随着全社会用电量的增加，新能源的快速发展，包括电动汽车，储能等新兴产业的兴起，带来了储能器件的市场需求越来越大。由于锂电池具有高储存能量密度；使用寿命长；具备高功率承受力；自放电率很低；重量轻；高低温适应性强；不论生产、使用和报废，都不含有、也不产生任何铅、汞、镉等有毒有害重金属元素和物质，绿色环保等优点，成为目前储能方式的。

由于市场对锂电池的期望值越来越高，好的制造工艺和技术成为保障锂电池性能优势的关键。电池化成、分容作为锂电池生产过程中必不可少的工序，对锂电池性能的优劣起着至关重要的作用，化成的好坏，直接影响到锂电池效率，循环使用寿命，热稳定性和安全性能。

一般来说，电池化成的工艺分为恒流充电、恒压充电和恒功率充电，恒流放电、恒功率放电和恒阻放电阶段,电池化成过程对锂电池的充放电电流电压测量的误差要求较高，比较理想的精度是万分之五到万分之一，以便保证化成设备的总体精度在千分之一。那么合适的测量手段也是化成设备的重要指标，常用的分流器测量，虽然精度可以满足要求，但由于共模电压高，在化成设备中无法使用。一般的电流传感器精度好的可以达到0.2%，但很难满足整个测量范围内高精度等级的要求，再加上化成过程中对温度的要求，低温漂也是必备的条件。

LEM作为电量测量解决方案的专家，在原有高精度传感器的基础上，为电池化成量身定制的高精度IT/IN系列电流传感器，采用闭环磁通门技术，在化成设备的交直流侧可以通用。通常化成设备交流侧用3只传感器，直流侧用2只传感器。
