Upsite Technologies由Uptime Institute2001年发布了一套整体式密封组件，至今已设计研发、生产了多项备受赞誉的专利解决方案。

　　UpsiteTechnologies提供机房内整套的气流管理、优化的产品和服务：包含KoldLok高架地板封堵组件、HotLok机柜气流管理组件、AisleLok冷热通道气流管理组件以及EnergyLok机房气流管理服务。

　　该公司致力于以佳气流管理为基础的设计，节约能源，释放滞留能力，提高数据中心系统可靠性，确保关键负载效率的优化，探讨行业内的实践，已成为数据中心气流管理方面的行业先锋。

直流放电法(专利U.S.PatentNo:5,744,962)通过对蓄电池瞬时大电流放电,并测试蓄电池端电压跌落获得蓄电池内阻数据。如图2所示。

　　直流放电法有以下几个主要的缺点:需要对电池进行大电流放电;不能测量蓄电池的极化内阻即电化学内阻;与蓄电池连续放电容量相关性差。

　　但是,直流放电法由于采用了瞬时大电流放电的方式,对于在实际使用中需要使用电池瞬时大电流放电的场合(如发电机启动电池),这种方式还是具有一定使用意义的。

　　交流注入法采用向蓄电池注入一定频率的交流信号实现阻抗的测试。交流法测试原理图如图3所示,将一定幅度的交流电流信号注入到蓄电池中,同时捕捉蓄电池的电压反馈。

　　交流法测试的蓄电池内阻,能在很大程度上体现出蓄电池的电化学特性,其测试方式的科学性较强。同时,由于采用交流注入的方式,会对电池系统中的纹波造成一定影响。对于直流系统特别是对于纹波要求较高的场合,直接采用交流法会对电源质量造成一定的影响。
