Description

充电器测试系统 技术领域
本发明属于电子测试领域，尤其涉及一种充电器测试系统。
背景技术
随着电子产品的发展，小型电池的应用越来越广，特别是近些年发展火热的无人飞行器，使得锂电池的应用相当广泛，同时也催生了充电器行业的发展。
一款好的充电器既要实现充电的速度，又要保证充电的精度。特别是精度控制上，难度较大。以现有的电子产品性能，提供参考电压的稳压电源IC(LDO)其电压误差及一致性均无法保证，市面上常见的LDO，其精度通常在±2％左右，以5V电源为例：其检测误差范围就高达5*±2％＝±0.1V，这样的误差对锂电池而言，是不可接受的。一般的锂电池充电器要求其误差范围不得超过±0.05V。上述计算只是考虑了LDO的误差，若再加上检测电阻等其它误差，其偏差之大可想而知。
因为充电器充电原理的特殊性，电池插上后，往往需要一个电池检测过程，判断电池是否损坏、是否需要预充等，这些过程需要几秒钟的时间，鉴于此，采用真电池测试充电器的性能，效率太过于低下，难于满足大批量生产的时效性需求。
因此如何检测及调校充电器的电压偏差，是生产过程的难题，也是必须要解决的问题。
