BMW and Viessmann partner on smart energy storage solutions

German automobile producer BMW and heating systems manufacturer Viessmann Group have partnered to offer energy management solutions and associated consulting services.

The two companies have formed Digital Energy Solutions, which will offer energy management solutions that span multiple disciplines including electromobility, electric power, air conditioning and heating.

BMW brings to the partnership its expertise in electromobility, along with its charging infrastructure access service ChargeNow, according to a report in EE Times India.

ChargeNow allows BMW electric vehicle owners to access the nearest EV charging point, with real-time use status shown, if available.

Through Digital Energy Solutions, BMW and Viessmann Group also plan to establish a new business field that integrates high-voltage batteries into stationary smart energy storage systems.

Initially, the company’s services will be offered only to small-to-medium sized companies in Germany and Austria.

Energy storage system

The smart energy storage systems developed by BMW and Viessmann will use a combination of batteries from used electric vehicles and new batteries.

The energy storage system will be controlled by purpose-built software called ‘Smart Energy Backbone’, developed by the German car manufacturer.

The software is based on BMW’s existing in-house energy management used in the company’s global manufacturing network.

EE Times India adds that the decision to establish Digital Energy Solutions is due to a growing trend towards renewable energy and the demand for energy buffers and storage systems. Reducing carbon emissions in per vehicle is another factor motivating the launch of the company.

Other car manufacturers such as Japanese automobile manufacturer and fellow German carmaker Daimler AG have also endeavoured to enter the energy storage market, and have set up similar business independently.

The business model for energy storage systems such as the one developed by BMW and Viessmann is based on the premise that batteries from EVs which have reached their useful life, can be re-purposed and re-used for storage applications. EV batteries reportedly still have 80% capacity after having reached their lifecycle.
