Electric vehicles (EVs) are vehicles that are propelled by electric motors. These vehicles use electricity that is typically stored in rechargeable batteries.Types of electric vehicles include road and rail vehicles, surface and underwater vessels, electric aircraft and electric spacecraft.

Electric vehicles were popular in the 19th century and early 20th century, but their popularity reduced with the rapid development of internal combustion engines and mass production of cheaper gasoline (petrol) vehicles. However, their importance and popularity have been revived in the 21st century due to growing concern for the environment and sustainability.

EVs produce less carbon emissions compared to conventional vehicles, thereby reducing their impact on climate change. They are also more energy-efficient and cheaper to maintain than vehicles with internal combustion engines.

Examples of electric vehicles include the Nissan Leaf, the Chevrolet Bolt EV, and the Tesla Model S, Model 3, Model X, and Model Y.

The "Check Engine" light, a crucial component of a vehicle's onboard diagnostics system (OBD), acts as an early warning sign. Illuminating either as a steady light or blinking, it signals the detection of a potential issue with the vehicle’s engine or related systems. Reasons for activation range widely from minor issues like a loose gas cap to more serious problems such as a malfunctioning catalytic converter. When the light comes on, it’s advisable to promptly check the vehicle’s manual and consult with a professional mechanic to diagnose the exact problem, ensuring it doesn’t escalate into a more significant, costly repair. Ignoring this warning can lead to decreased performance, higher emissions, and even engine damage.
