5.2.1 General
5.2.1 常规

After the crash test at least one of the criteria specified in 5.2.2 through 5.2.5 shall be met for each voltage class B electric circuit. This includes all voltage class B electric circuits which are disconnected or electrically separated by an automatic disconnect function or device(s) in post-crash situations. For different parts of a circuit, different criteria specified in 5.2.2 through 5.2.5 may apply.
碰撞试验后，对于交流h 电压 B 类电路，应至少满足 5.2.2 至 5.2.5 中规定的标准之一。这包括所有电压等级 B 的电路，这些电路在碰撞后通过自动断开功能或设备进行断开或电气隔离。对于 circuit 的不同部分，可能适用 5.2.2 到 5.2.5 中指定的不同标准。

If it is agreed with the testing authority with valid reason, the test is can be performed under the condition that part(s) of the voltage class B electric circuits are not electrically energized because of specific crash test conditions different from normal operation. In this case, the protection against electric shock shall be proved by either 5.2.3 or 5.2.4 for the relevant part(s). Examples for such specific test conditions are as follows:
如果与测试机构达成一致并有正当理由， 则可以在电压 B 类电路的一部分由于与正常运行不同的特定碰撞测试条件而不通电的情况下进行测试。 在这种情况下，相关部件的防触电保护应由 5.2.3 或 5.2.4 证明。此类特定测试条件的示例如下：

— fuel cell vehicle crash test performed with alternative fuel;
— 使用替代燃料进行的燃料电池汽车碰撞测试;

— crash test performed with energy sources disconnected by activation of the automatic disconnection prior to the crash test.
— 在碰撞测试之前通过自动断开的激活断开能源的情况下进行碰撞测试。

NOTE1 Electronic switches can be used for disconnection.
注1 电子开关可用于断开连接。

Though coupling systems for charging the RESS is not energized when the test is performed, four criteria in 5.2.2 through 5.2.5 can be applied.
虽然在执行测试时，用于为 RESS 充电的耦合系统没有通电，但可以应用 5.2.2 到 5.2.5 中的四个标准。

NOTE2 As the coupling system for charging is end up being energized and having high voltage in failure situations, 5.2.2 or 5.2.5 can also be applied as criteria.
注2由于充电耦合系统最终通电并在故障情况下具有高电压，因此 5.2.2 或 5.2.5 也可以作为标准应用。

5.2.2 Voltage limit Absence of high voltage
5.2.2电压限制没有高电压

The voltages V_b, V₁, and V₂ (see Figure 1) of the voltage class B electric circuits shall be equal to or less than 30 V AC (rms) or 60 V DC at a point in time t_m which is specified as
电压 B 类电路的电压 V_b、V₁ 和 V₂（见图 1）在时间点 t m 应等于或小于 30 V AC （rms） 或 60 V DC ，具体指定为

— either 10 s after the initial impact, if the vehicle comes to rest within 5 s after the initial impact, or
— 初始 IMP AC T 后 10 秒，如果车辆在初始 IMP AC T 后 5 秒内停止，或

— 5 s after the vehicle comes to rest, if the vehicle does not come to rest within 5 s after the initial impact any time between 10s and 60s after the impact and the passenger compartment meets the physical protection requirements as described in 5.2.4.
—车辆静止后 5 秒，如果车辆在初始撞击后 5 秒内没有停止，并且在撞击后 10 秒至 60 秒之间，乘客舱满足 5.2.4 中描述的物理保护要求。

NOTE "tm" is a probable time when a person can touch live parts after the impact. Therefore, a safe state needs to be achieved by tm. 10s is a time to prevent passengers in the cabin from getting electric shock. 60s is a time when first responders may access the damaged vehicle and start rescue work. Then, in the case that passenger safety is assured by physical protection, “tm” can be any time between 10s and 60s specified by the vehicle manufacturer
注意：“tm”是撞击后人可以触摸带电部件的可能时间。因此，需要通过 tm 来实现安全状态。10s 是防止机舱内乘客触电的时间。60 年代是急救人员可以接近受损车辆并开始救援工作的时候。然后，在通过物理保护确保乘客安全的情况下，“tm”可以是车辆制造商指定的 10 秒到 60 秒之间的任何时间.

Compliance shall be tested in accordance with 7.2.2.
合规性应根据 7.2.2 进行测试。

5.2.3 Isolation resistance
5.2.3 隔离电阻

5.2.3.1 General
5.2.3.1 常规

The isolation resistance shall fulfil the requirements according to 5.2.3.2 and 5.2.3.3.
隔离电阻应满足 5.2.3.2 和 5.2.3.3 的要求。

If direct contact to one potential of the voltage class B electric circuit is possible, the energy in Y-capacitors, TE_y, as calculated in 7.2.5.2.2 shall be less than 0,2 J.
如果可以直接连续到电压等级 B 电路的一个电位，则 7.2.5.2.2 中计算的 Y 电容交流电 TE_y 中的能量应小于 0,2 J。

注意：Y 型电容交流电阻引起的潜在体电流不受隔离电阻的限制。

The isolation resistance criterion shall not apply if direct contact to more than one single potential of a part of the voltage class B electric circuit is possible; see 5.2.4 (physical protection). However, isolation resistance criterion is applicable if the voltage difference between those accessible live parts meets the voltage limit specified in 5.2.2 or the potential energy between them meets the energy limit specified in 5.2.5.
如果可以直接接触 B 类电压电路的一部分的多个单个电位，则隔离电阻标准不适用;参见 5.2.4（物理保护）。 但是，如果这些交流可触及的带电部件之间的电压差满足 5.2.2 中规定的电压限制，或者它们之间的势能满足 5.2.5 中规定的能量限制，则适用隔离电阻标准。

Compliance shall be tested in accordance with 7.2.3.
合规性应根据 7.2.3 进行测试。

If test procedures include a static rollover test after a crash, evaluation of isolation resistance can be conducted before, during, and/or after the rollover test.

Energy Safety Limit Derivation
能源安全限制推导

General
常规

This appendix describes the derivation of energy limit of capacitor discharge for electric shock protection (Energy Safety Limit), as a function of voltage, from the limits given in IEC 60479-1 (2018) and -2 (2017)
本附录描述了用于电击保护的电容器放电能量限制（能源安全限制）作为电压的函数，从 IEC 60479-1 （2018） 和 -2 （2017） 中给出的限制得出.

When assessing the electric shock risks by capacitive discharges, both the body current and its duration determine the risk to a human. Specifically, discharge pulses less than 10 ms in duration utilize the threshold given in Figure 20 of IEC TS 60479-2, while discharge pulses longer than 10 ms utilize the threshold given in Figure 22 of IEC TS 60479-1
在评估电容放电的触电风险时 ，体电流及其持续时间都决定了对人类的风险。具体来说，持续时间小于 10 ms 的放电脉冲使用 IEC TS 60479-2 图 20 中给出的阈值，而持续时间超过 10 ms 的放电脉冲使用 IEC TS 60479-1 图 22 中给出的阈值

Those two figures in IEC60479-1/-2 are combined into Figure X. The area more than 10ms in duration is separated into four zones (from DC-1 to DC-4) with three boundaries, while only boundary of DC-4 zone (c1 line) with no separation from DC-1 to DC-3 zones is specified in the area less than 10ms.
IEC60479-1/-2 中的这两个数字组合成图 X。 持续时间超过 10ms 的区域被分成具有三个边界的 f 个区域（从 DC-1 到 DC-4），而在 小于 4ms 的区域内仅指定从 DC-1 到 DC-3 区域没有间隔 的 DC-1 区域（c1 线）的边界。

For capacitor discharge, the effects on human body are evaluated by calculating the root-mean-square values (rms) of body current and identifying the zones they are plotted
对于电容器放电，通过计算体电流的均方根值 （rms） 并确定它们所绘制的区域来评估对人体的影响.

Historically, 0.2J has been used as safe energy threshold in international and national standards and regulations. It is derived from b-line, the boundary between DC-2 and DC-3 zone. The b-line means the upper limit of DC-2 zone which is defined “usually no harmful”. It is appropriate to continue using 0.2J as the threshold in the region of 10 ms or more in duration
从历史上看，0.2J 在国际和国家标准和法规中一直被用作安全能源阈值。它源自 b-line，即 DC-2 和 DC-3 区之间的边界。b线表示定义为“通常无害”的DC-2区的上限，在持续时间为10毫秒或更长时间的范围内继续使用0.2J作为阈值是合适的.

In the area below 10 ms in duration, as b-line does not exist, using c1-line is the only option for making threshold. The c1-line means the upper limit of DC-3 zone which is defined “usually no organic damage” and “0% of probability of ventricular fibrillation”. Connecting between point A and B1 with d-line is one way. The problem is discontinuity in the energy value between points B1 and B2. To address this, connecting point A and B2 with d-line is applied as a threshold. This method aligns with ​​a boundary making concept in SAE J1772
在持续时间低于 10 ms 的区域，由于 b 线不存在，因此使用 c1-line 是创建阈值的唯一选项。c1 线表示 DC-3 区的上限，定义为“通常无器质性损伤”和“心室颤动概率的 0%”。用 d 线连接 A 点和 B1 点是单向的。问题是点 B1 和 B2 之间的能量值不连续。为了解决这个问题，将带有 d 线的连接点 A 和 B2 作为阈值应用。该方法与 SAE J1772 中的边界制定概念一致.

Although d-line does not mean a constant effect on human body, it is considered to be appropriate in a sense that it continuously connects the end of b-line (point A) and c1-line
虽然 d 线并不意味着对人体的持续影响，但从某种意义上说，它被认为是合适的，因为它连续连接 b 线的末端（A 点）和 c1 线.

For capacitor discharge, the following equations are valid and utilized in IEC60479-2 and SAE J1772. These equations are also used in derivation procedures in A.2 of this appendix.
对于电容器放电，以下公式s 有效 ，并在 IEC60479-2 和 SAE J1772 中使用。 这些方程s 也用于本附录 A.2 中的推导程序。

The range where body current duration is more than 10ms
体电流 du比值大于 10ms 的范围

0.2J is used as an energy limit in the range more than 10 ms in duration. This value is widely utilized in international and national standards and regulations.
0.2J 用作持续时间超过 10 ms 的范围内的能量限制。 该值在国际和国家标准和法规中得到广泛应用。

The figure X plots the body current (Icrms) and its duration (ti) of 0.2 J capacitors with different voltages. The human body resistance is assumed 500 Ω.
图 X 绘制了不同电压下 0.2 J 电容器s 的体电流 （Icrms） 及其持续时间 （ti）假设人体电阻为 500 Ω。

Duration and Body current derived from 0.2J are in DC-2 zone which means “usually no harmful” in the range more than 10ms. However, no rationale for 0.2 J exists in the range less than 10ms in duration.
从 0.2J 得出的持续时间和体电流位于 DC-2 区，这意味着在超过 10ms 的范围内“通常无害”。但是，在持续时间小于 10 毫秒的范围内不存在 0.2 J 的基本原理。

Calculated capacitance values for 0.2J decline sharply when the capacitor voltage becomes high
当电容器电压变高时，0.2J 的计算电容值会急剧下降.
