对于Qualcomm Quick Charge 2.0快速充电技术的优势,我们已经说得很多了。也谈及了不少在运营商、零售商和设备与配件制造商支持下,迅速扩大的快速充电设备和适配器生态系统。我们提供了常见问题的解答手册,但对于社区成员来说,如果希望获得有关超快速电池充电技术的深度解读,仍然会有许多疑问。


Qualcomm Quick Charge 2.0来了!其可扩展性支持应用于不同类型的电子产品,100%兼容于当前的充电系统。Quick Charge 2.0对接口并无特别要求,它使用D+/D-数据线,支持USB Type-A,micro USB,USB Type-A和其他专用连接器。目前,已有20多家OEM厂商支持这一技术,市面上可以买到70多种配件。

与传统USB充电方法不同,Quick Charge 2.0端到端解决方案可以利用高功率这一优势,快速有效地为设备充电。Quick Charge 2.0 Class A 通过micro USB连接器提供最高达24瓦的功率,通过Type-C连接器提供36瓦的功率,Quick Charge2.0 Class B提供60瓦或更高的功率。可以预见,未来充电技术的进步将带来更大的改进。

通过多层次的电压限制、电流限制和温度保护,无论使用什么连接器,Qualcomm Quick Charge 2.0的独特设计都可确保健康的电池生命周期。且这一切都集成在Quick Charge 2.0的组件中,无需连接外部器件。

Quick Charge 2.0的实施通常是一个简单、低成本的充电解决方案。它已经在许多Qualcomm Technologies的PMIC(电源管理集成电路)中实施,在其中接受移动设备应用验证和测试。如果使用其他解决方案,额外电路就会占用更多的印制电路板空间。

这项专利技术使用无噪声数据线进行有效的信号交换和通信,同时支持高效率的电力传输。Qualcomm Quick Charge 2.0快速、高效,遵循一个全面的认证程序。随着Qualcomm Quick Charge向智能手机用户提供进一步完善的充电解决方案,更多令人兴奋的电池管理技术也将会问世。
