Grid buffer for external power supply in vehicle final assembly
In modern automotive manufacturing, a continuous power supply is essential for ensuring process reliability and product quality. This is exactly where our external power supply solution comes into play, developed specifically for a major automotive manufacturer. The intelligent battery system with integrated inverter is built directly into a skid platform used in the vehicle final assembly process.
The challenge: during certain conveyor sections, the platform is temporarily disconnected from the power rail. At the same time, vehicle bodies still require power for processes such as software updates, system testing and ECU flashing. Our solution bridges this gap and ensures a stable, uninterrupted power supply – compactly integrated and precisely adapted to the limited installation space available.
This allows vehicle systems to be fully tested even when disconnected from the regular power supply. At the same time, operating and diagnostic data remain continuously available.
The solution was initially deployed successfully at a production site in Germany before being further optimised for use in additional plants. At its core is an ultra-flat lithium-ion battery system with integrated battery management. A carefully designed control architecture ensures high reliability and ease of maintenance.
A continuous power supply and uninterrupted access to diagnostic data are essential for reliable production processes. That is exactly what our grid buffer provides – even beyond the power rail.
