Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Example 1
An intelligent battery compartment, as shown in fig. 1, comprising: battery box assembly 11, status detection module 12 and BMS 13. The state detection module 12 is disposed on the battery box assembly 11, and the state detection module 12 is in communication connection with the BMS 13. Wherein the communication connection is preferably a wired communication connection.
The state detection module 12 is configured to obtain state information of the battery pack assembly 11, and send the state information to the BMS 13.
In this embodiment, the battery box assembly 11 includes a battery box body and a connection mechanism disposed on the battery box body. The specific structures of the battery box body and the connecting mechanism are not limited.
The status information may include information on the location of the battery box assembly 11 on the vehicle.
Wherein, in order to obtain the position information of the battery box assembly 11 on the vehicle, the state detection module 12 is specifically configured to: and acquiring the position information of the battery box assembly 11 on the vehicle according to the stress direction and the stress magnitude detected by the battery box assembly.
Specifically, the state detection module 12 may include a first state detection unit 121, where a sensor head of the first state detection unit 121 is disposed on the connection mechanism.
The first state detection unit 121 may be configured to:
in the process of installing the intelligent battery box to the vehicle, the stress direction and the stress magnitude generated by the connecting mechanism are detected through the sensing head, and if the stress magnitude is larger than a first threshold value and the stress direction is the same as the installation direction of the intelligent battery box, the position information of the battery box assembly 11 on the vehicle is the target position which reaches the installation preset process. The first threshold is a preset experience value.
For example, the bottom of the vehicle is provided with a battery outer case, and the installation preset process may be different according to the structure of the battery outer case in the process of installing the intelligent battery case to the vehicle.
The first installation presetting process is that the battery replacement equipment lifts the intelligent battery box from the lower direction of the vehicle, in the installation presetting process, the installation direction of the intelligent battery box is upward, the target position is set to be the topmost part in the battery outer box, and after the battery box assembly 11 reaches the target position, the intelligent battery box is connected with the battery outer box through a connecting mechanism such as a bolt, a nut and the like and is fixed at the target position. In the process that the power conversion device lifts the intelligent battery box upwards, the first state detection unit 121 detects the stress direction and the stress magnitude generated by the connection mechanism through the sensing head, and if the stress magnitude is greater than a first threshold value and the stress direction is upward, the battery box assembly 11 is indicated to reach the top-most target position in the battery outer box.
The second installation pre-setting process is divided into two stages, the first stage: the power conversion equipment lifts the intelligent battery box from the lower direction of the vehicle; and a second stage: the battery changing device moves the intelligent battery box in front of the horizontal box. In the first stage, the installation direction of the intelligent battery box is upward, and the target position is set to be the topmost part in the battery outer box; in the second stage, the installation direction of the intelligent battery box is horizontal forward, the target position is set to be the foremost end (taking the direction of the head as the front) in the battery outer box, and the intelligent battery box is connected with the battery outer box through a lock shaft or other connecting mechanisms and fixed at the target position after the battery box assembly 11 reaches the target position in the second stage. In the first stage, the first state detecting unit 121 detects the stress direction and the stress magnitude generated by the connection mechanism through the sensor head, and if the stress magnitude is greater than a certain threshold value and the stress direction is upward, the battery box assembly 11 reaches the top-most target position in the battery outer box. In the second stage, the first state detecting unit 121 detects the stress direction and the stress magnitude generated by the connection mechanism through the sensor head, and if the stress magnitude is greater than a certain threshold value and the stress direction is horizontally forward, the battery box assembly 11 reaches the target position at the forefront end disposed in the battery outer box.
The first state detection unit 121 may further be configured to:
after the intelligent battery box is mounted on the vehicle, the stress direction and the stress magnitude generated by the connecting mechanism are detected through the sensing head, and if the stress magnitude is larger than a second threshold value and the stress direction is opposite to the gravity direction, the position information of the battery box assembly 11 on the vehicle is the target position which is reached to the completion of mounting. The second threshold is a preset experience value.
Also taking the first installation preset process as an example, the target position for completion of the installation is set as the topmost part in the battery outer case. After the intelligent battery box is mounted to the vehicle, if the battery box assembly 11 has reached the target position for completion of the mounting, the connection mechanism receives the weight force applied downward by the battery box assembly because the battery box assembly has a certain weight, and in order to support the battery box assembly, the connection mechanism generates upward stress, whereas if the battery box assembly does not reach the target position for completion of the mounting, the connection mechanism does not generate upward stress or even generates stress, the magnitude of the stress is insufficient. Based on this, the sensor head of the first state detection unit 121 is disposed on the connection mechanism, and the stress direction and the stress magnitude generated by the connection mechanism can be detected by the sensor head, so as to determine whether the battery box assembly 11 has reached the target position where the installation is completed, that is, if the stress magnitude is greater than the second threshold value and the stress direction is upward, the battery box assembly 11 has reached the target position where the installation is completed.
Taking the second installation preset process as an example, the target position for completing the installation is set as the top in the vertical direction and the front in the horizontal direction in the battery outer box. After the intelligent battery box is mounted to the vehicle, if the battery box assembly 11 has reached the target position for completion of the mounting, the connection mechanism receives the weight force applied downward by the battery box assembly because the battery box assembly has a certain weight, and in order to support the battery box assembly, the connection mechanism generates upward stress, whereas if the battery box assembly does not reach the target position for completion of the mounting, the connection mechanism does not generate upward stress or even generates stress, the magnitude of the stress is insufficient. Based on this, the sensor head of the first state detection unit 121 is disposed on the connection mechanism, and the stress direction and the stress magnitude generated by the connection mechanism can be detected by the sensor head, so as to determine whether the battery box assembly 11 has reached the target position where the installation is completed, that is, if the stress magnitude is greater than the second threshold value and the stress direction is upward, the battery box assembly 11 has reached the target position where the installation is completed.
Further, the state detection module 12 may further include a second state detection unit 122, where a sensor head of the second state detection unit 122 is disposed on an abutment surface of the battery box assembly 11 and the vehicle. The abutment surface is determined according to an abutment manner of the battery box assembly 11 and the vehicle, and specific abutment manners may be side abutment, top abutment, and the like, and corresponding abutment surfaces may be side surfaces, top surfaces, and the like of the battery box assembly 11.
The second state detection unit 122 is configured to:
after the intelligent battery box is mounted on the vehicle, the stress direction and the stress magnitude generated by the abutting surface are detected through the sensing head, and if the stress magnitude is larger than a third threshold value and the stress direction is along the outward direction of the battery box body, the position information of the battery box assembly 11 on the vehicle is kept at the mounting completion position and is tightly connected with the vehicle. The third threshold is a preset experience value.
For example, after the intelligent battery box is mounted to the vehicle, the front side surface of the battery box assembly 11 abuts against the front inner side surface corresponding to the battery outer box in the vehicle, if the top surface of the battery box assembly 11 abuts against the top inner side surface corresponding to the battery outer box in the vehicle, if the second state detection unit 122 provided on the front side surface of the battery box assembly 11 detects that the stress generated by the front side surface is greater than the corresponding threshold value and the stress direction is in the direction outward (i.e., forward) of the battery box body through the sensor head, and if the second state detection unit 122 provided on the top surface of the battery box assembly 11 detects that the stress generated by the top surface is greater than the corresponding threshold value and the stress direction is in the direction outward (i.e., upward) of the battery box body through the sensor head, the position information of the battery box assembly 11 on the vehicle is kept at the mounting completion position and is tightly connected to the vehicle.
