Features
Energy Storage Essential to New Energy Application.
-Fully support Charge and Discharge Measurement from Basic Test to Simulation Test-
PFX2512/2532 Series is a high performance Charge/Discharge system controller that takes measurements in combination with our DC power supply and electronic load in order to evaluate test sample (electric storage elements such as secondary batteries) characteristics. It is also capable to perform evaluation test with high-performance, large capacity and wide range of rating with the combination of DC power supply and electronic load. Execution of the test is conducted by the exclusive application software. The test corresponds to long time continuous test and synchronization test with temperature chambers with the multiplexed protection performance. In addition, easy data editing is also capable with fulfilling graphic performance.
Complicated Systems Integrated into One
PFX2512/2532 Series has integrated systems into one unit where battery evaluation is required. In addition, the series has high degrees of flexibility corresponding to wide range of rating since it is possible to combine our conventional DC power supply (for charging) and our electronic load (for discharging) tailored to needs. Introduction cost is able to be reduced by selecting equipment which meets charge/discharge test condition required.
Corresponding to Specification Test Pattern by Realizing Seamless Charge/Discharge
A certain time was required for transferring power supply and electronic load in the past. Seamless charge/discharge transfer has been realized at PFX2512/2532 by the simultaneous control of power supply and electronic load. For this reason, correspondence to characteristic test of recapturing complex applications such as application where charge/discharge repeating without taking breath is performed for electric motorcycle and electric assisted bicycle as well as electric vehicle and hybrid vehicle, and application for UPS for peak shift and to specification test pattern where continuous charge/discharge is performed such as IEC62660 became possible.
Easy Configuration
It is possible to configure the system by yourself. The DC power supply and electronic load that are applied configuration with PFX2512/2532, can be used for the system. This allows you to have a test system at low cost.
Control of the Constant Current (CC) and Constant Voltage (CV)
The adoption of the digital CC/CV control method minimizes the disparities in the constant current(CC)/ constant voltage(CV) setting accuracy and drift characteristics due to the differences in the system component devices(DC power supplies and electronic loads). This ensures highly accurate tests. There is absolutely no need to make adjustments after system configuration.

Highly accurate measurement
Highly accurate measurement circuits are built in. Battery voltage and charge/discharge current are detected with high accuracy. (Voltage measurement: 100 μV resolution, current measurement: 100 μA resolution, elapsed time measurement: monthly error of 30 s or less (10 ppm or less)) True electric energy and integrated capacity can be measured even for pulse currents that are difficult to be captured.
