CAR BATTERIES Meaning and
Definition
-
Car batteries are electrical storage devices designed specifically to provide the necessary power to start an automobile's engine and operate its electrical systems. They are a type of rechargeable battery, also known as an automotive battery, that stores electrical energy, converting it into the high current required to start the engine.
Car batteries are typically made of six galvanic cells connected in series, forming a 12-volt system. These cells consist of lead plates that alternate between being coated with lead dioxide (positive plates) and spongy lead (negative plates). The plates are immersed in an electrolyte solution composed of sulfuric acid and water. When the battery is connected to a car's electrical system, the chemical reactions between the lead plates and the electrolyte create an electrical current.
Car batteries come in various sizes and capacities, with the most common being 12 volts, which is suitable for most standard passenger vehicles. However, commercial vehicles and certain high-performance automobiles may require higher voltage batteries. Car batteries can be recharged using the vehicle's alternator, which generates electricity while the engine is running, or with the help of an external charger.
In addition to providing the necessary electrical power to start an engine, car batteries also supply electricity to operate the lighting, radio, air conditioning, and other electrical components of a vehicle when the engine is not running. Thus, car batteries play a crucial role in ensuring the smooth functioning of an automobile's electrical systems and overall vehicle operation.
Etymology of CAR BATTERIES
The term "car batteries" derives from the combination of two words: "car" and "batteries".
The word "car" is a shortened form of "automobile", which originated from the Greek words "autos" meaning "self" and "mobilis" meaning "movable". The term "automobile" was first used in the late 19th century to refer to self-propelled vehicles.
The word "battery" has its roots in the late 16th century and comes from the French word "batterie" or "battre" meaning "to beat" or "to strike". It originally referred to a set of weapons or artillery to be used in battle. In the context of car batteries, the term evolved to describe a device that provides electrical power to a vehicle.
Therefore, "car batteries" refers to the power source used in automotive vehicles.
