What to Do When an Electric Vehicle's Battery Runs Out of Power?

First, eliminate the most suspected battery issue. For a car that cannot start, check if the battery voltage is too low to power on or if the battery is damaged. Next, check whether the car's fuel gauge is below the warning line. If the car is out of fuel, it will also fail to start. Then, consider whether the driver's operation is the problem, leading to failure in one-button start. Improper operation occurs more frequently for new cars or novice drivers. Finally, consider whether the driver has any bad parking habits. For example, if the driver only engages the handbrake but forgets to shift the gear lever to the P position when parking.
I remember that time when my electric car's 12V auxiliary battery suddenly died, mainly because I left it parked for too long without driving, and the battery automatically discharged. When this happened, I immediately pulled over to a safe spot and turned on the hazard lights. Then, I found jumper cables and got a friend's car to help connect the positive and negative terminals for charging. After about ten minutes of charging, I tried starting the car, and it worked fine. Afterward, I even bought a portable jump starter to keep on hand—super convenient. For prevention, I recommend driving at least a short distance every week to let the system automatically charge the battery, especially in winter when cold temperatures make it easier for the battery to drain. It’s also good to regularly check the battery health—just use a multimeter to test the voltage and keep it above 12V. Don’t wait until there’s a problem to regret it.
