Handling EVs After a Collision

Electric vehicles present new challenges in the collision repair world. Unlike conventional cars, the presence of high-voltage batteries and their electronic systems means everyone involved, from first responders to tow operators, technicians, and insurance adjusters, needs to know what’s involved for safe handling. Missteps can endanger workers, delay repairs, or even worsen damage. 

Let’s outline the key stages of managing an EV after a collision and the responsibilities at each step.

Making the Scene Safe

The first people to deal with a crashed EV are often firefighters, paramedics, or police officers, and their primary responsibility is ensuring the safety of everyone on-site. With EVs, that means stabilizing vehicles and caring for occupants, but it also involves mitigating the risks posed by the high-voltage system.

Responders are trained to identify EVs by markings, badging, or VIN information. Once it’s identified, they secure the scene by disabling ignition systems and looking for potential hazards like leaking coolant, smoke, or sparking. Many EVs have first responder cut loops or clearly marked disconnect points that allow the high-voltage system to be immediately isolated. By pulling these disconnects, responders reduce the chance of battery fires or electrical hazards.

Another crucial step is controlling the surrounding environment. High-voltage batteries compromised in a crash can go into thermal runaway even hours after impact. Fire crews often monitor damaged EVs with thermal imaging and, if necessary, submerge the pack or use suppression agents to ensure the vehicle can be safely released to recovery crews.

Tow and Recovery Protocols

Once the vehicle leaves the crash scene, the responsibility shifts to tow operators. Moving an EV requires special precautions that don’t apply to gas-powered cars. Standard practices like dragging a disabled car onto a flatbed with its wheels locked can actually cause more damage to an EV’s drivetrain or cooling systems.

Tow companies need equipment rated for the vehicle’s weight since EVs tend to be heavier due to the battery pack. Wheel-lift or flatbed towing is recommended, with dollies used if wheels are locked. Operators also need to check for OEM transport info as some EVs require a tow mode activated to protect the transmission or motor assemblies.

Equally important is where the car is stored once transported. If the high-voltage battery has been damaged, it may still pose a delayed fire risk. Many insurers and OEMs now recommend quarantining EVs in outdoor lots at least 50 feet from structures until an inspection clears the battery. 

Check for Surface Charge and Initial Safety Steps

When a damaged EV arrives at the shop, the first task is verifying the electrical system’s status. Even if the 12-volt system has been shut down, surface charge can remain in the high-voltage components for several minutes or longer. Technicians need to use insulated tools and protective equipment to measure residual voltage and confirm the system is actually completely de-energized.

Shops should establish intake protocols specific to EVs that could include isolating the vehicle in a designated area, posting warning signs, and restricting access until it’s confirmed safe. Technicians should also visually inspect it for obvious battery damage, coolant leaks, or odors that could indicate some kind of chemical release. Proper documentation at this stage protects both the shop and the customer.

Battery Integrity Checks

After confirming it’s safe, the next step is assessing the condition of the high-voltage battery. A battery pack is the most expensive component in an EV, and damage to even a portion of the pack can have significant financial implications. Getting this right is critical for both repair accuracy and insurance settlements.

Technicians need to evaluate cell balance, charge acceptance, and overall state of health. Diagnostic tools provide data that goes beyond visual inspection, catching internal faults that could lead to failure later. For insurers, this data is invaluable as a pack that appears intact but shows a serious imbalance may not be reliable long-term, and replacement could be justified.

Close collaboration between shop staff and insurance adjusters ensures repair estimates are transparent and accurate. It helps boost customer confidence when diagnostic printouts are shown rather than giving vague explanations. It reduces disputes, accelerates claim approvals, and prevents comebacks months down the road.

Additional Considerations

While high-voltage battery safety takes top priority, collision repair of EVs involves several other unique considerations:

  • Cooling systems – EV batteries and drivetrains rely on liquid cooling. Damage to lines or radiators compromises thermal management and must be repaired before the vehicle is safe to operate.
  • High-voltage wiring – Cables routed underbody can be pinched, cut, or exposed in a crash. Even if insulation looks intact, resistance testing confirms their integrity.
  • ADAS systems – Many EVs come loaded with advanced driver assistance technologies that require recalibration after body repairs.
  • Structural repair – EV frames are engineered to protect battery packs in crashes. Technicians need to follow OEM repair guidelines to the letter as improper sectioning or welding can weaken protective structures.

Each of these areas highlights why specialized EV training and equipment are no longer optional in modern shops.

The Role of Training and Communication

Every person in the chain of handling EVs, from first responders to insurers, needs the knowledge to spot risks and the confidence to act appropriately. Ongoing training is of the utmost importance: tow operators should understand manufacturer-specific tow modes, technicians should refresh high-voltage safety certifications, and service advisors should learn to communicate EV-specific issues clearly to customers.

Equally important is communication. Shops should create clear intake forms and customer handouts explaining why additional EV-specific steps are necessary. Being transparent about safety checks and diagnostic processes not only builds trust but also positions the shop as an authority on EV repair.

Turn Risk into Routine

EVs after a collision present more layers of complexity than traditional cars, but with the right process and EV-specific tools, they can be handled safely and efficiently. From the scene of the crash to the final insurance estimate, every stage requires awareness of the 12-volt system, the high-voltage pack, and the cooling and structural systems that keep them stable. Emergency responders, tow operators, technicians, and adjusters all play essential roles in keeping risks contained.

With standardized procedures, proper equipment, and tools from trusted providers like Midtronics, shops can transform EV collision handling from a source of anxiety into a reliable routine. That shift not only ensures safety but also builds long-term customer trust in the electrified automotive world.
