Battery Cell Management Unit (CMU)

Designed for battery engineers and researchers, the CMU allows performing multiple measurements of batteries, supercapacitors or fuel cells while in operation.
The CMU is based on the SENSIPLUS microchip which includes an Electrochemical Impedance Spectrometer with Lock-In Amplifier, measuring 1^st, 2^nd and 3^rd harmonics, a Potentiostat/Galvanostat along with on-chip sensors for Temperature, Relative Humidity and Gassing. The Positive and Negative tab electrodes included in the CMU kit enable a 4 contacts measurement of the cell internal impedance and temperature. Coulomb counting can be performed without shunt resistor and be adjusted for ageing.
An off-chip interface supports external sensors such: strain, pressure, electrolyte leakage and moisture. 
The CMU is chemistry independent; it can be used with Li-ION and Li-Fe-PO₄ battery packs, similarly it can be applied to 3b generation of LNMO cells, Supercapacitors and Fuel Cell combinations.
