Battery intelligence from Bosch and Mitsubishi Corporation

Bosch MC Battery Service Innovations GmbH, BMB for short, is a 50:50 joint venture of Robert Bosch GmbH and Mitsubishi Corporation. It is headquartered in Ludwigsburg, Germany. The European Commission cleared the joint venture in August 2025. The two partners have worked together on battery services since 2019.

BMB builds software and services for the new energy industry: for everyone who charges, swaps, leases, stores, finances or insures batteries.

Bosch brings the battery intelligence, Mitsubishi the route to market

Bosch brings its experience in electrified power solutions and battery intelligence. Its Battery in the Cloud software calculates the State of Health of a battery, forecasts how it will age and helps optimise how it is charged.

Mitsubishi Corporation brings its global commercial network: market access, and a link into the service and aftermarket chain that keeps batteries running for years.

BMB reads the real capacity of a battery, how to charge it and what it is worth

From a battery’s own operating data, BMB reads its real capacity and State of Health, how it should be charged and what it is worth. That becomes an independent SoH figure and a charging profile that protects the pack. It also delivers early warnings for cells that drift, and a record that settles who pays for each battery swap.

Customers include operators of charging and battery swapping infrastructure, logistics fleets, leasing companies, grid scale storage operators, investors and insurers.

Already running on real batteries, from Chizhou to Germany

Battery swapping for electric trucks, China

In Chizhou, electric trucks swap or recharge their batteries within minutes at an energy service hub run by BMB customer Shanghai Lingzhou Technology. BMB turns the data from every swap and every battery into intelligence that helps the operator run the hub.

Battery management for an energy company, Germany

For a large German energy company, BMB manages the batteries. Every battery is monitored from its own operating data. The company knows the real State of Health and can act before a problem grows.

Battery storage and electric trucks, Germany

With a German energy provider, BMB runs a proof of concept that combines battery storage and electric trucks. It optimises the fleet and earns extra revenue from the batteries when their capacity is not needed, for example at weekends.

In 2026 the technology is proven. BMB is now connecting grid scale storage operators, leasing and remarketing companies, fleet charging and energy service providers and logistics companies to its platform.

Based in Ludwigsburg and Shanghai, working with customers in Europe and APAC

BMB is headquartered in Ludwigsburg, Germany, and opened an office in Shanghai in April 2026. From Ludwigsburg, BMB serves customers across Europe.
