This SAE Recommended Practice establishes uniform procedures for testing electric battery-powered vehicles which are capable of being operated on public and private roads, and is to replace the range and vehicle energy economy sections SAE J227a. The procedure addresses electric vehicles (EVs) only. It is the intent of this practice to provide standard tests which will allow for determination of energy consumption and range based on the Federal Emission Test Procedure (FTP) and the Highway Fuel Economy Test Procedure (HWFET). Realistic alternatives should be allowed for new technology. Performance is judged on the total vehicle system and the battery.
Dynamometer test procedures are specified in this document in order to minimize the test-to-test variations inherent with track testing and to adhere to standard industry practice for energy consumption and range testing.
Section 2 provides definitions of terminology used in this document. Section 3 specifies test conditions and general instrumentation which are to be used for tests specified in this document. Section 4 identifies the data which are to be recorded. Section 5 specifies standard driving cycles. The specific tests covered by this document are:
  1. a
    Vehicle Energy Consumption According to a Selected Driving Pattern (Section 6)
    1. (1)
      EPA Urban Driving Schedule (UDS)
    2. (2)
      Highway Fuel Economy Test Procedure (HWFET)
  2. b
    Vehicle Range When Operated According to Selected Driving Patterns (Section 7)
    1. (1)
      Combined EPA Urban Driving Schedule (UDS) and Highway Fuel Economy Test Procedure (HWFET)
  3. c
    Coastdown Testing (Section 8)
