Flexible step sequences
Charge, discharge and rest phases can be combined into application-specific test sequences.
Charge & Discharge Cycle Test System – Test software for up to 65,535 battery cycles
For repeatable charge and discharge testing with continuous measurement data acquisition.
Reusable configurations and test plans shorten the setup of recurring test campaigns. Protection parameters supervise execution, while start, stop, alarm clearing and communication recovery are controlled centrally from the user interface.
Defined cutoff criteria
Voltage, current, capacity and time are available as step-dependent termination criteria.
Real-time curves
Voltage, current and capacity are presented numerically and graphically while a test is running.
XML import and export
Saved test sequences can be transferred in XML format and reused for subsequent test campaigns.

Charge & Discharge Cycle Test System overview
The Charge & Discharge Cycle Test System controls recurring charge and discharge processes through freely configurable test sequences. Charge, discharge and rest phases can be added, edited, deleted and combined in loops. Appropriate setpoints and termination conditions are assigned to each step. The cycle counter supports 0 to 65,535 repetitions, with 0 enabling continuous operation. During execution, the software displays device status, the active test step, output values, capacity, events and elapsed times. Measurement data can be recorded, viewed as real-time curves and opened later through the data query interface. Test sequences can be exported and reimported in XML format. Communication with the connected power device is configured using its IP address, port and device ID.
Key benefits
Reusable test plans
Sequences can be created, renamed, saved, imported and exported as XML files, simplifying recurring test campaigns.
Step-specific termination
Charge and discharge phases end automatically according to defined voltage, current, capacity or time limits.
Transparent test status
Connection state, output values, operating mode, alarms, sequence step and elapsed time remain visible throughout the test.
Multiple curve views
The interface plots voltage, current and capacity against time, plus voltage and current against capacity.
Controlled data recording
Storage path, file name and acquisition interval are configurable. Recording can be disabled when only live display is required.
Communication recovery
After a device IP change, the dedicated reconnect function enables the software to re-establish communication.
Test workflow and central control
Before a test starts, a saved plan is selected and displayed in a preview. Protection parameters and the required cycle count are defined in the start dialog. The software then processes the selected sequence automatically.
Controlled stop: The stop function terminates the active sequence and switches off all output channels of the connected power device at the same time. Following a device alarm, the alarm state is cleared manually after the cause has been resolved, before the output is restored and the test restarted.
Programmable test steps and limit conditions
| Test step | Programmable values | Termination or timing conditions |
|---|---|---|
| Charge | Charge voltage and charge current | Termination by voltage, current, capacity or time; capacity range from 0.000 to 1,080 Ah. A value of 0 disables the respective condition. |
| Discharge | Discharge current and discharge power | Termination by voltage, capacity or time; capacity range from 0.000 to 1,080 Ah. A value of 0 disables the respective condition. |
| Rest | Duration in hours, minutes and seconds | The total duration of a rest step must not exceed 100 days. |
| Cycle loop | 0 to 65,535 cycles | A value of 0 enables continuous repetition and is also the default setting. |
Measurement data acquisition and analysis
Real-time data
The status panel shows connection and output state, voltage, current, power, capacity, operating mode, alarms, active step and elapsed time.
Historical data records
Saved record files can be opened through the data query interface to review the detailed values recorded during a test.
Curves against time
Voltage, current and capacity curves are plotted against time and updated throughout the test.
Curves against capacity
Additional diagrams plot voltage and current as a function of the recorded capacity.
Typical applications
The software supports recurring battery tests that require defined procedures, clear termination criteria and traceable measurement data.
Charge and discharge characterisation
Charge and discharge phases are applied to the battery under test using suitable setpoints and voltage-, current-, capacity- or time-based termination criteria.
Cyclic endurance testing
Defined sequences are repeated for a specified number of cycles or without a fixed limit while execution is continuously monitored.
Cutoff condition evaluation
The device under test can be operated up to defined voltage, current, capacity or time limits before the relevant step ends automatically.
Recurring test campaigns
Saved configurations and XML test sequences reduce setup effort for equivalent tests and repeated campaigns.
Communication, configuration and data management
| Function | Implementation | Benefit |
|---|---|---|
| Device communication | LAN connection with configurable IP address, port number and device ID | Integration of the connected power device and communication recovery after an IP address change |
| Sequence management | Create, delete, rename, save, XML import and XML export | Consistent test procedures can be saved, transferred and reused. |
| Data recording | Configurable storage path, file name and acquisition interval | Storage can be adapted to the test setup; if no path is entered, files are stored in the application directory under Data/Record. |
| Recording control | Data recording can be enabled or disabled | When storage is disabled, live curves remain available without writing test data to a file. |
| User interface language | English via the “Language” entry in Data/Config.ini; otherwise Chinese | The configured language is loaded the next time the software starts. |
Installation and PC requirements

Protection and safety functions
Overvoltage, overcurrent, overpower, undervoltage and undercurrent limits can be configured for process monitoring. The system initiates protective actions when a limit is exceeded. Device alarms are displayed in the user interface and cleared manually after the cause has been resolved.
Safe system operation:
- Make electrical connections only while the equipment is switched off.
- Connect the power device correctly to protective earth before operation.
- Allow only qualified personnel to operate the system.
- Do not use damaged equipment or perform unauthorised modifications.
Charge & Discharge Cycle Test System FAQ
Sequences support charge, discharge and rest phases, including repeated execution of the configured steps.
The cycle counter ranges from 0 to 65,535. A setting of 0 repeats the sequence continuously.
A charge step can end according to voltage, current, capacity or time. A value of 0 disables the respective condition.
A discharge step can end according to voltage, capacity or time. Current and power are the discharge step setpoints.
Yes. Test sequences can be exported as XML files and imported again when required.
No. Recording can be disabled while real-time curves remain visible.
