Ultra-precision battery cyclers

BCS-800 battery cycler series.

Powerful, flexible, ultra-precise battery cycler with EIS capability

BCS-800 series is a modular battery cycling system designed to meet the needs of every level of the battery value chain, from R&D to pilot production, from production testing to quality control. Made up of three core products (BCS-805, 810 and 815), these advanced battery cyclers offer 8 independent channels with a maximum current of ±150 mA, ±1.5 A and ±15A, respectively per channel.

The BCS battery cycler series: Modularity, flexibility and ultra-precision.

The high-performance BSC-800 battery cycler series boasts an impressive range of specifications, as standard, that surpasses all other battery cyclers currently available on the market. This range of ultra-precise cyclers features five current ranges, 18 bit current and voltage resolution, high-precision coulometry, fast bandwidths (rise and fall times), smart sampling, interfacing with external equipment and temperature probes amongst many other high-end functions.

The result is a powerful, modular system suitable for any organization specializing in battery testing and research, from industry to academia, quality control to certification.

 

High-performance battery cyclers that excel at every level of the value chain.

The BCS-800 battery cycling series is available in three core modules, all of which have been built around the same high-end technological framework, but which each offers specific current ranges targeted at key industrial/academic applications.

The BCS-805 is the smallest battery cycler with a maximum current of ±150 mA per channel, making it highly suited for small batteries such as coin cells. The BCS-810, with a maximum current of ±1.5 A per channel, is a medium-size battery cycler, making it ideally positioned for R&D laboratories and pilot lines. Finally, the BCS-815, the workhorse of the battery cycler family, with its maximum current of ±15 A per channel is ideally suited for high-power tests, and offers the possibility to connect channels in parallel, in order to reach ±30, ±60 or even ±120 A.

 

Precision, accuracy & modularity: three reasons to choose the BCS-800 battery cycler series.

With an 18-bit current and voltage resolution, the BCS-800 battery cycler series has been developed to generate high-precision high-accuracy measurements. Five current ranges yield excellent resolution down to 0.2/2/20 nA. Moreover, a large voltage range of 0 – 9*/10 V (815*) with a 40 µV resolution offers a wide potential window for demanding applications with an outstanding resolution. And the calibration offered by BCS-CAL kit will ensure that your instrument continues to consistently perform throughout its lifespan.

An optional built-in FRA (Frequency Response Analyzer) is available for every BCS-800 module enabling Electrochemical Impedance Spectroscopy (EIS) experiments over the frequency range of 10 kHz to 10 mHz on each channel in either galvano or potentio mode. EIS measurements are as fast and precise as those obtained with our research-grade equipment – no compromise on quality has been made. Want to know more about Electrochemical Impedance Spectroscopy and why using it? Click here.

High accuracy and precision for both control and measurement allow users to perform challenging experiments such as dQ/dV or HPC (high precision coulometry). Coupled with EIS, the evolution of your batteries’ parameters can be precisely determined (SOC, SOH, internal resistance Ri). The instrument offers a fast data acquisition with a 2 ms sampling rate and time base. Learn more about data of interest to work more efficiently.

There is no need to stop your experiment if you want to add a module to your system! The plug and play design of all our BCS-800 battery cycler modules facilitates the installation, replacement and maintenance of modules without disrupting any units already in operation. Thanks to their modularity and compatibility, different BCS-800 modules can be combined in a single cabinet, in one of 4 units (6U, 12U, 24U and 38U), allowing users to builhttps://www.biologic.net/topics/hpc-the-importance-of-ultra-precision-cyclers/d a custom-made battery cycling system that meets their exact requirements that can be easily upgraded for the future, if necessary.

 

Centralized control for external devices.

Your BioLogic battery cycler also includes analog input/output and trigger input/output that can be used to control and communicate with an external device, such as a thermostatic chamber. Every BCS-810 and 815 modules are also equipped with a dedicated K-type thermocouple input on each channel to allow temperature measurement on each cell.

BT-Lab®: Powerful, flexible, bespoke battery testing software.

Our powerful control software BT-Lab® is provided with all BCS-Series battery cyclers at no additional cost. Instruments are connected to BT-Lab® software on your computer via an Ethernet connection enabling multi-user or even multi-site network connectivity. Furthermore, this software is not limited to merely controlling the battery cycler but can manage every aspect of your experiment from beginning to end, including control, advanced analysis and data export (amongst other valuable functions).

For example, it ensures that all of the main battery parameters (capacity, energy, power, Rapp etc) are automatically processed and displayed on-line in real time. More information can be found on the BT-Lab® software page.

From cells under development to the quality control testing of commercial cells, the strength-in-depth of BT-Lab® makes it perfect for a wide range of applications including (but not limited to):

  • Battery and supercapacitor cycling
  • Suitable for HPC (High Precision Coulometry) (RMSE<10 ppm)
  • Incremental capacity dQ/dV measurements
  • EIS (Electrochemical Impedance Spectroscopy)
  • Life Cycle
  • PITT/GITT
  • Capacity slippage
  • User profile
  • Aging
  • Second life
