Its electrical energy is usually provided by an on-board battery (such as a lithium battery). The concept of electric vehicles covers a variety of types, including pure electric vehicles, hybrid vehicles, fuel cell vehicles, etc.; an electric vehicle instrument refers to an information system installed on an electric vehicle to display the vehicle status, driving information, and provide driving assistance functions.
