High-voltage contactor switching logic: BYDRecent Research Landscape

Arcing and thermal stress during high-current transfer damage vehicle power electronics. These innovations utilize coordinated contactor sequencing to ensure safe galvanic isolation and load distribution.

What technical problems is BYD addressing in High-voltage contactor switching logic?

Undetected relay contact failure

(18)evidences

Inaccurate monitoring of contactor states leads to hazardous electrical conditions or system damage. Reliable state detection prevents catastrophic failure during high-voltage switching operations.

Unsafe high voltage maintenance access

(16)evidences

Sudden electrical connection in high-voltage vehicle systems causes destructive arcing and contact welding. Preventing these failure modes ensures system safety and component longevity.
