2025年01月04日,为什么手机充电速度越来越快?5分钟充电50%,会影响电池寿命吗?原创2022-06-14 17:45·怪罗科普今年618开门红,手机行业的销量黑马无疑是真我手机,可能由于活动力度还比较大吧,真我GT系列全渠道一秒钟就突破1亿元销售额,其中2000元档手机天猫销量第一,2000-3000元档京东销量第二。可能很多人对这个手机品牌不是很熟悉,我查了下真我手机和oppo共享部分技术,不过该品牌初期主攻海外市场,进入国内才只有三年时间而已,定价基本在2000元-3000元左右。虽然,现在手机卖的是越来越便宜,但是手机的性能真的是越来强大,我看了下真我手机这次618的一个主推款——真我GT Neo3,这是一款游戏手机,有一个核心功能就是150W光速秒充, 5分钟充电50%。很多人都好奇过,手机卖得不贵,充电效率却这么快是否安全呢?快速充电又是否会影响电池的使用寿命呢?如何做到快充?其实,实现快充的原理是非常简单的,就是增大充电的功率,因为输入的功率变大了,充满相同电量的时间自然减短了。众所周知,功率和电压、电流、电阻有关系,它与电压、电流的大小成正比,和电阻的大小成反比。但是对于手机快充来说,再优化电阻是比较困难的,所以基本是通过加大电压或者电流来实现快充的,一般手机手机厂商的快充有两种方式——低电压大电流快充、高压快充。然而,给铝电池快充的话不可能保持恒定的大电流和电压,这是因为随着电池被充满,它释放的热量和本身的电压会上去,如果用恒定的电压或者电流去充电的话,可能会导致充电效率降低或者电池过热。实际上,现在快充手机的充电器都是有一个充电曲线,它会控制电压和电流,以实现最优的充电效率。这也是为什么手机厂商只会告诉你5分钟内充满50%,而不是10分钟内充满100%,因为随着电池被充满,基本不可能做到恒定电流或者恒定电压,都需要经过调整才行,后面的50%充电速度会大打折扣。图注:杨幂手里的是真我GT Neo3那么快充是否安全呢?我们以真我GT Neo3为例,这款手机售价在3000元左右(配置不同价格有所变动,另外618至高减300元),它这个价位配置150W快充确实是性价比比较高的了,我对比了下几个品牌,这个价位的快充手机一般是120W。如果要加大功率来快速给铝电池充电的话,它对电源适配器、充电线、快充芯片,以及电池材料都有很高的要求,这些都是成本。比如,电池本身需要活性材料,同时隔膜和电解液还需要特殊的设计,这会提升材料和生产成本。另外,快充还有一个最大的问题,那就是电池局部过热,这个是最危险的,不过现在的手机厂商会使用石墨烯等一些新的散热材料,来保证安全性。真我GT Neo3用的就是金刚石冰心散热系统MAX,如果没有这些散热材料加持的话,根本无法实现快充。快充手机都包含有快充芯片,它可以监测电池的数据,及时做出充电调整,避免过热等情况发生。换句话说,如果手机电池是支持快充的话,那么安全性基本是有保障的,毕竟产商肯定是经过无数次测试之后才敢上市。但是,所有的快充都会影响电池寿命,这是快充的性质决定的!快充减短电池使用寿命由于现在锂电池的使用非常广泛,所以人们对它的测试数据还是比较多的,它有一个最明显的特征,就是铝电池的充电循环寿命跟充电倍率有关系。充电倍率就是充电快慢的量度,在合理的充电倍率下,铝电池的寿命会更长,很明显从“快充”的命名上都可以看出来,这种方式是不合理的充电倍率,所以它会减短电池使用寿命。不过,所有手机厂商都在努力尽可能地保护电池,降低损耗,比如我们前面提到的控制电压和电流,这也是保护电池的手段。另外,快充的占比越大,电池的损耗就会越大,目前手机的快充阶段最多会达到80%的电量。不过,现在消费者换手机的频率一般在2-3年左右就会换一个,所以即便快充会影响手机电池寿命,但其实也没有太大的影响。最后任何电池都有使用寿命,一般是按照能够多少次循环充满电来算的——是电量完全亏空到完全充满的次数。对于手机电池而言一般是600次这样的循环,快充的寿命可能比这个稍微短一点,但基本也在人们的换机频率之内吧。对于手机电池的使用寿命,有一个小诀窍,那就是尽可能不要等电量完全亏空时再充电,这样可以延长电池使用寿命的。
