Most people assume EV breakdown works like petrol breakdown. It does not. Here is what actually happens and the scenarios that catch drivers off guard.
The single biggest difference, no flat-towing
Most electric vehicles cannot be towed on their own wheels. The electric motor is connected directly to the driven wheels, and when those wheels rotate without the car being powered, the motor generates electricity potentially overheating components or damaging the drivetrain.
EV breakdown recovery requires a flatbed truck, where all four wheels are lifted off the ground. This is more expensive and requires specialist equipment that not every breakdown provider routinely carries.
If your breakdown policy does not specifically confirm flatbed recovery for EVs, it may not be adequate for the car you are about to buy.
The most common breakdown: the 12V battery
The most frequent EV breakdown is not a flat main battery. It is the 12V auxiliary battery a small, conventional lead-acid battery entirely separate from the large main traction battery.
This battery powers the car's onboard electronics, door locks, and critically, the systems that allow the main battery to operate the car.
When the 12V fails, the car cannot start and may not unlock despite showing 80% or more charge in the main battery.
It is a jarring experience for drivers who do not know this battery exists. The fix is straightforward and the battery is inexpensive, but diagnosis on the phone with a breakdown call centre that has not been told the car is an EV can delay resolution.
State clearly what you suspect, and state that the car is an EV.
Running out of charge
Roadside charging top-ups from a breakdown technician provide a small amount of energy enough to reach the nearest public charger, not a meaningful recharge.
If the nearest charging point is not within a few miles, a flatbed to a charging facility is the more practical outcome. Plan journeys with charging stops built in and never ignore the low battery warning.
Tyres
Most EVs have no spare wheel only a foam sealant kit. Sealant handles small punctures. It cannot handle a blowout or significant structural tyre damage. A tyre blowout on an EV means recovery.
EV tyres wear faster than petrol equivalents due to vehicle weight and instant torque, making this a more common scenario than many buyers expect. Check what is in the boot when you buy if the sealant has already been used and not replaced, the car has no puncture recovery capability at all.
After a collision
State immediately that the car is an EV. A significant collision may trigger automatic high-voltage isolation the car will not drive until assessed by a qualified technician.
This is a designed safety response. Recovery must be by flatbed. If the car has been through flood water, do not attempt to start it wait for specialist assessment
