Description:
The BPTS 20920-720 provides a powerful system for high capacity battery pack testing. The system works as a cycler device which can perform the function of charging and discharging. In discharge mode the device is regenerative and feeds the energy back into the local grid with an efficiency up to 96.5%. The DC power of 180 kW, the DC voltage of 0 - 920 V and the DC current of 0 - 720 A is tailored for the testing of high capacity battery packs. The system is equipped with a DC contactor on each pole (one in DC+ and one in DC-) to clearly separate the battery pack from the system and to enable additional, useful functionalities. These include the active pre-charge, the reverse polarity detection and the zero current turn off functionality. In addition, the system has a temperature input to monitor the temperature of the battery pack under test and to stop the test if the battery pack becomes too hot. The system is installed with a high density into a 42U rack that has a width of only 600 mm and a depth of 1000 mm. The Rack has one AC input and is equipped with a 2 channel fast stop system to shut down the rack in emergency situations. The fast stop button is placed on the front of the door and the rear door is secured by door contact switches. Once the rear door opens during operation the fast stop system will be activated automatically. Also, the DC contactors are integrated into the fast stop system and disconnects the pack tester from the battery pack under test. |
