After the instruction of family end, charging instruction is issued to charge-discharge test instrument by server.After charge-discharge test instrument receives server instruction, if
Standby starting, mode setting are charge mode, and electric current is set as specified current flow size (above example script is 100A).Equipment is always
Charge mode is operated in, is charged the battery.
When client reaches specified charging upper limit by communication check to battery charging voltage, (above example script is
4.2V), client issues stopping charging instruction to server.After server receives the stopping charging instruction of client, service
Device issues halt instruction to charge-discharge test instrument.After charge-discharge test instrument receives halt instruction, setting charging current is 0, mould
Formula is to shut down, charge-discharge test instrument orderly closedown.
So far, entire charging measurement process is completed.
In discharge test, server starting, server and battery and charge-discharge test instrument establish communication connection, obtain in real time
Take the operation information of battery information and charge-discharge test instrument.Client terminal start-up, client and server establish communication connection, in real time
Obtain the operation information of battery information and charge-discharge test instrument that server uploads.Client sends electric discharge request to server；
For example, client script：Discharge (100,3.0) // electric discharge interface, is defined on server end, and client inherits server termination
Mouthful, it can directly be used in script, parameter 1 is size of current, and parameter 2 is electric discharge cut-off monomer voltage.Server receives visitor
After the instruction of family end, electric discharge instruction is issued to charge-discharge test instrument by server.After charge-discharge test instrument receives server instruction, if
Standby starting, mode setting discharge mode, electric current are set as specified current flow size (above example script is 100A).Equipment is transported always
Row gives battery discharge in discharge mode.
When client reaches specified electric discharge lower limit by communication check to cell discharge voltage, (above example script is
3.0V), client issues stopping electric discharge instruction to server.After server receives the stopping electric discharge instruction of client, service
Device issues halt instruction to charge-discharge test instrument.After charge-discharge test instrument receives halt instruction, setting discharge current is 0, mould
Formula is to shut down, charge-discharge test instrument orderly closedown.
So far, entire discharge test process is completed.
In temperature test, server starting, server and battery, charge-discharge test instrument, environmental test incubator are established and are led to
Letter connection, obtains battery information, the operation information of charge-discharge test instrument and the operation information of environmental test incubator in real time.Client
Starting, client and server establish communication connection, the fortune of acquisition server uploads in real time battery information, charge-discharge test instrument
The operation information of row information and environmental test incubator.Client issues temperature test instruction to server：For example, client's end feet
This：Temperature (25 DEG C) // incubator interface is set, server end is defined on, client inherits server end interface, can be in script
In directly use, parameter 1 be temperature value；If (battery temperature>=25 DEG C) { setting incubator operating mode (0)；// incubator interface,
It is defined on server end, client inherits server end interface, can directly use in script, and parameter 1 is operating mode, and 0
To shut down }, which is that the temperature of control environmental test incubator is 25 DEG C, when battery temperature reaches 25 DEG C, stops ring
Test incubator operation in border.Server receive client transmission temperature setting order after, server issue temperature setting order to
Environmental test incubator.After environmental test incubator receives the order of server transmission, the starting operation of environmental test incubator controls temperature
For the assigned temperature issued (above example script is 25 DEG C).Client inspection battery temperature, when battery temperature reaches 25 DEG C,
Client issues environmental test incubator to server and stops working instruction.Server receives the environmental test incubator that client issues
After halt instruction, server issues the instruction that stops working to environmental test incubator.Environmental test incubator, which receives, to stop working
After instruction, environmental test incubator stops working.
So far, temperature test process is completed.
The control flow of above charging measurement, discharge test and temperature test is according to client to server to setting
Standby process executes.
When testing battery, other than above charging measurement, discharge test and temperature test, can also adopt
It is tested with other parameters of the other kinds of test equipment to battery, the control flow of other kinds of test equipment can be with
