Can You Jump Start a Car with an Electric Car
Short answer
Yes, you can jump start a car with an electric car, but it depends on the electric vehicle’s design and the situation. Some electric cars have a 12-volt battery system to assist with jump starting, while others do not. It’s important to follow specific procedures and check your electric car’s manual before attempting this.
What Does It Mean to Jump Start a Car with an Electric Car?
Jump starting a car traditionally means using a working vehicle’s battery to provide a boost of electrical energy to a dead or weak 12-volt car battery. This helps start the engine. When using an electric car for this, the electric vehicle (EV) acts as the “booster” source instead of a gasoline-powered car. Many electric cars still have a conventional 12-volt battery that powers lights, locks, and control systems, separate from their large high-voltage battery packs used for driving. This 12-volt system is what can potentially provide a jump start to another vehicle’s dead battery.
How Does Jump Starting Work with an Electric Car?
Jump starting with an electric car involves connecting jumper cables from the electric car’s 12-volt battery terminals to the dead battery terminals of the car that won’t start. The electric car’s 12-volt battery powers the cables, sending current to the dead battery to help start its engine. For example, say you have an EV with a charged 12-volt battery and a traditional car with a dead battery. You would:
- Park both cars close but not touching.
- Turn off both vehicles.
- Attach the red (positive) jumper cable to the positive terminal of the dead car battery, then to the EV’s positive terminal.
- Attach the black (negative) jumper cable to the negative terminal of the EV’s battery, then to a metal ground point on the dead car’s engine block (not the negative battery terminal).
- Wait a few minutes, then try to start the dead car.
- Once running, carefully remove cables in reverse order.
This process depends heavily on the electric car’s 12-volt battery capacity and design. Some EVs have safeguards to prevent jump starting other cars to protect their electrical systems.
Why Does Knowing This Matter for You?
Understanding whether your electric car can jump start another vehicle is useful in emergencies, especially if you’re the first on the scene with a dead battery situation. Since electric cars are becoming common, knowing how to safely use one for jump starting can potentially save time and avoid the need for roadside assistance. It also helps avoid damaging your electric car’s electrical system by using incorrect procedures or trying to jump start a vehicle that’s incompatible. This knowledge is practical for general adult drivers who may encounter dead batteries with their own vehicle or others.
What Are Some Terms People Confuse with Jump Starting Using an Electric Car?
- Hybrid Vehicle Jump Starting: Unlike fully electric cars, hybrids combine gas engines and electric motors. Most hybrids have a traditional 12-volt battery capable of jump starting another vehicle, but procedures vary.
- High-Voltage Battery: This large battery powers the electric motor in EVs but is separate and isolated from the 12-volt battery. It cannot be used for jump starting.
- Charging vs. Jump Starting: Charging an electric car’s high-voltage battery is different from jump starting a 12-volt battery and requires specialized equipment.
- Boosting: Some people use boosting and jump starting interchangeably, but boosting usually means using a battery charger or portable booster pack, not another vehicle.
Understanding these distinctions avoids confusion and prevents unsafe attempts.
What Should You Do Before Attempting to Jump Start with an Electric Car?
- Check Your Electric Car’s Owner Manual: Look specifically for sections about the 12-volt battery and jump starting. Some EVs explicitly warn against jump starting other cars.
- Inspect the 12-Volt Battery Condition: If your EV’s 12-volt battery is weak or low, it may not provide enough power for jump starting.
- Use Proper Jumper Cables: Use cables rated for automotive jump starting with insulated clamps.
- Follow Safety Guidelines: Turn off both vehicles, avoid sparks near batteries, and be careful with cable connections.
- Know When to Call for Help: If unsure or uncomfortable, contact roadside assistance or a professional.
Taking these steps protects both vehicles and people involved.
How Can You Safely Jump Start a Car with an Electric Car?
To jump start safely using an electric car, follow these recommended steps carefully:
- Park the two vehicles close but not touching.
- Turn off both cars and remove the keys.
- Put on safety gloves and glasses if available.
- Connect cables in this order: Red cable to dead battery positive terminal Red cable to EV’s positive terminal Black cable to EV’s negative terminal Black cable to grounded metal surface on dead car
- Wait 3-5 minutes for charge transfer.
- Try to start the dead car.
- If it starts, carefully disconnect cables in reverse order.
- Let the revived car run for 15-20 minutes to recharge the battery.
- Monitor for any electrical issues afterward.

What If Your Electric Car Cannot Jump Start Another Vehicle?
If your electric car isn’t set up to jump start other cars, don’t try to force it. Instead:
- Use a portable jump starter pack designed for 12-volt batteries.
- Call roadside assistance for help.
- Push-start a manual transmission car if safe and feasible (not possible with automatics).
- Ask for help from another gasoline or hybrid vehicle that can provide a jump.
Trying to use the wrong method can damage your EV’s electrical system or cause injury. Always prioritize safety and follow manufacturer guidance.
Frequently asked questions
Can all electric cars jump start a regular car?
Not all electric cars can jump start a regular car. Only those with a 12-volt battery system designed to supply jump start power should be used. Always check your EV’s owner manual.
Is it safe to jump start a car with an electric car?
It can be safe if done properly following the car manufacturer’s instructions and jump start safety guidelines. Improper connections or incompatible systems can cause damage or injury.
Can you jump start an electric car with another car?
Yes, some electric cars may be jump started with another vehicle if their 12-volt battery is dead, but many EVs recommend using a charger or professional service instead.
What if the electric car’s 12-volt battery is weak?
A weak 12-volt battery in an electric car may not have enough power for jump starting another car. Consider charging or replacing it first.
Are there alternatives to jump starting with an electric car?
Alternatives include portable battery jump starters, roadside assistance, or using a hybrid or gasoline vehicle to jump start.
