The Components of an Electric Car

Electric cars are becoming increasingly common, with the goal to produce only electric cars by 2030. Despite this, many individuals find themselves feeling skeptical about electric cars. They’re still a relatively new phenomenon, and making the shift from gas to electricity will be significant. Soon enough, though, motorists won’t have any choice but to switch from gas to electric cars. 

Electric cars are otherwise known as battery electric vehicles (or BEVs). What this means is that these vehicles have an electric motor rather than an internal combustion engine. In the powering of these vehicles, a large traction battery pack is used. This must be plugged into charging equipment to receive the power it needs. Electric vehicle charging equipment is otherwise known as electric vehicle supply equipment (EVSE). 

Since these vehicles run solely on electricity, no emissions are released from the tailpipe, and the usual fuel components aren’t featured. These components include gas tanks, fuel lines, and fuel pumps.

So, it’s clear what an electric car doesn’t contain, but what is it that they do contain? Detailed below are the components of an electric car. 

Traction Battery Pack

Firstly, electric cars contain custom battery packs. These are responsible for storing electricity to be used by the electric traction motor.


An electric car’s transmission transmits the electric traction motor’s mechanical power to power the wheels. 

Thermal System

It’s essential that any type of vehicle maintains a suitable operating temperature, which is where the thermal system comes in. Power electronics, the electric motor, and the range of the engine are all affected by this. 

Power Electronics Controller

The power electronics controller runs the electrical energy stream via the traction battery. This manages the electric traction motor’s speed, as well as the torque that’s produced. 

Onboard Charger

Electric cars come with an onboard charger, which converts the AC electricity that’s provided by the charge port into DC power. This is done to charge the traction battery. Similarly, the onboard charger monitors battery features, including the pack’s charging state, temperature, current, and voltage. This is achieved via communication with the charging equipment ionity ladestationen map

Electric Traction Motor

The role of this motor is to power the wheels of the car, which is achieved via traction from the battery pack. Motor generators are used by some cars, resulting in the performance of regeneration and drive functions. 

DC/DC Converter

A DC/DC converter is responsible for converting higher-voltage DC power from the battery pack into lower-voltage DC power. This is required for the recharging of the auxiliary battery and the running of vehicle accessories. 

Charge Port

Quite simply, the charge port enables the connection of the vehicle to an external power supply. The purpose of this is to charge the traction battery pack. 


Last but certainly not least is the battery, which ultimately works to power every element of the electric vehicle.


All in all, there’s no denying that increasing the number of electric vehicles on the market is a positive step in the right direction. While it’s a big change, the reduced carbon emissions will result in an improved environmental impact. What’s more, fossil fuels won’t last forever, which is why it’s important to phase these out as soon as possible. This provides us with plenty of time to perfect the electric vehicle market before EVs become the mainstream option. 

With more understanding will come more acceptance of electric vehicles, which is what’s needed to progress forward. All-electric vehicles are the future, and they need to be embraced. They’re becoming more accessible in terms of affordability and their quality is increasing, making them a win-win.
