Firmware Testing Shouldn't Require Physical Danger

Every firmware engineer knows: the edge cases you can't test in the lab are exactly the ones that fail in production.

⚡Dangerous Scenarios

• Overcurrent testing risks $8k+ chargers
• Ground faults can injure technicians
• Thermal runaway needs isolation chamber
• Insulation breakdown is destructive

🐌Slow Iteration

• 1 test run = 45 min setup + teardown
• Can't test at 3 AM (lab closed)
• 1 charger = 1 test at a time
• Hardware resets take 5+ minutes

💰Expensive Failures

• OCA certification: €7,500 per attempt
• Failed cert = 3-month delay
• Production bugs = $50k+ recalls
• Physical chargers: $10k-$50k each

Real Cost: Failed OCA Certification

One firmware bug discovered during OCA certification costs you €7,500 + 3 months of delay. Testing against Gridmock's OCA compliance scenarios beforehand: $499/month.

15:1 ROI

One avoided failed certification pays for a year

Test Scenarios Impossible in Physical Labs

Gridmock simulates the CSMS side of dangerous or hard-to-reproduce scenarios

⚡

Electrical Fault Handling

•Ground Fault: EV charger detects ground fault, sends error code, expects CSMS to log + alert
•Overcurrent Protection: Charger hits current limit, must gracefully reduce power or stop
•Emergency Stop: CSMS sends immediate stop, charger must respond in <100ms
•Connector Lock Failure: Can't unlock cable, user trapped

📡

Network Failure Modes

•Mid-Transaction Disconnect: Connection drops during active charging session
•Intermittent Connection: Connect/disconnect every 30 seconds
•CSMS Timeout: CSMS stops responding, charger must handle offline
•Delayed Responses: 5-second lag on every CSMS response

📦

OTA Update Scenarios

•Update During Session: CSMS triggers firmware update while car is charging
•Corrupted Download: Firmware file MD5 mismatch, must reject
•Download Interruption: Connection drops at 80% download
•Rollback Test: New firmware fails, must revert to previous

🔐

Auth & Authorization

•Expired RFID Card: User swipes card that was valid yesterday
•Blocked User: CSMS returns "Blocked" status, must deny charging
•Offline Auth Fallback: No connection, use local whitelist
•Race Condition: User swipes card, unplugs, swipes again in 2 seconds

100+ pre-built scenarios covering OCA OCTT test cases, real-world failures, and manufacturer-specific edge cases.

OCA Certification Prep

Run the exact same test cases used in official OCA OCTT certification—before paying €7,500

Without Gridmock

Submit firmware to OCA for testing: €7,500

Wait 4-6 weeks for test results

Discover failures in test case #14 and #27

Fix bugs, wait 3 months, pay another €7,500

With Gridmock

Run all 50+ OCA test cases locally: 8 minutes

See failures immediately with detailed logs

Fix bugs, re-run tests in CI/CD until all pass

Submit to OCA with confidence—pass first time
