<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><span style="margin: 0px; padding: 0px; border: 0px; color: rgb(89, 89, 89); font-size: 16px;">可以很肯定的说，纯电动汽车是怕水的。</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><span style="margin: 0px; padding: 0px; border: 0px; color: rgb(89, 89, 89); font-size: 16px;">纯电动汽车现在普遍采用的是将电池包安装在地板上的方式，在路面积水较深时电池组可能会被淹没，因为纯电动汽车电路系统复杂，如果电路系统漏电会很危险。</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><img src="https://www.autoju.com/wp-content/uploads/2019/06/30741561189888.jpg" style="margin: 0px; padding: 0px; border: 0px; max-width: 100%;"/></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><span style="margin: 0px; padding: 0px; border: 0px; color: rgb(89, 89, 89); font-size: 16px;">为了解决这一问题，国标委于2015年5月15日推出了GB/T 31485-2015《电动汽车用动力蓄电池安全要求及试验方法》，指出需要进行“海水浸泡”测试。</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);"><br/></p>

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><span style="margin: 0px; padding: 0px; border: 0px; color: rgb(89, 89, 89); font-size: 16px;">所以大家不要以为这项检测方法比一般情况更严苛，其实这么做只是为了保证实验安全。换个角度看，在实验室没发生爆炸，反倒实际情况下有可能爆炸。</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><img src="https://www.autoju.com/wp-content/uploads/2019/06/32491561189889.jpg" style="margin: 0px; padding: 0px; border: 0px; max-width: 100%;"/></p>

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><span style="margin: 0px; padding: 0px; border: 0px; color: rgb(89, 89, 89); font-size: 16px;">为此，一些城市会出台自己的约束标准，并作为纯电动汽车准入政策的强制性标准。这其中以上海最为出名，他们出台了DB31T634-2012标准，并且是直接针对整车进行检查。</span></p>
<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><span style="margin: 0px; padding: 0px; border: 0px; color: rgb(89, 89, 89); font-size: 16px;">准确来说，DB31T634-2012参考的是GB/T 18384.3-2001，但条件更加苛刻，特别是涉水总时间这一项GB/T 18384.3-2001的要求太蜻蜓点水了。</span></p>

<p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; border: 0px; max-width: 100%; color: rgb(42, 42, 42); font-family: &quot;Microsoft YaHei&quot;, &quot;Helvetica Neue&quot;, &quot;Hiragino Sans GB&quot;, Arial, sans-serif; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255); text-align: justify; line-height: 2em;"><span style="margin: 0px; padding: 0px; border: 0px; color: rgb(89, 89, 89); font-size: 16px;">IP67怎么理解呢？这里的数字6和7分别是防尘等级评判和防水等级评判。防水等级意味着它满足“短时浸水试验”要求，也就是电池浸入规定压力的水中经规定时间后外壳进水量不达致有害程度。</span></p>
