Bosch, the world’s largest automotive supplier is introducing silicon carbide (SiC) chips to help boost EV efficiency by about 6%. SiC semiconductors have better electrical conductivity. This enables higher switching frequencies while also ensuring that much less energy is dissipated in the form of heat.
The addition of carbon atoms to the silicon normally used for semiconductors increases the conductivity of microcircuits on each chip. For the PEM, these chips are used for switching the current polarity for the DC to AC and AC to DC conversion. SiC allows for higher switching frequencies and a 50% reduction in heat dissipation resulting in more power and less energy loss. The bottom line is 6% more driving range from the same battery charge. That means drivers can either go further or get the same distance with a smaller, lighter, cheaper battery.
