New Fuel Cell Solutions for Buses 

In the hydrogen technology sector, Bosch is introducing new fuel cell systems for buses. The portfolio features systems ranging from 100 to 300 kW, designed for everything from city transit to long-haul travel. 

The compact FCPM C100 variant was specifically developed for city buses; with a height of only 16 inches (40 cm), it can be easily mounted on the vehicle roof. It is suitable for buses between 40 and 60 feet (12 to 18 meters) long and, according to Bosch, offers seamless integration. The C100 is based on the FCPM C190 variant for intercity and touring coaches, which will begin testing in demo vehicles in the first half of 2026 with a traditional rear-engine layout. Finally, the FCPM C300, with its 300 kW system output, serves as the primary power source for heavy-duty trucks and large coaches. 

800-Volt Electric Drive for Heavy Logistics 

Parallel to its hydrogen efforts, Bosch is presenting a new high-voltage battery-electric drive for heavy commercial vehicles and machinery, designed for system voltages up to 800 volts. This solution is particularly aimed at intralogistics applications, such as those found in logistics centers, ports, and distribution facilities. 

The 800-volt drive system consists of the SMG230 electric motor and a highly efficient inverter featuring silicon carbide power modules. The motor is designed for system voltages ranging from 400 to 850 volts. Within its ideal voltage and temperature range, it provides a continuous output of 252 hp (188 kW) and approximately 184 lb-ft (250 Nm) of torque. According to the company, it can briefly deliver up to 405 lb-ft (550 Nm) of peak torque. 

Bosch notes that the 800-volt technology has significantly increased power density. Compared to a similar 400-volt machine, the new motor provides up to 107 hp (80 kW) more power at the same weight—or, at the same power level, offers a much more compact footprint and significantly lower weight.
