We hear you, short-circuiting can be really scary. Typically too much electricity isn’t what causes a short circuit. It’s often rodents, water, or chafing wires that cause it.
Overcharging an EV battery does harm over time but it wears down the battery as opposed to shorting it out. Both electric cars and traditional fuel cars are at risk of shorting out. When your vehicle’s electric systems are disrupted it causes a disruption in the flow of electricity and often routes it elsewhere it shouldn’t go. While it may be difficult to tell if this is what’s happening there are some symptoms to look out for.
  • Engine isn’t working normally. Your engine needs electricity to start properly so if its not or if there is a slow start it may be a shorted fuse.
  • Battery problems. If your battery isn’t functioning the way it normally would, like starting the car or helping other features work, it could be a dead battery or potentially a shorted fuse.
  • Lights don’t work If your headlights and or other lights have stopped working, it may be a short circuit issue.
  • Smell of burning plastic. If you smell anything burning as you drive your vehicle that could be a dangerous sign something is wrong. If you are experiencing other signs in addition to this, stop driving immediately.
Driving with a short circuit can be dangerous but there are ways to protect you and your vehicle. Make sure to do regular oil changes and checkups at the mechanic and if you suspect something is wrong call a professional and book an appointment.
