Subgroup EV: Progress Report by EV Chairs (N. Mizushima, P. Ohlund), (WLTP-15-07e)

• Mizushima-san presents the progress report on EV.
• Normalization for EVs is still under progress, but need to find the possible solution due to technical difficulty for OVC-HEV and PEV.
• Durability: technical difficulties of a procedure to determine REESS durability – study until GRPE January 2017.
  • Mike Olechiw (US EPA): EVE will propose durability requirements. He expresses the need for a definition of requirements for different powertrain architectures (e.g. CO2, criteria pollutants, battery stability). The durability task force will give the requirements for WLTP on the durability criteria (mileage, …) These requirements will be sent to the EVE group.
  • EU-COM asks if a representative scheme for all types of batteries would be possible and if there are problems with different battery technologies?
  • While EVE focuses on the durability of a single battery, WLTP needs a method to define the durability of a whole (EV) vehicle. → to be changed in the terms of reference! → develop an appropriate battery test to represent an aged vehicle in the field.
