RACK INTEGRATION

Assemble seven packs into one
controllable, isolatable, and maintainable
high-voltage energy spine

From DC input, vertical series connection, and liquid-cooling distribution to RBMS addressing, pre-charge protection, and rack-level release, seven packs here become a truly controlled, verifiable high-voltage energy spine for the first time.

Seven packs here become a controlled high-voltage energy spine for the first time.

Seven positions form a real electrical series string Scan to locate; lock physical position and electrical sequence

Pack ID Status Location Measured outcome Offset Decision
PK-043 RELEASED R01 POSITION CONFIRMED 0.21 mm PASS

Pack 01: PK-043 has confirmed access to R01, mechanical position deviation 0.21 mm, which corresponds to electrical sequence.
• Scanning confirmation Bind Pack identity to rack position.
• Orientation and positioning Pack push and track match.
• Mechanical lockout Position fixed into As-Built.
