Enables high-rate charge/discharge tests necessary for enhanced rapid charge/discharge performance.
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.
10 ms continuous measurement (at the fastest setting)
Supports single cell evaluation (C-rate can be set)
When an error is found, a built-in path switch immediately terminates the test.
Four thermostatic chambers (produced by Espec) can be operated synchronously
A T-type thermocouple (optional) can be used to measure temperature.
The system can be set up by connecting a LAN cable.
Enhanced protection functions
System Configuration
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.
Example of PFX2731S x 4 units and constant temperature chamber x 4 units connected via LAN cable
*Either LAN or RS485 is used for the connection to the temperature chamber.A separate USB converter is needed for connection to a PC when using the RS485.
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 Discharge
It is a general constant current discharge. Termination by capacity (Ah) is another option in addition to voltage and battery temperature.
CC-CV Charge
This charge method switches from constant current to constant voltage automatically. It supports CV time and It current detection.
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.
