Battery Testing: New power supply unit for tests on cell level…
With our new 4 quadrants power supply unit we are able to perform deep discharge with a constant current up to 1000A into the negative voltage range.
Furthermore, we can simulate fast load change with millisecond precision, as well as challenging current profiles between + 1000 and -1000 A.
constant current mode: -10 to +10 V / -1000A to+1000A
constant voltage mode: 0 to +10V / -1000A to +1000A
Thus, the power supply unit is particularly appropriate for the following cell tests (also, because of its fast switch times):
- Deep discharge
- Cyclizing with high current
- Cyclizing within defined voltage limits
- Propagation tests
