MATERIALS AND CELLS DEVELOPMENT

Techniques

• Electrochemical impedance spectroscopy (EIS)• Cyclic Voltammetry• Galvanostatic measurements...• Electron microscopy (SEM-TEM),Energy-dispersive X-ray

spectroscopy (EDX), X-ray diffraction, Raman spectroscopy…• Conductivity measurements either in 2- or 4- point

configurations

✓ Cell type

• Flow cells• Coin-cell testing (half-cell, symmetric,..)• 3-electrode cell • Modules or battery packs up to 15 A

✓ Testing in extreme conditions of temperature (-20 to 180°C ) and humidity (30-90RH), so covering for instance EVoperating requirements

BATTERY PACKS

BATTERY SIMULATION AND CONTROLS

BATTERY SIMULATIONWe can also simulate battery behavior given any current

profile using the full- and reduced-order models.

ACTUAL BATTERY

Only voltage, current and

temperature measurements

BATTERY STATE ESTIMATION

Model based estimators use battery models (seen in the previous slide) in order to estimate cell variables that are not directly measurable or difficult to obtain in real-time.

• Physics-based models based on electrochemical transfer functions allow cell internal variable estimation, which can help minimizing degradation!

SOC?SOH?…?

BATTERY CONTROLSWe can use cell internal variable estimates to optimally control the battery. Advanced control strategies such as

model predictive control (MPC) can be used.

For example, what is the best way to charge my battery if we are interested in

minimizing degradation?
