Currently, the battery is the weak spot for the development and expansion of electromobility.
As a leading global analytics service provider, SGS has extensive expertise in battery testing. With our versatile testing options, we can cover the monitoring of the entire battery production process – from the basic materials to the complete battery system.
Technology chain up to the battery system:
