Abstract

A battery box for an electric cycle includes a battery and a case enclosing the battery. The case includes an air inlet and an air outlet in communication with the air inlet for directing air flow through the case to cool the battery. An adjustable vent is disposed at the air outlet for deflecting the air flow from the air outlet in a selected direction, such as toward an occupant of the electric cycle.

First claim

What is claimed is:

1. A battery box comprising:
a battery;
a case enclosing the battery and including an air inlet and an air outlet in communication with the air inlet for directing air flow through the case to cool the battery; and
an adjustable vent disposed at the air outlet for deflecting the air flow from the air outlet in a selected direction;
a fan disposed in the case for forcing air flow from the air inlet to the air outlet;
a controller in communication with the fan and a temperature sensor in communication with the controller; and
a heating element disposed in the case and in communication with the controller.

2. The battery box as set forth in claim 1 wherein the adjustable vent includes a frame and a vane pivotally connected to the frame for directing the air flow.

3. The battery box as set forth in claim 2 further comprising another vane pivotally connected to the frame transverse to the vane.

4. The battery box as set forth in claim 1 further comprising an additional air outlet defined by the case in communication with the air inlet, and a baffle in communication with the additional air outlet for opening and closing the additional air outlet.

5. The battery box as set forth in claim 1 wherein the case is configured to be mounted to the frame of an electric cycle.

6. The battery box as set forth in claim 1 further comprising a heat sink in communication with the battery and an air passage extending from the air inlet to the air outlet and extending across the heat sink.

7. The battery box as set forth in claim 1 further comprising a motor controller programmed to control a motor of an electric cycle.

8. The battery box as set forth in claim 1 wherein the controller is programmed to supply power from the battery to the heating element.

9. An electric cycle comprising:
a frame defining an occupant region configured to be occupied by an occupant;
a battery box supported by the frame and including a battery and a case enclosing the battery;
the case including an air inlet and an air outlet, the air outlet being in communication with the air inlet and facing the occupant region for allowing air flow from inside the case toward the occupant region; and
a controller in communication with the fan, a temperature sensor disposed in the case and in communication with the controller, and a heating element disposed in the case and in communication with the controller.

10. The electric cycle as set forth in claim 9 further comprising an adjustable vent disposed at the air outlet for deflecting the air flow from the air outlet in a selected direction.

11. The electric cycle as set forth in claim 10 wherein the adjustable vent includes a frame and a vane pivotally connected to the frame for directing the air flow.

12. The electric cycle as set forth in claim 11 further comprising another vane pivotally connected to the frame transverse to the vane.

13. The electric cycle as set forth in claim 10 further comprising an additional air outlet in communication with the air inlet and facing the occupant region, and a baffle in communication with the additional air outlet for opening and closing the additional outlet.

14. The electric cycle as set forth in claim 9 wherein the air inlet faces away from the occupant region for intaking air as the electric cycle moves forward.

15. The electric cycle as set forth in claim 9 further comprising a heat sink in communication with the battery and an air passage extending from the air inlet to the air outlet and extending across the heat sink.

16. The electric cycle as set forth in claim 9 further comprising a fan disposed in the case for forcing air flow from the air inlet to the air outlet.

17. The electric cycle as set forth in claim 9 further comprising a motor and a controller disposed in the case programmed to control the motor.

18. The electric cycle as set forth in claim 9 wherein the controller is programmed to supply power from the battery to the heating element.
