Presentation Description: Battery Electric Vehicles (BEVs) use a high-voltage DC battery to power the main loads and drive the traction inverter. Contactors and fuses are employed for power distribution within the vehicle and to protect against short circuits. Currently, mechanical contactors and fuses are used for this purpose. However, they are slow to respond, allowing high currents to pass through during short-circuit conditions, and are not very reliable for prolonged use. Additionally, battery voltage in EVs has increased from approximately 400V to 800V to reduce losses at high power and enable faster charging. This creates further challenges in implementing mechanical protection devices. As a result, automotive companies are considering transitioning to solid-state protection using robust power semiconductor devices. However, the lack of efficient, cost-effective bidirectional switches on the market is slowing this transition. B-TRAN™ technology, with its ultra-low conduction losses and cost-effective silicon process, is facilitating this shift.
