Overview

The Battery Load Unit – BLU220T is the stand-alone or a PC-controlled battery capacity test set, based on the state-of-the-art technology. Its design is using the most advanced power electronics solutions with coolers and fans integrated into device itself.

The BLU220T device is lightweight (15,1 kg / 33 lb.) and developed to meet a customer’s wide ranging test procedure requirements (standardized as well as customized). Using the BLU220T device, the capacity test is performed in an accurate, user-friendly way in accordance with the battery testing standards (IEEE 450-2010 / 1188-2005 / 1106-2015, IEC 60896-11/22 and other relevant standards).
Discharging can be performed at constant current, constant power, constant resistance or in accordance with a pre-selected load profile. The discharge test can be conducted even in case a battery remains connected to the load – by measuring the load current during the process.

The BLU220T device provides the discharge current of up to 340 A and may be applied to battery strings with up to 60 V voltage level.

DV-B Win


The DV-B Win software is included in the price, and all its updates are free of charge. Using the DV-B Win software a test can be performed and monitored from a PC, and the results can be saved directly to a PC. Communication between the BLU and a PC is achieved through a USB cable. Using the DV-B Win, the results can be arranged and printed for a report in selectable formats as XLS, PDF, Word, or RTF. Also, a possibility of importing other types of data formats (jpg, png, doc) into standardized DV-B Win report is provided, as well as exporting the numerical and graphical results from the DV-B Win into a customizable report. Additionally, the software provides a possibility of setting extra parameters (cell voltage, string voltage, capacity and time) for alarming and terminating the test.
