Every electrified vehicle requires high-voltage electronics, providing core functions such as driving, fast charging, and battery management (BMS). The most sought-after qualities of electronics are high performance despite small dimensions and low weight. The answer lies in an up-integration and an application-specific use of innovative materials like gallium nitride (GaN) in the onboard charger and silicon carbide (SiC) in the inverter. High-end designs using chip-embedding and manufacturing processes such as silver based sintering are trademarks of a leading position in technology. As a result, electronics’ efficiency can reach up to 99% at specific operating points, while its spatial envelope can be reduced by up to 30% over several years. Based on the outstanding performance features of electronics one can utilize high charging currents without overheating, which helps to meet a key request from drivers: Faster charging.
On top of that Vitesco Technologies is advancing integrated modular electronics with a high level of re-use. The High Voltage Box, for instance, combines functions such as the onboard charger, DC/DC conversion and power distribution across the vehicle within a single cluster. Utilizing this principle of building clusters simplifies the high voltage architecture – with the added benefit that less cabling also saves weight.
