Patent Images
1. A battery pack for an electric bicycle including a motor and a motion sensor, the battery pack comprising:
- a battery;
a main switch controlling supply of a power which is supplied from the battery to the electric bicycle; and
a controller, when the electric bicycle abnormally moves in a first direction along which the electric bicycle is forcibly moved and an abnormal motion sensing signal is received from the motion sensor due to the abnormal movement of the electric bicycle, outputting a motor reverse rotation signal to put the motor in a reverse rotation state in which the electric bicycle moves in a second direction opposite to the first direction.

Abstract
Provided is a battery pack for electric bicycle and a control method of the battery pack, and the battery pack may prevent the electric bicycle from moving abnormally. The electric bicycle includes a motor and a motion sensor. The battery pack includes a battery, a main switch and a controller. The main switch controls supply of a power which is supplied from the battery to the electric bicycle. The controller outputs a motor hold signal to put the motor in a hold state, when an abnormal motion sensing signal is received from the motion sensor.

11. A method of controlling a battery pack for an electric bicycle including a motor and a motion sensor, the method comprising:
-
determining whether an abnormal motion sensing signal is received from the motion sensor; and when the electric bicycle abnormally moves in a first direction along which the electric bicycle is forcibly moved and the abnormal motion sensing signal is received by the battery pack due to the abnormal movement of the electric bicycle, outputting a motor reverse rotation signal to put the motor in a reverse rotation state in which the electric bicycle moves in a second direction opposite to the first direction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
