Snowflake Data Warehouse for EV Charging Network and B2B Data Exchange

The Situation

A Volkswagen Group subsidiary building one of the largest electric vehicle charging networks in the US had established a strong analytics foundation on AWS and Tableau from day one. As their network grew, a new strategic opportunity emerged: the data being generated by charging hardware vendors was not just operationally valuable — it was potentially valuable to external organizations as well. Enabling private B2B data exchanges required a more modern, scalable data warehousing solution than their existing setup could support. Key challenges included:

• Growing data volumes from hardware vendors across a rapidly expanding national charging network
• No cloud data warehouse capable of supporting scalable data acquisition, storage, and distribution
• A need to enable B2B data sharing with external partners without manual effort or infrastructure overhead
• An existing Tableau environment that needed to perform better as data volumes increased
