Description

A method, device, terminal, and storage medium for judging battery status

technical field

The invention discloses a method, a device, a terminal and a storage medium for judging the state of a swap battery, and belongs to the technical field of electric vehicles.

Background technique

With the increasing popularity of electric vehicles, the issue of charging speed has become more and more worthy of attention. Affected by the characteristics of the battery, although the charging speed has been slightly increased, the overall charging time at room temperature still lasts for about an hour. In order to improve the user experience, avoid long-term charging waiting, and overcome the anxiety of driving range, the battery replacement mode has become a new choice. In the battery replacement mode, the battery replacement is completed in 3 minutes without waiting.

In the process of repeated battery replacement, there are frequent installation and disassembly of the battery pack. After each installation, the battery pack needs to complete the system self-inspection. After the self-inspection result is fed back to the vehicle, it waits for the vehicle to use. However, after the installation is complete, there is a poor connection or incorrect connection between the replacement battery and the replacement frame. At this time, the battery starts a self-test, and a fault false alarm will occur.

After the above-mentioned false alarm occurs, the maintenance personnel need to lift the vehicle to confirm the problem point because the battery is at the bottom of the vehicle body. The operation is troublesome, the maintenance efficiency is low, and the waiting time of customers is prolonged.

Step S201, obtain the physical connection status and external signal connection status of the replacement battery and the external world respectively, the specific content is as follows:

The status of the physical connection between the replacement battery and the outside world includes but is not limited to the confirmation of the connector status, that is, the interlock signal state, and the confirmation of the connection between the battery pack box and the battery replacement frame, that is, the locking signal state. The status of the connection between the swap battery and external signals includes, but is not limited to, the message status of the swap battery and the vehicle communication network, that is, the communication message status and network node status, and the PWM signal status of the swap battery and the airbag controller, that is, the airbag PWM signal status. .

Step S202, determine the characteristic state of the battery replacement battery according to the physical connection state between the battery replacement battery and the outside world, the specific content is as follows:

Judging whether the state of the interlock signal is intact by obtaining the interlock signal of the high-voltage connector and the low-voltage connector:

Yes, go to the next step to detect the locking mechanism of the battery replacement frame;

No, repeatedly obtain the interlock signal of the high-voltage connector and the low-voltage connector and judge, if at least 5 judgments are all negative, then the characteristic state of the replacement battery is unavailable and report "battery status: battery unavailable" to the VCU Vehicle controller. The unavailable state means that when one of the physical connection states is disconnected, the battery pack is considered to be in an unavailable state. At this time, the signal connection state is not considered, and the battery cannot be used on the vehicle at this time.

The battery swap box and the swap frame must be confirmed by the swap locking mechanism. The detection circuit inside and outside of the battery is all the way to the battery replacement locking mechanism. After the box is installed, the position signal of the battery replacement locking mechanism is obtained to determine whether the locking signal state is completely locked:

Yes, the detection is high level to distinguish the connection state, then the physical connection state detection is completed, and the next step is performed to determine the characteristic state of the battery replacement battery and the connection state of the external signal;

No, it is detected as a low level, not fully locked state, repeatedly obtain the position signal of the battery replacement locking mechanism and judge, if the judgment is no at least 5 times, then the characteristic state of the battery replacement battery is unavailable and reported " Battery status: battery unavailable" to the VCU vehicle controller. The unavailable state has been explained above, so it will not be repeated.

Step S203: Determine the characteristic state of the battery replacement battery and determine whether the self-test can be started according to the connection state of the battery replacement battery and the external signal. The specific content is as follows:

Judging whether it can be identified by obtaining the vehicle communication message:

Yes, it can be recognized normally, go to the next step;

No, repeatedly obtain the vehicle communication message and judge, at least 5 judgments are all negative, then the characteristic state of the battery replacement is the vehicle network failure state and report "battery status: vehicle network status failure" to the VCU vehicle controller . The network failure state of the vehicle is that the connection is confirmed in the physical connection state, but at this time the network message cannot be effectively identified in the signal connection, and the communication cannot be effectively established. At this time, the validity of the PWM of the airbag controller is not considered. device communication, the battery cannot be used on the vehicle.

Judging whether there is a communication error frame by obtaining the vehicle communication message:

Yes, the status of the communication message is normal, go to the next step;

No, the status of the communication message is abnormal. Repeatedly obtain the communication message of the whole vehicle and judge it. If at least 5 times of judgment are all negative, then the characteristic state of the replacement battery is the vehicle network failure state and "battery status: vehicle network status failure" is displayed. The VCU vehicle controller and vehicle network node loss status have been explained above, so I won’t repeat them here.

Determine whether the network node is lost by obtaining the vehicle communication message:

Yes, the network node status is normal, go to the next step;

No, the state of the network node is abnormal, repeatedly obtain the communication message of the vehicle and judge it, if at least 5 judgments are all negative, then the characteristic state of the replacement battery is the lost state of the vehicle network node and report "battery status: vehicle network node lost" For the VCU vehicle controller, the lost state of the vehicle network node is the physical connection state, and the connection is confirmed. During the signal connection, the message can be recognized, but there is a network node lost. At this time, the validity of the PWM of the airbag controller is not considered. At this time, the battery is It can be used on the car, and the lost network node is handled according to the corresponding network node loss fault. When the vehicle controller and motor controller nodes are lost, the battery cannot be used in the vehicle; if other controller network nodes are lost, the battery can realize some functions according to the instructions of the vehicle controller.

Determine whether it is consistent with the design signal state by obtaining the airbag PWM signal detection:

Yes, the PWM signal status of the airbag is normal, and the characteristic status of the replacement battery is a well-connected state. Report "Battery Status: Well-connected" to the VCU vehicle controller, and perform the next step. The well-connected state means that all physical connections and signal connections are confirmed to be normal. At this time, the battery connection is intact and all functions can be used on the car.

No, the state of the airbag PWM signal is abnormal. Repeat the detection and judgment of the airbag PWM signal. At least 5 times the judgment is no. Lost" to the VCU vehicle controller, the airbag controller node lost status is confirmed for physical connection and signal connection, only the PWM signal is invalid. At this time, the battery can be used on the vehicle except for the collision signal detection function, and the battery will report the status to the vehicle controller.

Step S204, if yes, start the self-test and feed back the self-test result to the VCU vehicle controller.

The system self-inspection after the battery characteristic state judgment includes the battery working state, the controller sampling working state, the contactor working state, the sensor working state in the battery pack and so on. Stable, the battery hardware status is stable, and the real status of the battery can be detected.
