Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1, the battery swapping encryption system includes an encryption device 12; the encryption device 12 is used for receiving the reloading completion signal and setting the reloading legal signal after receiving the reloading completion signal; the reloading completion signal is used for representing that the battery reloading of the electric vehicle is completed in a legal battery reloading mechanism; the encryption means 12 is also arranged to store the reloading legitimacy signal.
When a user moves the electric vehicle to a battery replacement station (namely a legal battery replacement operation mechanism) for battery replacement, after the battery replacement is finished, an external device 1 arranged in the battery replacement station sends a replacement finishing signal, the replacement finishing signal represents that the operation of replacing the battery is legal battery replacement operation performed in the battery replacement station, and the battery installed on the electric vehicle is a battery of a regular channel. The encryption device sets the reloading valid signal (for example, sets the reloading valid signal to "1") after receiving the reloading completion signal. The encryption device stores a replacement legal signal, and the set replacement legal signal represents that the current battery replacement is legal battery replacement operation.
If the user does not change the battery at the battery changing station but the battery is replaced by private, the encryption device 12 cannot receive the signal of finishing the replacement after the replacement, and the signal of legal replacement is reset by the encryption device 12, and the state is '0'. The encryption device 12 stores a replacement legal signal, and the reset replacement legal signal represents that the replacement is illegal replacement operation.
The state of the reloading legal signal can represent whether the electric vehicle carries out reloading operation legally (namely, conforms to the reloading operation specification). If the reloading legal signal is set and the state is '1', the electric vehicle is indicated to be subjected to legal reloading operation, and the battery mounted on the electric vehicle is a battery in a normal channel; if the reloading legal signal is reset and the state is '0', the condition indicates that the electric vehicle carries out illegal reloading operation, and the battery installed on the electric vehicle is probably stolen to be changed into a poor battery. Whether the reloading operation of the electric vehicle is legal or not can be effectively identified through the state of the reloading legal signal, so that the circulation of the battery is monitored. If the electric vehicle is found to have a private power swapping behavior which does not conform to the power swapping operation specification, the power swapping station can take corresponding measures, for example, claim compensation and the like.
Example 2
On the basis of the battery swapping encryption system in embodiment 1, referring to fig. 2, the battery swapping encryption system in this embodiment further includes a battery swapping monitoring device 11, and the encryption device 12 is in communication connection with the battery swapping monitoring device 11; when the electric vehicle is powered again, the power replacement monitoring device 11 is used for detecting whether the power replacement legal signal is set. In the present embodiment, the encryption device 12 and the battery replacement monitoring device 11 are connected through a 4G (fourth generation mobile communication technology) network communication.
After each reloading, the encryption device stores the reloading legal signal, and as mentioned above, the state of the reloading legal signal can represent whether the electric vehicle carries out legal reloading operation or illegal reloading operation. When the electric vehicle arrives at the battery replacement station again for battery replacement, the battery replacement monitoring device 11 reads the replacement legal signal stored in the encryption device 12, and detects whether the replacement legal signal is set. If the reloading legal signal is in a set state (1), the reloading operation before the electric vehicle is legal, the battery installed on the electric vehicle is a battery of a normal channel, and the battery can be replaced for the electric vehicle by the battery replacing station; if the replacement legal signal is in a reset state (0), the replacement legal signal indicates that the previous replacement operation of the electric vehicle is illegal, the battery installed on the electric vehicle is probably not a battery of a regular channel, and the replacement station can check the battery accordingly, and if the replacement legal signal confirms that the battery is a poor battery which is replaced privately, the replacement station can claim compensation for a user.
Example 3
On the basis of the embodiment 2, referring to fig. 3, the encryption device 12 of the battery swapping encryption system of the embodiment is further configured to obtain a battery unlocking signal beta _ unlock, where the battery unlocking signal beta _ unlock is used to represent that a battery pack is detached from an electric vehicle; the encryption device 12 is also used for resetting the reloading legal signal after receiving the battery unlocking signal. The electric vehicle is provided with a mechanism for detecting the installation state of the battery, once the battery is detached, the mechanism sends a battery unlocking signal beta _ unlock, and the encryption device resets the reloading legal signal after receiving the battery unlocking signal.
The encryption device is further used for acquiring a battery locking signal beta _ lock, and the battery locking signal beta _ lock is used for representing that the battery pack is installed on the electric vehicle; the encryption device is also used for setting the reloading legal signal after receiving the battery locking signal and the reloading completion signal. When the battery is installed in place, the mechanism for detecting the installation state of the battery sends a battery locking signal beta _ lock. The encryption device receives a battery lock signal beta _ lock.
If the current battery replacement is completed in a legal and regular battery replacement station, the encryption device 12 also receives a signal of completion of the battery replacement within a preset time (the preset time can be set as required), and the encryption device 12 sets a signal of legal battery replacement after receiving the battery locking signal and the signal of completion of the battery replacement.
If the encryption device does not receive the reloading completion signal within the preset time after receiving the battery locking signal beta _ lock, the situation that the electric vehicle has the battery replacing operation is shown, the battery is detached, the battery is installed on the electric vehicle, but the battery replacing operation is not completed in a normal battery replacing station, and therefore the encryption device does not receive the reloading completion signal, and the encryption device resets the reloading legal signal.
The battery replacement monitoring device 11 reads the replacement legal signal stored in the encryption device 12, and detects whether the replacement legal signal is set. If the reloading legal signal is in a set state (1), the reloading operation before the electric vehicle is legal, and the battery installed on the electric vehicle is a battery of a normal channel; if the reloading legal signal is in a reset state (0), the reloading operation before the electric vehicle is illegal.
For the user who performs illegal and private battery swapping, the battery swapping encryption system of the embodiment provides a remedial measure. Referring to fig. 3, the swapping encryption system of this embodiment further includes a password request unit 13, a password verification unit 14, and a decryption unit 15; the password verification unit 14 is in communication connection with the encryption device 12; the password request unit 13 is used for sending a password request signal to the decryption unit 15 when the reloading legal signal is reset; the decryption unit is used for sending out a password; the password verification unit 14 is used for receiving a password; the password verification unit 14 is further configured to verify the password, and send a verification success identifier to the encryption apparatus after the password is successfully verified; the encryption device is also used for setting the reloading legal signal after receiving the verification success identification.
The decryption unit 15 is provided at a customer service center of the battery replacement station (in another alternative embodiment of the present invention, the decryption unit is provided at an operation center of an operator of the electric vehicle). When the user realizes that the private battery swapping behavior does not accord with the battery swapping operation specification or belongs to a default behavior, and the user wants to install the battery in a regular channel back to the electric vehicle again, the user can use the password request unit to send a password request signal to the decryption unit, for example, dialing a customer service telephone of a battery swapping station, explaining the private battery swapping condition to a customer service center, and requesting the customer service center to provide an unlocking password. The customer service center records the information (license plate number, battery number and the like) of the electric vehicle and records the private power change behavior (if necessary, a power change station sends a worker to the site for confirmation). The customer service center is provided with a decryption unit 15 which can generate an unlocking password, and the customer service center provides the unlocking password for the user in the form of short messages and the like. The password verification unit receives the unlocking password, verifies the unlocking password according to a preset algorithm, and sends a verification success identifier to the encryption device after the password is successfully verified; and the encryption device sets the reloading legal signal after receiving the verification success identifier. If the password verification fails, the reloading legal signal keeps a reset state.

step S402, the encryption device stores the reloading legal signal.
When a user moves the electric vehicle to a battery replacement station (namely a legal battery replacement operation mechanism) for battery replacement, after the battery replacement is finished, an external device arranged in the battery replacement station sends a replacement finishing signal, the replacement finishing signal represents that the operation of replacing the battery is legal battery replacement operation carried out in the battery replacement station, and the battery mounted on the electric vehicle is a battery of a regular channel. The encryption device sets the reloading valid signal (for example, sets the reloading valid signal to "1") after receiving the reloading completion signal. The encryption device stores a replacement legal signal, and the set replacement legal signal represents that the current battery replacement is legal battery replacement operation.
If the user does not change the battery in the battery changing station but the battery is replaced by private, the encryption device cannot receive the signal of finishing the replacement after the replacement, and the legal signal of the replacement is reset by the encryption device, and the state is '0'. The encryption device stores a replacement legal signal, and the reset replacement legal signal represents that the replacement is illegal replacement operation.
The state of the reloading legal signal can represent whether the electric vehicle carries out reloading operation legally (namely, conforms to the reloading operation specification). If the reloading legal signal is set and the state is '1', the electric vehicle is indicated to be subjected to legal reloading operation, and the battery mounted on the electric vehicle is a battery in a normal channel; if the reloading legal signal is reset and the state is '0', the condition indicates that the electric vehicle carries out illegal reloading operation, and the battery installed on the electric vehicle is probably stolen to be changed into a poor battery. Whether the reloading operation of the electric vehicle is legal or not can be effectively identified through the state of the reloading legal signal, so that the circulation of the battery is monitored. If the electric vehicle is found to have a private power swapping behavior which does not conform to the power swapping operation specification, the power swapping station can take corresponding measures, for example, claim compensation and the like.
Example 5
The embodiment provides a battery swapping encryption method, which is implemented by using the battery swapping encryption system in embodiment 2. Referring to fig. 5, the battery swapping encryption method includes the following steps:

After each reloading, the encryption device stores the reloading legal signal, and as mentioned above, the state of the reloading legal signal can represent whether the electric vehicle carries out legal reloading operation or illegal reloading operation. When the electric vehicle arrives at the battery replacement station again for battery replacement, the battery replacement monitoring device reads the battery replacement legal signal stored by the encryption device and detects whether the battery replacement legal signal is set. If the reloading legal signal is in a set state (1), the reloading operation before the electric vehicle is legal, the battery installed on the electric vehicle is a battery of a normal channel, and the battery can be replaced for the electric vehicle by the battery replacing station; if the replacement legal signal is in a reset state (0), the replacement legal signal indicates that the previous replacement operation of the electric vehicle is illegal, the battery installed on the electric vehicle is probably not a battery of a regular channel, and the replacement station can check the battery accordingly, and if the replacement legal signal confirms that the battery is a poor battery which is replaced privately, the replacement station can claim compensation for a user.
Example 6
The embodiment provides a battery swapping encryption method, which is implemented by using the battery swapping encryption system in embodiment 3. Referring to fig. 6, the specific process of the battery swapping encryption method is as follows:
in the initial state, no power switching operation occurs, the encryption device is in a standby state, and at the moment, the replacement legal signal is in a set state, which indicates that no illegal private power switching behavior occurs.
The electric vehicle is provided with a mechanism for detecting the installation state of the battery, and in the process of replacing the battery, once the battery is detached, the mechanism sends a battery unlocking signal, and the encryption device resets a replacement legal signal after receiving the battery unlocking signal.
When the battery is mounted on the electric vehicle again, the mechanism for detecting the mounting state of the battery then sends out a battery locking signal, and the encryption device receives the battery locking signal. If the battery replacement is completed in a legal and regular battery replacement station, the encryption device also receives a signal of the completion of the battery replacement within a preset time (the preset time can be set as required), and the encryption device sets a legal signal of the battery replacement after receiving a battery locking signal and the signal of the completion of the battery replacement. If the encryption device does not receive the reloading completion signal within the preset time after receiving the battery locking signal, the situation that the electric vehicle has the battery replacing operation is shown, the battery is detached, the battery is mounted on the electric vehicle, but the battery replacing operation is not completed in a regular battery replacing station, so that the encryption device does not receive the reloading completion signal, and the encryption device resets the reloading legal signal.
For the user who performs illegal and private battery swapping, the battery swapping encryption method of the embodiment provides a remedial measure. When the user realizes that the private battery swapping behavior does not conform to the battery swapping operation specification or belongs to a default behavior, and the user is willing to install the battery in a regular channel back to the electric vehicle again, the user can use the password request unit to send a password request signal to the decryption unit, and the decryption unit is arranged in a customer service center of the battery swapping station (in other optional embodiments of the invention, the decryption unit is arranged in an operation center of an operator of the electric vehicle). For example, the user can dial a customer service telephone of the battery replacement station, explain the condition of replacing batteries privately to the customer service center, and request the customer service center to provide an unlocking password. The customer service center records the information (license plate number, battery number and the like) of the electric vehicle and records the private power change behavior (if necessary, a power change station sends a worker to the site for confirmation). The customer service center is provided with a decryption unit which can generate an unlocking password, and provides the unlocking password for the user in the form of short messages and the like. The password verification unit receives the unlocking password, verifies the unlocking password according to a preset algorithm, and sends a verification success identifier to the encryption device after the password is successfully verified; and the encryption device sets the reloading legal signal after receiving the verification success identifier. If the password verification fails, the reloading legal signal keeps a reset state.
The battery replacement monitoring device reads the replacement legal signal stored in the encryption device and detects whether the replacement legal signal is set. If the reloading legal signal is in a set state (1), the reloading operation before the electric vehicle is legal, and the battery installed on the electric vehicle is a battery of a normal channel; if the reloading legal signal is in a reset state (0), the reloading operation before the electric vehicle is illegal.
The battery replacement encryption system and method can detect whether the battery replacement behavior of a user meets the operation specification, and the battery replacement station can conveniently confirm whether the battery on the electric vehicle is replaced in a regular channel, so that the battery of the battery replacement station is ensured to circulate in the system of the battery replacement station, and loss is avoided; for illegal and private battery replacement behaviors, the battery replacement station can also find out in time to perform compensation.
