Some modern cars do not require a traditional 12-volt battery, particularly certain electric vehicles (EVs). Below are key points explaining this:

Electric Vehicles (EVs): Some do not rely on a 12-volt battery because they use high-voltage systems, typically 400V to 800V, to power the vehicle’s components.

High-Voltage Systems: In these EVs, the high-voltage battery pack powers all the vehicle’s electrical systems, including lights, infotainment, and other accessories, eliminating the need for a separate 12-volt battery.

Tesla Example: Tesla is transitioning away from the traditional 12V lead-acid battery in some of its latest models, opting instead for a 15V lithium-ion auxiliary battery that works in conjunction with the car’s high-voltage system.

Solid-State Battery Technology: Carmakers are developing new battery technologies, such as solid-state batteries, which may also eliminate the need for 12-volt systems, streamlining vehicle electrical architectures.

Simplified Design: Removing the 12-volt battery reduces the complexity and weight of the vehicle’s electrical system, making maintenance easier and increasing efficiency.

Future Trends: More manufacturers may eliminate the need for a 12-volt battery in future EV models as high-voltage systems become more advanced and capable of managing all vehicle functions.

In summary, while most vehicles still use a 12-volt battery for auxiliary functions, certain electric vehicles are beginning to abandon this and rely solely on higher-voltage systems.
