Battery Discharger

The Battery Discharger 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 maxium 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 Battery Discharger shuts down automatically, while the measured parameters remain available to the user. The Battery Discharger is very simple to use and doesn't require particular training. The programming of the test requires less than 2 minutes and the operation is completely automatic.

High frequency IGBT regulator, featuring constant current discharge of the battery

  • Rugged construction for maximum reliability in heavy duty industrial applications
  • Compact and easily portable
  • Standard models for battery voltages up to 400 V
  • Single units with parallelable design, for unlimited total discharge current
  • Intelligent electronic protection system (includes soft start, battery polarity reversal and overtemperature)
  • Programmable digital board, microprocessor controlled
  • Can operate with batteries of any type
  • Digital display (battery voltage and current, time, capacity discharged, programmed values)
  • Integrated DataLogger, PC interface (RS-232 or USB)
  • Dedicated PC software TrendCOM for data acquisition and analysis, automatic generation of test reports, export capability to external spreadsheets (MS Excel, Openoffice Calc, etc...).
  • CE certified UL / CSA certified ISO9000 Quality control compliant

Key Features

  • Electronic polarity reversal and anti-arcing protection (without fuses). An active circuit prevents any arcing between the connectors when the battery is being connected. If a battery is connected with reverse polarity, the Battery Discharger doesn't start and no current flows.
  • Auto-Test at power-on. When the Battery Discharger 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 Battery Discharger remains in a safe, stand-by mode.
  • Integrated DataLogger. While the discharge is in progress, it's not necessary to leave a PC always connected to the Battery Discharger, because the integrated DataLogger has enough memory to save the entire discharge curve. At the end of the test, it's possible to download the data from the Battery Discharger to the PC in seconds. The standard connection interfaces are serial (RS-232) and USB. Wireless interfaces are available on request.
  • Extended Analysis capability, with the TrendCOM PC software TrendCOM is a powerful, dedicated software that extends the capabilities of the Battery Discharger. 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's possible to generate test reports with plots and comments automatically, to export the test data to external spreadsheets (compatible with Microsoft Excel, Openoffice CALC and others), to save a complete test to a single file and send it by email etc...
  • Unlimited parallel operation, managed by software. When two or more Battery Discharger units operate in parallel, it's 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 Battery Discharger units in parallel.
  • Temperature protection of all the power components and resistor bank. In case of internal overtemperature (e.g.: blocked fans, air passages obstructed) the discharger is set automatically in stand-by mode.
  • Double cabinet, for maximum thermal insulation. During the operation, the external parts of the cabinet remain cold (max temperature rise is 10°C), for maximum safety for the user.
  • Heavy duty metal wheels, with ball bearings, covered with rubber. The Battery Discharger can be moved easily and safely on any floor, and can operate without problems in any industrial environment.
