How Are Car Batteries And Key Fobs Related?
We all know that feeling. You’re standing in the parking lot, fumbling through your purse or pockets for your car keys, and you realize they’re not there. You probably left them sitting on the kitchen counter or coffee table.
Now you’re stuck. But have you ever wondered why your car keys and your car’s battery are related? It’s not just because they’re both essential to your car’s operation. The reason has to do with the way car batteries are charged. Most car batteries are lead-acid batteries. Lead-acid batteries work by using a chemical reaction between lead and sulfuric acid to create an electrical current. This current is then used to power your car’s engine.
The lead-acid battery has two plates, one made of lead and one made of lead oxide. These plates are separated by a thin layer of electrolyte, which is a solution of water and sulfuric acid. When the battery is being charged, the lead oxide plate gives up some of its electrons to the lead plate.
This creates a flow of electrons between the two plates, which generates an electrical current. The electrons flow from the lead oxide plate to the lead plate because the lead oxide has a higher potential than the lead. The potential is like a water pressure difference – the higher the potential, the greater the flow. The lead-acid battery can only generate a small amount of current, so it needs a boost from an outside source to get started. That’s where your car key comes in.
When you put your key in the ignition and turn it, you’re actually completing a circuit between the battery and the starter motor. This sends a surge of current from the battery to the starter motor, which is what gets your engine going. So, next time you can’t find your car keys, just be thankful that you don’t have to jump-start your car battery. And if you do have to jump-start your car, you can thank your car key for helping out.
