Verification & Validation

Why Verification & Validation Matter ?

A lithium battery pack is not simply a combination of cells and a BMS.
Without proper Verification & Validation during the prototype stage, risks often appear after the product enters the market,
leading to delays, redesigns, or safety issues.

CMB’s Verification & Validation service identifies and controls risks early — before they become costly problems.

Safety Risks

Overcharge and over-discharge
Short circuit
Thermal runaway

Performance Risks

Capacity loss at low temperatures
Peak discharge failure
Insufficient power under load

Regulatory Risks

Failure to meet IEC 62133, UL standards
Certification delays caused by late-stage design issues

Our role is to find these risks in the prototype phase — not in the field.

CMB Verification Service

Verification ensures the battery pack is designed and built correctly
based on your specifications.

Our engineering team confirms:

✔ Cell selection meets required capacity and discharge rate
✔ BMS protection logic matches the cells
✔ Wiring, connectors, and internal layout meet safety requirements

CMB Validation Service

Validation confirms reliable performance in real usage conditions —
not just controlled test environments.

Based on your application, we conduct tests such as:

✔ Low & high temperature performance (-40°C to 85°C)
✔ Discharge rate and peak current capability
✔ Environmental or waterproof protection (if required)
