German industrial giant Siemens has signed up as the latest major backer of Northvolt, the fast-emerging battery technology start-up that has already forged links with Vestas in the wind power sector.

Siemens will supply its digital enterprise technology as part of a €10m ($11.7m) investment in a partnership with Northvolt that will include buying batteries from the company, which is planning to build Europe’s largest battery factory in its Swedish homeland.
