EV Jump-Start & 12V Battery Service
Every electric car still has a small 12V battery that powers the computers, door handles and contactors. When it dies, a car with a full main battery can look completely dead. A safe 12V boost usually brings it back in minutes.
Overview

When to call

EV Jump-Start (12V Battery) FAQ
If your situation is urgent, call dispatch now.
Can I jump-start an EV with another car?
Some manufacturers allow it and others warn against using an EV to jump another car. A portable jump pack connected to the correct terminals is the safest approach.
Will a jump-start charge the main battery?
No. A 12V boost wakes the car up. If the main battery is also low, choose the jump-start and charging combination.
