What is a Battery meter?

A battery meter is a device that displays the remaining battery power and charging status. Automotive and mobility battery meters are typically installed on dashboards or control panels to indicate battery status to drivers and users.
A battery meter measures parameters such as battery voltage, current, or capacity and uses them to display the battery's remaining power and state of charge. Typical displays are bar graphs or numbers that show the remaining amount as a percentage. Some vehicles may also indicate battery status with icons or lights.
