Universal Electric Motorization Kit – 4 to 10 kW | QS138 90H + ASI BAC4000 (BATTERY SOLD SEPARATELY)
Easily convert your vehicle into an electric solution for work or leisure!
This complete electric motorization kit is designed to simplify the conversion of off-road vehicles, such as antique snowmobiles (e.g., Ski-Doo Olympique, Élan, or others), for everyday use, whether for work in the maple grove, on your property, or for outdoor activities. This kit can also be used as a stationary motor similar to a Honda GX390 or other motor, but in an electric version, for various applications such as driving hydraulic pumps or other equipment for light or commercial work.
Technical help – Some basic rules
- Autonomy depends on the total energy of the battery, expressed in Wh or kWh (1 kWh = 1000 Wh). It is calculated by Capacity (Ah) × Voltage (V).
- Example: A 72V 10Ah battery = 720 Wh (0.72 kWh).
- Difference between kW and kWh:
- 1 kW = instantaneous power supplied or consumed.
- 1 kWh = total energy consumed or stored.
Example: 1 kW used for 2 hours = 2 kWh (2000 Wh).
Motor power:
- 1 HP ≈ 0.75 kW.
- An engine converts approximately 80% of electrical power into mechanical power.
- Example: 10 kW battery ≈ 8 kW mechanical (~10 HP).
Electric vs. gasoline comparison:
- A 10 kW electric motor can replace a 15 to 20 kW combustion engine thanks to its instant torque and superior efficiency.
- Unlike a gasoline engine, it does not lose energy in transmission and delivers its power immediately, offering better responsiveness and efficiency.
