技术领域
本申请涉及电池技术，例如涉及一种多端口储能电池。
背景技术
近年来随着新能源的发展，光伏系统越来越多的进入家庭户用场景中，尤其是光照好的地区，光伏发电给人们带来了实实在在的好处。
白天光伏可以发电，但当太阳落山后光伏就无法继续发电使用太阳能了。随着锂电池的发展，使得这一问题得到解决，户用电池系统即户用电池包可以配合光伏系统，在白天通过给电池充电把太阳能储存至电池包中，而当夜晚时再把电池包的电释放出来给用户家庭使用。
这种方案固然可以解决太阳能储存的问题，但是由于电池所配合的光伏DC(Direct Current)-AC(Alternating Current)转换器有很多品牌和型号，投入使用较早的光伏DC-AC转换器没有电池接口，或者电池接口的电压等级不一致，比如有的是400V，有的是48V等等。这就带来很多问题，一旦用户选用了某种光伏DC-AC转换器，当希望进行储能方案对接时，可选的电池方案较少，相关的电池扩容性、替代性差，使得用户对于太阳能的投资收益下降，用户的体验受到影响。
