模拟暴雨、清洗及涉水要求

整车碰撞后安全要求 GB/T 31498-2015

防电击保护 Requirements for Safety Assurance:For each separate circuit, at least one of four options shall be met.Auto-manufacturer have to declare which option to use.

绝缘电阻Isolation resistance =》绝缘电阻+避免直接接触保护

Concept:If the body current when a person touches high voltage bus is sufficiently low, the circuit is not harmful.

人体保护Physical protection =》物理保护(避免直接接触和间接接触)

Concept:If direct contact protection and indirect protection is maintained after crash, the circuit is no harmful.

安全电压Low voltage =》降低高电压直流<=60V 交流<=30V

Concept:If the voltages are sufficiently low, the circuit is not harmful.

低电能Low energy =》低能量<= 2.0J

Concept:Even if the voltages are higher than 60VDC or 30VAC, the circuit is not harmful when the stored energy is sufficiently low.

电解液的泄漏要求

无可见电解液进入乘客舱

乘客舱之外的泄漏电解液<=7%和<=5L

电池要求

车载能源应保持在安装位置

车载能源任何部件应保持在边界内

碰撞中和碰撞后不能有车载能源的任何部件进入乘客舱

REESS系统在一定时间内不得起火、爆炸

2)国外现有的标准

ISO 6469-1:2009 Electrically propelled road vehicles -- Safety specifications-- Part 1: On-board regeable energy storage system (RESS)

ISO 6469-2:2009 Electrically propelled road vehicles -- Safety specifications-- Part 2: Vehicle operational safety means and protection against failures

ISO 6469-3:2011 Electric road vehicles -- Safety specifications -- Part 3:Protection of persons against electric hazards

ISO 6469-4 Proposal:Electrically propelled road vehicles — Safety specifications—Part 4: Post crash requirements

EN1987-1-2-3 Same as ISO6469-1-2-3

ECE R100 Uniform provisions concerning the approval of vehicles with regard to specific requirements for the electric power train

ECE R12/94/95 传统汽车转向机构、前碰、后碰法规补充了电动汽车的相关内容
