What Does “Electric Car Jump Start” Mean?
The term “Electric Car Jump Start” might sound confusing at first, as we usually associate jump-starts with dead batteries in combustion engine cars. However, electric cars are not immune to power problems either.
Unlike gasoline or diesel vehicles, EVs don’t need a jump start to crank the engine. Instead, it’s about restoring power to the 12-volt battery, which is responsible for the onboard electronics.
Why Does an EV Need a Jump Start Anyway?
The 12-volt battery in your electric car powers essential systems such as lights, central locking, and, most importantly, the control electronics that enable the high-voltage battery to start. If this battery is dead, the vehicle cannot be started, even if the main drive battery is sufficiently charged.
Causes for a dead 12-volt battery can include:
- Extended vehicle downtime
- Extreme temperatures
- Defective electronic consumers
- Battery aging
How Does Jump Starting an Electric Car Work?
The good news is that jump-starting an electric car works in principle just like jump-starting a vehicle with a combustion engine. You will need:
- A jump start cable
- A donor vehicle with a functioning battery or a jump starter device
Important: Make sure that the jump start cable is suitable for use with electric cars!
Safety guidelines for jump starting an electric car, highlighting important precautions
Step-by-Step Instructions:
- Connect the red clamp of the jump start cable to the positive terminal (+) of the dead battery.
- Connect the other red clamp to the positive terminal (+) of the donor battery.
- Connect the black clamp of the jump start cable to the negative terminal (-) of the donor battery.
- Connect the other black clamp to a suitable ground point on the vehicle with the dead battery (e.g., the engine block).
- Start the donor vehicle and let it run for a few minutes.
- Now try to start the vehicle with the dead battery.
Caution: Be sure to observe the safety instructions in your vehicle’s operating manual! Incorrectly connecting the cables can cause damage to the electronics.
Advantages of Electric Car Jump Start:
- Quick and uncomplicated restoration of operational readiness
- Avoidance of towing costs
- Greater independence from workshops
Tips for the Future:
- Avoid letting your electric car stand idle for extended periods.
- Pay attention to the charge status of the 12-volt battery.
- Have defective electronic consumers repaired immediately.
- Perform regular battery maintenance.
Frequently Asked Questions about Electric Car Jump Start:
Can I jump start my electric car with a normal jump start cable?
No, it is strongly recommended to use a jump start cable specifically designed for electric cars. Normal cables may not offer the necessary protection against voltage spikes.
Can I also externally charge the 12-volt battery of my electric car?
Yes, the 12-volt battery can be charged with an external charger. However, make sure to use a charger that is suitable for your battery.
Conclusion:
Even if a dead battery is annoying, it can be easily remedied with the right approach and a little know-how. With our guide to electric car jump starts, you are prepared for emergencies and can quickly and safely get your electric car running again. If you are still unsure, do not hesitate to seek professional help.
