Abstract

A battery pack (10) supplies power to a vehicle (20), and comprises a receiver (11), a signal analyzer (12), and a discharge controller (14). The receiver (11) receives from the vehicle (20) a proper use signal generated by the vehicle (20). The signal analyzer (12) analyzes the proper use signal received by the receiver (11). The discharge controller (14) permits power supply to the vehicle (20) when it has been confirmed, as a result of analysis by the signal analyzer (12), that a proper use signal has been received from the vehicle (20).

First claim

The invention claimed is:

1. A battery pack that supplies power to a vehicle, comprising:
a receiver configured to receive, from the vehicle, a signal generated in the vehicle in response to a starter switch of the vehicle being operated;
a signal analyzer configured to analyze whether the signal received by the receiver is received from the vehicle, or whether a waveform of the received signal matches a waveform of a proper use signal; and
a discharge controller configured to permit power supply to the vehicle in response to determining, as a result of analysis by the signal analyzer, that:
the signal received from the vehicle comprises the proper use signal; or
the waveform of the received signal matches the waveform of the proper use signal.

2. The battery pack according to claim 1 ,
wherein, in response to determining, as a result of analysis by the signal analyzer, that a signal other than a proper use signal has been received, the discharge controller does not supply power to the vehicle.

3. The battery pack according to claim 1 ,
wherein, in response to determining, as a result of analysis by the signal analyzer, that the proper use signal has not been received by the receiver, the discharge controller does not supply power to the vehicle.

4. The battery pack according to claim 1 ,
wherein the proper use signal comprises any of an optical signal, an electrical signal, and a magnetic signal.

5. The battery pack according to claim 1 ,
wherein the proper use signal comprises a digital signal or an analog signal.

6. A battery system, comprising:
the battery pack according to claim 1 ; and
a vehicle comprising a signal generator configured to generate the proper use signal to be transmitted to the receiver of the battery pack, and a transmitter configured to transmit the proper use signal to the receiver.

7. The battery system according to claim 6 ,
wherein the vehicle comprises an electric motorcycle or an electric bicycle.
