Features

The PFX2731S is a 6 V-20 A 6-channel battery tester that supports high-rate charge/discharge tests. It is operated with the application software BPChecker4000, which is exclusive to the PFX2731S. As one PC can operate up to 4 units (24 channels), one can construct a multi-channel charge/discharge system according to the required number of channels. In order to safely conduct long-term continuous testing, it also has 2-system independent protection functions for hardware and software, as well as various protection functions such as a connection confirmation function that detects incorrect wiring and integrated capacity protection.

System Configuration

Example of PFX2731S x 1 unit connected with LAN cable

Example of PFX2731S x 1 unit connected with LAN cable

The PFX2731S combines a control unit, a measurement unit, and a 6-channel 6 V-20 A charge/discharge unit into a single housing, allowing the creation of a compact charge/discharge system with up to 24 channels. Continuous data recording of 10 ms is possible for all channels due to the complete isolation and independent measurement functions of each channel.

The Charge-Discharge mode for the diverse applications

CC Charge

It is only for constant current charging. It supports -dV detection, and -dT/dt detection by battery temperature.

CC Charge

CC Discharge

It is a general constant current discharge. Termination by capacity (Ah) is another option in addition to voltage and battery temperature.

CC Discharge

CC-CV Charge

This charge method switches from constant current to constant voltage automatically. It supports CV time and It current detection.

CC-CV Charge

CC-CV Discharge

This discharge method switches from constant current to constant voltage automatically. It supports CV time and It current detection.
Since it is capable of a deeper discharge than the CC discharge profile, it can be used for high-precision discharge capacity measurement.

CC-CV Discharge

CP Charge

It is only for constant power charging. The charging current may be limited by the limit current if the voltage is low.
Termination by capacity (Ah) is another option in addition to voltage and battery temperature.

CP Charge

CP Discharge

It is only for constant power recharging. The limit current can be used to limit the discharge current if the voltage drops and the discharge current increases.
Termination by capacity (Ah) is another option in addition to voltage and battery temperature.

CP Discharge

CP-CV Charge

This charge method switches from constant power to constant voltage automatically. It supports CV time and It current detection.

CP-CV Charge

CP-CV Discharge

This discharge method switches from constant power to constant voltage automatically. It supports CV time and It current detection.
Since it is capable of a deeper discharge than the CP discharge profile, it can be used for high-precision discharge capacity measurement.

CP-CV Discharge

Pattern Charge/Discharge (CC(+CV), CP(+CV))

A pattern is a series of steps. A maximum of 100,000 steps of CC or CP charge/discharge can be switched at high speed.
More advanced pattern control is supported because the CV voltage can be adjusted for each step.
Even if there are many steps, like in a standard test’s pattern charge/discharge and simulation pattern, Excel can be used to input the data.

Pattern Charge/Discharge (CC(+CV), CP(+CV))

100,000-step pattern charge/discharge function

The CC/CP step value can be set up to 100,000 steps. The time width can be set from 100 ms to 999.9 s per step. Furthermore, because the CV voltage can be set for each step, it is possible to handle complex charge/discharge tests with flexibility, including test patterns for a variety of standard tests and simulation patterns.

The C-rate setting function makes changing complex test conditions simple

To accommodate the diversifying requirements of charge/discharge tests, the C-rate setting function has been implemented. The charge/ discharge current value of the profile can be set with the C-rate value based on the nominal capacity input value. As a result, the test conditions can be applied to all profiles by simply changing the nominal capacity input value when testing different battery types with the same C-rate conditions and test pattern.

Test Condition Editor

Since the C-rate conversion is performed based on the nominal capacitance value, all test conditions can be changed simply by changing the nominal capacitance value.

Since the C-rate conversion is performed based on the nominal capacitance value

High-speed Data Sampling

The measurement of voltage and current is performed using a 24bit A/D converter. Continuous data collection of 10ms is possible for all channels. (The data recording time can be selected between 10 ms, 100 ms, and 1 s.) Setting the delta voltage and delta current also makes it possible to collect data even when the voltage or current exceeds the set value.

*Specifying a short time setting increases the amount of recorded data. The amount of data will be in the thousands to tens of thousands if the test time is long (several hours or longer). Be sure to set it carefully.

Enables high-precision measurement

Battery voltage and charge/discharge current are accurately detected by a built-in high-precision measurement circuit. (Voltage measurement: 100 μV resolution, current measurement: 100 μA resolution) (Current measurement: 100 μA resolution at 20A range, 10μA resolution at 2A range)

Enhanced Protection Functions

Protection functions like overcharge and overdischarge are built into the hardware and software. Additionally, the main unit has a built in path switch and a high-speed shutdown function that instantly terminates the test when an abnormality is detected.

Resuming a test from any point

It is possible to resume the test from any point if it is interrupted due to a power outage, an alarm going off, or user action.

Resuming a test from any point

Fully Independent Operation for All Channels

Since each channel is fully independent, it can be controlled using various timings and test conditions.

Conditions for Various Charge/Discharge Cutoffs ※P6 充放電終止条件リスト参照

In addition to voltage, time and temperature, It current value and SOC can also be used to set the charge termination condition and discharge termination condition.

Easy Firmware Update

Downloading the firmware updater from our website will allow the PFX2731S’s firmware to be updated to the most recent version.

Application Software

SD035-PFX BPChecker4000

The BPChecker4000 allows the conditions for battery charge/discharge characteristic tests to be set, tests to be carried out, and the test results to be stored. BPChecker4000 consists of two programs, the Test Condition Editor and the Test Executive, which create and run tests respectively.

Test Condition Editor

All test conditions for charging and discharging are created and edited using this program. After creating a profile, a project is created by setting the sequence, general settings, etc. The test is run for each project by BPChecker4000.

Software conceptual diagram

● The battery temperature’s rest end conditions (Rest Temp) can be set
The rest time can be set to a specified time (fixed time) after charging ends, or a rest end condition based on the battery temperature can be set.
● Equipped with pause function
The pause function is one of the profile type options.
The test can be paused by using this feature.

Test Executive

The Test Condition Editor is used to create projects (test conditions), which are then assigned to each channel of the PFX2731S and put through charge/discharge tests by the program called Test Executive.
