Do Electric Cars Use Oil?

2020 GMC Hummer EV in a forest

 

If you’re considering upgrading to an electric vehicle like the exceptional GMC Hummer EV, you might be wondering about how exactly electric cars work. For example, do electric cars need oil? What kind of fluids do they use? How does the electric motor differ from an internal combustion engine?

 

 

While there are plenty of fluids that electric cars run on, they don’t use motor oil! You’ll never need to go in for an electric car oil change, so you can put that particular bit of regular maintenance in your rearview mirror. However, it’s a good idea to know what fluids electric vehicles do require, such as brake fluid and coolant, so you can keep your car running in top condition on the Milford roads. The service team at Kent County Motors has more details on the internal workings of an EV in the guide below.

What Fluids Do You Need to Change in Electric Vehicles?

You may not need to make an appointment for an electric vehicle oil change, but there are other fluids that require refilling or topping off from time to time. Here’s a quick overview:

  • Brake fluid: EVs have a braking system just like any other type of car, and one of the most essential parts of the braking system is brake fluid. Brake fluid keeps the brakes properly lubricated so they’re as responsive as possible when you press down on the pedal, so it’s important that you keep the fluid level topped off.
  • Transmission fluid: Your transmission is essentially what makes your car run, and transmission fluid ensures that the gears are moving efficiently. Your owner’s manual will give you a specific interval for when you should get your fluids replaced.
  • Coolant: While coolant in a traditional gas-powered car keeps the engine from overheating, coolant in an EV keeps the battery and vehicle systems at a safe temperature.

Electric Vehicle Parts

While there are a lot of similarities between electric cars and their gasoline-powered counterparts – such as the use of the fluids listed above – there are some important differences under the hood. So, how exactly do EVs work? In short, they’re powered by an electric motor and a battery, while torque is generated by magnets alongside the motor. The battery needs to be recharged from time to time, either at home or on the go around Smyrna, in order to keep the motor running.

Here are the most important components of an EV:

  • Charging ports: This port is where you connect the charging cord to recharge your EV’s battery.
  • Traction motors: These motors turn your vehicle’s wheels.
  • Onboard charger: Once you’ve plugged your cord into the charging port, the onboard charger converts the external charge into DC (direct current) power.
  • DC-DC converter: This converts the high-voltage direct current (DC) power from the battery into the low-voltage current that powers the electric motor.
  • Battery: The battery stores the electricity that powers the motors as you drive.
  • Thermal system: This system keeps the electric motor and its components from overheating.
