Pure Electric Range refers to the maximum distance an electric vehicle can travel on a single charge. It is influenced by factors such as battery capacity, driving habits (e.g., rapid acceleration, high-speed driving), environmental temperature, vehicle load, and HVAC usage. Differences in testing standards (e.g., NEDC, WLTP) result in variations in rated range values, with real-world range often being lower than lab-tested data. Improving range can be achieved through battery technology optimization, reduced energy consumption, or the use of energy-efficient driving modes.
