A 400-to-800-volt battery pack is not a drivetrain — it is a potential thermal runaway event sitting on the shop's floor. NHTSA recommends 50 feet of clear radius. NFPA guidance aligns. Most shops don't have the real estate, so they stack concrete ecology blocks at $85 each to build a quarantine bay. The OEMs require multimeter voltage verification, Class 0 lineman gloves, lock-out/tag-out logging. Insurers routinely refuse to pay for any of it. Agent 05 auto-generates the compliance checklist to the technician's mobile device the moment the VIN decodes as PHEV or BEV, logs every sign-off, and auto-populates the HV safety labor into the estimate — insulating the shop from ADAS/EV litigation exposure that now averages $200,000 to $1M+ settlements.
The modern electric vehicle does not arrive at the shop as a car. It arrives as a certified hazard: a 400-to-800-volt DC battery pack with stored energy sufficient to arc-weld steel, housed inside a structure that has just absorbed a collision. Before any technician touches a fastener, the vehicle must be high-voltage de-energized, multimeter-verified across the service disconnect, tagged out, and inspected for thermal signatures. Only then does the repair clock start.
The OEMs are explicit about what this requires. BMW's iX procedure, Ford's Mach-E procedure, Tesla's body repair manual, GM's Ultium guidance — each document mandates specific sequences involving Class 0 lineman gloves (rated to 1,000 volts AC), a verified digital multimeter reading at the HV service disconnect, a written lock-out/tag-out log, and in many cases a 24-hour observation period before structural work begins. Failure to execute any step is not a cosmetic violation — it is the actionable center of an EV liability lawsuit.
Litigation in this space has exploded. ADAS-related lawsuits grew from 3 in 2018 to 61 in 2024, with average settlements between $200,000 and over $1,000,000. EV battery fire cases are following the same trajectory. The repair shop is often named alongside the OEM because the shop is the last party documented to have handled the battery. If the shop cannot produce a compliance log showing multimeter verification, PPE utilization, lock-out/tag-out, and thermal monitoring, the shop's liability insurance carrier will not defend without reservation of rights.
Storage is its own arena. NHTSA's interim guidance for electric and hybrid-electric vehicles equipped with high-voltage batteries recommends that any EV with compromised battery integrity be stored outdoors, uncovered, with a 50-foot clear radius from other vehicles or structures, or inside a quarantine bay constructed of non-combustible barriers. The Washington State Patrol evidentiary bullpen approach — stacked concrete ecology blocks at approximately $85 each — has become the de facto industry standard for urban shops that cannot spare 50 feet of lot. A single quarantine bay costs roughly $2,400 in blocks alone before logistical handling.
None of this is optional. All of it is disputed by insurers. The daily hazard storage fee, the HV de-energize labor, the re-energize labor at closeout, the thermal monitoring log — carriers push back on every line, citing DRP matrices that predate widespread EV deployment. Shops that don't have documentation lose. Shops that do have documentation, submitted with the estimate at intake, get paid and stay out of court.
Agent 05's trigger is the intake VIN scan. CCC ONE, Mitchell, or any modern SMS emits the VIN at check-in. The agent listens for the decode payload. If the powertrain field returns PHEV (plug-in hybrid) or BEV (battery electric), the agent fires immediately. ICE vehicles pass through without action.
// POST https://agent.shop.local/webhook/vin-decoded { "event": "vehicle.checked_in", "ro_number": "2026-04-2201", "timestamp": "2026-04-22T08:14:33Z", "vin": "5YJ3E1EA9PF123456", "vin_decode": { "year": 2023, "make": "TESLA", "model": "Model 3", "trim": "Long Range AWD", "powertrain": "BEV", "battery_voltage": 400, "battery_chemistry": "NCA", "battery_capacity_kwh": 82 }, "loss": { "point_of_impact": "REAR_LEFT", "airbag_deployment": "NONE", "battery_compartment_impact": "POSSIBLE", "drivable": "LIMP_MODE" }, "assigned_technician": "tech_0417_miguel", "assigned_bay": "QUARANTINE_BAY_02" }
The agent does not require a modified SMS workflow. It listens to the existing VIN decode event that every major SMS already emits. Integration is passive. No new data-entry burden on the service writer.
Agent parses the VIN decode payload. PHEV and BEV trigger the full compliance workflow. Mild-hybrid (MHEV) triggers a reduced version (no quarantine requirement, but PPE and multimeter still required).
Agent pulls the vehicle-specific HV decommissioning procedure — Tesla Service Manual, Ford rotunda.com, GM Service Information, BMW TIS, Hyundai HMA, Lucid service docs — and extracts the ordered sequence: service disconnect location, multimeter target voltage, lock-out/tag-out requirements, thermal observation window.
If the impact was in a zone where battery compromise is possible (rear-underbody, side-pillar, heavy front), the agent flags the vehicle for quarantine routing. Logic: 50-foot open-air radius OR ecology-block quarantine bay OR OEM-specific isolation per interim NHTSA guidance.
Agent generates a mobile-ready digital checklist with the OEM-specific steps, enforced signoff order, and timestamp-required fields. Delivered to the assigned technician's phone via the CCC ONE Repair Facility mobile app or Mitchell Cloud Estimating mobile.
Agent writes four defensive lines into the estimate: Hazard Storage / Quarantine Bay, HV De-energize, HV Re-energize, and Daily Thermal Monitoring. Rates drawn from the shop's door-rate matrix. Line notes cite the OEM procedure number and NHTSA interim guidance.
As the technician completes each checklist item — multimeter reading photographed, PPE donned, lock-out applied — the agent archives the entries to an immutable compliance log. That log is the shop's legal shield when the vehicle is in a future lawsuit.
Two artifacts are produced simultaneously: a digital checklist on the assigned technician's phone, and four new lines in the CCC ONE workfile. Neither can proceed without the other — the estimate submission awaits the technician's multimeter-verified signoff on line 1 of the checklist.

| 003 | HV Re-energize / System Verification AGENT 05 | $85.00 |
| 004 | Quarantine Bay Storage · /day AGENT 05 | $95.00/day |

Across typical industry data, Agent 05 captures an average of $280 in HV safety labor per EV that gets disputed or dropped from estimates otherwise. On a two-day quarantine, that figure climbs with daily storage and monitoring lines. More importantly, the compliance log archived behind each line becomes the shop's defense document if the vehicle surfaces in litigation months or years later.
Class 0 lineman gloves are rated to 1,000 volts AC / 1,500 volts DC under ASTM D120. They are the minimum compliant PPE for handling any HV service disconnect on a 400V-to-800V vehicle. Gloves must be pressure-tested every six months and logged. OSHA 1910.269 is the governing federal standard; most OEMs reference it directly.
Multimeter voltage verification is non-negotiable. The technician must read across the HV service port and confirm a value below the OEM-specified safe threshold (typically < 60V DC). A Fluke 87V or equivalent CAT III 1000V / CAT IV 600V rated meter is the industry standard. The reading must be photographed and attached to the compliance log. "Trust the service disconnect" is not a compliant protocol.
Lock-out / tag-out follows OSHA 1910.147. The disconnect is physically retained by the technician performing the work; the tag is signed, dated, and not removed until all repair operations are complete and HV re-energize is authorized.
NHTSA's interim guidance: EVs with compromised battery integrity require a 50-foot clear radius outdoors, uncovered. For an urban shop with a 40-foot lot, this is geometrically impossible.
The Washington State Patrol evidentiary-bullpen approach solved this: stacked concrete ecology blocks (roughly 2'×2'×6', ~3,600 lbs each, approximately $85 per block) form a non-combustible three-sided perimeter. A standard quarantine bay is 12' × 20' with 8' walls — approximately 28 blocks, $2,380 in material before forklift handling. Per NFPA guidance, the bay must be covered by a water suppression or inert-gas flood system, drain to an isolated containment sump, and remain clear of stored combustibles.
Agent 05 knows the shop's bay inventory. It assigns the vehicle to an available bay at check-in, routes the tow driver, and starts the daily storage billing clock the moment the vehicle crosses the perimeter.
ADAS-related lawsuits: 3 in 2018, 61 in 2024. Average settlement range: $200,000 to $1,000,000+. EV battery fire cases follow the same trajectory. In every filed case, the plaintiff's discovery request includes the shop's compliance log. Shops that cannot produce the log settle. Shops that produce an immutable, timestamped, OEM-cited log win summary judgment.
Per-EV economics break into two layers. Layer one is the HV safety labor that gets disputed or dropped without documentation — averaging $280 per EV across de-energize, re-energize, and initial storage lines, before multi-day quarantines compound the number. Layer two is liability insulation: the compliance log is the document that keeps the shop out of a seven-figure settlement. The shop does not bill for that line. The shop survives because of it.
Line-item capture is the visible math. Litigation avoidance is the invisible math. One avoided settlement — even at the low end of the $200k range — covers the cost of running Agent 05 across a ten-location MSO for a decade.
Agent 05 runs on Anthropic's Routines framework. Integrations are designed around the mobile device the technician is already carrying — not a new piece of hardware, not a new app. The CCC ONE Repair Facility Android/iOS app and the Mitchell Cloud mobile client both expose the endpoints needed.
MISSION You are the High-Voltage EV Compliance Documenter. Your job is to protect the shop from EV liability exposure by enforcing OEM high- voltage safety procedures, delivering a verified checklist to the assigned technician, archiving an immutable compliance log, and auto-populating the estimate with the HV safety labor the shop is entitled to bill under OEM, NHTSA, NFPA, and OSHA authority. INPUT - ro_number: shop SMS repair order - vin: 17-char VIN - vin_decode.powertrain: ICE | MHEV | PHEV | BEV - loss.point_of_impact: impact zone code - loss.battery_compartment_impact: CONFIRMED | POSSIBLE | NONE - assigned_technician: tech ID for checklist routing - assigned_bay: shop bay ID STEPS 1. Parse vin_decode.powertrain. If PHEV or BEV, proceed. If MHEV, issue reduced PPE-only checklist. If ICE, no action. 2. Retrieve OEM HV decommissioning procedure for year/make/model. Parse: service disconnect location, target voltage threshold, lock-out/tag-out sequence, thermal observation window. 3. Evaluate loss.point_of_impact + battery_compartment_impact. If battery compromise is POSSIBLE or CONFIRMED, route to quarantine bay per NHTSA 50-ft / ecology-block logic. 4. Generate mobile checklist with ordered signoff items: - Class 0 PPE verification (photo required) - Service disconnect removal (OEM reference cited) - Multimeter voltage reading (photo + value required) - Lock-out/tag-out applied (tag ID required) - Vehicle staged in assigned bay - Thermal baseline captured (IR photo) - 24-hr observation window opened (auto-reminder) 5. Push checklist to assigned_technician via CCC ONE mobile API. 6. Write estimate lines: - HV De-energize / Service Disconnect (labor hours) - HV Re-energize / System Verification (labor hours) - Quarantine Bay Storage (per day) - Daily Thermal Monitoring Log (per day) Cite OEM procedure + NHTSA guidance in line notes. 7. As technician completes each checklist item, append to the immutable compliance log. Photo + timestamp + tech ID. 8. On final HV re-energize signoff, close the compliance log and stamp a 10-year retention lock. CONSTRAINTS - Never skip PPE verification. Multimeter reading is mandatory. - Never allow estimate submission until checklist item 1 (PPE) and item 3 (multimeter) are signed. - Every checklist signoff requires a timestamp + tech ID. - Compliance log is append-only. No edits, no deletions. - Quarantine bay assignment must respect existing occupancy. - Line notes must cite a verifiable OEM procedure number and the governing NHTSA / NFPA / OSHA reference. - If OEM procedure is unavailable, fall back to I-CAR HV guidance and flag estimator for manual confirmation.
