Drawings
Fig. 1 is a schematic block diagram of a battery lock according to embodiment 1 of the present invention.
Fig. 2 is a flowchart of a control method of a battery lock according to embodiment 2 of the present invention.
Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The embodiment provides a battery lock, and this battery lock is applicable to the battery of electric motor car and changes, and the battery lock sets up in the electric motor car. The battery lock of the embodiment unlocks the battery when receiving the safety message sent by the external equipment, so that the battery is electrically connected with the electric vehicle. The external device may be a battery replacement device or a battery replacement station.
In this embodiment, the battery lock only unlocks the battery when receiving the safety message, so that the battery is electrically connected with the electric vehicle, and when the user changes the battery privately, the battery lock cannot obtain the safety message, so that the battery installed on the electric vehicle cannot be unlocked, and the electric vehicle cannot run. Therefore, the battery is effectively monitored, and the battery is prevented from being stolen or mistakenly replaced.
Specifically, as shown in fig. 1, the battery lock of the present embodiment includes: a receiving unit 1, a locking unit 2, a transmitting unit 3, an unlocking unit 4 and a storage unit 5. The receiving unit 1 is electrically connected to the locking unit 2, the unlocking unit 4, and the storage unit 5, respectively, and the transmitting unit 3 is electrically connected to the locking unit 2 and the storage unit 5, respectively.
When the electric vehicle exchanges electricity at the electricity exchange station, the electricity exchange equipment of the electricity exchange station detaches the battery from the electric vehicle, and the unlocking mechanism of the battery generates a battery unlocking signal and sends the battery unlocking signal to the battery lock. The battery unlocking signal is used for representing that the battery is detached from the electric vehicle.
When the receiving unit 1 of the battery lock receives a battery unlocking signal, the locking unit 2 is called to lock the battery, so that the battery is electrically disconnected from the electric vehicle, and the electric vehicle cannot normally run at the moment.
After the battery swapping device takes the battery off the electric vehicle, the locking unit 2 further calls the sending unit 3 to send the safety message stored in the storage unit 5 to the battery swapping device (the external device takes the battery swapping device as an example). The safety message is sent by the battery replacement device when the electric vehicle charges the battery at the battery replacement station last time.
And the battery replacement equipment verifies the safety message to determine whether the battery is legal or not. And if the verification is passed, the battery replacing equipment installs the charged battery on the electric vehicle. When it is confirmed that the battery has been mounted on the electric vehicle, the locking mechanism of the battery generates a battery locking signal and sends it to the battery lock. The battery locking signal is used for representing that the battery is installed on the electric vehicle.
And the sending unit 3 of the battery lock sends the acquired battery locking signal to the battery swapping device, and the battery swapping device generates a new safety message and sends the new safety message to the battery lock.
When the receiving unit 1 of the battery lock receives a new safety message, the unlocking unit 4 is called to unlock the battery, so that the battery is electrically connected with the electric vehicle, and the electric vehicle can normally run at the moment.
In this embodiment, the receiving unit 1 further sends the new security message to the storage unit 5 after receiving the new security message, so as to store the new security message. When the electric vehicle exchanges power at the power exchange station again, the battery lock provides the new safety message for the power exchange equipment so as to verify the validity of the battery. And finishing the battery replacement of the electric vehicle.
Example 2
The embodiment provides a control method of a battery lock, and the battery lock is suitable for battery replacement of an electric vehicle. The control method of the embodiment comprises the following steps: the battery lock unlocks the battery when receiving the safety message sent by the external equipment, so that the battery is electrically connected with the electric vehicle. The external device may be a battery replacement device or a battery replacement station.
In this embodiment, as shown in fig. 2, the control method specifically includes the following steps:
and step 101, locking the battery when the battery lock receives a battery unlocking signal.
The battery unlocking signal is used for representing that the battery is detached from the electric vehicle. When the electric vehicle exchanges electricity at the electricity exchange station, the electricity exchange equipment of the electricity exchange station detaches the battery from the electric vehicle, and the unlocking mechanism of the battery generates a battery unlocking signal and sends the battery unlocking signal to the battery lock.
And 102, the battery lock sends the safety message to the battery swapping equipment.
In this embodiment, the external device takes a battery swapping device as an example. And the battery lock sends the safety message to the battery replacement equipment, so that the battery replacement equipment can verify the validity of the battery. The safety message is sent by the battery replacement device when the electric vehicle charges the battery at the battery replacement station last time.
And when the battery replacement equipment passes the verification, the charged battery is installed on the electric vehicle. When it is confirmed that the battery has been mounted on the electric vehicle, the locking mechanism of the battery generates a battery locking signal and sends it to the battery lock. The battery locking signal is used for representing that the battery is installed on the electric vehicle.
And 103, the battery lock sends the acquired battery locking signal to the battery swapping device.
And the battery lock sends a battery locking signal to the battery replacement equipment for the battery replacement equipment to generate a new safety message. And the battery swapping device sends the generated new safety message to the battery lock.
And step 104, the battery lock unlocks the battery when receiving a new safety message sent by the battery replacement equipment.
After the battery lock unlocks the battery, the battery is electrically connected with the electric vehicle, and the electric vehicle can normally run at the moment.
Step 105, the battery lock stores the new security message.
When the electric vehicle exchanges power at the power exchange station again, the battery lock provides the new safety message for the power exchange equipment so as to verify the validity of the battery. And finishing the battery replacement of the electric vehicle.
The battery replacement encryption system of the embodiment realizes effective supervision on battery replacement of the electric vehicle, thereby ensuring that the battery of the battery replacement station (battery replacement operator) circulates in the system of the battery replacement station, avoiding the battery from being replaced by theft and mistakenly, and improving the safety of automobile operation.
