C8000 Battery Testing System
By all imagination, the Cadex C8000 may well be the most complete and affordable battery testing system available today.
The Cadex C8000 stands in a class by itself in flexibility and affordable price. Test SMBus batteries, monitor cell balance and capture load signatures to observe batteries with a unique load protocol. Add a thermal chamber, an external load bank, a safety circuit and alarm to form a command center and you begin realizing the unique qualities of this fine battery testing system.
- 4 independent digital drivers for maximum flexibility
- 1.2V – 36V, 10A charge and discharge per channel
- 100W per channel on charge; 80W on single channel discharge, 160W dual channel, and 2400W with external load bank
Features
Digital technology widens the test range, provides ultimate stability and gets more power into a compact housing than is possible with analog devices. Each channel can be programmed with up to 10A charge and discharge current each. Power handling is 100W per channel on charge and 80W on discharge, or 400W on charge and 320W on discharge on all four channels. The Cadex C8000 is more than a programmable power supply and load bank; the instrument has intelligence to assist in safe battery testing. Protected charge and discharge algorithms with redundant safety features identify a faulty battery and safely terminate the service should an anomaly occur. The system can be overridden for destructive tests. |

Service Programs
The automated programs are grouped into Basic, Advanced, Rapid-test and Custom programs.
basic Programs
Charge | Applies fast charge; trickle when applicable. |
Auto | Exercises batteries with charge-discharge-charge. Applies recondition on nickel-based batteries to reverse memory if user-set target capacity cannot be reached. |
Prime | Prepares batteries with discharge-charge-discharge by repeated cycling until maximum capacity is reached. The first reading is the spare capacity before charge. |
Extended Prime | 16-hour trickle charge prior to Prime. Prepares difficult to charge batteries |
Boost | Activates batteries that became deactivated due to low discharge. |
Advanced Programs
Load Test | Tests batteries under simulated GSM, CDMA and other discharge protocols, 50μs steps; minimum setting 500μs. |
Runtime | Allows three different discharge levels; programmable in hours and minutes. |
Lifecycle | Cycles battery until the performance drops the target capacity. |
Self-Discharge | Measures self-discharge. Identifies stresses leading to compromised safety. |
Discharge Only | Prepares battery for storage. Also checks charger function. |
Load Capture | Simulates real life conditions with pre-recorded load. Requires PC-BatteryLab™ and Load Capture Unit to record load signature. |
RAPID TESTS
OhmTest™ | Measure battery resistance with DC pulses 13 seconds; based on IEC61436. |
Impedance |
Measures battery resistance with 1000Hz signal. Channel 1 only. Note: Readings of a reactive device differ with DC and AC test methods. |
Custom Programs
These programs allow user-defined settings of charge, discharge, recondition, wait and repeat. You can set conditional gates that proceed on a different course if certain criteria are met. Custom works with PC-BatteryLab™ and has a limit of 100 user-defined programs. One of the critical applications of the custom program is preparing a battery for shipping. You may also want to prepare a battery for storage. Note: Supervision recommended in the absence of automated terminations. |
