A multifunctional frame structure is especially suitable for electric snowmobiles. The electric snowmobile includes a frame, an encapsulating body, a driver's seat on top of it, a battery package, front shock absorbers, upper suspension A-arms, lower suspension A-arms, a left and right spindle attached to the respective skis, and vibration isolators between the battery package and the frame. The frame structure is configured for a vehicle structure where a hexahedron-shaped battery package takes a relatively large volume. The frame structure also addresses vibration and shock isolation, in order to allow the vehicle to be used in harsh outdoor conditions.

THERMAL MANAGEMENT OF A BATTERY MODULE AND OF A BATTERY PACK
A thermally controllable battery pack includes a scalable number of battery modules. Each battery module includes a group of horizontally stacked battery cells. Thin metal plate housing surrounds the modules. A thermal fin is placed between some of the adjacent battery cells, so that each battery cell has contact to at least one thermal fin. The thermal fins extend and fold on top of a side edge of the battery cell with 90° angle, so that bent parts of the thermal fins form a substantially planar vertical outer surface. The thermal fins may similarly locate and be bent along the bottom surface. The battery pack includes a foil heater and a thermal pad. A cooling system may include heat exchangers and coolant pipes. A controller and temperature sensor provide thermal management control of the battery pack. The battery pack is used in on-road and off-road electric vehicles.

Vibration and shock isolation has also been thought of, in order to allow the vehicle to be used in harsh outdoor conditions.
The present invention relates to front shock absorbers (4) and related support (i.e. suspension) structures within the frame (9) of an electric snowmobile (1). The structure comprises upper (5) and lower (6) suspension A-arms and a spindle (7) for both skis. A rear connection point (13) for the lower suspension A-arm (6) is placed more to the rear within the frame (9). Also the length of the front shock absorbers (4) is designed to be larger. This design is possible because of more space available in the electrically driven solution. The caster (ß) and camber (a) angles may be kept as constant during any compression magnitude of the front shock absorbers (4).

Snowmobile with an electric motor, and a manufacturing method for a snowmobile with an electric motor
The present invention introduces an electrically driven snowmobile, i.e. an electric sled. The electric motor is applied along the primary driving axis so that its rotational force is applied directly or indirectly to the primary driving axis. The electric motor may locate either inside or outside the frame structure of the snowmobile, and either on the left-hand side or the right-hand side of the primary driving axis. One option of manufacturing the electrically driven snowmobile is to convert a traditional combustion engine driven snowmobile into an electrical one by removing some parts and adding the electric motor within the snowmobile. Another option of manufacturing the electrically driven snowmobile is to build a transmission chain from scratch, and by adding an electric motor along the primary driving axis.
