The battery discharger will allow a controlled discharge of the battery while analyzing the voltage and discharge current. Being the most common constant current discharge, the equipment is programmed for constant current discharge precisely while keeping the battery voltage under control. After the test is complete, thanks to its data download port, the user will be able to generate a report on the status of the battery capacity.
The BDX is an automatic battery discharger/analyzer, designed to test the efficiency of industrial batteries of any type, voltage, and capacity.
This equipment can be programmed to discharge the battery with a precisely controlled constant current, adjustable from zero to the maximum rated value, while keeping the battery voltage under control.
While the discharge is in progress, the control board measures the total capacity (Ampere-Hours) discharged from the battery. When the battery voltage reaches the minimum programmed value, or when the maximum programmed test time is reached, the BDX shuts down automatically, while the measured parameters remain available to the user.
The BDX is very simple to use and does not require training. The programming of the test requires less than 2 minutes and the operation is completely automatic.
An active circuit prevents any arcing between the connectors when the battery is being connected. If a battery relates to reverse polarity, the BDX does not start and no current flows.
When the BDX is powered, an automatic test of the control logic and power electronics is performed in less than 10 seconds. In case of components failures, the BDX remains in a safe, stand-by mode.
While the discharge is in progress, it is not necessary to leave a PC always connected to the BDX, because the integrated Data Logger has enough memory to save the entire discharge curve. At the end of the test, it is possible to download the data from the BDX to the PC in seconds. The standard connection interfaces are serial (RS-232) and USB. Wireless interfaces are available on request.
TrendCOM is a powerful, dedicated software that extends the capabilities of the BDX.
It offers the opportunity to generate different plots of the discharge curve:
- Battery voltage [V]
- Discharge current [A]
- Discharge power [kW]
- Capacity discharged [Ah]
- Energy discharged [kWh]
Many functions are available, and very simple to use it is possible to generate test reports with plots and
comments automatically, to export the test data to external spreadsheets (compatible with Microsoft Excel, Open office CALC and others), to save a complete test to a single file and send it by email etc...
When two or more BDX units operate in parallel, it is possible to download all the data to TrendCOM, and to merge them into a single, complete test report. This feature gives the opportunity to achieve an unlimited discharge power, by connecting an unlimited number of BDX units in parallel.
During the operation, the external parts of the cabinet remain cold (max temperature rise is 10°C), for maximum safety for the user.
The BDX can be moved easily and safely on any floor, and can operate without problems in any industrial environment.
