Auto-Generating Technical Data Sheets with Dhimath
How NeoVolt Uses Dhimath to Auto‑Generate EV Inverter Technical Data Sheets
How NeoVolt Uses Dhimath to Auto‑Generate EV Inverter Technical Data Sheets
NeoVolt Electric Systems Ltd. builds EV inverters, onboard chargers, and DC–DC converters for passenger and light commercial vehicles, with a rated capacity of 180,000 units per year and OEE at 72%. Their engineering and sales teams must routinely deliver precise Technical Data Sheets (TDS) for OEM RFQs, audits, and platform nominations—often under tight timelines and with zero tolerance for undocumented claims.
To solve the “specs scattered across PDFs” problem, NeoVolt deployed a Technical Data Sheet (TDS) Generator in Dhimath, powered by a curated project called NeoVolt EV Power Electronics – Technical Documentation. This project bundles electrical performance reports, environmental qualification, application limitations, compliance matrices, and BOM summaries into a single, queryable knowledge base.
What the TDS Generator Agent Is Designed To Do
In private mode, the agent acts as a strict TDS engine for NeoVolt:
Uses only internal documents (test reports, compliance matrices, limitation notes, BOMs).
Extracts claimable parameters (e.g., 75 kW continuous, 120 kW peak, 97.2% efficiency) without inferring or “filling gaps.”
Maps each parameter to evidence: electrical tests, environmental reports, or standards matrices.
Outputs a structured engineering format: Overview, Electrical, Mechanical, Thermal/Environmental, Compliance, Operating Conditions, and a “Usage & Compliance Decision Summary.”
In public mode, it behaves as a standards reference agent:
Lists applicable standards for EV traction inverters (IEC 61800‑5‑1, ISO 26262, IEC 60529, ISO 9001, ISO 14001, CISPR 25, IEC 60068 series).
Provides typical ranges (400–800 V DC, 50–150 kW continuous, 95–98% efficiency, IP67 ingress protection) and how these relate to industry expectations.
Supports gap analysis without turning public benchmarks into NeoVolt product claims.
In hybrid mode, Dhimath lets NeoVolt combine both: internal specs plus public norms, clearly separating “From NeoVolt documents” vs “From industry standards,” ideal for positioning in OEM technical discussions.
Private Mode in Action: Full TDS for NeoVolt NVI‑75
When NeoVolt asks:
“Generate a complete Technical Data Sheet for the NeoVolt NVI‑75 traction inverter suitable for submission to an EV OEM.”
the agent produces a standards‑aligned sheet in a single response:

6. Operating Conditions & Limitations
Key constraints are lifted from NeoVolt’s own Product‑Application‑Limitation‑Note.pdf.
Approved operating conditions:
DC bus voltage between 400 V and 800 V DC.
Ambient temperature −40°C to +85°C.
Coolant temperature ≤ 65°C with 8–12 L/min flow.
Derating conditions:
Coolant temperature > 65°C → linear power derating.
DC bus at 400 V → output power reduction.
Non‑approved applications:
Rail traction systems.
Aerospace propulsion.
Stationary industrial drives.
Warranty‑impacting misuse:
Operation outside specified voltage limits.
Insufficient coolant flow.
Unauthorized firmware modifications.
7. Usage & Compliance Decision Summary
The agent always closes with a management‑friendly decision block:
Approved use cases
Passenger EVs.
Light commercial EVs.
Regenerative braking traction systems.
Restricted use cases
Platforms operating under continuous derating conditions (coolant >65°C or DC bus near 400 V).
Applications awaiting EMI validation under CISPR 25 Class 3.
Not approved for
Rail traction, aerospace propulsion, stationary industrial drives.
Defense‑grade EV platforms (MIL‑STD compliance not claimed).
From NeoVolt’s perspective, this is a “ready to send” TDS to an OEM—generated in a single private‑mode answer, with response time visible on the screenshot.
Public Mode: Standards and Market Benchmarking
When the prompt switches to public mode:
“Based on industry expectations for EV traction inverters, are NeoVolt’s declared specifications generally aligned with market norms?”
the agent does not restate NeoVolt internal data as claims. Instead, it constructs a standards and expectations view:
Commonly Applicable Standards (Industry View)
Standard | Area of Focus | Applicability |
IEC 61800‑5‑1 | Adjustable Speed Drive Safety | Functional and safety compliance for inverters |
ISO 26262 | Functional Safety (ASIL) | Safety‑critical automotive systems |
IEC 60529 | IP Rating (e.g., IP67) | Water/dust ingress protection |
ISO 9001 | Quality Management | Manufacturing quality systems |
ISO 14001 | Environmental Management | Sustainable manufacturing practices |
CISPR 25 Class 3 | Automotive EMC | EMI/EMC performance in vehicle environments |
IEC 60068 Series | Environmental Testing | Thermal, vibration, shock, salt spray robustness |
Typical Specification Expectations
Parameter | Typical Range | Notes |
DC Input Voltage Range | 400–800 V DC | Common EV battery architecture |
Continuous Power | 50–150 kW | Mid/high‑power traction inverters |
Peak Power (30 s) | 1.5 × continuous | For launch/accel bursts |
Efficiency @ nominal | 95–98% | Required to minimize losses |
Switching Frequency | 10–20 kHz | Trade‑off between harmonics and thermal stress |
Max Phase Current | 200–500 A RMS | Depends on motor/platform size |
IP Rating | IP67 | Typical for under‑hood power electronics |
The public answer then comments that NeoVolt NVI‑75 aligns well with market norms for voltage range, power levels, efficiency (~97%), IP67, and thermal range (−40°C to +85°C), while highlighting EMI validation under CISPR 25 Class 3 as a pending gap.
This is exactly what you want for pre‑sales and product marketing: evidence that your numbers are in the right ballpark, without over‑claiming.
Hybrid Mode: Combining Internal Specs with Public Standards
A representative hybrid query:
“Summarize all usage approvals, restrictions, and compliance readiness into a one‑page decision summary for management.”
The agent merges:
Internal TDS and limitation notes (approved vs restricted vs not‑approved applications).
Compliance matrix (ISO, IEC, RoHS, CISPR) and customer requirement checklist for OEM X.
Public expectations (why CISPR 25 is critical for automotive EMC).
The resulting management sheet includes:
A crisp overview of NVI‑75 (EV traction inverter, 400–800 V DC, 75 kW continuous, 120 kW peak).
A compliance table showing ISO 26262 ASIL‑B, IEC 61800‑5‑1, IEC 60529 IP67, ISO 9001, ISO 14001, RoHS all marked “Compliant,” with CISPR 25 Class 3 marked “Planned/Test scheduled.
A risk note that pending EMI validation may block OEM acceptance for EMC‑sensitive platforms until completed.
This is the kind of view a VP Engineering or OEM program manager wants before signing off on platform adoption.
Why This Matters for EV OEM Engagements
By anchoring every spec to an uploaded report or matrix, NeoVolt’s Dhimath TDS Generator:
Eliminates copy‑paste errors between electrical reports, environmental tests, and sales decks.
Enforces claim discipline (“Not specified in provided documents”) whenever a value is missing, instead of guessing.
Surfaces compliance gaps early (like CISPR 25 Class 3 still pending) so sales doesn’t over‑promise.
Reduces TDS creation time from hours to seconds, visible right in your screenshots through response time stamps.
For NeoVolt, this means faster RFQ turnaround, cleaner OEM reviews, and a reusable pattern they can extend to onboard chargers and DC–DC converters using the same project structure.
