- While it is possible to jump the 12-volt battery in an electric vehicle, never try to jump start its high-voltage lithium-ion batteries.
- Do not use an electric vehicle (EV) to power another 12-volt battery. “Electric vehicle charging points are for starting the car itself and not for assisting another vehicle with a jump startHardesty writes.
- The vehicle that gives the electric vehicle a jump start must have a 12-volt battery with a negative ground system, which, Hardesty says, it is typical of cars that run on gasoline.
- The instructions below provide an overview of how to jump-start electric vehicle batteries, but make sure you consult the manufacturer’s manual firstin case that particular make/model need special treatment.

In his article, Hardesty provides the following instructions for jump-starting a dead 12-volt battery in an electric vehicle:
- Get the cars ready. Place the two vehicles, the EV and the vehicle with a good battery, close to each other so they don’t touch.
- turn on the brake. Change to parking lot and put the parking brake.
- Turn everything off. Check and make sure you turn off the lights and accessories on both vehicles.
- Connect the positive clamps. You are now ready to connect one end of the red positive (+) cable to the positive (+) terminal of the discharged battery. When you’re done, connect the other end of the positive (+) jumper cable to the positive (+) terminal of the vehicle’s booster battery.
- Place negative clamps. Next, place one end of the black negative (-) cable on the negative (-) terminal of the good battery. Now connect the negative (-) jumper cable to the negative (-) grounding point of the discharged battery.
- Check. Make sure the booster cables are away from any moving parts and that the clamps have good metal-to-metal contact with the battery terminals and charging points.
- Start the car of the donation vehicle. Take the vehicle with the good battery and start the car.
- Turn on the EV. Finally, he tries to start the vehicle with the dead battery.
