Battery Cycling and Multiplexer

On this page Zimmer and Peacock discuss the battery testing/cycling workstations from Zahner. Please if you have any questions regarding Zahner's battery cyclers and multiplexers please feel free to contact Zimmer and Peacock.

Zahner introduce the Battery Cycling Multiplexer BC-Mux.

The battery cycling multiplexer BC-Mux connects the high power performances of DC battery test systems with the EIS capabilities of ZAHNER ZENNIUM Electrochemical Workstations. Incorporating the BC-Mux into high power battery DC test stands allows engineers and researchers to carry out electrochemical impedance spectroscopy (EIS) at any point of time during their cycling experiments. The BC-Mux functions as an automatic switcher connecting sequentially the single cells of a battery or fuel cell pack from the DC tester to a ZENNIUM series Electrochemical Workstation for EIS measurements. Up to 16 cells can be addressed for cell evaluation. Communication (i.e. MODBUS protocol) to the cycling test setup is established either via USB or TCP/IP network to a host computer, which controls all test procedures by software. Integration of the BC-Mux into DC test stands allows the user to access important information about the investigated battery and fuel cell systems such as state-of-health (SOH) and state-of-charge (SOC).
