How Electric Vehicle Salvage Differs from Traditional Car Salvage

An internal combustion engine car that is severely wrecked is an inert object. Drain the fuel, disconnect the 12-V battery, and it cannot propel itself anywhere. An electric car is an entirely different creature. A wrecker’s yard containing a wrecked electric vehicle (EV) is full of high-voltage sources that could kill an inquisitive child long after the car was totaled. One reason an EV will be wrecked in the first place is that it has just taken a tremendous hit. Unless one was exceptionally lucky, the advanced driver-assist safety systems and physics dictate that either the car or some large obstacle had to give. However, because an EV can contain a minimum of 20 kWh of energy, and as much as 40 kWh, the operator cannot simply sever hydraulic connections, rip off the roof, and toss the 1500 lb object in the back of his tow truck as he would a typical ICE vehicle. The object has to be made safe.

A wrecked EV is still live

A typical ICE vehicle is mechanically inert relatively quickly. Drain the fuel, disconnect the 12 V battery, and it becomes a heavy piece of junk that is nonetheless benign. An EV is not so accommodating. The high-voltage battery in a Tesla, Nissan or Hyundai contains energy independent of the vehicle’s motion, its ability to run, or even its ability to be turned off. The high voltage battery, encased in orange wiring, can retain hundreds of volts even after the vehicle is wrecked.

This feature underlies all the other features on this list. This is the main reason why specialized training, equipment, and even staffing is needed if a yard wants to engage in EV wrecking.

Depowering replaces draining

In wrecking, certain standard safety procedures are taken, such as “draining the tanks.” In EV wrecking, similar – but extended – procedures have to be taken to “de-power the pack.” First, the low voltage battery is disconnected, then a high voltage service disconnect plug is sought and removed; it is a built-in feature on the vehicle for that purpose. Additionally, most manufacturers advise waiting before attempting to work on the high voltage pack, as the disconnect procedure only isolates the circuit, and capacitors downstream from the location still hold substantial current.

These procedures are not taken with ICE vehicles. Draining the gas tank is a similar procedure, but there is no waiting period involved. Additionally, the procedures taken for EV wrecking have to be well-documented, standardized, and often pulled from the Emergency Response Guide unique to the manufacturer, as they dictate the specific disconnect points, waiting periods, and even cutting instructions for each vehicle. Skipping steps or rushing the procedure leads to shocks, fires, or even thermal runaway events on batteries that appeared to have been isolated for hours with no issue.

Thermal runaway isn’t a fuel fire

A ruptured gas tank is a bad situation, but it has predictable consequences. It may result in a fire, but the danger is localized and relatively short-lived. A ruptured lithium battery cell, on the other hand, is a completely different animal. Thermal runaway events can occur days after the initial impact; the heat from a shorted cell can be enough to cause adjacent cells to experience the same issue. The entire pack can be involved in an intense fire that is exceedingly difficult to extinguish.

The only real solution is to store the vehicle isolated from the rest of the yard inventory with adequate spacing between other objects, as thermal runaway can occur unpredictably and with seemingly little cause. The same is not true of an ICE wreck with an emptied gas tank. One needs only look at the number of salvage yards that are able to store their vehicles in large compact masses to understand the fundamental difference. The storage footprint needed for an EV wreck is comparatively gigantic, and the associated costs are much higher.

Transport rules turn logistics into a regulated process

Transporting a wrecked ICE car from the scene of the crash to the salvage yard is a relatively straightforward affair. However, transport of a wrecked EV can have additional chemical-hazard regulations depending on the exact nature of the battery damage. The lithium battery itself, beyond a certain point, becomes a hazmat. Hazmat transportation has its own set of rules that usually involve classifying the shipment (UN 3480 and 3481 are the most common designations for battery electric vehicles), possible restrictions on the state of charge at the time of transport, marking and labelling requirements, and even quarantine procedures upon arrival.

Whether or not a quarantine is needed depends on the state of charge of the battery. A high SoC vehicle battery pack is the last thing a wrecker wants to be rolling out of their rollback wrecker, especially considering the potential for sympathetic thermal runaway events. The state of charge of the battery at the time of the incendiary incident directly informs the amount of energy that will be dumped into the flames. Similarly, the higher the SoC is at the time of an incident, the more likely it is that the battery cells will reach the temperatures needed to experience thermal runaway on their own due to the heat from their neighbors. Wreckers have to be acutely aware of the state of charge of any given battery, sometimes even before it is fully detached from the vehicle, as the number informs nearly all further procedures. ICE salvage does not involve this requirement. EV salvage does.

The value map flips upside down

In a typical wreck, the value of the car is measured in engines, transmissions, sheet metal, and glass. The battery in an ICE car – the 12-V battery – has virtually no value. An EV wreck has the value of its battery pack, which often represents 30 to 50 percent of the value of the entire vehicle, even one that was totaled in the crash.

This completely flips the script on what a wrecker views when looking at a wrecked vehicle. The first question out of his mouth when looking at a wrecked EV is no longer the condition of the body, but rather how good the condition of the pack is. A pack with no visible damage and intact modules could be worth more than the value of the entire vehicle, even one that was not wrecked at all. That could be regardless of whether the pack is resold whole, broken down into its component modules, or – in a particularly interesting twist – utilized in its entirety in a second-life storage application, where the performance of a full EV battery is not required, but the safety and quality of an OEM battery are still desirable. Battery pack prices have been plummeting throughout this decade; BloombergNEF’s 2024 survey puts the global average benchmark price at around US$115 per kWh in 2024, down over 90 percent since 2010. The value of the recovered pack components and the engineering that went into them is a significant draw for recyclers and wreckers that want to resell the equipment.

Used parts come with software attached

A used alternator or gearbox from an ICE car is a used part that will work in most vehicles of the same class. A used electric drive unit, onboard charger, or battery management system from an EV is often tied to that specific vehicle at a software level. That means that a part from a wrecked EV might have to be reprogrammed, unlocked, or professionally remanufactured before it can see any use in another vehicle. This represents an entirely new category of “used parts friction” that ICE wrecking did not have to contend with.

It is important to note that this is a real problem. A part might not be functional unless there is a software connection to the proper VIN. That part might have to be remanufactured before it can be resold or even used in a demonstration vehicle by the wrecker. This is a significant loss of potential value if a part cannot be resold at a reasonable price. It is also a significant source of inefficiency if that part could have otherwise seen use in a second-life storage application.

EV wrecking has become a specialist trade

Considering all that has been said above, it becomes evident that EV wrecking is not a variation on wrecking as a whole, but rather a separate and distinct procedure. High voltage qualifications, testing equipment, and appropriate training is not an add-on, but a necessary prerequisite. The additional costs to the operator – in both time and money – push specialization as a natural response, rather than having EV wrecking as a subsection of ICE wrecking performed by the same yards.

Tesla vehicles are the most prominent example of this phenomenon at the moment. Tesla vehicles are common on the road, exceptionally expensive to repair at official dealerships, and replacement parts from the manufacturer can be notoriously slow to arrive. This has created a demand for “Tesla Wrecking” – wreckers that specialize in the safe disposal of Tesla vehicles, with the end goal of either reselling the usable components or remanufacturing the vehicle for resale. Insurance companies tend to lean towards using genuine parts over aftermarket replacements wherever possible, and a wrecked Tesla with a good battery pack and drivetrain represents tremendous value that can be extracted with the right equipment and software knowledge. This is the entire point of the EV circular economy, demonstrated on a smaller scale and made more urgent by the overall cost of Tesla vehicles. The wrecking yard is the place where all these factors intersect in real-time on vehicles without the aid of a manual.

Recycling is the last step, not the plan

All of the points above tie into the same general principle. Whenever possible, the wrecked vehicle should be repaired. Whenever that is not an option, the components should be sold. Whenever that is not an option, the useful elements should be extracted or the whole object sent to second-life storage. Recycling should be the option of last resort, and even then, the value of the extracted materials should be weighed against the value of the components as a whole. The latter almost always outweighs the former, which is why second-life storage facilities always have an advantage over recyclers in terms of potential value retrieved from a single vehicle.

This is the fundamental difference between an EV wrecking yard and any other type of salvage yard. The two exist in different economic spheres, with the potential value of the materials being dwarfed by the potential value of the components. That is why the wrecking yard is the logical end-point, rather than the recycling yard. It is the final opportunity to extract value from the wrecked vehicle, and it is this potential value that drives the whole process from beginning to end.
