EPS/TSDCR Regenerative bidirectional Testsystems 60kW-2,6 MW

Source - Sink - Battery Charger/Tester/Simulator - Inverter - up to 2,6MW/kVA from EPS Stromversorgung

The calibrated EPS/TSDCR test systems from EPS Power Supply are suitable for development-related tests, such as real-time simulation of the vehicle electrical system, simulation of energy storage systems (e.g. LiIon battery simulation), tests of electric drives and fuel cells and their corresponding components, such as inverters, batteries (charging and discharging) and switches. The power range goes up to 650kW in a voltage range from 5 to 1500V and a current range up to 1200A.
For battery tests, the following special conditions also exist. Step cut-off conditions - time, ET, EV, EC, CC time, CV time, mAh, Wh, SOC, cap (%), cap drop, total mAh, total Wh, last mAh, last SOC, last cap (%), last cap drop, last voltage drop DV, +dV/dt, dV/dt, +dT/dt, CB ,ET, CB EH, EXT ET, SBS ET, cell ET, cell EV.

The special feature of these systems is that the electrical energy consumed in generator mode is fed back into the power supply grid with high efficiency. External loads (resistors) are therefore superfluous and electrical energy that would otherwise be "wasted" can be fed back profitably. This regenerative capability is a decisive factor in most test applications, as unusually high power levels are used here.

To increase performance, either a parallel connection (up to 4800A/2,6MW) or a multi-channel system (up to 9600A) is possible. In contrast to conventional DC sources, the multi-channel system has two or four independently usable output channels and can operate as both a source and a sink.

All systems have an electrically isolated output and a TFT touch panel for entering or displaying values and alarms. They can also be controlled via CAN, MODbus TCP, Ethernet, VNC and optionally via HighSpeed/Analog, HighSpeed CAN, Profibus, Profinet and Ethercat. Programming languages are optional: LabView, MatlabSimulink and SCPI.

The system can be freely programmed and has specific algorithms that enable a wide range of tests such as testing solar systems (inverter option), supercapacitors and power factor correction.
Extensive protective measures, such as a standard integrated event memory and a safety controller (level "d") round off the concept.
The system can be "upgraded" according to customer requirements, e.g. with insulation monitoring, DC contactors for disconnection under load (Standard 300/600kW), an additional discharge unit in the event of a power failure (simulator mode), a power distribution unit (PDU), impedance measurement (tester mode) or water cooling (IP54).

The systems are CE-certified and can optionally be adapted in accordance with UL.
