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.

Charge/Discharge System Controller

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.

System Conceptual Diagram

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.

Protection Functions for Safety Operation

Equipped with protection functions provided by hardware and software against phenomena such as overcharge and overdischarge. The route switch (load switch) is built in the PFX2500 series and it equips with a function to ensure connection between the DUT (batteries) and the DC power supply/electronic load as well as a high-speed interruption function that promptly disconnects the DC power supply/electronic load in case any abnormal state is detected. In addition, the vibration sensor detects major vibration and shock in case of a disaster or accident during charge and discharge test, then shuts off the output, and it prevents a damage to the connected equipment and the DUT (batteries).

Up to 10000 Steps for Pattern Charge/Discharge

It is capable to set the CC/CP (with V, I limit) step values up to 10000. Complicated charge/discharge test with minimum 100 ms step of time window since high speed charge/discharge transfer control becomes functional. This widely corresponds to the generation of test patterns or simulation patterns for various specification tests.

Capable of Expanding Measurement Function

Measurement points, 4 points for voltage and 4 points for temperature, are able to be added by installing optional voltage/temperature Unit, OP02-PFX. Since there are 3 slots for optional board, measurement point addition is capable up to 12 points for voltage and 12 points for temperature as
maximum.
By installing an Voltmeter Unit OP03-PFX in an option slot on the SL01-PFX*1, you can increase the number of voltmeter measurement points. If OP03-PFX units are installed in all option slots of the SL01-PFX*1, voltage measurement points can be expanded to 64 points.

*1 OP02-PFX cannot be installed. When using the option “SD01-PFX”, one of the internal expansion slot of PFX2353/2512 will
be used.

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.

Realized Maximum 1 ms High Speed Data Sampling

Minimum 1 ms (maximum 6000 points for every profile) voltage/current measurements are capable by assigned voltage and current steps as trigger. This is most suited to impedance analysis of test and evaluation of life determination since high-precision voltage waveform synchronized to step current can be acquired.

  • Sampling rate: selected from 1 ms/10 ms/100 ms
  • Cell voltage meter: fixed at 100 ms of sampling rate (at OP02-PFX installed)
  • 4 types of measurement start triggering (just after charge- discharge start/just before charge-discharge completion)
  • 6000 sampling storage: 6 s @1 ms/60 s @10 ms/ 600 s @100 ms

Fastest 1 ms high speed data sampling

More Accurate Single Cell Evaluation with 6V Range

PFX2512/2532 equips Voltage Range transfer capability between 6 V and 60 V. A 6 V range was newly installed in PFX2512/2532 in order to perform evaluation more accurately even for a single cell. 6 V range accuracy = ±(0.05 % of reading + 0.04 % of rating), 60 V range accuracy = ±(0.05 % of reading + 0.02 % of rating). In addition to the stacked cell assembly, more accurate characteristic test is capable with single cell.

Applied to CAN interface

PFX2512/2532 (BPChecker3000) is able to communicate with exclusive application where communication log, analysis, emulation functions, etc, are added. Herewith, it becomes possible corresponding to various demands such as synchronization between charge/discharge control and log segment, charge/discharge control from exclusive application.

Note on selecting power supply for charge (route loss)

Application of the charge current causes a voltage drop in the DUT cable, connecting cables, the
current pass route of the PFX2500 series, etc. The power loss at charging caused by this voltage
drop is the route loss. The maximum power that can be used for charging is the value from which
the route loss is subtracted.
[Maximum charging power = maximum rated power of DC power supply – path losses].

Note on selecting electronic load for discharge (minimum operating voltage for discharge)

The electronic load has minimum operating voltage (1.5 V in PLZ1004W), and it does not operate
at the voltage below the specified level. The result of an addition of this level and the route loss
(voltage drop) is the minimum operating voltage for discharge.
[Minimum operating voltage for discharge = Minimum operating voltage of electronic load + Voltage
drop caused by route loss]
