As part of a strategic collaboration with Mercedes-Benz, onsemi provides the carmaker with high-efficiency silicon carbide (SiC) power modules that increase the range of its VISION EQXX
onsemi announced that Mercedes-Benz adopted onsemi silicon carbide (SiC) technology for traction inverters as part of a strategic collaboration. onsemi’s VE-Trac SiC modules increase the efficiency and lowers the weight of the all-electric Mercedes-Benz VISION EQXX’s traction inverter, extending the electric vehicle’s (EV’s) range by up to 10%. The EV completed a 1,202 km (747 mile) trip from Stuttgart, Germany to Silverstone, England, holding the record for longest distance traveled on a single charge.
The VISION EQXX sets new standards for electric range and efficiency, while remaining sustainable and luxurious – and consuming less than 10 kWh of energy per 100 km (62 miles). This was achieved by a benchmark drag coefficient of just 0.17, lightweight design, reduced rolling resistance and the use of a battery that stores 100 kWh in 50% less space (and with 30% less weight) than comparable batteries. Key to the unprecedented range is an electrical system that ensures that 95% of the energy stored in the traction battery reaches the wheels – a huge improvement over internal combustion engine (ICE) vehicles that are only able to achieve around 30%.
A core piece of differentiation is the expertise in packaging, which is critical for improving heat dissipation and increasing power output at a smaller footprint than the closest competitor, as well as reducing the weight and cost of a power module. onsemi is the only large-scale supplier of SiC solutions with end-to-end supply capability, which includes volume SiC boule growth, substrate, epitaxy, device fabrication, best-in-class integrated modules and discrete package solutions.
