When the battery is first charged, the battery cell expands. If a critical limit value is exceeded, there is a risk of structural damage or even rupture of the cell. In order to reliably detect this point and stop the charging process in good time, the battery is integrated into a specially developed test stand.

Laser sensors from Micro-Epsilon precisely measure the vertical expansion of the cell over several charging and discharging cycles. These compact sensors can also be accommodated in confined spaces and deliver high measurement accuracy.

Advantages:

• Compact laser sensors with high accuracy
• Reliable expansion monitoring
• Various interfaces for seamless integration
