Example two
Fig. 2 is a flowchart illustrating a method for determining a battery replacement state, which is used in a terminal according to an exemplary embodiment, and includes the following steps:
step S201, obtaining a physical connection state between the battery replacement battery and the outside and an external signal connection state, respectively, specifically including the following:
the connection state of the battery replacement battery and the outside includes but is not limited to a connector state confirmation, namely an interlocking signal state, and a battery pack box body and the battery replacement frame connection confirmation, namely a locking signal state. The connection state of the battery replacement battery and the external signal includes, but is not limited to, a message state of the battery replacement battery and the vehicle communication network, i.e., a communication message state and a network node state, and a PWM signal state of the battery replacement battery and the airbag controller, i.e., an airbag PWM signal state.
Step S202, determining a characteristic state of the battery replacement through the physical connection state of the battery replacement and the outside, wherein the specific contents are as follows:
whether the interlocking signal state is intact is judged through the interlocking signal who acquires high-pressure connector and low pressure connector:
if yes, executing the next step, and detecting the battery replacement frame locking mechanism;
if not, repeatedly acquiring the interlocking signals of the high-voltage connector and the low-voltage connector and judging, if the judgment is negative for at least 5 times, the battery replacement characteristic state is an unavailable state and reporting a battery state: the battery is unavailable to the VCU vehicle control unit. When one of the unavailable states, namely the physical connection states, is disconnected, the battery pack is considered to be in the unavailable state, and the signal connection state is not considered at the moment, and the battery is unavailable on the vehicle.
The battery replacement locking mechanism is used for confirming the battery replacement battery pack box body and the battery replacement frame. The battery is characterized in that the battery is externally provided with a detection circuit to the battery-replacing locking mechanism, and the battery box is installed completely and then the battery-replacing locking mechanism is used for acquiring a position signal of the battery-replacing locking mechanism to judge whether the locking signal state is a complete locking state:
if the connection state is detected to be high level to distinguish the connection state, the physical connection state is detected, and the next step of connecting the battery replacement battery and an external signal is executed to determine the characteristic state of the battery replacement battery;
if not, detecting the battery replacement state to be a low level, and if the battery replacement state is not completely locked, repeatedly acquiring a position signal of the battery replacement locking mechanism and judging, if the judgment is negative for at least 5 times, judging that the characteristic state of the battery replacement battery is an unavailable state and reporting a battery state: the battery is unavailable to the VCU vehicle control unit. The unusable state is explained above and therefore not described in detail.
Step S203, determining a characteristic state of the battery replacement battery according to a connection state of the battery replacement battery and an external signal, and determining whether self-test can be started, where the specific content is as follows:
whether the communication message of the whole vehicle can be identified is judged by obtaining the communication message of the whole vehicle:
if yes, the next step can be executed after normal recognition;
if not, repeatedly acquiring and judging the communication message of the whole vehicle, if the judgment is negative for at least 5 times, the battery replacement characteristic state is a vehicle network failure state and reporting a battery state: and the vehicle network state is invalid' to the VCU vehicle control unit. The vehicle network failure state is a physical connection state, connection is confirmed, but at the moment, network messages in signal connection cannot be effectively identified, communication cannot be effectively established, the effectiveness of the PWM of the airbag controller is not considered, at the moment, the battery cannot be communicated with other controllers in the vehicle, and the battery cannot be used in the vehicle.
Whether a communication error frame exists is judged by acquiring a vehicle communication message:
if the communication message is normal, executing the next step;
if not, the communication message state is abnormal, the whole vehicle communication message is repeatedly acquired and judged, if the judgment is negative for at least 5 times, the battery replacement characteristic state is a vehicle network failure state and a battery state: the "vehicle network state is failed" to the VCU vehicle controller, and the loss state of the vehicle network node is explained above, so it is not described again.
Judging whether the network node is lost by acquiring the communication message of the whole vehicle:
if the network node is in a normal state, executing the next step;
if not, the network node state is abnormal, the whole vehicle communication message is repeatedly acquired and judged, if the judgment is negative for at least 5 times, the battery replacement characteristic state is a vehicle network node loss state, and a battery state is reported: the vehicle network node is lost to the VCU vehicle control unit, the vehicle network node loss state is a physical connection state, connection is confirmed, messages can be identified in signal connection, but the network node loss exists, the PWM effectiveness of the air bag controller is not considered at the moment, the battery can be used on the vehicle at the moment, and the lost network node is subjected to fault processing according to the loss of the corresponding network node. When the nodes of the vehicle controller and the motor controller are lost, the battery can not be used in the vehicle; other controller network nodes are lost, and the battery can realize partial functions according to the instruction of the whole vehicle controller.
Detecting and judging whether the state is consistent with the state of a design signal by acquiring a PWM signal of the air bag:
if the air bag PWM signal state is normal, the battery replacement characteristic state is a battery state reported by a connection intact state: and (4) the connection is good, and the connection is sent to the VCU vehicle control unit to execute the next step. The good connection state is that all physical connections and signal connections are confirmed to be normal, at the moment, the battery connection is good, and all functions can be used on the vehicle
If not, the air bag PWM signal state is abnormal, the air bag PWM signal is repeatedly obtained for detection and judgment, if the judgment is negative for at least 5 times, the battery replacement characteristic state is an air bag controller node loss state and a battery state is reported: the node loss of the air bag controller is' sent to the VCU vehicle control unit, the node loss state of the air bag controller is that both physical connection and signal connection are confirmed, and only PWM signals are invalid. At the moment, the battery can be used on the vehicle except for the collision signal detection function, and the battery reports the state to the vehicle control unit.
And S204, if yes, starting self-checking and feeding back a self-checking result to the VCU vehicle control unit.
The system self-check after the characteristic state of the battery is judged comprises the check of the working state of the battery core, the working state of the controller sampling, the working state of the contactor, the working state of the sensor in the battery pack and the like, under the characteristic state of the battery, the battery is connected perfectly, the power supply in the self-check process of the controller is stable, the hardware state of the battery is stable, and the real state of the battery can be detected.
The method and the device have the advantages that the accurate judgment of the connection state of the battery and the outside is realized, the false alarm of the self-checking fault of the battery replacement system can be effectively reduced, and the false alarm of the battery fault after the battery replacement of the vehicle is avoided, so that the customer experience is caused; meanwhile, according to the method provided by the invention, the battery state can be accurately judged, and if the connection problem of the battery replacement battery and the outside exists, the fault point can be accurately positioned, the problem troubleshooting time is reduced, and the maintenance efficiency is improved.
