Regulations for HEVs HEVs and and Regulations for EVs on the Electric Safety on the Electric Safety EVs MLIT, Japan MLIT, Japan

The background of the new regulations establishment ● In Japanese market, the number of HEVs and EVs is increasing rapidly for several years. The number of H HE EVs Vs and and EVs EVs in 97 in 97 ’ -05 05 ’ The number of ’ - （ Number of Vehicles) ’ 300,000 HEV HEV 250,000 200,000 150,000 100,000 50,000 EV EV 0 2005 （ 1997 1998 1999 2000 2001 2002 2003 2004 （ FY ） FY ） 3,696 22,450 37,380 50,400 74,600 91,200 132,500 196,800 256,600 HEV EV 2,500 2,400 2,600 3,800 4,700 5,600 7,700 8,500 9,900

● Since the electric safety regulation of FCVs is already established in Japan, establishment of that of HEVs-EVs is pressing need. ● Although ECE-R100 is existing, it is difficult to introduce it into the Japanese regulations with the following reasons. -The scope of ECE-R100 is limited to Battery EVs． -The technical range of ECE-R100 does not correspond to the current new technology.

● As we have announced in the previous GRSP meeting, we are planning to establish the new safety regulation on the Electric Safety and Crash Safety for HEVs and EVs. ● The new safety regulation on the Electric Safety will be created based on ECE-R100. ● The new Electric Safety regulation leads to the ECE-R100 amendment which we will propose from now on.

The Outline of the Electric Safety Regulation (based on the ECE-R100) about HEVs and EVs ● Protection against electric shock at usually usage - Protection against direct contacts with live part. ex. Barrier, enclosure, etc. - Protection against indirect contact. ex. Electrical connection between exposed conductive parts (barrier, enclosure, etc.) and electrical chassis (vehicle flame, etc.) to prevent outbreak of high voltage - Insulation resistance. ex. Keep not less than 100Ω/V of the nominal voltage between live parts and electrical chassis. ● System Safety Requirement ex. The safety of the operation method and the charge state.
