Engineering-grade care for EVs and hybrids.

Ottawa's automotive practice built on a PhD in control engineering and hands-on Motive Power training — not just an oil-change crew.

What we do

Diagnostics and consulting for the electric era

01

EV & Hybrid Diagnostics

In-depth assessment of battery management systems, power electronics, and control units — the parts of a modern vehicle that a general shop isn't equipped to read.

02

Pre-Purchase Inspections

Buying a used EV or hybrid is a different exercise than buying a gas car. We check the systems that actually determine long-term reliability and resale value.

03

Fleet & Business Consulting

Advising fleets and small businesses on electrification planning, charging infrastructure, and maintenance strategy as they transition away from combustion vehicles.

04

Owner Education

Workshops and one-on-one sessions for EV and hybrid owners who want to actually understand what's happening under the hood — or under the floor pan.

Founder & Lead Diagnostician

Da Hai Automotive

Before he ever opened a set of bay doors in Ottawa, our founder spent decades solving hard technical problems on paper and in the lab. A master's degree in electrical engineering from the University of Wales — recognized as equivalent to a Canadian master's by World Education Services — gave him the fundamentals. A PhD in control engineering gave him something rarer: a deep understanding of how modern systems sense, decide, and act in real time.

That's not a coincidence for this business. A modern EV or hybrid isn't really an engine with some wires attached — it's a network of control systems, sensors, and power electronics that behaves more like a computer than a car. Most shops are trained on the mechanics of the old world. We start from the control theory of the new one.

To connect that theoretical depth with the practical reality of a shop floor, he went back to school — this time at Algonquin College, training hands-on in automotive systems alongside instructors and classmates decades younger. Da Hai Automotive exists to put both halves of that experience to work: the technical grounding to understand exactly what's happening inside an EV's battery pack, and the hands-on skill to actually do something about it.

MSc, Electrical Engineering

University of Wales — Canadian equivalency confirmed by World Education Services (WES)

PhD, Control Engineering

Doctoral research in the systems that govern how machines sense and respond in real time

Motive Power Technician Diploma

Algonquin College, Ottawa — hands-on automotive systems training

Automotive Service Technician (310S)

Currently completing Ontario certification through Skilled Trades OntarioIn progress

Engineering-first diagnostics

We read the control systems and electronics most shops can't, because that's where a modern EV actually lives.

Hands-on trained

Real Motive Power training at Algonquin College backs up the theory — not just a research background.

Ottawa-based

Locally owned and built to serve Ottawa's growing base of EV and hybrid drivers.
