The high-voltage system comes first, before anyone touches a panel
The first difference is invisible. An EV carries a battery at several hundred volts and cables, marked orange, that run under the floor and into the motors and chargers. Before any cutting, welding, grinding or panel removal, the high-voltage system must be shut down and isolated using the manufacturer’s procedure for that model, and it must be confirmed de-energized with the right equipment. The person doing that wears rated gloves and works to a written sequence. Nobody else touches the car until it is done.
This changes the first day of a repair. A conventional car is unloaded, pushed into a bay and the tear-down begins. An EV goes through its isolation first, and if the car arrived on a tow truck after a hard hit, it may be held in a separate area until the battery has been assessed, because a damaged pack that is still energized is a fire risk that has to be managed rather than assumed away.
Once isolated, the body work itself looks familiar. Panels come off, the structure is measured, and the damage is documented for the insurance company in exactly the way it would be for any other car.
The battery pack is inspected after underbody and side hits
The pack is the floor of the car. It sits in a protective tray between the sills, and on many EVs it also carries structural load. A curb strike, a pothole hit that bottomed the car out, running over debris on the 401 or a side impact into the sill can all reach it without leaving much to see from the outside. So an EV that has taken a hit low down or from the side gets its pack inspected as a matter of course: the underbody shielding is examined, the pack casing is checked for dents and cracks, and the car is scanned for isolation faults and cell warnings.
The result decides the whole claim. A pack that is undamaged means a normal body repair. A pack that is compromised is often the single most expensive part of the car, and its replacement cost can push an otherwise repairable vehicle to a total loss. We describe that honestly to you and to the adjuster, because the decision is made on the numbers and the numbers need to be right.
Aluminum and structural adhesive change how panels are fixed
Many EVs use aluminum for the body panels, the castings at each end, and the structure around the pack, to claw back the weight of the battery. Aluminum does not behave like steel. It does not stretch and return the same way, it work-hardens when pushed, it cannot be welded to steel, and it needs its own set of tools kept away from steel dust so the two metals never contaminate each other. Where a steel fender might be repaired, an aluminum one is more often replaced.
Where the structure is joined, EVs and many newer cars use structural adhesive and rivets alongside or instead of spot welds. Those joints are repaired by following the manufacturer’s procedure exactly, with the specified adhesive, the specified rivets, and cure times that cannot be rushed. Some structural sections are designated non-repairable and must be replaced as a whole, and on some models that replacement is restricted to the manufacturer’s own network. The Tesla page describes how we handle that when it applies.
Parts lead times stretch the schedule
EV parts come from fewer places, and some come from only one. A bumper cover for a common gasoline sedan can be on the shelf in Scarborough tomorrow; the equivalent for an EV may be on order from a distribution centre out of province and arrive in a couple of weeks. Structural castings, battery components, and sensor assemblies can take longer again. We order everything on day one and tell you the real expected date, and if a part slips we say so rather than letting you find out at the end.
Plan for a longer time without the car. If you are not at fault, or you carry loss-of-use coverage, the rental runs for the duration of the repair, and we time the drop-off so the car is not sitting here waiting for parts while your rental days tick away.
What stays exactly the same
Paint is paint. The booth, the colour matching, the blending into adjacent panels and our lifetime warranty on the finish apply to an EV exactly as they do to anything else. The claim runs the same way: you choose the shop, we deal with the adjuster, and DCPD applies when you are not at fault. And the car that leaves should look and drive as it did before, with the driver-assistance systems recalibrated where the procedure requires it. The guide on EV body repair differences covers the ground in more detail.
Questions people ask
Is an EV more likely to be written off after a collision?
It depends almost entirely on the battery. If the pack is undamaged, repair costs are comparable to a similar gasoline car with some extra for isolation and aluminum work. If the pack is damaged, the replacement cost frequently exceeds what the insurance company is prepared to spend.
Can an EV be towed like a normal car?
It should go on a flatbed. Dragging an EV with the drive wheels on the ground can damage the motor. Tell the tow operator it is an EV and that you want it delivered to Crash Consultant at Sheppard and Don Mills.
Does my EV need to be charged when I drop it off?
Some charge is helpful, because the car needs to power up for scanning and for moving between bays, and because calibration often includes a road test. A quarter charge is plenty; do not leave it at zero.
Are EV repairs slower in winter?
The parts wait is the same in any season, but cold weather adds to it because the EV must be charged and warm for scanning and road testing, and paint cure is slower. Winter timelines are quoted as ranges for that reason, and we set one at the start.
