Water-cooling leak testing for battery PACK production lines
A short technical note from the legacy resource library covering why water-cooling leak testing matters in PACK production and what buyers should clarify before RFQ.
Document objective
What this file should help verify
Help PACK line buyers understand why water-cooling leak testing should be clarified before equipment scope, EOL planning, and acceptance reporting are finalized.
Why cooling leakage can become a safety and reliability risk in PACK projects.
What to ask about pressure decay testing, coolant-flow verification, reporting, and MES linkage.
How leak testing connects to broader PACK line acceptance and EOL evidence.
Process checkpoints
Use the file to review these engineering decisions.
01
Clarify whether the PACK design uses liquid cooling and where leakage risks appear in the assembly or final test flow.
02
Ask how pressure decay, coolant-flow verification, reporting, and NG handling are connected to line acceptance.
03
Confirm whether leak-test records need to connect with MES, traceability, and customer acceptance documents.
RFQ fields
Prepare these inputs before contacting a supplier.
Cooling plate or channel design
Leak-rate requirement

Cycle time target
NG handling
Data export need
Buyer FAQ
Questions this template should answer.
Is leak testing part of the PACK line or a separate test process?
It depends on the product and acceptance plan. Buyers should define whether it belongs inline, at EOL, or in a separate validation process.
What should be prepared before asking for a quote?
Prepare the cooling structure, sealing method, required leak rate or standard, target cycle time, and how test data should be recorded.
