Full EV Battery Pack Replacement

Removal and installation protocols for 400V/800V battery packs, coolant purging, and BMS ECU pairing.

Battery Pack Replacement Procedure

Full battery pack replacement occurs when State of Health (SoH) drops below operational limits ($<70\%$) or following severe structural underbody pack damage.

Installation Requirements:

  • High-Capacity Insulated Table: Utilizing 1500 kg rated insulated battery lifting tables.
  • Vacuum Coolant Purging: Refilling dielectric coolant circuits using vacuum pumps to prevent air locks in battery cold plates.
  • CAN Network & VIN Pairing: Coding master BMS ECUs with vehicle VIN cryptographic keys using OEM diagnostic tools.
