More and more electric cars are finding their way onto the road. Bosch estimates that they will account for around 70 percent of all newly registered passenger cars in Europe by 2030. This is increasing demand for batteries and for the recycling of the raw materials they contain, such as lithium, cobalt, and nickel. Bosch has developed special machinery, equipment, and software for this purpose.

The subsidiary Bosch Rexroth is supplying Battery Lifecycle Company, a joint venture between REMONDIS subsidiary TSR Recycling and Rhenus Automotive, with Europe’s first fully automated system for discharging and disassembling battery modules. “Electromobility can only establish itself in the long term if sufficient raw materials are available for battery production. Recycling plays a key role here, and helps place our output on a sustainable footing: we reuse what we use, and we recover raw materials,” says Dr. Stefan Hartung, chairman of the Bosch board of management.
Experts predict that by 2030, Europe will require recycling capacity for up to 420,000 metric tons of battery material each year (Source: Fraunhofer ISI, 2023). “If we want to build a European circular economy, we need to integrate recycling firmly into the product life cycle and create the necessary infrastructure to do so. Bosch is contributing its technical expertise to this,” Hartung says.
It takes just a few minutes to deep-discharge a module. The system recognizes different battery designs, minimizing risks such as short circuits and fires.
Growing numbers of electric cars combined with limited resources and increasing legal requirements for recycling – the challenges are increasing. “What we do today sets the course for tomorrow. The batteries currently being installed in vehicles will have reached the end of their life in 10 to 15 years. We must use this window of opportunity to build the necessary recycling capacity,” says Steffen Haack, CEO of Bosch Rexroth.
According to the Fraunhofer Institute for Systems and Innovation Research, the technical systems required for recycling will require investment of more than 6 billion euros by 2040 in Europe alone (Source: Fraunhofer, 2021). Recycling will be worthwhile: optimum recycling can recover up to 95 percent of a battery’s chemical elements and recycle them into the battery production process. The automated discharging system developed by Bosch not only simplifies recycling, but also increases efficiency and enhances safety
Each year, the Battery Lifecycle Company site will recycle up to 15,000 metric tons of battery materials.
Battery Lifecycle Company is building Europe’s first fully automated plant at its site in Magdeburg, with Bosch Rexroth supplying the technology. The plant is scheduled to go into operation in summer 2023.
The site will test used batteries from different manufacturers, deep-discharge them, and prepare them for subsequent shredding. It will takes less than 15 minutes to automatically discharge eight lithium-ion batteries from electric cars. Bosch’s automated solution will greatly increase the speed of recycling: with the manual process currently used, it takes up to 24 hours to deep-discharge a battery. Battery modules will be chemically deactivated in a reliable process, ensuring that further processing can take place without voltage. The residual energy in the modules can be used to operate the recycling system. In addition, the site will use proven Bosch industrial technology for battery production on-site, including flexible, modular transfer systems and the ctrlX AUTOMATION control platform.
Bosch is equipping an increasing number of vehicle models with the 48 V battery performance, contributing to today’s and tomorrow’s sustainable mobility.
The primary function of the 48 V battery is to store the recovered brake energy and supply this energy boost to the vehicle while accelerating. The energy can also be used to power the vehicle’s electric drive system. Vehicle manufacturers reduce CO2 emissions by up to 15 % at very low cost.
