Can Electric Vehicles Be Jump-Started? Exploring Misconceptions Behind EV Breakdowns
Electric vehicles (EVs) are becoming more common on the roads every year. But when an EV won’t start, many drivers naturally ask: “Can I jump-start it, just like a regular car?” The short answer: it depends. EVs don’t have traditional engines, but they do have 12-volt batteries that can fail, just like a gas-powered car. Let’s clear up the confusion.
EVs Have Two Batteries
Most EVs (Tesla, Nissan Leaf, Chevy Bolt, etc.) actually have two batteries:
- High-voltage lithium-ion battery: Powers the electric motor and drives the car.
- Low-voltage 12-volt battery: Runs the electronics, locks, lights, infotainment, and even starts up the main system.
If your EV won’t power on, it’s usually the 12-volt battery, not the big one, that’s the problem.
Common Misconceptions About EV Breakdowns
Misconception #1: EVs Can Be Jump-Started Like Gas Cars
Most people think you can just connect jumper cables to an EV’s main battery, this is dangerous and incorrect.
- You should never jump the high-voltage battery.
- In some EVs, you can safely jump the 12-volt battery using another car or portable jump starter, but only if the manufacturer allows it. Always check the owner’s manual.
Misconception #2: A Dead EV Means You’re Completely Stranded
While it’s true that if the main battery runs out of charge, you can’t jump-start it, that doesn’t mean you’re stuck forever.
- Solution: You’ll need a tow to the nearest charging station or your home charger.
- Professional towing companies now use flatbed trucks designed to safely move EVs without damaging their motors or regenerative braking systems.
Misconception #3: Any Tow Truck Can Handle an EV
Not all towing methods are safe for electric cars. Wheel-lift towing, for example, can damage the drivetrain. EVs should always be transported on a flatbed tow truck to prevent costly damage.
What You Should Do If Your EV Won’t Start
If your electric vehicle does break down, follow these steps for the best outcome:
- Check the owner’s manual for jump-start instructions.
- Call roadside assistance or a trusted local towing company that understands EVs.
- Never attempt to tamper with the high-voltage system.
Final Thoughts
EVs are not immune to breakdowns. Knowing the difference between the 12-volt system and the high-voltage battery can save you stress, and money. If your EV won’t start, your safest bet is to call a professional towing and roadside service like Carsaad Towing, trained to handle electric vehicles the right way.
