Abstract
An electric snowmobile having: a frame having a tunnel; a seat; at least one ski; a drive track; an electric motor; a battery pack; a charger; a cooling and heating system; and a temperature sensor. The cooling and heating system has: a valve having an inlet, and first and second outlets; a heat exchanger connected to the tunnel or defining part of the tunnel, the heat exchanger being fluidly connected to the first outlet; a heater fluidly connected to the second outlet; and a pump fluidly connected to the inlet. In a first position of the valve; the first outlet is open; and the second outlet is closed. In a second position of the valve; the first outlet is closed; and the second outlet is open.
Claims18
An electric snowmobile comprising:
- a frame having a tunnel;
- a seat connected to the tunnel;
- at least one ski operatively connected to the frame;
- a drive track disposed at least in part under the tunnel;
- an electric motor supported by the frame, the electric motor being operatively connected to the drive track;
- a battery pack connected to the frame and electrically connected to the electric motor;
- a charger electrically connected to the battery pack;
- and
- a cooling and heating system comprising:
- a valve having an inlet, a first outlet and a second outlet;
- a heat exchanger connected to the tunnel or defining part of the tunnel, the heat exchanger being fluidly connected to the first outlet of the valve;
- a heater fluidly connected to the second outlet of the valve;
- and
- a pump fluidly connected to the inlet of the valve for causing coolant flow through the cooling and heating system;
- and
- a temperature sensor for sensing a temperature of coolant in the cooling and heating system;
- in a first position of the valve:
- the first outlet of the valve being open;
- the second outlet of the valve being closed;
- and
- coolant pumped by the pump flowing:
- from the valve to the heat exchanger,
- from the heat exchanger to the charger, the battery pack and the electric motor, and
- from the charger, the battery pack and the electric motor to the valve;
- in a second position of the valve:
- the first outlet of the valve being closed;
- the second outlet of the valve being open;
- and
- coolant pumped by the pump flowing:
- from the valve to the heater,
- from the heater to the battery pack and the electric motor, and
- from the battery pack and the electric motor to the valve.
