The successful PLI series, programmable electronic loads, from H&H is now also suitable for testing intelligent chargers. This by adding the optional Starter Interface (PLI16).

Most intelligent battery chargers do not start the charging process until a suitable battery voltage or output voltage is detected. With the optional starter interface, the PLI series can be used to start a discharge cycle by applying a suitable voltage to the output of the PLI series loads.

This so-called Charger Starter Interface (CSI) can be installed as an option (PLI16) on any model of PLI load with a 60V or 120V voltage range. This battery emulation mode only works in battery charging mode. We start with a suitable charging voltage for the battery charger.  As soon as the charger starts supplying power, the PLI load will follow a pre-programmed voltage profile. This is to simulate the voltage rise of a battery or battery. Throughout the process, voltage and current are measured and stored in the electronic load for further evaluation on reporting.

WHAT OUR CUSTOMERS SAY

ABB

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

Sasan Rafii-Tabrizi

University of Luxembourg

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
