The world of electric vehicles has been rapidly evolving over the past decade, with many car manufacturers investing heavily in the development of eco-friendly and sustainable transportation options. As the demand for electric vehicles continues to grow, it’s essential to understand the basics of car batteries, including the voltage, capacity, and chemistry. In this article, we’ll delve into the world of car batteries and explore the various voltages used in electric vehicles.
Understanding Car Battery Voltage
When it comes to car batteries, voltage refers to the electrical potential difference between the positive and negative terminals of the battery. In other words, it’s the measure of the force that drives electric current through a circuit. Car batteries are designed to provide a specific voltage, which is measured in volts (V). The most common voltage ranges for car batteries are 12V, 24V, and 48V.
12V Car Batteries
The 12V car battery is the most widely used type of battery in the automotive industry. It’s designed to provide a nominal voltage of 12.6V, with a range of 12.4V to 12.8V. 12V batteries are commonly used in gasoline-powered vehicles, as well as hybrid and electric vehicles. They’re also used in many other applications, such as motorcycles, boats, and recreational vehicles.
