rapidly for several years.

The background of the new regulations establishment

• 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.
