What is the difference between WLTP and EPA range?
1 Answers
EPA range is approximately 300 miles (about 482 kilometers), while the maximum WLTP range is 590 kilometers. Here is relevant information: 1. WLTP test cycle standard: This is the latest standard promoted by the United Nations, and Europe has been using this test cycle standard since September 1, 2018. This testing method first classifies vehicles into three levels based on the ratio of vehicle power to vehicle mass: less than or equal to 22, 22~34, and greater than or equal to 34. The test includes four driving cycles: low speed, medium speed, high speed, and ultra-high speed, with a total duration of 1750 seconds and a maximum speed requirement of 135 km/h. 2. EPA test cycle standard: This is a U.S. testing standard, and its most notable feature is the separate testing of electric and hybrid modes. That is, the vehicle is first fully charged to test the pure electric range, and then tested for the hybrid mode range when the battery is depleted. The test standard includes one urban cycle and two supplemental cycles. The urban cycle covers cold start transition, steady-state, hot soak, and hot start transition conditions, with a test duration of 1877 seconds and an average speed of 34.12 km/h.
