As the battery market continues to grow rapidly, batteries also need to keep improving. Batteries must be lighter and smaller, while at the same time offering greater capacity, a longer lifetime and and lower prices.
The electrical characterization of battery cells forms the basis for system design, modeling, cell diagnosis and cell monitoring. This allows dangers to be reduced during operation by meeting voltage, current, and temperature limits
- a more accurate estimation of capacity and operation time, thus also increasing the range of, for example, electric vehicles
- aged cells to be replaced faster to extend the life of the battery pack and reduce costs
The electrical characterization of test cells includes standard tests such as capacity measurement, open-circuit voltage measurement, differential voltage analysis, pulse testing, dynamic charge acceptance tests, electrochemical impedance spectroscopy, and other frequency-based excitations.
