Bosch's latest Third-Generation SiC Chips to enhance EV efficiency and extend driving range in India.

EV manufacturers are constantly working towards increasing the efficiency and range of EVs in order to eradicate the range anxiety, boost the fast-charging capabilities and powertrain efficiency, as semiconductor technology is emerging as a crucial part of development of electric vehicles. 

Bosch’s third-generation silicon carbide (SiC) semiconductors are engineered to increase the performance and efficiency of EV power electronics. This is a big achievement in India’s electric-mobility ecosystem. Sample chips are currently being shipped to global automakers for testing with full commercial market availability targeted for 2027. 

20% Higher Performance 

Bosch’s third generation Silicon Carbide (SiC) chips are powered with dual-channel trench architecture, which is a specialised transistor design that improves current transmission efficiency and overall system power-conversion efficiency by lowering down the resistance and loss during device switching. 

These chips are designed to meet the growing demands of power efficiency and performance requirements of modern EVs. This technology also provides 20% more performance than previous generation chips. 

Bosch has stated that its new SiC technology helps in boosting real-world range, battery utilisation and reduces overall cost of ownership to owners of electric vehicles. The Silicon carbide technology can also reduce power loss which happens during the energy conversion process and thus can increase the power efficiency. 

The reduction of loss also decreases the heat generated inside the inverter, thus helping to lower the system’s cooling requirements. Thus this introduction of SiC chips is quite revolutionary as Indian manufacturers are looking for localised options for their EV technologies to make their EVs more affordable for Indian consumers. 

Thus advanced semiconductor devices like SiC MOSFETs can improve the inverter performance without the need of larger battery packs.
