General Description
This chapter describes the product, the
devices that can be connected to the product,
and the procedure from charge / discharge
test preparation to test execution.

14 PFX2512
Product Overview
The PFX2512 is a dedicated charge / discharge system controller used to measure the charge /
discharge voltage and current of batteries and the like with high accuracy in combination with
Kikusui’s DC power supplies and electronic loads to evaluate the characteristics of DUTs (power
storage devices such as rechargeable batteries). Depending on the DC power supply and electronic
load combination, large capacity, and wide rating range evaluation tests can be performed.
Features
Charge / discharge control system
●Wide range of ratings
Wide range of ratings can be supported by selecting the appropriate combination of Kikusui’s
DC power supplies and electronic loads. Implementation cost can be suppressed by selecting
the appropriate devices for your charge / discharge test conditions.
●Digital constant current (CC) / constant voltage (CV) control method
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
The PFX2512 has a built-in path switch (load switch). The path switch is equipped with a high-
speed shutoff function that quickly detaches DC power supplies and electronic loads when an
error is detected.
It also detects electric potential difference that exceeds specified values in DUT cables and
voltage sensing wires, wiring errors, poor DUT (battery) connection, and so on to prevent
damage to the connected devices and DUTs (batteries).
For the system requirements, see the BPChecker3000 application software’s setup guide.

General Description
●Vibration sensor
In a disaster or the like, the PFX2512 detects large shaking and shock during charge / discharge
test and turns off the output. This prevents damage to the connected devices and DUTs
(batteries).
●10 000-step pattern charge / discharge feature
You can set up to 10 000-step CC or CP (with V or I limits) steps.
High-speed charge / discharge switching control enables you to perform complicated charge /
discharge tests with step times as short as 100 ms. The PFX2512 can be used to create a wide
variety of test and simulation patterns for standard tests.
●High-speed charge / discharge switching
Traditionally, it has taken time to switch between controlling DC power supplies and controlling
electronic loads. This product can be used to control DC power supplies and electronic loads at
the same time, which enables seamless charge / discharge switching.
●High-speed sampling as fast as 1 sample / ms
Voltage and current can be measured at an interval as short as 1 ms with the specified voltage
or current step as the trigger. You can acquire highly accurate voltage waveforms that are
synchronized with the step current. This is an optimal feature for analyzing test impedance and
evaluating service life of DUTs.
●Expandable cell monitor measurement feature
By installing a Volt/Thermometer Unit OP02-PFX (sold separately), you can expand the number
of measurement points by 4 voltage and 4 temperature measurement points. You can expand
the number of measurement points by a maximum of 12 voltage and 12 temperature
measurement points.
If you further need to expand the number of voltage measurement points, you can increase the
number to 72 by installing OP03-PFX Voltmeter Units (sold separately) in a 8 Slot Unit SL01-PFX
and installing a Volt/Thermometer Unit OP02-PFX (sold separately) in the PFX2512 main unit.
●Cell CV function
A cell CV function is available in addition to the cell unbalance detection function. During
charging, the PFX2512 instantly detects the highest cell voltage and controls the charging
operation so that the specified cell CV value is reached. During discharging, the PFX2512 does
the same for the lowest cell voltage.
Safe charge/discharge is possible even on battery modules with unbalanced cells.
●Support for EV standards
The system supports tests for EV-related standards such as the IEC standards. It is easy to use
and works well with Microsoft Office software. It also has features for displaying and exporting
high-speed sample data.

System Configuration
The following figure shows a basic configuration example of a charge / discharge system that uses
the PFX2512. The system consists of a PFX2512, Kikusui’s DC power supplies and electronic loads,
and peripheral subsystems.
The PFX2512 functional block is mainly made up of a DUT voltage / current / temperature
measurement section, a digital constant current / constant voltage control section, a power supply
/ electronic load I / F section, a host communication control section, and a load switch.
The PFX2512 has an interface that directly connects to Kikusui’s power supplies and electronic
loads. The system is designed to allow full-scale charge / discharge testing with easy initial
configuration without extra equipment or external circuits.
The connection status of DC power supplies, electronic loads, and DUT (battery) is constantly
monitored. If a problem is detected in any of the devices, the charge / discharge test is safely
aborted.
The PFX2512 is controlled from a PC through the LAN interface.
Application software BPChecker3000 is used to configure and control charge / discharge test
conditions. For details on the application software, see the corresponding help file.

General Description
The 1 channel of the charge and discharge system consists of one unit of each PFX2512, DC power
supply, and Electronic load.
The figure shown above is an example of system configuration for 2 channels of the charge and
discharge system. This system consists of 2 sets of each for the PFX2512, PWR1201ML (Regulated
DC power supply), the PLZ1205W (Electronic load) , and 1 set of each for the PC installed into the
rack unit connecting with the temperature chamber.
If you configure a system with the Charge / Discharge System Controller PFX2512, you can connect
charge / discharge units with 72 voltage measurement points and 8 temperature measurement
points or 12 voltage measurement points and 12 temperature measurement points to up to 7
channels (using options1).
Synchronized testing with a temperature chamber is also possible. An ESPEC temperature chamber
is connected to the PC through a dedicated USB-RS485 converter2. To perform a synchronized test
with a temperature chamber, you need a VISA 3library.
1 The Volt / Thermometer Unit OP02-PFX, which is installed in the PFX2512, and the Voltmeter Unit
OP03-PFX, which is installed in the optional 8Slot Unit are available.
