- Entry-Level and Professional Kits: Range from basic driving kits to high-performance kits with full intelligent control, depending on budget and final performance goals.
How to Choose the Most Suitable Conversion Kit?
1. Evaluate Vehicle Compatibility
Not all vehicles are easy to convert. Lightweight, structurally simple models (such as old compact cars, pickup trucks) are ideal choices. First, measure your engine compartment, chassis, and trunk space to confirm sufficient room for battery and motor placement. Online forums and supplier databases are valuable resources for checking vehicle case studies.
2. Define Performance and Range Requirements
- Motor Power: For daily commuting, choose a motor with 80-120kW; if pursuing original or stronger performance, motors of 150kW and above can provide acceleration experience comparable to or surpassing the original vehicle.
- Battery Capacity: Determines range. Estimate based on daily commuting distance. For example, a 40kWh battery pack typically provides approximately 200 kilometers of comprehensive range on a compact vehicle. Currently, lithium iron phosphate battery packs are the preferred choice for balancing safety and cost.
- Charging: Ensure the kit includes an OBC and plan for home or workplace charging solutions (220V/32A AC charging is basic).
3. Set a Realistic Budget
A complete kit with medium performance and reliable quality currently ranges approximately between $15,000 to $35,000, with the battery pack cost accounting for the highest proportion (about 50%-60%). Be sure to budget for tools, possible auxiliary parts, and professional consultation.
4. Select Reliable Suppliers
Research suppliers with good industry reputation, providing detailed technical support and warranties. Review their past conversion cases, user evaluations, and confirm their components (especially batteries and BMS) comply with international safety standards.
5. Prioritize Compliance and Safety
Before starting, thoroughly understand the regulations in your region regarding modified vehicle road use. For safety, ensure the kit includes complete BMS, high-voltage interlock, insulation monitoring, and physical protection.
Complete Conversion Process Core Steps
Preparation and Removal
Safety first: disconnect the original vehicle battery. Systematically remove the engine, fuel tank, exhaust system, cooling system, and all fuel-related components. Label all wiring harness connectors and properly handle fluids.
Electric System Installation
- Install Motor: Connect the motor to the original vehicle transmission via adapter plate, ensuring precise alignment to avoid vibration.
- Arrange Battery Pack: Securely fix battery modules at designated positions on the chassis or in the trunk, prioritizing vehicle center of gravity balance and crash safety. Connect BMS and cooling lines.
- Integrate Electronic Control System: Install controller, OBC, DC-DC converter (powers 12V system). Connect accelerator pedal sensor, gear shifter (if retained), and cooling pump.
- High and Low Voltage Wiring: Standardize laying of high-voltage orange wiring harnesses, ensure insulation and protection. Modify instrument panel, integrate EV display showing key information such as power level, voltage, temperature, etc.
Testing, Debugging, and Road Testing
Before powering on, conduct thorough insulation and continuity tests with a multimeter. First power-on should be in a safe, open area, gradually testing each system function. Subsequently, conduct low-speed road tests, finely tune controller parameters (such as torque mapping, regenerative braking strength) to ensure vehicle operation is smooth, safe, and efficient.
Cost-Effectiveness Analysis: Conversion vs. Buying New
Conversion Advantages
