It is designed for high current load tests of automotive batteries in a production line. A movable frame houses the water cooling unit, the master control unit and up to 6 CHL500 power stage modules of 500 A each in one rack. A 15-inch touch panel for test program set-up and the profile editor can be mounted at the machine.
Yes. The performance is scalable by adding modules at any time, up to 6 modules in one rack. Each CHL500 module covers a discharge current range of 5 A to 500 A at a nominal discharge voltage of ±3 to 12 V DC.
At the end of a test sequence, the different test criteria are compared on the basis of statistically determined comparison data, and the results are rated ACCEPTED or FAILED. The average value and the standard deviation of the open circuit voltage and the high current voltage are calculated from all accepted batteries, which allows a better evaluation of the whole batch. The control software is described in a separate data sheet on the End-of-Line Test E-Load and Software page.
The rack is supplied with 400 V, 50/60 Hz AC and has a closed water cooling circuit with water-glycol. DC current is connected via M12 bolts, and the master control unit communicates externally via Ethernet. The system measures approx. 865 × 1066 × 1565 mm (L × W × H) and weighs up to 500 kg, depending on the number of power stages. It is designed for ambient temperatures of 10 °C to 40 °C, above 40 °C with power derating.
