Batteries design kit
There is a large variety of battery cells form factor, chemistry, measurement, safety requirements and balancing are specific to the application.
The battery design kit allows rapid prototyping of a battery cell monitoring unit (CMU) intended for integration inside or outside battery cells. The hardware design includes a comprehensive set of measurement and sensors implemented at lowest integration cost, and it can be easily subset with the supporting software development kit (SDK).
The DK is supplied with the SLM-Studio PC application software which can perform complex, prolonged, automated measurements and data logging sessions.
Applications include smart batteries, distributed battery management systems, in-line manufacturing automated battery testing and support to new materials chemistry research and characterization.
The smart battery DK was developed in collaboration with the Austrian Institute of Technology (AIT).
