<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">汽车早<span style="color: black;">已然</span><span style="color: black;">走进</span>千家万户，<span style="color: black;">各样</span>车载科技<span style="color: black;">亦</span>就随之蓬勃发展。高清行车记录仪、流<span style="color: black;">媒介</span>后视镜、倒车影像、LED日行灯、胎压监测等等<span style="color: black;">非常多</span>智能化的科技设备，<span style="color: black;">能够</span><span style="color: black;">帮忙</span>广大车主们<span style="color: black;">增多</span>行车安全。<span style="color: black;">然则</span>，<span style="color: black;">大众</span>有<span style="color: black;">无</span><span style="color: black;">发掘</span>，这些后装的科技设备有部分<span style="color: black;">能够</span>用保险取电，但<span style="color: black;">亦</span>还<span style="color: black;">非常多</span>需要用到点烟器取电。<span style="color: black;">况且</span>，<span style="color: black;">咱们</span>还有一个重要的设备“手机”<span style="color: black;">亦</span>需要点烟器来充电。感觉<span style="color: black;">咱们</span>的点烟器有点<span style="color: black;">不足</span>用啊。于是，<span style="color: black;">各样</span>五花八门的点烟器都随之出来了，但<span style="color: black;">咱们</span>千万别乱用。</p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">不可</span>乱用的<span style="color: black;">原由</span>：峰值电流过大</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>每一辆汽车在设计时，都会<span style="color: black;">根据</span>配备的电瓶进行电气规划。对每一项可能用电都会做一个峰值电流设计。<span style="color: black;">倘若</span>超过这个峰值电流，为了<span style="color: black;">守护</span>汽车安全，保险丝会烧断。如何来判断<span style="color: black;">咱们</span>有<span style="color: black;">无</span>超过设计电流呢？<span style="color: black;">咱们</span>在买车的时候，4S店交付时都给了一本车书，<span style="color: black;">通常</span>车书上有。下面我附上一张样例图：</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/1cb383bdb46149f7bf0885ab7efe26e5~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1724962260&x-signature=PW477IoMK2KrT4aS8BopQ9sLtg8%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从上图，<span style="color: black;">咱们</span><span style="color: black;">能够</span>看到：车上两个点烟器+BCM<span style="color: black;">掌控</span>单元 <span style="color: black;">一块</span>最高为20A的最大电流。扣除BCM<span style="color: black;">掌控</span>单元的消耗电流，<span style="color: black;">便是</span>点烟器的电流了。<span style="color: black;">因为</span>BCM<span style="color: black;">掌控</span>单元是原厂的嵌入式电路，<span style="color: black;">没法</span>得知消耗电流，<span style="color: black;">咱们</span>还是<span style="color: black;">小心</span><span style="color: black;">运用</span>大功率的点烟器。否则，<span style="color: black;">导致</span>点烟器过载，就会烧毁保险丝。以下是几种<span style="color: black;">导致</span>电流过大的情形。</p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">电流过载的<span style="color: black;">状况</span>①：劣质车充</h1>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/dfic-imagehandler/0afca492-c18a-4e7c-8d2c-d270db49b286~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1724962260&x-signature=56XFGYSmcCWT0i3nkoQEe68F12Y%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">车载电池的默认电压是12V的，车充会进行降压到5V，<span style="color: black;">因此</span>车充<span style="color: black;">这儿</span>是有<span style="color: black;">掌控</span>芯片的。<span style="color: black;">掌控</span>芯片劣质的，不加以<span style="color: black;">掌控</span>，很可能<span style="color: black;">导致</span>电流过大。<span style="color: black;">因此</span>，购买车充时要<span style="color: black;">重视</span>，<span style="color: black;">尽可能</span>购买质量好一点的车充，<span style="color: black;">最少</span>带<span style="color: black;">守护</span>电路的。</p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">电流过载的<span style="color: black;">状况</span>②：高电流的输出<span style="color: black;">太多</span></h1>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/4ce62093e4064b6e86a789bbae1b6c2f~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1724962260&x-signature=vXtRYtr21N7XhD8vjmOYb%2F8hYXg%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">此刻</span>车载设备动不动都是5V，2A的了，<span style="color: black;">乃至</span>有些还更高。智能手机<span style="color: black;">此刻</span><span style="color: black;">亦</span>是电池越来越大，开车用手机来导航是再<span style="color: black;">广泛</span><span style="color: black;">不外</span>的了，但导航手机耗电<span style="color: black;">火速</span>，<span style="color: black;">因此</span>，需要<span style="color: black;">始终</span>插着车充。这<span style="color: black;">亦</span>就<span style="color: black;">需求</span>车充<span style="color: black;">最少</span>都是5V，2A的USB接口。<span style="color: black;">然则</span>，就算是5V，2A的接口<span style="color: black;">针对</span><span style="color: black;">此刻</span>大容量手机电池，充电速度<span style="color: black;">显出</span>有点过慢。<span style="color: black;">非常多</span>司机还想要配备<span style="color: black;">拥有</span> 超级快充 的车充。<span style="color: black;">这般</span>输出电流最大<span style="color: black;">能够</span>到 5A ，<span style="color: black;">这般</span>，手机充电速度才够快。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">虽然，<span style="color: black;">经过</span>配备超级快充的车充，<span style="color: black;">能够</span>达到<span style="color: black;">火速</span>充电的目的，<span style="color: black;">然则</span>，<span style="color: black;">必定</span>要记住，你的电流加大了，<span style="color: black;">亦</span>就加大了汽车电池的<span style="color: black;">包袱</span>，需要<span style="color: black;">重视</span>你的总电流了。在车辆<span style="color: black;">长期</span>不开时，车辆<span style="color: black;">起步</span>时，会需要很大电流，这个时候，你的超级快充，最好先不要插上手机，等车子<span style="color: black;">起步</span>后再插。</p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">电流过载的<span style="color: black;">状况</span>③：漏电<span style="color: black;">或</span>短路</h1>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/9c1f5595e08e430db1afa2938c7e329d~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1724962260&x-signature=a%2BYErfQ3dFhpcgfOG8%2FHKVe%2B7Q4%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">用点烟器取电接<span style="color: black;">各样</span>外接电器时，<span style="color: black;">必定</span>要<span style="color: black;">重视</span><span style="color: black;">尽可能</span>不破线取电，不要<span style="color: black;">由于</span>接口<span style="color: black;">不足</span>就<span style="color: black;">自动</span>破线取电，时间长了，很容易<span style="color: black;">导致</span>漏电<span style="color: black;">或</span>短路。一旦<span style="color: black;">出现</span>这种<span style="color: black;">状况</span>，轻则损坏电池，重则<span style="color: black;">导致</span>汽车自燃<span style="color: black;">引起</span>车辆报废。</p>
