System processing software |
Expandability |
- Minimum (a few CH to 100 CH) to maximum (500 CH ~ 1000 CH) due to LAN construction
- The number of CH can be increased through adding to the memory capacity around the PC.
- Through connecting to higher level communication lines, diverse system control and data control can be achieved.
|
| Processing speed |
- Within each unit, current capacity and power capacity are calculated in each case and the resulting data are stored in the server via the LAN. Since no time is taken for graph and table creation, it is possible to graphically display and tabulate the results of charging/discharge in extremely real time. |
| Charging/Discharge high-speed sampling |
- For use with electric double layer capacitor charging/discharge test mode (sampling resolution: 2ms, 0.1ms (under development))
- Support possible CP/CR5ms (control period) |
| Platform |
Microsoft Windows 2000 and subsequent versions |

Operability |
Charging/Discharge mode |
Testing of both charging and discharge can be performed by optionally combining steps from CC, CC-CV, CP, CR and idle (10 steps x 50 patterns). |
| Pulse charging/discharge |
Fitted with pulse charging/discharge mode able to simulate load of mobile phone or note PC batteries (CC/CP/PWM). Minimum pulse width 400μs. (Data is incorporated every second). |
| Report printing |
Test results are compiled into formatted reports.
Printing is performed upon deciding the display format, i.e. test conditions, charging/discharge curve, cycle characteristics graph, charging/discharge capacity, etc.
|
| Measurement reference electrode |
Through resting a number of CH inside a unit, it is possible to obtain data on the medium point potential.
Unit can be supplied with a dedicated measurement reference electrode (OP) |
| CH independent control |
Independent test condition setting and test advancement is possible according to each CH. |
| Graphs |
Can handle various types of graphs (for example, display of dQ/dV characteristics) |
| Tabulation |
Capacity characteristics and IR values, etc. can be outputted according to each charging/discharge mode and cycle. |
| Text file |
Graph and tabular data can be outputted in CSV format.
Optional analysis can be performed through using commercially available spreadsheet software |
| Abnormality notification |
Abnormalities can be notified to users via e-mail (OP) |

Maintenance |
Unit replacement |
Since each unit is independently composed, maintenance can be performed through exchanging units. |
| 7 |
Current |
Range switching (current) |
3 types, i.e. single range, 2-stage auto-range, and large and small 2 range x 3-stage auto-range |
| Digit reading |
4~5 digits |
| Voltage range |
Various type are available over the range of 5V ~ 25V |
| Current range |
Various type are available over the range of 10μA ~ 200A |
| When using mixed current values |
When using the charging/discharge module M02, the mixed use of differing
current values is possible.
Example: 5A-3CH, 3A-5CH, 200mA-10CH, 10μA-10CH. |

Charging/Discharge calibration |
Securing of safety |
High level stability is secured through eliminating all variable resistors and adopting stable resistors. |
| Automatic calibration |
- Through using automatic calibrators, automatic correction is performed and highly accurate calibration results can be obtained.
- Since automatic calibration sets can be leased out, users can freely schedule calibration according to their own needs.
- Calibration required time: Around 2 hours/100CH
- Securing of traceability |

Battery pack charging/discharge |
|
- Through individually managing the voltage and varying the temperature conditions of five directly connected batteries, it is possible to recreate actual operating conditions and measure data. (For use with virtual packs) |
