【摘要】:隨著鉛酸蓄電池產(chǎn)業(yè)的高速發(fā)展,它已是我國(guó)新能源領(lǐng)域中重要的組成部分。鉛酸蓄電池具有循環(huán)性好、續(xù)航時(shí)間持久,且價(jià)格低廉等特點(diǎn),在我們?nèi)粘I钪凶鳛閯?dòng)力能源起到非常重要的作用。通常,由于單體鉛酸蓄電池的驅(qū)動(dòng)能力不強(qiáng),因此蓄電池必須以電池組的形式才能給電動(dòng)車提供足夠的動(dòng)力。蓄電池在正常工作時(shí),由于其組內(nèi)的單體蓄電池存在性能上的差異,如果這種差異過(guò)大,會(huì)對(duì)整體蓄電池的性能造成很大的影響,最終導(dǎo)致動(dòng)力鉛酸蓄電池組的使用壽命提前終止。目前,國(guó)內(nèi)大都數(shù)蓄電池生產(chǎn)廠商由人工的方法進(jìn)行電池配組。采用人工的電池配組方法會(huì)有測(cè)量電壓不精確、記錄電壓繁瑣、配組運(yùn)算大等問(wèn)題。基于Wi-Fi的蓄電池自動(dòng)配組系統(tǒng)需要較少的人工參與,具有配組的準(zhǔn)確率好、成功率高、穩(wěn)定性優(yōu)等特點(diǎn),改善了蓄電池配組現(xiàn)狀。本文的研究工作主要有:(1)學(xué)習(xí)Wi-Fi組網(wǎng)技術(shù),將一種基于C/S架構(gòu)的分布式局域網(wǎng)應(yīng)用在蓄電池自動(dòng)配組系統(tǒng)之中,每個(gè)設(shè)備終端通過(guò)Socket套接字與服務(wù)器通信,構(gòu)成一主多從的“星”式系統(tǒng)架構(gòu);(2)分析現(xiàn)有的蓄電池生產(chǎn)廠商的配組工藝,提出一種基于圖割理論的快速配組算法;(3)運(yùn)用C#語(yǔ)言開(kāi)發(fā)了上位機(jī)服務(wù)器軟件,為多個(gè)下位機(jī)手持式配組儀提供服務(wù);(4)在下位機(jī)手持式配組儀上移植了μC/OS-II實(shí)時(shí)操作系統(tǒng),用來(lái)完成多任務(wù)工作,通過(guò)4.3寸液晶觸摸屏,設(shè)計(jì)了友好的人機(jī)交互界面,提高自動(dòng)配組的效率;(5)編寫下位機(jī)Bootloader程序,方便用戶直接通過(guò)上位機(jī)軟件對(duì)手持式配組儀終端進(jìn)行程序更新。(6)設(shè)計(jì)了上位機(jī)和下位機(jī)之間的通信協(xié)議、CRC校驗(yàn)算法以及狀態(tài)機(jī)的數(shù)據(jù)接收方法。經(jīng)現(xiàn)場(chǎng)測(cè)試,與傳統(tǒng)的人工配組相比,基于Wi-Fi的蓄電池自動(dòng)配組系統(tǒng)具有配組效率高、組內(nèi)單電池的一致性好、操作界面方便、使用簡(jiǎn)單等優(yōu)點(diǎn)。在3200個(gè)現(xiàn)場(chǎng)采集電池?cái)?shù)據(jù)的驗(yàn)證下,電池配組的成功率高達(dá)96.5%,相比相同數(shù)據(jù)的人工配組的成功率提高了44.4%,且配組后的電池組中單體電池一致性也有較大提高,基本達(dá)到了預(yù)期目標(biāo)。
[Abstract]:With the rapid development of lead-acid battery industry, it has become an important part of the new energy field in China. Lead acid battery has the characteristics of good circulation, lasting life, and low price. In our daily life as a power source of energy plays a very important role. Usually because of the single lead acid battery drive capacity is not strong. So the battery must be in the form of battery pack to provide enough power to the electric vehicle. When the battery is in normal operation, because of the difference in the performance of the single battery, if the difference is too big. Will have a great impact on the performance of the whole battery, eventually leading to the end of the life of the power lead-acid battery. Most of the domestic battery manufacturers use artificial method to match the battery. Using artificial battery matching method will lead to inaccurate measurement of voltage and tedious recording voltage. Wi-Fi based battery automatic matching system needs less manual participation, and has the characteristics of good accuracy, high success rate and excellent stability. The current situation of battery allocation is improved. The main research work in this paper is to learn Wi-Fi networking technology and apply a distributed LAN based on C / S architecture to the battery automatic assembly system. Each device terminal communicates with the server through Socket socket to form a master multi-slave "star" system structure; 2) analyzing the existing technology of battery-making manufacturer, and putting forward a fast algorithm based on graph cutting theory. C # language is used to develop the upper computer server software, which can provide service for many lower computer handheld distribution devices. The 渭 C / OS-II real time operating system is transplanted on the hand-held matching device of the lower computer, which is used to accomplish the multitask work. The friendly man-machine interface is designed through the 4.3-inch LCD touch screen. Improve the efficiency of automatic matching; 5) write the Bootloader program of the lower computer. The communication protocol between the upper computer and the lower computer is designed. CRC calibration algorithm and data receiving method of state machine. Compared with the traditional manual matching system, the automatic battery matching system based on Wi-Fi has high efficiency. The single battery in the group has the advantages of good consistency, convenient operation interface, simple use and so on. Under the verification of the data collected from 3, 200 sites, the success rate of battery matching is as high as 96.5%. Compared with the same data, the success rate of the artificial group is increased by 44.4%, and the consistency of the single cell in the battery pack is also greatly improved, which basically achieves the expected goal.
