Quick Charge, or Fast Charge technology, enables rapid charging of electronic devices and is widely utilized in smartphones, tablets, laptops, and electric vehicles, with e-cigarettes also reaping its benefits. Charging time is influenced by multiple factors including battery capacity, charger type, and charging current, typically ranging from 30 minutes to 4 hours. With Quick Charge technology, the charging performance of various e-cigarettes varies; for instance, a disposable e-cigarette with an 850mAh battery can reach 80% charge in just 45 minutes, while a 700mAh variant requires only 20 minutes. More advanced devices, such as high-capacity vape mods, can fully charge a 3700mAh battery in as little as 15 minutes. Generally, quick-change e-cigarettes complete charging within 12 to 18 minutes, with some products capable of charging a 550mAh battery in a mere 9 minutes.
The operating principle of Quick Charge technology primarily involves increasing voltage and current, or enhancing both simultaneously, to maximize charging power. However, this advancement also results in increased heat and potential safety risks, necessitating effective heat dissipation designs. Factors influencing e-cigarette charging include the initial battery level, charging current, battery capacity, charger type, and device type. In summary, the application of Quick Charge technology significantly enhances the convenience of e-cigarettes, providing users with a superior experience.
快充技术(Quick Charge、Fast Charge)是指一种能在较短时间内为电子设备的电池充入较多电量的技术,比如手机、平板电脑、笔记本电脑、电动汽车等,电子烟也不例外。
电子烟的充电时长受到电池容量、充电器类型、充电电流等多种因素影响,充电时长区间在30分钟到4个小时。
而使用快充技术后,不同类型电子烟有不同表现。一次性电子烟要求简单,850mAh的一次性电子烟可在45分钟充到80%,700mAh的一次性电子烟可在20分钟充到80%。
而方案板更智能的大烟盒子还能更快,3700 mAh 仅需 15 分钟;快充换弹式电子烟一般是12-18分钟,还有出现过9 分钟内充满 550mAh 电池的换弹式电子烟。
一、快充技术工作原理
1.提高电压
基于功率(P)= 电压(U)× 电流(I)的公式,在电池电量一定的情况下,升高电压可以提高充电功率,从而缩短充电时间。
不过,提高电压会在充电过程中产生更多热量,可能加速电池老化并带来安全隐患,所以需要有良好的散热设计和安全保护机制。
2.提高电流
在电压一定的情况下,增加电流也能提高充电功率。可以通过并联电路的方式进行分流,降低每条电路所承受的压力,从而实现大电流充电。
这种方式的优点是充电时产生的热量相对较少,安全性较高,但需要特制的充电线和充电接口来支持大电流传输,成本可能会增加。
3.同时提高电压和电流
这种方式能最大程度地提高充电功率,但对充电器、手机以及充电数据线的电子元件要求极高,需要具备更好的散热性能和更高的耐压、耐流能力。同时,充电过程中产生的热量也会更多,需要更复杂的散热管理。
二、影响电子烟充电的因素
1.电池电量百分比
初始电池电量不同,充电时间不同。电量耗尽时充电时间长,部分耗尽时充电时间较短。
2.充电电流
电流越大充电时间可能越短,但电流过大会损坏电池或引发安全隐患。
3.电池容量
容量越大,完全充电所需时间越长。
4.充电器类型
充电器质量影响充电时间,应使用与设备规格匹配的充电器确保足够功率输出。
5.设备类型
不同类型的电子烟设备,如一次性、换弹式、开放式、可调功率式等,充电时间不同。
