Electric snowmobile.

Abstract

The main purpose of the project is to convert the snowmobile to electric and make it operational, which rule out focus on factors as ex. driving range, user interface for performance adjustment, heating for comfort, etc.

For mounting the electric motor a suitable and feasible location and motor bracket to easy access the existing gearbox axel, and also in position to a cooling airflow through the hood. The operational design must take into account the RPM at maximum torque for gear ratio and belt speed. Further it is vital to have an on/off switch and a throttle similar to the existing one. This makes the use of a suitable throttle sensor connected to the throttle wire for replacing the carburetor. The direction/neutral switch must be robust, and for easy logical access it will be preferable mounted in the dashboard.

All existing 12 V equipment like headlight, hydraulic braking pump, etc. exclusive the starter and ignition will remain. In addition the converter is also dependent on a 12 V controller supply/circuit, and for mounting of the controller both cooling and shortest possible main wires is crucial for best performance.

The existing instrument panel in the hood will be modified, since the speedometer and the Curtis Spyglass Display are the only two needed and the empty hole of fuel gauge must be covered/closed.

The gas tank will be modified to house the charging socket and charger, for easy physical charging connection access and the position is a central placement between batteries in front and in the saddle. The charger must serve both the power bank batteries and the 12 V battery as a necessity.
