太陽能(neng)電動車怎么樣
太(tai)(tai)(tai)(tai)陽能(neng)(neng)(neng)是(shi)(shi)可再生、可持(chi)續性發展的(de)(de)戰略能(neng)(neng)(neng)源(yuan)。當華爾街風暴(bao)席卷全(quan)球(qiu)時,各(ge)先進(jin)技術(shu)國(guo)家無(wu)不在(zai)(zai)新(xin)能(neng)(neng)(neng)源(yuan)領(ling)域下賭注、投資本(ben),以(yi)(yi)期獲得經(jing)(jing)濟復興。特別是(shi)(shi)以(yi)(yi)汽(qi)(qi)車(che)產(chan)業為經(jing)(jing)濟支柱的(de)(de)國(guo)家,尤其在(zai)(zai)新(xin)能(neng)(neng)(neng)源(yuan)汽(qi)(qi)車(che)動力上力圖(tu)有所(suo)創新(xin)和(he)發展,如(ru)在(zai)(zai)電(dian)(dian)(dian)動汽(qi)(qi)車(che)、燃料電(dian)(dian)(dian)池汽(qi)(qi)車(che)領(ling)域紛紛投入巨資,而在(zai)(zai)太(tai)(tai)(tai)(tai)陽能(neng)(neng)(neng)汽(qi)(qi)車(che)領(ling)域更是(shi)(shi)探索(suo)不止,力度加大。由于太(tai)(tai)(tai)(tai)陽能(neng)(neng)(neng)是(shi)(shi)各(ge)種可再生能(neng)(neng)(neng)源(yuan)中最重要的(de)(de)基本(ben)能(neng)(neng)(neng)源(yuan),通過轉(zhuan)(zhuan)換(huan)裝(zhuang)置把太(tai)(tai)(tai)(tai)陽輻射能(neng)(neng)(neng)轉(zhuan)(zhuan)換(huan)成電(dian)(dian)(dian)能(neng)(neng)(neng)利用,屬于太(tai)(tai)(tai)(tai)陽能(neng)(neng)(neng)光發電(dian)(dian)(dian)技術(shu)。光電(dian)(dian)(dian)轉(zhuan)(zhuan)換(huan)裝(zhuang)置通常是(shi)(shi)利用半導體器件的(de)(de)光伏效應原理(li)進(jin)行光電(dian)(dian)(dian)轉(zhuan)(zhuan)換(huan)的(de)(de),因(yin)此也稱太(tai)(tai)(tai)(tai)陽能(neng)(neng)(neng)光伏技術(shu),又(you)稱太(tai)(tai)(tai)(tai)陽能(neng)(neng)(neng)光伏電(dian)(dian)(dian)池。
據報道(dao),太(tai)陽(yang)能(neng)(neng)(neng)光伏技術不僅在先進技術國家得(de)(de)到快(kuai)速(su)發展,中國的(de)(de)太(tai)陽(yang)能(neng)(neng)(neng)產業也(ye)以每年(nian)20%~30%的(de)(de)速(su)度增長(chang)。到2020年(nian),太(tai)陽(yang)能(neng)(neng)(neng)領域的(de)(de)銷售(shou)額將(jiang)(jiang)增加一倍,屆時中國將(jiang)(jiang)有1%的(de)(de)能(neng)(neng)(neng)源(yuan)消耗來自(zi)太(tai)陽(yang)能(neng)(neng)(neng)。今后(hou)幾年(nian),我國太(tai)陽(yang)能(neng)(neng)(neng)使用(yong)(yong)不僅在能(neng)(neng)(neng)源(yuan)領域會(hui)(hui)獲得(de)(de)飛速(su)發展,在汽(qi)車領域的(de)(de)應用(yong)(yong)也(ye)會(hui)(hui)得(de)(de)到不斷(duan)的(de)(de)提(ti)高。

4、高度重視安(an)(an)全(quan)問(wen)題,將主動安(an)(an)全(quan)性列為重要問(wen)題考慮(lv),在車身(shen)的前部特別設計內(nei)保險結構,保障(zhang)駕(jia)駛員的生命(ming)安(an)(an)全(quan),每個座位上都設有三點式安(an)(an)全(quan)帶(dai)、座椅頭枕。另外(wai),前后(hou)保險杠(gang)、高位剎車燈、轉向燈、前大燈、尾燈、后(hou)視鏡(jing)、安(an)(an)全(quan)擋風玻璃、雨刮器(qi)等配置(zhi)一應俱全(quan),而且還可以選裝(zhuang)兒童(tong)安(an)(an)全(quan)座椅等選配裝(zhuang)置(zhi)。
5、作(zuo)為(wei)一種低速車,其設計、生產(chan)和安全標準與傳統(tong)轎車相比毫不(bu)遜色(se)。前后均(jun)有獨立懸掛,四輪鼓(gu)式(shi)制(zhi)動(dong),采用創新(xin)前橋和傳向系統(tong),30km/h速度到停止的(de)剎車距離不(bu)超(chao)過(guo)7.3米(mi)。
6、無(wu)污染(ran)。因為不用燃油,本車(che)不會排放(fang)污染(ran)大(da)氣的(de)有(you)害氣體(ti)。
7、無噪音。沒有內燃(ran)機,行駛時不會(hui)聽到燃(ran)油汽車的轟鳴聲。
8、使(shi)用費用低廉。車上(shang)配有充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器和充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)控制(zhi)器,有兩路電(dian)(dian)(dian)(dian)(dian)源可向動(dong)力電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)。有太(tai)陽(yang)光時(shi)(shi),太(tai)陽(yang)能電(dian)(dian)(dian)(dian)(dian)池(chi)組件(jian)通過(guo)充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)(dian)控制(zhi)器向動(dong)力電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian),公(gong)里行駛(shi)(shi)成本(ben)為零;無太(tai)陽(yang)光時(shi)(shi),隨時(shi)(shi)隨地都能用家用220V電(dian)(dian)(dian)(dian)(dian)源,通過(guo)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器向動(dong)力電(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian),公(gong)里行駛(shi)(shi)成本(ben)為3分錢。
9、易駕(jia)(jia)(jia)駛(shi)。無需(xu)電子點(dian)火,只需(xu)踩踏加速(su)板便可啟動,利用控制(zhi)器控制(zhi)車速(su),勿(wu)需(xu)換檔(dang)、踩離(li)合器,簡(jian)化了駕(jia)(jia)(jia)駛(shi)的復(fu)雜性,避免了因操作失(shi)誤而造成的事故隱患,安全性高。特別適合婦女和老年人駕(jia)(jia)(jia)駛(shi)。
10、方便。由于車身結構簡單,除了定期(qi)更(geng)換動力電(dian)池(chi)外,基本不需日常保(bao)養(yang),省卻了傳統汽(qi)車必須(xu)經(jing)常更(geng)換機(ji)油、添(tian)加冷卻水等定期(qi)養(yang)護的煩(fan)惱。小(xiao)巧玲(ling)瓏(long)的車身,可(ke)以輕而易舉地將車泊入(ru)擁擠不堪的都市停車場。
11、太陽能電動車的(de)(de)最大優(you)勢(shi)是環保、節(jie)能、安全、經濟,批量生產(chan)的(de)(de)成(cheng)(cheng)本將控制在人民幣5-6千元(yuan)左(zuo)右(you),其市場目標鎖定在普通百(bai)姓(xing)家庭(ting),將成(cheng)(cheng)為中(zhong)國老百(bai)姓(xing)買得起、用得起、開得動的(de)(de)物美價廉的(de)(de)交(jiao)通工(gong)具產(chan)品(pin)。

太陽能電動車的驅動方式
太陽能電動車因(yin)具所選擇的元件(jian)不同(tong),布(bu)置(zhi)方案也有所不同(tong)。
主要有3大類:
1、傳統型驅動方式
這種布(bu)置方式(shi)容易(yi)實現(xian),操(cao)作和控制簡(jian)單。但能(neng)量損(sun)耗較(jiao)(jiao)(jiao)高、噪聲(sheng)較(jiao)(jiao)(jiao)大、整車(che)質(zhi)量較(jiao)(jiao)(jiao)重(zhong)、行(xing)駛(shi)速度較(jiao)(jiao)(jiao)低、續駛(shi)里程較(jiao)(jiao)(jiao)短。
2、減速驅動方式
這種方式便(bian)于布置、較易驅(qu)動、質(zhi)量輕(qing)、噪聲小。但(dan)控制(zhi)相對復雜(za),并有一定的能(neng)量損(sun)耗。
3、獨立驅動方式
這種驅動方式動力傳動系元件最(zui)少、結(jie)構(gou)最(zui)簡單、噪聲(sheng)最(zui)低、車重最(zui)輕、可(ke)控性好,但造價(jia)高,控制成為關鍵問(wen)題(ti)。
太陽能電動車工作原理
陽光照射電池陣列時,產生光生電流。能量(電流)通過峰值功率跟蹤器(qi)2被直(zhi)接傳送到(dao)電(dian)(dian)機(ji)控制(zhi)(zhi)器(qi)中,驅動電(dian)(dian)機(ji)5旋轉(zhuan),使車輛(liang)行駛(shi)。剩(sheng)余電(dian)(dian)量(liang)由(you)蓄電(dian)(dian)池儲存起來(lai),以便太陽電(dian)(dian)池板電(dian)(dian)量(liang)不足或陰雨天氣時驅動電(dian)(dian)機(ji)。這一過程(cheng)由(you)控制(zhi)(zhi)器(qi)控制(zhi)(zhi)。車輛(liang)的啟動、加(jia)速(su)、轉(zhuan)向(xiang)、制(zhi)(zhi)動由(you)駕(jia)駛(shi)員操縱。
太(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)是(shi)一(yi)種對光(guang)有(you)響應并能(neng)(neng)將光(guang)轉(zhuan)換成(cheng)電(dian)(dian)(dian)(dian)力(li)的(de)器件裝置。能(neng)(neng)產(chan)生(sheng)光(guang)伏效應的(de)材(cai)料(liao)有(you)許多種,如單晶(jing)(jing)硅(gui)(gui)、多晶(jing)(jing)硅(gui)(gui)、非晶(jing)(jing)硅(gui)(gui)、砷化鎵、硒銦(yin)銅等,它們的(de)發電(dian)(dian)(dian)(dian)原(yuan)(yuan)理基本相(xiang)同。以(yi)晶(jing)(jing)體為(wei)例(li):P型(xing)(xing)晶(jing)(jing)體硅(gui)(gui)經(jing)過摻雜磷可得N型(xing)(xing)硅(gui)(gui),形成(cheng)P-N結。當光(guang)線照(zhao)射太(tai)陽(yang)(yang)能(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)陣列(lie)(lie)板的(de)表面(mian)時,一(yi)部(bu)分光(guang)子(zi)(zi)被硅(gui)(gui)材(cai)料(liao)吸收,光(guang)子(zi)(zi)的(de)能(neng)(neng)量傳遞給了(le)硅(gui)(gui)原(yuan)(yuan)子(zi)(zi),使電(dian)(dian)(dian)(dian)子(zi)(zi)產(chan)生(sheng)了(le)躍遷,成(cheng)為(wei)自由電(dian)(dian)(dian)(dian)子(zi)(zi),在P-N結兩(liang)側(ce)集驟形成(cheng)了(le)電(dian)(dian)(dian)(dian)位差,當外部(bu)電(dian)(dian)(dian)(dian)路接通時,在該電(dian)(dian)(dian)(dian)壓的(de)作用(yong)(yong)下,將會有(you)電(dian)(dian)(dian)(dian)流(liu)流(liu)過外部(bu)電(dian)(dian)(dian)(dian)路,從而產(chan)生(sheng)一(yi)定(ding)的(de)輸出功率。這(zhe)個過程的(de)實質是(shi):光(guang)子(zi)(zi)能(neng)(neng)量轉(zhuan)換成(cheng)電(dian)(dian)(dian)(dian)能(neng)(neng)的(de)過程。太(tai)陽(yang)(yang)能(neng)(neng)陣列(lie)(lie)電(dian)(dian)(dian)(dian)池(chi)板是(shi)由光(guang)敏半導體材(cai)料(liao)制成(cheng)的(de),大多使用(yong)(yong)硅(gui)(gui)化合物。
根(gen)據所用材(cai)(cai)(cai)料(liao)(liao)的(de)不(bu)同(tong),太(tai)(tai)陽(yang)(yang)能電池(chi)(chi)(chi)板可分(fen)(fen)為:硅(gui)太(tai)(tai)陽(yang)(yang)能電池(chi)(chi)(chi);以(yi)無(wu)機鹽(yan)如砷化鎵III-V化合物、硫(liu)化鎘(ge)、硒銦銅等多(duo)元化合物為材(cai)(cai)(cai)料(liao)(liao)的(de)電池(chi)(chi)(chi);功能高(gao)分(fen)(fen)子材(cai)(cai)(cai)料(liao)(liao)制(zhi)備的(de)太(tai)(tai)陽(yang)(yang)能電池(chi)(chi)(chi);和(he)納米晶太(tai)(tai)陽(yang)(yang)能電池(chi)(chi)(chi)等。不(bu)論以(yi)何種材(cai)(cai)(cai)料(liao)(liao)來制(zhi)作電池(chi)(chi)(chi),對(dui)太(tai)(tai)陽(yang)(yang)能電池(chi)(chi)(chi)材(cai)(cai)(cai)料(liao)(liao)一般(ban)的(de)要(yao)求有:半(ban)導(dao)體材(cai)(cai)(cai)料(liao)(liao)的(de)禁帶不(bu)能太(tai)(tai)寬;要(yao)有較高(gao)的(de)光電轉換效(xiao)率(lv);材(cai)(cai)(cai)料(liao)(liao)本身對(dui)環境不(bu)造成污染;材(cai)(cai)(cai)料(liao)(liao)便(bian)于工業(ye)化生產(chan)且材(cai)(cai)(cai)料(liao)(liao)性能穩定。基于以(yi)上(shang)幾(ji)個方面(mian)考(kao)慮,硅(gui)是(shi)最理想的(de)太(tai)(tai)陽(yang)(yang)能電池(chi)(chi)(chi)材(cai)(cai)(cai)料(liao)(liao),這也是(shi)太(tai)(tai)陽(yang)(yang)能電池(chi)(chi)(chi)板以(yi)硅(gui)材(cai)(cai)(cai)料(liao)(liao)為主的(de)主要(yao)原(yuan)因。
太(tai)陽能(neng)電(dian)池(chi)(chi)組件是(shi)供(gong)電(dian)系(xi)統(tong)中(zhong)的(de)(de)(de)核心部分,也是(shi)太(tai)陽能(neng)供(gong)電(dian)系(xi)統(tong)中(zhong)價值(zhi)最高的(de)(de)(de)部分。其作(zuo)用(yong)是(shi)將(jiang)太(tai)陽的(de)(de)(de)輻射能(neng)量轉(zhuan)換為電(dian)能(neng),或送往蓄電(dian)池(chi)(chi)中(zhong)存儲起(qi)來,或推(tui)動負載工作(zuo)。太(tai)陽能(neng)組件中(zhong)的(de)(de)(de)質量和成(cheng)本將(jiang)直接決定整(zheng)個系(xi)統(tong)的(de)(de)(de)質量和成(cheng)本。太(tai)陽能(neng)控(kong)制(zhi)器(qi)的(de)(de)(de)作(zuo)用(yong)是(shi)管(guan)理和控(kong)制(zhi)整(zheng)個系(xi)統(tong)的(de)(de)(de)工作(zuo)狀態,并對蓄電(dian)池(chi)(chi)起(qi)到充電(dian)保(bao)護、過放(fang)電(dian)保(bao)護的(de)(de)(de)作(zuo)用(yong),與純電(dian)動汽車的(de)(de)(de)電(dian)動源控(kong)制(zhi)管(guan)理系(xi)統(tong)具有相同的(de)(de)(de)作(zuo)用(yong)。在(zai)(zai)溫(wen)差較大的(de)(de)(de)地方(fang),合格的(de)(de)(de)控(kong)制(zhi)器(qi)還應具備溫(wen)度(du)補償(chang)的(de)(de)(de)功能(neng)。其它附加功能(neng)如光控(kong)、時控(kong)等(deng)應當都是(shi)控(kong)制(zhi)器(qi)的(de)(de)(de)可選項。蓄電(dian)池(chi)(chi)的(de)(de)(de)作(zuo)用(yong)是(shi)在(zai)(zai)有光照時將(jiang)太(tai)陽能(neng)電(dian)池(chi)(chi)組件所提供(gong)出(chu)的(de)(de)(de)電(dian)能(neng)儲存起(qi)來,到需要的(de)(de)(de)時候(hou)再釋放(fang)出(chu)來。
太陽(yang)能電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組件是(shi)由(you)(you)單個(ge)(ge)(ge)(ge)光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)拼接(jie)組成,或由(you)(you)折疊式支架拼接(jie)組成陣(zhen)列。因為單個(ge)(ge)(ge)(ge)光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(如(ru)硅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi))的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)太低(di),所以(yi)都要把它們串、并聯(lian)構(gou)成有(you)實用價(jia)值的(de)(de)光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)板,陣(zhen)列成一個(ge)(ge)(ge)(ge)應用單元,然(ran)后根據供(gong)電(dian)(dian)(dian)(dian)要求(qiu),再(zai)由(you)(you)多個(ge)(ge)(ge)(ge)應用單元的(de)(de)串、并聯(lian)組成整個(ge)(ge)(ge)(ge)太陽(yang)能光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)板的(de)(de)供(gong)電(dian)(dian)(dian)(dian)組件。蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組是(shi)太陽(yang)能光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)儲能裝置,在夜間(jian)或光(guang)(guang)照不(bu)足及負(fu)載消耗超出光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)發電(dian)(dian)(dian)(dian)量時,由(you)(you)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組向負(fu)載供(gong)電(dian)(dian)(dian)(dian)。為了減輕(qing)整個(ge)(ge)(ge)(ge)系統(tong)的(de)(de)重(zhong)量,應采用高能蓄電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)組。

在設計電動車整個供電系統時應綜合考慮以下幾個方面:
一是(shi)光(guang)(guang)(guang)強與(yu)負載。太(tai)陽能(neng)光(guang)(guang)(guang)伏(fu)電池是(shi)一種光(guang)(guang)(guang)電轉換裝置,其輸出功率(lv)的(de)大小(xiao)取決于光(guang)(guang)(guang)照的(de)強度(du),要拼裝多大的(de)太(tai)陽能(neng)光(guang)(guang)(guang)伏(fu)電池組件主要取決于能(neng)夠(gou)接受光(guang)(guang)(guang)照的(de)強度(du)及所用負載的(de)大小(xiao)。
二是蓄電池組的選擇。要根據光伏電池組合的發電容量來選擇蓄電池組的容量,以便在陰(yin)雨天及晚上可(ke)以由蓄電(dian)池(chi)向負載供(gong)電(dian),為了減輕系統(tong)重要,最好選用高比能量的蓄電(dian)池(chi)。
三是機(ji)械強(qiang)。考慮到電(dian)(dian)動(dong)汽車的整個(ge)供電(dian)(dian)系(xi)統(tong)都是在(zai)運動(dong)和運行中(zhong)使用,必須考慮系(xi)統(tong)的機(ji)械強(qiang)度(du),耐(nai)(nai)腐蝕性(xing),耐(nai)(nai)氣(qi)候變(bian)化(hua)等各種(zhong)因素。太陽能光伏電(dian)(dian)池組陣列應采取高(gao)強(qiang)度(du)鋼化(hua)玻(bo)璃外殼,支架(jia)系(xi)統(tong)應采用高(gao)強(qiang)度(du)材料。使整個(ge)供電(dian)(dian)系(xi)統(tong)具(ju)有便于(yu)運行、重(zhong)量(liang)輕、效率高(gao)、可靠(kao)性(xing)好(hao)、造價低等優勢。
太(tai)陽能(neng)(neng)光(guang)(guang)伏(fu)電(dian)(dian)池板(ban)是(shi)將(jiang)太(tai)陽能(neng)(neng)量轉變為電(dian)(dian)能(neng)(neng),是(shi)因為光(guang)(guang)子(zi)在日(ri)光(guang)(guang)下產(chan)生(sheng)能(neng)(neng)量帶動(dong)電(dian)(dian)子(zi)從一(yi)個(ge)半運(yun)動(dong)的(de)金屬粒子(zi)的(de)一(yi)層(ceng)轉移到另一(yi)層(ceng)面,電(dian)(dian)子(zi)的(de)運(yun)動(dong)產(chan)生(sheng)了通用的(de)電(dian)(dian)力。太(tai)陽能(neng)(neng)光(guang)(guang)伏(fu)電(dian)(dian)池板(ban)可以(yi)由光(guang)(guang)電(dian)(dian)轉化率、能(neng)(neng)量比大(da)小(xiao)來選(xuan)擇。由于許(xu)多獨立的(de)硅片被(bei)組合(he),形成龐大(da)的(de)太(tai)陽能(neng)(neng)光(guang)(guang)伏(fu)陣列(lie),并產(chan)生(sheng)能(neng)(neng)夠電(dian)(dian)動(dong)汽車驅(qu)動(dong)的(de)電(dian)(dian)能(neng)(neng),而(er)這(zhe)(zhe)種電(dian)(dian)能(neng)(neng)量還必須(xu)達到高(gao)電(dian)(dian)壓、高(gao)功(gong)率的(de)程度,這(zhe)(zhe)就要有一(yi)個(ge)重要的(de)系統(tong)-電(dian)(dian)力控制(zhi)系統(tong)。
電(dian)(dian)動(dong)(dong)汽車的(de)(de)(de)(de)心(xin)臟部位就(jiu)(jiu)是電(dian)(dian)源(yuan)及其蓄電(dian)(dian)池(chi)組(zu),而運行系(xi)(xi)統(tong)(tong)(tong)(tong)基本上(shang)是由電(dian)(dian)源(yuan)、電(dian)(dian)控(kong)(kong)、電(dian)(dian)機來組(zu)成(cheng)。而在(zai)(zai)太(tai)(tai)陽能(neng)(neng)電(dian)(dian)動(dong)(dong)汽車上(shang)其控(kong)(kong)制系(xi)(xi)統(tong)(tong)(tong)(tong)不僅僅控(kong)(kong)制電(dian)(dian)動(dong)(dong)源(yuan)(電(dian)(dian)池(chi)),還要增加太(tai)(tai)陽能(neng)(neng)光(guang)(guang)伏電(dian)(dian)池(chi)陣列的(de)(de)(de)(de)控(kong)(kong)制功(gong)能(neng)(neng)。太(tai)(tai)陽能(neng)(neng)光(guang)(guang)伏電(dian)(dian)池(chi)所(suo)供應的(de)(de)(de)(de)電(dian)(dian)壓與蓄電(dian)(dian)池(chi)組(zu)飽和(he)(he)電(dian)(dian)壓基本相同(tong),可以直(zhi)接耦合,在(zai)(zai)太(tai)(tai)陽能(neng)(neng)功(gong)率充(chong)(chong)足時,多(duo)余的(de)(de)(de)(de)能(neng)(neng)量進入(ru)儲能(neng)(neng)的(de)(de)(de)(de)蓄電(dian)(dian)池(chi),在(zai)(zai)太(tai)(tai)陽能(neng)(neng)光(guang)(guang)電(dian)(dian)功(gong)率不足時由蓄電(dian)(dian)池(chi)完成(cheng)電(dian)(dian)力驅動(dong)(dong)的(de)(de)(de)(de)任務。這(zhe)些,必(bi)須由控(kong)(kong)制系(xi)(xi)統(tong)(tong)(tong)(tong)來完成(cheng)。控(kong)(kong)制系(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)(de)(de)功(gong)能(neng)(neng)就(jiu)(jiu)是對(dui)(dui)充(chong)(chong)電(dian)(dian)和(he)(he)放電(dian)(dian)的(de)(de)(de)(de)過(guo)程進行控(kong)(kong)制和(he)(he)保護,這(zhe)樣才(cai)能(neng)(neng)保證對(dui)(dui)整個電(dian)(dian)動(dong)(dong)源(yuan)系(xi)(xi)統(tong)(tong)(tong)(tong)的(de)(de)(de)(de)正常充(chong)(chong)電(dian)(dian)、放電(dian)(dian)及其對(dui)(dui)電(dian)(dian)動(dong)(dong)汽車的(de)(de)(de)(de)驅動(dong)(dong)。最(zui)簡(jian)單的(de)(de)(de)(de)控(kong)(kong)制系(xi)(xi)統(tong)(tong)(tong)(tong)也應該起到以下三(san)個方面的(de)(de)(de)(de)作用:
一是按照使(shi)用要求給出穩定(ding)的電壓、電流;
二是蓄電池過充電或過放電時可以報警或自動切(qie)斷電路;
三是(shi)負載(zai)發生短路時可以自動切(qie)斷電(dian)源電(dian)路。
控制系統是控制太(tai)(tai)陽能(neng)(neng)光(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)陣(zhen)列板對(dui)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)充電(dian)(dian)(dian)(dian)以(yi)及蓄電(dian)(dian)(dian)(dian)池(chi)(chi)和(he)太(tai)(tai)陽能(neng)(neng)電(dian)(dian)(dian)(dian)池(chi)(chi)對(dui)負(fu)(fu)(fu)(fu)載(zai)的(de)(de)放電(dian)(dian)(dian)(dian)過程(cheng),實現(xian)對(dui)太(tai)(tai)陽能(neng)(neng)光(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)和(he)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)科學(xue)管(guan)理,指(zhi)示蓄電(dian)(dian)(dian)(dian)池(chi)(chi)過壓、欠(qian)壓等(deng)(deng)運行狀態,具有(you)(you)兩(liang)路(lu)(lu)(lu)負(fu)(fu)(fu)(fu)載(zai)輸(shu)出的(de)(de)管(guan)理,或(huo)兩(liang)路(lu)(lu)(lu)負(fu)(fu)(fu)(fu)載(zai)可以(yi)隨意設置為同時工作、分時工作或(huo)單獨工作等(deng)(deng)模式,同時具有(you)(you)負(fu)(fu)(fu)(fu)載(zai)過流、短(duan)路(lu)(lu)(lu)保護功(gong)能(neng)(neng),具有(you)(you)較高的(de)(de)自動化和(he)智能(neng)(neng)化水平。其(qi)硬件(jian)結構(gou)主要(yao)由電(dian)(dian)(dian)(dian)壓采(cai)(cai)集(ji)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)、負(fu)(fu)(fu)(fu)載(zai)輸(shu)出控制與檢測電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)、指(zhi)示或(huo)顯示電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)及鍵盤電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)等(deng)(deng)部分組成。電(dian)(dian)(dian)(dian)壓采(cai)(cai)集(ji)電(dian)(dian)(dian)(dian)路(lu)(lu)(lu)包括太(tai)(tai)陽能(neng)(neng)光(guang)伏(fu)電(dian)(dian)(dian)(dian)池(chi)(chi)板和(he)蓄電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓采(cai)(cai)集(ji),用于太(tai)(tai)陽光(guang)線(xian)強弱(ruo)的(de)(de)識別以(yi)及蓄電(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)壓的(de)(de)獲取(qu)等(deng)(deng)。
在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)動源(yuan)控制系(xi)(xi)統利用(yong)子(zi)系(xi)(xi)統的(de)(de)控制功能對蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)進行充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)管(guan)理時(shi)(shi),若太(tai)陽能光(guang)伏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)正常充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)時(shi)(shi),控制器將關斷負(fu)載(zai)(zai),以(yi)保(bao)證負(fu)載(zai)(zai)不(bu)被損傷,當(dang)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)高(gao)于(yu)保(bao)護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)時(shi)(shi)自(zi)動關斷對蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian);此后若電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)掉至維護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)時(shi)(shi),蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)進入(ru)浮充狀態,當(dang)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)低于(yu)維護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)時(shi)(shi),啟(qi)動的(de)(de)應當(dang)是(shi)均充狀態。當(dang)蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)低于(yu)保(bao)護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)時(shi)(shi),控制系(xi)(xi)統應當(dang)自(zi)動關閉負(fu)載(zai)(zai)開(kai)關,以(yi)保(bao)護蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)不(bu)受損壞。在蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)負(fu)載(zai)(zai)關閉后,有(you)兩路充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路可選擇使(shi)用(yong),在太(tai)陽光(guang)照較強時(shi)(shi)自(zi)動啟(qi)動太(tai)陽能光(guang)伏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)板充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路,使(shi)其發揮更大功效,或使(shi)用(yong)外充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)進行快速充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。
