【摘要】：隨著電子技術(shù)的快速發(fā)展，智能手機、平板電腦等便攜式設(shè)備的功能變得更加豐富，給生活和通訊帶來了極大的便利，同時也增加了消費者使用便攜式設(shè)備的頻率。然而目前便攜式設(shè)備中鋰電池的電量無法給設(shè)備提供較長的續(xù)航時間，人們在外出時經(jīng)常會遇到手機沒電等問題。此外，目前便攜式設(shè)備大多采用有線充電的方式，如果消費者找不到數(shù)據(jù)線就無法給移動設(shè)備充電。因此采用無線充電方式給便攜設(shè)備充電的相關(guān)產(chǎn)品，開始逐漸在市場上出現(xiàn)。 本文針對便攜式設(shè)備鋰電池充電問題，分別設(shè)計了移動電源和無線充電器，從而滿足消費者對充電方式的不同需求。移動電源自身攜帶了大容量的鋰電池組，升壓模塊將電池電壓升高后，通過USB數(shù)據(jù)線給便攜式設(shè)備充電。此款移動電源具有較高的電能轉(zhuǎn)化效率，并且具有兩個USB輸出口可同時為兩個便攜式設(shè)備充電。無線充電器雖然電能轉(zhuǎn)換效率不高，但在充電過程中便攜式設(shè)備無需通過USB數(shù)據(jù)線與其連接，充電方式更為便捷。 本文設(shè)計的移動電源中主要包括基于ASC8513的鋰電池充電模塊，基于ME2109和FP6291的升壓模塊，以及S-8261ABPMD鋰電池保護模塊，通過HT46R065B單片機實現(xiàn)系統(tǒng)控制。此款移動電源自身的最大充電電流和輸出電流均可達(dá)到2A，比普通產(chǎn)品的1A電流高出1倍，并具有多重電路保護和自動開機、關(guān)機等人性化功能。無線充電器通過Atmega16單片機產(chǎn)生頻率可調(diào)的方波來驅(qū)動全橋逆變器，將直流電能轉(zhuǎn)換為變化的磁場，，最后傳遞到接收端將其轉(zhuǎn)為電能給鋰電池充電。此款無線充電器開機后能夠自動識別負(fù)載，并在充電過程中時刻檢測電流、電壓等反饋信號，從而控制系統(tǒng)在安全的范圍內(nèi)工作。
[Abstract]:With the rapid development of electronic technology, the functions of portable devices such as smartphones and tablets have become more abundant, which has brought great convenience to life and communication, and also increased the frequency of consumers using portable devices. However, at present, the power of lithium battery in portable devices can not provide a long life for the device, people often encounter mobile phone power and other problems when they go out. In addition, most portable devices use wired charging, if consumers can not find a data line to charge mobile devices. Therefore, the use of wireless charging mode to charge portable devices related products, began to gradually appear in the market. In this paper, aiming at the charging problem of lithium battery, mobile power supply and wireless charger are designed respectively to meet the different needs of consumers for charging methods. The mobile power supply itself carries a large capacity lithium battery pack, and the boost module increases the battery voltage and charges the portable device through the USB data line. This mobile power supply has high power conversion efficiency and has two USB ports to charge two portable devices at the same time. Although the power conversion efficiency of wireless charger is not high, the portable device does not need to be connected to it through USB data line in the charging process, and the charging mode is more convenient. The mobile power supply designed in this paper mainly includes lithium battery charging module based on ASC8513, boost module based on ME2109 and FP6291, and S-8261ABPMD lithium battery protection module, which is controlled by HT46R065B single chip microcomputer. The maximum charging current and output current of this mobile power supply can reach 2A, which is twice as high as the 1A current of ordinary products, and has multiple circuit protection, automatic boot, shutdown and other humanized functions. The wireless charger drives the full-bridge inverter through the square wave with adjustable frequency generated by Atmega16 single chip microcomputer, converts the DC electric energy into a changing magnetic field, and finally transmits it to the receiver to convert it into electric energy to charge the lithium battery. This wireless charger can automatically identify the load after switching on, and detect current, voltage and other feedback signals at all times in the charging process, so as to control the system to work in a safe range.
