Power management company Eaton announced its eMobility business has introduced the EVK Series, a new line of Bussmann series fuses. The new line of high-voltage fuses meets the requirements for use in the latest high-powered electrified vehicles (EVs) with ratings up to 1,000 volts of direct current (VDC) and 600 amps.
The series is designed with the future in mind as battery requirements increase and technologies, such as energy dense solid-state batteries, are introduced. Bussmann series fuses are available in eight different frame sizes, ranging from 15 amps for auxiliary components up to 600 amps for battery protection when the full application current is flowing. The fuses are designed to distribute heat away from weak spots, a key benefit for any fuse rating and especially critical for high-power fuses
The fuses are designed to manage and protect the charging systems of electric commercial, passenger and high-performance vehicles such as sports cars and large SUVs. They enable more advanced EV system architectures, and support vehicle acceleration and range, the company said.
Using its proprietary simulation testing, Eaton can verify proper fuse-life performance and reliability for the lifetime of the vehicle. When severe short circuits occur due to a fault, such as a crash or an insulation break, the fuses isolate all the available energy and safely interrupt the circuit. Current limitation is also important, as it restricts total fault energy, enabling downstream components in the system to survive the fault event.
Till Wagner, product manager, Electric Vehicle Power Switching and Protection, Eaton’s eMobility said,“Our Bussmann series fuses help ensure reliable protection of the circuit components. To provide optimal performance, we simulate driving and charging conditions unique to specific customers.”
