Diy Electric Car Conversion: A Step-By-Step Guide


With the increasing awareness about climate change and the need for more environmentally friendly solutions, electric vehicles (EVs) have become a popular choice for many people. However, buying a new electric vehicle can be expensive, and not everyone can afford it. Fortunately, there is an alternative option: converting an existing gas-powered vehicle into an electric one. In this blog post, we will discuss the process of DIY electric car conversion and provide you with a step-by-step guide to help you with your project.

Benefits of Electric Car Conversion

Converting a gas-powered vehicle to electric has several benefits, including:

  • Reduced greenhouse gas emissions: Electric vehicles produce zero tailpipe emissions, which can help reduce your environmental impact.
  • Lower operating costs: Electricity is cheaper than gasoline, and electric vehicles have less maintenance needs.
  • Improved performance: Electric motors provide instant torque, which can improve acceleration and overall drivability.
  • Quiet operation: Electric vehicles are much quieter than their gas-powered counterparts.

Steps to Convert a Gas-Powered Vehicle to Electric

Converting a gas-powered vehicle to electric is a complex process, but it can be broken down into several steps. Here is a step-by-step guide to help you with your DIY electric car conversion project:

  1. Select a suitable vehicle: The first step is to choose a car that is suitable for conversion. Lightweight, aerodynamic cars with manual transmissions are generally the best choices. Older cars with fewer electronics can also be easier to work with.
  2. Remove the internal combustion engine and other components: Remove the gas engine, exhaust system, fuel tank, and other components related to the internal combustion system. This will make room for the electric motor and other necessary components.
  3. Choose an electric motor: Select an electric motor that is suitable for your vehicle and your desired performance. There are various types of electric motors available, including DC series, DC shunt, and AC induction motors. Consider factors such as torque, power, and voltage when choosing the right motor.
  4. Install the electric motor: Mount the electric motor to the transmission or use an adapter plate to connect it to the existing transmission. This will allow the motor to drive the wheels of the vehicle.
  5. Install a motor controller: A motor controller is necessary to manage the flow of electricity from the batteries to the electric motor. It also helps regulate the motor’s speed and torque, ensuring smooth and efficient operation.
  6. Add a battery pack: Choose a high-quality battery pack that can provide sufficient power and range for your electric car. Common options include lead-acid, lithium-ion, and lithium iron phosphate batteries. The battery pack should be securely mounted in the vehicle, with proper ventilation and protection from the elements.
  7. Install a charging system: Add an onboard charger to charge the batteries when the vehicle is plugged into an electrical outlet. You can also consider adding a DC fast charging system for quicker charging times.
  8. Upgrade the braking system: Electric vehicles are generally heavier than their gas-powered counterparts due to the additional weight of the batteries. As a result, it may be necessary to upgrade your vehicle’s braking system to handle the increased weight.
  9. Complete the wiring and electrical system: Connect all the components of the electric drivetrain, including the motor, controller, batteries, and charging system. Ensure that all wiring is secure and properly insulated to prevent electrical shorts and other potential hazards.
  10. Test and fine-tune: Once everything is installed and connected, test your electric car to ensure everything is working properly. Fine-tune the motor controller settings for optimal performance and efficiency.


Converting a gas-powered vehicle to electric can be a rewarding project that not only helps the environment but also provides you with a unique and efficient mode of transportation. With the right tools, knowledge, and dedication, you can successfully complete a DIY electric car conversion and enjoy the benefits of driving an electric vehicle.
