Image: BoschBosch and Mitsubishi Corporation aim to establish themselves in the market for ‘BaaS enablement solutions’ and consulting services through their joint venture founded in 2025. Specifically, the partnership seeks to provide the infrastructure required to support their customers’ Battery-as-a-Service business models. Target groups include leasing companies, battery swap operators, fleet operators, battery energy storage system providers, and insurance companies.The joint venture has now secured its first customer: Shanghai Lingzhou Technology. The battery swap station operated by this client in Chizhou is the first to use technology from Bosch MC Battery Service Innovations. “This provides a tailored charging experience and enhanced asset monitoring and protection. The facility currently services more than 100 trucks daily,” Bosch stated.According to the partners, the charging process uses artificial intelligence and is complemented by additional services. This approach allows operators to monitor vehicles and batteries more effectively and helps maintain their value. One trend is already clear: electric trucks are rapidly gaining ground in China. “Nearly 30 per cent of all heavy-duty trucks sold in 2025 were already so-called New Energy Vehicles (NEV). For 2030, Bosch even expects more than every second new truck will be purely electric. China is considered a pioneer in the transformation of heavy-duty transport,” the German automotive supplier stated.The joint venture aims to further accelerate this growth by addressing a key challenge for electric fleet operators: declining battery capacity over time makes it difficult to predict the residual value of both the vehicle and the battery. To tackle this issue, Bosch is providing its ‘Battery in the Cloud’ solution as the technical basis for the joint venture’s services. The software determines the precise State of Health (SoH) of the traction battery, forecasts its future condition and helps optimise the charging process.“With this service, Bosch and Mitsubishi Corporation can create real added value for fleets,” said Thomas Pauer, President of the Bosch Power Solutions division. “Although the state of health can decline due to aging and many charging cycles, our solution allows fleet operators to keep an eye on the battery condition of their vehicles – a decisive criterion for the everyday suitability and total cost of ownership of a fleet.”“Our service hits a local nerve: We support battery-electric vehicles in the fleet business,” said Qian Yang, general manager of the joint venture’s local subsidiary in China. “This holistic approach accelerates the electrification of fleets and optimises the entire battery lifecycle. The combined expertise of Mitsubishi and Bosch is a perfect match for our customers.”Additionally, the collected charging data can be used to improve aftermarket services such as connected insurance, vehicle and battery maintenance, and other offerings. Bosch and Mitsubishi have collaborated on this topic since 2019. An initial trial of the services ‘has already been successful,’ the companies report, though no further details were provided. Diagram of Bosch’s ‘Battery in the Cloud’ solutionGrafik-BoschBosch and Mitsubishi had already signed a memorandum of understanding with Blue Park in spring 2022 outlining the project in broad terms. At the time, the partners announced plans to establish a Battery-as-a-Service business model based on a battery-swapping platform. Bosch committed to contributing its Battery-in-the-Cloud technology, while Mitsubishi was to provide its commercialisation capabilities, according to the announcement. Under the original plans, Blue Park was to supply the swapping platform, with the project initially focusing on the Chinese market.That was over four years ago. Since then, the project remained quiet until Bosch and Mitsubishi introduced a joint venture named Bosch MC Battery Service Innovations GmbH in July 2025, which is set to develop the BaaS business for both groups. The establishment of the joint venture was also approved by the EU Commission last year under the European Union’s Merger Regulation as reported here.Bosch and Mitsubishi each hold 50 per cent of the shares in the joint venture and exercise joint control. Furthermore, the service is expected to be available from mid-2025 in the European Union, Japan, China, the United States, and India, according to the EU Commission. The EU document no longer prioritised China, nor was the previously mentioned partner Blue Park referenced.What is clear: Bosch and Mitsubishi continue to emphasise the potential of BaaS offerings, as they eliminate upfront investment costs, downtime during charging, and battery uncertainty. These are all factors that hinder the electrification of commercial fleets, as Mitsubishi noted when announcing the plans.bosch-presse.de
