The BCS-8xx series Battery Cycling System is the newest line of advanced battery cyclers introduced by Bio-Logic. It is designed as a modular system that addresses the expanding needs of the industrial battery cycling market by providing superior specifications that bring a completely new quality to the battery market.

BCS-8xx series is the equipment of choice for your R&D department, quality control, certification, as well as academic research. The state-of-the-art BCS-8xx cyclers provide superior performance and specifications compared to the existing cyclers available on the market today, including 5 current ranges (every decade), 18 bit resolution in current and voltage, high precision coulometry, fast bandwidths (rise and fall times), smart sampling, interfacing with external equipment and temperature probes and many more. All standard.
All BCS-8xx modules come in a standard 19” format for rack mounting and are composed of 8 independent channels allowing a user to run simultaneous experiments with 18-bit  current and voltage resolution (allowing for high precision coulometry), adjustable bandwidth (for exceptional stability and fast rise/fall times) and smart sampling.

Every BCS-8xx module are available with an optional built-in FRA that allows for EIS studies over the frequency range from 10 kHz to 10 mHz on each channel in either galvano- or potentio- mode (selectable in the software).

This EIS measurement is as fast and precise as on our research grade equipment, so no compromise there. 5 current ranges are standard in each unit which allows to cover many orders of magnitude in current with a single unit. Furthermore BCS-815 channels can be put in parallel in order to reach +/-30, +/-60 or even +/-120 A.
Each BCS-8xx module has analog/digital inputs and outputs which can be used to control and communicate with an external device.

The BCS-815 and BCS-810 battery cyclers are equipped with dedicated K-type thermocouple inputs for each channel.
In case of BCS-815, cycling and Logic electronics are powered independently allowing for uninterrupted data acquisition even with small UPS units, as well as safe shut-down in case of a major power grid failure. Our software and firmware allows for easy resumption of operation.

Depending on the current required, three modules are available:

  • BCS-815 (up to +/-15 A; up to +/-120 A in parallel mode)
  • BCS-810 (up to +/- 1.5 A)
  • BCS-805 (up to +/-150 mA)

BCS-8xx modules are Plug and Play allowing for easy installation, module replacement and maintenance without affecting the other running modules. The various models can be mixed in a single cabinet.

Depending on the cabinet and the BCS-8xx models selected, a cabinet (BCSC-38U) can be configured to hold from one to up to sixteen BCS-8xx modules, corresponding to 128 channels .
All BCS-8xx series instruments are controlled by our BT-Lab – a powerful software suite based on our industry-leading EC-Lab software. In BT-Lab software, all of the main battery parameters are automatically processed and displayed on-line in real time. It is provided with the unit at no additional cost.
Each channel can be individually controlled from a different computer over the local network, while many units can be controlled and monitored from the same instance of the BT-lab software. Your operations can be very flexible and your managers will be able to monitor channel status without leaving their desk, or interrupting your technicians’ work on the lab workstation!
