one yourself. There are only two times you’d need to install a catalytic converter on your vehicle is when your vehicle doesn’t have a catalytic converter or when your catalytic converter breaks and needs to be replaced.

Do Hybrid Electric Vehicles Have Catalytic Converters?

Hybrid vehicles will have a catalytic converter. Since hybrid vehicles still use fuel and only use electricity as more of an assistant, they still directly produce those emissions we’re all working on getting rid of. Since they still produce those emissions, we still need a catalytic converter to dampen down those emissions.

Do Hybrid Electric Vehicles Have an Exhaust System?

Hybrid electric vehicles will have an exhaust system on them. Hybrid vehicles still use gasoline, so when hybrid electric vehicles are using gasoline, they still need to do something with that fuel that gets used during those times. Hybrid vehicles are much more efficient than regular gasoline vehicles, though but not as clean as a fully electric vehicle.

Final Thoughts

A fully electric vehicle will not have one, but hybrid electric vehicles will have them. Since fully electric vehicles don’t use any fuel products or produce any emissions from burning fuels, there is no need for them to have a catalytic converter.

If a vehicle is only partially electric, though, such as a conventional hybrid or a plug-in hybrid, then unless your catalytic converter is removed, it will have a catalytic converter on it.
