前言： 技术引见 蓄电池中由于电解液不纯、电解液中硫酸浓度不均形成极板产生电位差，长期运用后极板孔隙梗塞招致内阻耗费增大等
蓄电池中由于电解液不纯、电解液中硫酸浓度不均形成极板产生电位差，长期运用后极板孔隙梗塞招致内阻耗费增大等，都会致使铅酸蓄电池在无外接负载时呈现自放电现象，自放电现象会极大影响蓄电池的循环运用性能及寿命，传统的应对方式之一是定期对蓄电池停止补电，补电需人工操作，补电量不易控制，补电周期及时长难以肯定，易形成补电缺乏或过充，且没有思索到蓄电池个体及环境差别，因而寻觅一种能对铅酸蓄电池补电停止智能控制的处理计划显得尤为重要。因此现有技术还有待改良和进步。
蓄电池的补电办法和系统。其中，所述办法经过对对蓄电池停止周期性补电，蓄电池在休眠时间段休眠，在补电时间段内补电；依据从休眠状态转为补电状态时的蓄电池组电压的变化趋向，判别补电能否充足；在补电缺乏时，持续在M个补电周期中延长补电时间段和/或缩短休眠时间段，当M个补电周期完毕后，重新判别补电能否充足；在补电充足时，持续在N个补电周期中缩短补电时间段和/或延长补电周期的休眠时间段，当N个补电周期完毕后，重新判别补电能否充足。经过检测到的蓄电池组电压的变化趋向动态肯定补电时长，防止补电缺乏或过充，进步了蓄电池补电的性，提升了蓄电池的运用寿命。
The invention discloses a battery charging method and system. Among them, the method by periodically fill power of the battery, the battery in the dormant period of dormancy, fill power in the fill power period; according to the change trend from a dormant state to the voltage of the battery pack up electricity when the fill power is sufficient in the judgment; fill power is insufficient, prolonged repair electric time and / or shorten the sleep time period in M fill power cycle, when M fill power after the end of the cycle, to determine the adequacy of the fill power; in the fill power is sufficient, in a continuous N fill power cycle shortened up power time and / or prolonged dormancy time fill power cycle when N, a fill power after the end of the cycle, to determine the adequacy of power compensation. By detecting the change tendency of the battery voltage, the time of power supply is dynamically determined, and the power shortage or overcharge is avoided, the accuracy of the battery charging is improved, and the service life of the accumulator is improved.
