Electric vehicle charging

More and more drivers are adopting the EV lifestyle, as electric vehicles deliver many worthwhile benefits. From releasing zero harmful emissions to their advanced tech features, there are plenty of reasons to make an EV your own. If you are thinking about making the switch for yourself, you may be wondering, “How do electric cars work?” It’s a common question we receive here at Sam Leman Automotive Group. So, how does an electric car work? Do electric cars have engines? We dive into the answers below. 



How Does an Electric Car Work?

How do electric cars work? Battery electric vehicles are outfitted with an electric motor and a large traction battery to power the electric motor. When it comes time to charge the battery, the vehicle must be plugged into a wall outlet or charging station. This means there are zero tailpipe emissions, and there is no need for typical liquid fuel components, like a fuel pump, fuel line, or fuel tank. 

Key Components of an Electric Car

  • Battery (all-electric auxiliary): This battery powers the vehicle’s accessories. 
  • Charge port: This component is necessary for the vehicle to be able to connect to an external power supply for charging the traction battery pack.
  • DC/DC converter: This feature is designed to convert higher-voltage DC power from the traction battery pack to the lower-voltage DC power needed to power accessories and charge the auxiliary battery.
  • Electric traction motor: Its purpose is to drive the car’s wheels with power from the traction battery pack.
  • Onboard charger: The onboard charger converts AC electricity to DC power for charging the traction battery.
  • Traction battery pack: The traction battery pack stores the electricity that is used by the traction motor. 
  • Electric transmission: It sends the mechanical power from the electric traction motor to drive the wheels.

Do Electric Cars Have Engines? 

Do electric cars have engines? No, an engine is not needed in an electric vehicle. Instead, an electric motor replaces the traditional internal combustion engine.
