Converting a Renault Express Pickup from internal combustion to electric power is an exciting project, and selecting the motor, the “new heart” of the vehicle, is crucial as it directly determines the core performance post-conversion. It replaces the original internal combustion engine, efficiently converting electrical energy from the battery pack into mechanical energy to drive the wheels, profoundly impacting the vehicle’s acceleration, load capacity, and top speed.
When choosing a motor for the Renault Express Pickup, focus on the following technical parameters to ensure it meets daily use and load requirements:
Key Selection Criteria:
-
Peak Power & Torque: The recommended target is a minimum of 100 kW and 300 Nm of torque. This combination will provide this compact pickup with power that matches or exceeds the original 1.6L diesel engine (approx. 48-55 kW), ensuring ample power reserve for fully loaded starts or hill climbs.
-
Speed Range: Opt for a motor with an operational speed range between 6,000 and 12,000 rpm. A broad constant power range enables sustained and stable power output across various speeds, adapting to multiple driving scenarios like city streets and highways.
-
Voltage Compatibility: Choose a motor compatible with 300-400V high-voltage systems. This is the standard voltage for mainstream EV platforms, facilitating compatibility with mature battery packs and electronic control products on the market for higher efficiency and better range.
-
Cooling System: For a pickup that may face high-intensity, fully loaded operation, a liquid-cooled system offers more efficient and stable thermal management compared to air-cooling. This ensures the motor maintains optimal performance during prolonged operation and extends its service life.
-
Physical Dimensions: The motor’s physical size must fit within the vehicle’s original engine bay. The Renault Express Pickup has a compact engine compartment, so choosing a structurally compact motor can minimize modifications to the vehicle’s body, simplifying installation and reducing costs.
Integration Solution Recommendations:
The Renault Express Pickup was primarily equipped with a manual gearbox, which offers a relatively straightforward path for electrification:
-
For Manual Gearbox Vehicles: The simplest integration method is to directly connect the motor’s output shaft to the vehicle’s existing manual gearbox via an adapter plate. This allows you to retain the original gearbox, driveshaft, and shifting lever, preserving the familiar driving experience. It is one of the most cost-effective solutions with the fewest steps.
-
For Automatic Gearbox Vehicles (if applicable): If your model is equipped with an automatic transmission, a direct-drive solution can be employed. This involves removing the original transmission and connecting the motor directly to the driveshaft via a custom coupling. This solution offers a simpler structure and higher efficiency but typically requires precise calibration of the motor controller to simulate gear-shifting functions.
For reliable results, it is advisable to consult successful electric conversion cases of other light commercial vehicles (e.g., Volkswagen Caddy, Fiat Doblò) and select motor brands that can provide local technical support and complete integrated solutions.
