Task Force 6 – state of charge:
Dr. Kawai, as the leader of TF6, provided a status report of the task force. He expects to conclude TF6 task team activity at its next face to face meeting expected in early next year if agreement is reached for the actual text proposal for SOC setup test protocol.
The US participant questioned how 50% range of SOC was decided. He also recommended to use a more technically correct wording to explain the SOC. US will join the discussion of TF6 and provide data from the US research.
OICA answered that the manufacturers can show the vehicle SOC operating range and its limit, and it helps being accountable and fair. It varies by a REESS type and manufacturer and it is very difficult to define one single number, test protocol, type of vehicle for the time being.
During the last face-to-face meeting, the TF6 leader drafted a new proposal for SOC. TF and IG members are invited to provide their comments on this proposal by the end of December 2015.
The EVS IWG asked TF6 to prepare a proposal for the draft GTR by next EVS meeting in 2015.
