Ways to convert your VW Beetle from gasoline to electric!

Green Motor Tech to introduce you ways of how to convert VW Beetle from gasoline to electric from the aspect of drive system!



When converting a VW Beetle from a gasoline car to an electric vehicle, here are some additional steps and considerations:

Vehicle Assessment: Assess the overall condition of the Beetle, including the body structure, mechanical components, and electrical system. Ensure the vehicle is suitable for electric conversion and understand any potential limitations and challenges.


Design and Planning: Develop a detailed conversion plan, considering factors such as battery placement, motor integration, and wiring modifications. Collaborate with experts and engineers to ensure the feasibility and optimize performance of the conversion.


Fuel System Removal: Safely remove the fuel tank, fuel lines, and other components related to the fuel system. Properly dispose of any hazardous substances, ensuring compliance with environmental regulations.


Rewiring: Completely redo the vehicle’s electrical wiring to accommodate the components required for electrification. This includes installing new harnesses and connecting the battery pack, motor controller, and other necessary electrical equipment.


Battery Integration: Select and install an appropriate battery pack, considering factors such as capacity, voltage, and weight distribution. Ensure the battery pack is securely installed and correctly connected to the vehicle’s electrical system.


Motor Installation: Choose an electric motor that meets the vehicle’s performance requirements. Install the motor in the same location as the original engine, ensuring proper alignment with transmission system components.


Cooling System: Design and install a cooling system to regulate the temperature of the electric components, including the battery pack and motor. This helps improve the efficiency and lifespan of the battery and electric system.


Powertrain Integration: Connect the electric motor to transmission system components (such as a gearbox or differential) to efficiently transfer power to the wheels. Modify or adapt existing components as necessary.


Battery Management System: Install a battery management system (BMS) that monitors important parameters of the battery pack, such as state of charge and balancing. The BMS helps optimize battery efficiency and ensures safe operation.


Testing and Debugging: Conduct rigorous testing to ensure all electrical connections are secure and functioning properly. Adjust system settings, such as motor controller programming and regenerative braking, to achieve optimal performance and efficiency.


Interior and Aesthetics: Enhance the interior space of the Beetle, adding modern amenities such as upgraded infotainment systems, air conditioning, and smart connectivity features. Ensure the integration of new components aligns with the Beetle’s classic appearance.


Compliance and Certification: Ensure the converted electric vehicle complies with all relevant safety and emissions regulations. Seek appropriate certification and inspections to ensure legal compliance and peace of mind.


Please note that the conversion process may vary based on specific requirements, components, and expertise. Throughout the conversion process, it is important to consult professionals and adhere to local regulations.


Here are the actual steps involved in the installation of the drive system from a drivetrain perspective:


Assess the vehicle: Evaluate the vehicle’s existing drivetrain components, such as the engine, transmission, and differential. Determine the compatibility of the components with the chosen drive system. For Beetle, because it is very light, A 10kw rated power motor can give around max speed 80km/h,  15KW rated motor, air cooling you can get a acceptable speed such as 90km/h. To reach more than 100km/h, Then you need consider liquid cooling motor system, more than 25KW, such as 30KW, 50kw etc. Higher power motor you adopt, higher speed you can get.


Remove the existing drivetrain: Safely remove the engine, transmission, and other drivetrain components from the vehicle. Take precautionary measures to support and protect the vehicle structure during the removal process.


Modify or adapt existing components: Modify or adapt the vehicle’s transmission system, such as the gearbox or differential, to accommodate the new drive system. This may involve making adjustments to the mounting points or shaft lengths.


Mount the electric motor: Install the electric motor in the vehicle, ensuring proper alignment with the modified or adapted transmission system. Securely fasten the motor to the vehicle chassis to minimize vibrations and ensure stability.


Connect the motor to the new transmission: Establish a mechanical connection between the motor and the modified transmission system. This may involve using couplings, adapters, or custom-made components to ensure a proper fit and alignment.


Install motor controller: Mount the motor controller, which controls the motor’s speed and torque, in a suitable location within the vehicle. Ensure proper wiring and connections between the motor, controller, and vehicle’s electrical system.


Connect power source: Integrate the chosen power source, such as batteries or fuel cells, into the vehicle’s drivetrain system. Install the necessary wiring and connections to provide power to the motor and motor controller.


Test and calibrate: Conduct thorough testing to ensure the proper functioning of the drive system. This includes verifying the motor’s performance, checking for any abnormal vibrations or noises, and calibrating the motor controller for optimal efficiency and responsiveness.


Ensure safety and compliance: Ensure that the installation of the drive system meets all safety standards and regulatory requirements. This may involve inspections, certifications, and adherence to specific guidelines or codes.


Fine-tuning and optimization: Continuously monitor and fine-tune the drive system for optimum performance and efficiency. Make adjustments to parameters such as motor control settings, gear ratios, and cooling systems as necessary.


It is important to note that the installation process may vary depending on the specific drive system chosen, the vehicle’s design, and other factors. Professional expertise and adherence to manufacturer guidelines are crucial for a successful and safe installation.
