Montreal's Free EV Battery-Health Clinic on August 15: What to Bring and What It Can Tell You
Montreal's Free EV Battery-Health Clinic on August 15: What to Bring and What It Can Tell You
Buying or selling a used EV without understanding its battery is uncomfortable. A dashboard range estimate can move with the weather and recent driving, while the expensive question sits underneath it: how healthy is the pack?
The Association des véhicules électriques du Québec, better known as AVÉQ, is trying a practical community answer. It will hold its first EV and battery-health clinic in Montreal on Saturday, August 15. Experienced owners and volunteers will use compatible diagnostic tools, when possible, to help participants understand information available from their vehicles.
The activity is free and does not require registration. It is also important to understand what it is not: AVÉQ describes a community knowledge-sharing activity, not a certified battery inspection or a warranty assessment.

What to bring
AVÉQ says participants can simply arrive on site. Its equipment requirements apply to volunteers, who are asked to bring a working OBD2 reader and a compatible application.
For a smoother visit, these are practical suggestions rather than organizer requirements:
- Bring the EV you want to understand and make sure its 12-volt system is operating normally.
- Bring your phone, charging cable, and any vehicle app you already use.
- Write down the symptom or question that brought you there, such as a recent range change, a warning light, or a used-EV purchase decision.
- Bring recent service or battery reports if you want help comparing information over time.
- Do not buy a diagnostic reader just for the event. Compatibility varies by vehicle, and the clinic is specifically recruiting volunteers who already have tools and experience.
If you are considering a used vehicle that you do not own, get the owner's permission before connecting any tool or recording vehicle data.
What an OBD2 check may tell you
An OBD2 reader connects to a vehicle's diagnostic port. With a compatible vehicle and app, it may expose battery or electronic-system parameters that are not shown on the normal dashboard. AVÉQ carefully says volunteers will attempt, when possible, to evaluate different parameters, including the general condition of the traction battery.
That wording matters. Different EVs expose different data, apps calculate and label values differently, and not every vehicle will work with every reader.
A useful session may help you:
- identify battery information the car makes available;
- read diagnostic trouble codes or other electronic-system data;
- put a range or performance concern into better context;
- understand which questions deserve a follow-up with a dealer or EV-qualified technician;
- learn what information to request before buying or selling a used EV.
The useful outcome is not necessarily one perfect battery-health percentage. It may be a better understanding of what the vehicle reports and what to investigate next.
What it cannot establish on its own
An informal scan should not be treated as proof of the battery's remaining life or as a complete inspection. It does not, by itself:
- certify the battery for a sale;
- determine whether a manufacturer must approve a warranty claim;
- physically inspect cells, cooling hardware, connectors, or collision damage inside the pack;
- guarantee future range or predict an exact replacement date;
- replace a professional pre-purchase inspection, service diagnosis, or road test;
- prove that a displayed range change is permanent degradation rather than temperature, speed, recent driving, tire pressure, or climate-control use.
If the scan reveals a warning code, a large unexplained change, or conflicting values, save the information and book a qualified inspection. Avoid clearing codes or changing vehicle settings before a technician can review them.

Why this first clinic matters
Battery uncertainty slows down the used-EV market. Owners need better ways to explain the condition of the vehicle they are selling, and buyers need something more useful than a dashboard guess. A free clinic cannot solve the entire problem, but it can make diagnostic information less intimidating and show people what a more rigorous inspection should include.
Because this is a pilot and AVÉQ says checks depend on compatible tools, nobody should arrive expecting every model to produce the same report. Arrive with a specific question, listen to what the data can support, and keep the limits in view.
