Advanced Electric Drive Technologies
At the core of Bosch’s EV engine manufacturing is its innovative electric drive system—the Bosch eAxle. This all-in-one solution integrates the electric motor, power electronics, and transmission into a single, compact housing. This reduction in components not only simplifies assembly but also improves efficiency, reduces weight, and optimizes packaging within various vehicle architectures—crucial for maximizing cabin space and vehicle performance.
Bosch has pioneered the use of silicon carbide (SiC) semiconductors within its power electronics, enhancing inverter efficiency to nearly 99%. By producing 800-volt drive systems, Bosch doubles the voltage found in conventional 400-volt systems, allowing faster charging, reduced heat loss, thinner cables, and more compact inverter sizes. These innovations translate into longer EV ranges and shorter charging times, critical differentiators in the electric vehicle marketplace.
Their latest electric motor technology uses oil-cooled i-pin bar winding, increasing power density by 35%, resulting in motors that deliver up to 460 kilowatts of power and 830 Newton-meters of torque with up to 98% efficiency. These motors enable sustained high performance, suitable for both commercial vehicles and premium passenger cars. The components are produced and assembled at Bosch facilities in Germany, China, and the U.S., demonstrating Bosch’s global manufacturing capabilities.
Manufacturing Footprint and Capabilities
Bosch operates multiple electric motor manufacturing plants globally, including key centers in Germany, China, and the United States. Notably, the Charleston, South Carolina facility commenced electric motor production in 2022 with plans to expand to meet the increasing market demand. Bosch is investing over $260 million in this plant to increase electrification product output, creating numerous jobs and supporting regional economic growth.
Across its manufacturing footprint, Bosch integrates Industry 4.0 principles, employing automation, advanced robotics, and digital quality assurance to ensure high production volumes without compromising precision. Bosch Rexroth, a Bosch subsidiary, offers specialized EV factory automation solutions, addressing assembly challenges for complex EV components such as battery packs and eAxles to accelerate production throughput and improve scalability.
Bosch’s ability to globally coordinate manufacturing, balancing local production with global supply chain efficiency, positions it well against peak industry demand while supporting OEM partners with flexible and reliable sourcing.
Market Impact and Ecosystem Integration
Bosch has secured over 90 electrification projects since 2018, supplying components for passenger cars, commercial trucks, and off-highway vehicles worldwide. The Bosch eAxle’s adaptability allows installation across various vehicle classes with quick customization to meet OEM requirements, significantly reducing development times and costs.
Bosch’s investment in electromobility exceeded €400 million yearly, reflecting its serious commitment to becoming a mass-market supplier of electric powertrain solutions. The company is not just an electric motor manufacturer but a provider of integrated electrification systems, including battery management, charging solutions, thermal management, and software integration—all contributing to a robust EV ecosystem.
Sustainability and Future Outlook
Bosch is committed to sustainable manufacturing practices, reducing energy consumption, emissions, and waste across its operations. Its electric motors and power electronics are designed to maximize efficiency and reduce carbon footprint while supporting the global agenda of reducing greenhouse gas emissions through electrification.
Looking forward, Bosch continues to invest in next-generation technologies such as solid-state batteries, fuel cell integration, and further power-train electrification advancements. Its strategic focus includes expanding capacity, integrating artificial intelligence into power-train control, and enabling more affordable, reliable, and high-performance electric vehicles to accelerate global adoption.
