Proposal to amend para. 3.3.2. to insert structured subsections for REESS trade name, cell types, physical dimensions, description, electrical specifications, gas combination rate, installation description, thermal management and electronic control, insert new paras. 4. to 9.1. requiring information on fuel cell specifications, fuses and circuit breakers, power wiring harness, protection against electric shock, power circuit component details, and hydrogen system components located in the energy absorption zone. These modifications address insufficiently defined topics on REESS type, electrical system and hydrogen system in vehicles by introducing relevant sections from UN R100 and adding hydrogen system documentation requirements.
