Cost of Converting an ICE Car to an EV

As electric vehicles (EVs) become more popular, many car enthusiasts are exploring the idea of converting their existing internal combustion engine (ICE) cars to electric. While this process can be rewarding, understanding the cost breakdown is crucial before undertaking the project. This guide provides a detailed analysis of the costs involved in an EV conversion.

Major Cost Components of an EV Conversion

1. Donor Car ($0 – $10,000+)

• If you already own a vehicle suitable for conversion, this cost is eliminated.
• Popular choices include lightweight cars with ample space for batteries and motor mounts.
• If purchasing a donor car, consider its condition and required modifications.

2. Electric Motor ($1,000 – $5,000+)

• The motor is the heart of the EV conversion.
• DC Motors: More affordable and simpler to install but generally less efficient.
• AC Motors: More expensive but offer regenerative braking and better efficiency.

3. Battery Pack ($5,000 – $20,000+)

• The most significant cost in the conversion process.
• Lithium-ion batteries are the best choice due to their high energy density and longevity.
• Salvaged Tesla or Nissan Leaf battery packs can be a cost-effective option.
• More batteries = more range, but also higher costs.

4. Motor Controller and Inverter ($1,000 – $5,000)

• Regulates the power delivery between the battery and motor.
• AC motors require an inverter, adding to the cost.
• The right controller ensures smooth acceleration and power efficiency.

5. Battery Management System (BMS) ($500 – $3,000)

• Monitors and manages battery health.
• Prevents overcharging, overheating, and balancing battery cells for optimal performance.

6. Charging System ($500 – $3,000)

• Includes an onboard charger and charging port.
• Higher-powered chargers reduce charging time but can be more expensive.
• Installation of a home Level 2 charger may cost an additional $500 – $1,500.

7. Transmission Adapter and Mounting Hardware ($500 – $3,000)

• Needed if retaining the existing transmission.
• Some conversions use a direct drive system, removing the need for a transmission.

8. Cooling System ($500 – $2,000)

• Some battery setups require cooling to maintain performance.
• Can involve air cooling or a liquid cooling system.

9. Instrumentation and Dashboard Upgrades ($500 – $2,000)

• Battery level indicators, power meters, and other essential gauges need to be installed.
• A custom EV dashboard can increase costs.

10. Auxiliary Systems ($500 – $2,500)

• Includes electric power steering, heating, and braking systems.
• Vacuum pumps or electric brakes may be needed for proper operation.

11. Wiring and Safety Components ($500 – $2,500)

• High-voltage wiring, fuses, circuit breakers, and safety disconnects are essential.
• Proper insulation and protection prevent electrical hazards.

12. Labor Costs ($2,000 – $10,000+)

• If doing the conversion yourself, labor costs are minimal.
• Professional EV conversion shops charge for expertise and installation.
• Some shops offer partial conversions where you handle some of the labor.

13. Legal and Registration Fees ($200 – $1,000)

• Some regions require inspections and re-registration as an electric vehicle.
• Insurance rates may change based on the conversion.

Total Cost of Converting An ICE Car to An EV

• DIY Conversion: $8,000 – $20,000
• Professional Conversion: $15,000 – $40,000+

Cost-Saving Tips

1. Use Salvaged Parts: Tesla and Nissan Leaf batteries can be repurposed for lower costs.
2. Buy Used Components: Motors and controllers from retired EVs can be refurbished.
3. Do It Yourself: Learning and doing the installation yourself significantly reduces labor costs.
4. Choose the Right Donor Car: A lighter vehicle requires a smaller battery pack, lowering costs.

Conclusion

Converting an ICE car to an EV is a significant investment but can be a cost-effective alternative to purchasing a new electric car. Understanding the cost breakdown helps in budgeting and making informed decisions. Whether you go DIY or hire professionals, an EV conversion can offer long-term savings and a reduced environmental footprint.
