Electric vehicles (EVs) incorporate a 12-volt battery for specific functional advantages. The inclusion of this separate, smaller 12-volt battery serves several purposes in the design of EVs. Firstly, it contributes to maintaining the weight of the vehicle at an optimal level. By having a smaller auxiliary battery dedicated to non-propulsion functions, such as powering lights, audio systems, and other accessories, the overall weight of the vehicle is kept down. This weight management is crucial for the efficiency and performance of the EV.
Another key benefit of the 12-volt battery in EVs is its role in enhancing the vehicle’s overall efficiency. With a dedicated battery for auxiliary functions, the main high-voltage battery pack that powers the electric motor can remain focused solely on propulsion. This division of labor ensures that the high-voltage battery is not burdened with powering additional systems, allowing it to operate more efficiently. Consequently, the 12-volt battery helps in optimizing the energy usage of the EV, ultimately extending its range and enhancing its performance.
In essence, the incorporation of a 12-volt battery in electric vehicles is a strategic design choice aimed at weight management and operational efficiency. This auxiliary battery handles non-propulsion functions, reducing the load on the main high-voltage battery. By doing so, it contributes to keeping the vehicle’s weight down and improving its overall energy efficiency, which are crucial factors in the performance and range of EVs.
