In practical application, only after the function testing device completes the function detection of the tested battery, the charging and discharging test is carried out on the tested battery, and the charging and discharging test is carried out on the battery by controlling the charging and discharging equipment through the function testing device in the application. However, in the present application, the function testing device receives the initial state information of the charging and discharging device fed back by the charging and discharging device in real time, but only after the function testing device completes the function detection of the battery to be tested, it will determine whether to operate the charging and discharging device according to the currently received initial state information of the charging and discharging device.
Step 104: controlling the charging and discharging equipment to perform charging and discharging tests on the battery;

wherein, the operating condition of charge and discharge equipment includes: readiness, normal operation, exception, charge and discharge completion, and fault numbering.
Step 106: and generating a test report according to the working state, the working state parameters and the charging and discharging information.
In the technical scheme provided by the embodiment of the invention, the function test state of the function test device is obtained, the initial state information of the charge and discharge equipment is received, when the function test state is the function test completion, whether the charge and discharge equipment can be operated is judged according to the current state information of the charge and discharge equipment, when the judgment result is yes, the charge and discharge equipment is controlled to carry out charge and discharge test on the battery, the working state information of the charge and discharge equipment and the charge and discharge information of the battery generated in the charge and discharge test process are received, and a test report is generated according to the working state information.
Promptly in this application when function test equipment accomplishes the function test to the battery after, automatic control charge and discharge equipment carries out the charge and discharge test to the battery, compares in prior art needs manual operation function test equipment and charge and discharge equipment's mode, has not only saved manual operation's time, can in time control charge and discharge equipment to test after function test equipment accomplishes the test moreover, has improved the promptness, has further improved efficiency of software testing. Meanwhile, a test report can be generated directly according to the received working state information of the charging and discharging equipment and the charging and discharging information of the battery, and compared with a manual input mode, the time is saved.
Optionally, in another embodiment, step 103 further includes, when the determination result is no, executing step 107;
step 107: generating an alarm signal;
and judging whether the current state information of the charging and discharging equipment is the charging and discharging equipment fault code state information or not.
The alarm signal is used for reminding a user that the current charging and discharging equipment has faults and cannot complete the charging and discharging test, so that the user can process the faults of the charging and discharging equipment.
As shown in fig. 2, which is a flowchart of another battery detection method disclosed in the embodiment of the present invention, the embodiment of the present invention discloses a battery detection method, where step 106 in the method specifically includes:
step 1061: when the working state is charging and discharging completion, abnormity or fault numbering, sending an equipment stop signal to the charging and discharging equipment;
specifically, taking the preset charging and discharging steps as an example, when the preset charging and discharging steps are performed in sequence from the first step to the fifth step, the working state is that charging and discharging are completed.
And when the tested battery is not subjected to a charge and discharge test according to a preset discharge current value (150A), a preset discharge time (30 seconds), a preset charge current value (75A) or a preset charge time (1 minute) in the process of executing the first step to the fifth step, the working state is abnormal. For example, when the discharging step is performed, the discharging step jumps to the third step after 20 seconds of discharging according to the discharging current value of 150A, and the operating state is abnormal.
And when the charging and discharging equipment has faults in the charging and discharging test process, the working state is a fault number. For example, if the CAN communication of the charging and discharging device is abnormal, a fault number 261 is generated, where the fault number is used to identify a location where the charging and discharging device fails.
Step 1062: receiving current charging and discharging information of a battery;
step 1063: and generating a test report according to the working state, the working state parameters and the current charging and discharging information of the battery.
In practical application, the charging and discharging equipment stops two conditions for the charging and discharging equipment of the tested battery in the application, the first condition is that the charging and discharging equipment finishes the measurement of the tested battery according to the preset test steps, the working state information corresponding to the charging and discharging equipment is the charging and discharging completion at the moment, when the function test device receives the working state information fed back by the charging and discharging equipment, a stop signal is sent to the charging and discharging equipment, and the charging and discharging test of the tested battery is finished by the charging and discharging equipment at the moment.
The second situation is that in the process of charging and discharging test, the charging and discharging equipment fails or the tested battery is not measured according to the preset test steps, at this time, the working state information corresponding to the charging and discharging equipment is an abnormal or fault number, when the function test device receives the working state information fed back by the charging and discharging equipment, a stop signal is sent to the charging and discharging equipment, and at this time, although the charging and discharging equipment does not complete the charging and discharging test on the tested battery, the test on the tested battery is also stopped.
In the first case, namely when the test on the tested battery is normally completed, the function testing device generates the test report according to the received current charging and discharging information of the tested battery. Of course, the test report may also include the operating state and the operating state parameters of the charging and discharging device.
The generating of the test report by the function test device according to the received current charging and discharging information of the tested battery specifically includes:
and comparing the current charging and discharging information of the tested battery with the preset charging and discharging working steps, and generating a test report.
After the test report is generated, the charging and discharging equipment is in a standby state, namely the state information of the charging and discharging equipment is ready for standby.
And in the second situation, namely when the charging and discharging equipment does not finish the test on the tested battery, the function testing device generates a test report according to the working state and the working state parameters fed back by the charging and discharging equipment.
Because the charging and discharging detection of the tested battery is not completed, the generated test report may not include the charging and discharging information of the battery, but only include the working state and the working state parameters of the charging and discharging equipment. The test report generated under the condition enables a user to visually see the problems generated in the charging and discharging test process of the charging and discharging equipment. For example, whether the device itself has failed or the battery is not charged or discharged according to a preset test process step, it is further possible to determine which process step is not tested according to a predetermined test process step.
After the test report is generated, the user may take corresponding processing measures according to the content of the test report, for example, when the test report indicates that the charging and discharging device has a fault, the user performs corresponding processing for different faults. After the processing is finished, the charging and discharging equipment is in a standby state, namely the state information of the charging and discharging equipment is ready for preparation.
