How do you put an electric engine in a car?

Instead of buying an expensive new electric car, I was thinking about converting one of my gas-powered cars instead. I know EVs are better for the environment, and I want to save money in the long run. Can you tell me how to put an electric engine in a car?

Now that’s a fantastic upgrade. Electric vehicles are cost-effective and are known to last a very long time. Electric conversion replaces your car’s hoses and pipes with wires. An electric motor, EV battery, and controller replace the engine, transmission, exhaust system, and gas tank.
Here’s what we know about putting an electric engine in your car:
  • We recommend** hiring a professional**, as this type of project requires extensive electrical and mechanical experience. It’s also possible to purchase a conversion kit and have a professional walk you through each step.
  • Expect to spend about $6,000 for parts, and $1,000 to $3,000 for batteries and installation fees. If you want to go all out, it can cost more than $20,000.
  • The best cars for conversion are** light cars** under 3,000 pounds with manual transmissions. Heavy cars can restrict the electrical engine range, and automatic transmission uses up too much power.
  • You also want a car body style that can accommodate the new batteries. Light and roomy models like the Honda Civic, Ford Escort, or Nissan Sentra are all great options.
  • The two types of electrical conversions are universal kits and custom kits for specific models. An electric vehicle conversion kit costs at least $8,000 and that doesn’t include the battery.
  • It will take at least three months to convert your gas-powered car to an EV, and conversion companies will often take about six months.
Now that you know your converted vehicle will be less maintenance in the long run and much more reliable, make sure your car insurance policy also has your back. Most Americans are overpaying for their car insurance every month and don’t even know it!
