33、池的 容量和寿命,因此建立了快速充电方法的研究方向。这被称为曲线最好的充电模式原则。 马斯曲线初始充电电流很大,但很快减弱。其主要原因是它在充电过程中形成极化 现象。极化现象是指内部密封蓄电池产生的氧气和氢气在充电过程中,当氧气不能及时 吸收,然后堆积在正极板,扩大电池内部的压力,电池的温度上升,同时降低了正极板的 面积,提高性能的内部阻力。极化会影响充电的速度和质量,甚至减少蓄电池的寿命。因 此,开发很好的电池快速充电系统性能是非常重要的。在尽可能不影响蓄电池的使用寿 命的前提下,采用在短时间内最大充电电流,既电池不会产生过多气体,也不会使室内的 过程中体温过高。 3.太阳能路灯系统 在太阳能路灯系统中 , 蓄电池的充电源来自太阳能电池 ,气候的变化和用户的过度 用电非常容易造成蓄电池漏电,因此存在太阳能路灯正常工作的保证率低于交流电路灯 正常工作的情况。如果铅酸电池在使用过程中漏电, 3 4 5 6 7 8 9 10 浅议基于单片机的太阳能路灯的铅酸蓄电池的快速充电系统外文文献翻译 导读： 蓄电池的使用寿命将大大减少。如 果蓄电池在浮充电或浅放电条件下使用,那么蓄电池的使用寿命将会大大延长 ,甚至翻 倍。因此, 仅仅
