RELIABILITY & DURABILITY ASSESSMENT
EV Charging Connector
Illustrative durability assessment | mating cycles, ingress and thermal exposure
Sector
Electric mobility and charging infrastructure
Duration
6–8 weeks
Decision
Release pathway
Decision to be made
Decide whether a charge-connector design can progress to supplier nomination, whether the seal and locking interface need remediation, or whether the test sequence should be extended before release.
Project Context
A hypothetical charging-equipment developer is comparing two connector-seal configurations for a public charging unit. The design must retain locking behaviour and electrical stability after repeated mating, moisture exposure and elevated temperature conditions.
Evidence Scope
- 12 connector and receptacle pairs across two seal configurations
- 10,000 controlled mating cycles at a representative actuation rate
- Thermal dwell and moisture exposure inserted between cycle blocks
- Contact-stability, latch retention, seal condition and intermittent-fault review
Condition cascade
The sequence deliberately combines operation and exposure. Each block ends with a functional checkpoint so a fault can be located in the sequence, rather than appearing only in an end-of-test result.
Block | Applied condition | Gate before continuing |
|---|---|---|
A | Baseline mating force, lock engagement and electrical reference | All units within agreed start criteria |
B | 2,500 mating cycles | No uncommanded unlock or intermittent event |
C | Thermal dwell and moisture exposure | Seal and contact inspection pass |
D | 5,000 additional mating cycles | Compare contact-stability trend |
E | Final 2,500 cycles and ingress check | Nominate, remediate or extend |
How the Work Would Be Delivered
August Research would define the evidence need, scout and assess suitable external laboratories or field settings, align the protocol and sample handling, coordinate testing checkpoints, and translate the evidence into a decision-ready pack. August Research does not own the laboratories or field facilities used for this work.
Stage | Illustrative delivery activity |
|---|---|
Week 1 | critical-function definition and test-rig/provider review |
Weeks 2–5 | cycle blocks, exposure sequence and interim gates |
Week 6 | engineering review of any degraded interfaces |
Weeks 7–8, if required | confirmatory block and decision readout |
Illustrative Outputs
- Connector-level cycle record with timed fault and recovery log
- Condition-cascade summary showing where degradation emerged
- Evidence brief for supplier nomination and design review
- Recommended next test, design or supplier actions
Note:
This is a hypothetical illustrative engagement, not a client outcome. Sample counts, cycle counts, measurements, timing and possible outputs are conditional on the product, relevant standards, provider availability, specimen readiness, logistics and project scope. Accredited testing, regulatory interpretation and any formal conformity assessment remain the responsibility of appropriately qualified providers and responsible parties.
Research and Regulatory Context
The final test method would be selected against the connector type, operating environment and applicable product and safety standards. This illustration does not represent a certification programme or a universal durability claim.
Let’s Discuss Your Project
Tell us the product stage, expected service conditions, known failure concerns and the decision you need to make. We can shape an independent reliability evidence programme around the right facility, equipment and delivery route.
Illustrative timeline
This example is shown as 6–8 weeks. The actual timetable depends on external provider response times, equipment access, specimen availability, testing duration and any required approvals.
