Description

模組化充電車
本創作屬於電動汽車領域,具體提供一種模組化充電車。
隨著電動汽車的高速發展和廣泛應用,人們對電動汽車的充電站也提出了更高的要求。為了方便電動汽車在不同場所充電,可移動充電車作為充電站的補充,已越來越廣泛地被應用。但是,目前的充電站和可移動充電車需要為不同規格的電動車配置單獨的充電樁,以滿足充電樁的輸入功率和輸出功率相匹配,導致充電車重複性開發,不僅增加了充電站的研發週期還增加了充電站投放市場的時間。
相應地,本領域需要一種新的可移動充電車來解決上述問題。
為了解決現有技術中的上述問題,即為了解決現有充電車重複性開發的問題,本創作提供了一種模組化充電車。模組化充電車包括主控制器和並聯的至少兩個充放電模組,每個充放電模組包括充電輸入端、電池包、DC/DC變換器和充電輸出端,電池包與充電輸入端和DC/DC變換器連接,DC/DC變換器與充電輸出端連接,主控制器與每個充放電模組的DC/DC變換器相連,用於控制每個充放電模組進行電能的存儲和釋放,以便輸入或輸出不同功率。
在本創作的優選一實施例中,模組化充電車還包括輸入切換模組,輸入切換模組安裝在充電輸入端與電池包之間並且與主控制器相連,用於將多個充電輸入端合成一路。
在本創作的優選一實施例中,輸入切換模組上設置有與充放電模組數量相同的多個接觸器,接觸器用於將電池包連接到充電輸入端。
在本創作的優選一實施例中,模組化充電車還包括與充放電模組的數量相對應的至少兩個輸入控制器,輸入控制器分別與充電輸入端和電池包連接,用於控制電池包的充電操作。
在本創作的優選一實施例中,模組化充電車還包括與充放電模組的數量相對應的至少兩個輸出控制器,輸出控制器連接到DC/DC變換器和主控制器,用於控制DC/DC變換器的放電操作。
在本創作的優選一實施例中,輸出控制器還連接到設置在DC/DC變換器與充電輸出端之間的多個接觸器,以便控制接觸器來連通或斷開DC/DC變換器與充電輸出端之間的連接。
在本創作的優選一實施例中,充電輸入端設置有直流充電樁。
在本創作的優選一實施例中,充電輸入端還設置有交流充電樁,交流充電樁通過AC/DC變換器連接到輸入切換模組。
在本創作的優選一實施例中,主控制器也連接到AC/DC變換器以便控制交流充電樁的操作。
在本創作的優選一實施例中,模組化充電車還包括交流輸入端,交流輸入端也通過AC/DC變換器連接到輸入切換模組。
在本創作的一實施例中,通過主控制器控制多個充放電模組進行電能的釋放和存儲,具體地,主控制器通過輸入切換模組、輸入控制器和輸出控制器,實現各電池包之間既可單獨充電、放電又可任意組合並聯的充電放電,使得模組化充電車能夠輸入或輸出不同功率。
下面參照圖式來描述本創作的優選實施方式。本領域技術人員應當理解的是,這些實施方式僅僅用於解釋本創作的技術原理,並非旨在限制本創作的保護範圍。本領域技術人員可以根據需要對其作出調整,以便適應具體的應用場合。
根據圖1和圖2所示,模組化可移動充電車整體系統包括主控制器、AC/DC變換器、輸入切換模組、輸入控制器、輸出控制器和多個充放電模組,並且每個充放電模組可單獨完成電能的釋放和存儲。
根據圖2所示,每個充放電模組主要包括充電輸入端(位於圖2中輸入切換模組的左側)、電池包、DC/DC變換器和充電輸出端(位於圖2中DC/DC變換器的右側)。充電輸入端、電池包、DC/DC變換器和充電輸出端,按照圖2所示從左至右的順序依次連接,輸入控制器設置在充電輸入端和電池包之間,並且輸入控制器的一端與電池包連接,輸入控制器的另一端與充電輸入端的直流充電樁連接,輸入控制器能夠將電池包的溫度、電量、充電時間等資訊回饋給主控制器和充電輸入端的直流充電樁,以便控制電池包的充電操作。
需要說明的是,充電輸入端和充電輸出端並非具體指某一裝置或部件,這裡的充電輸入端和充電輸出端是對電池包的充電連線端和放電連線端的泛指。
繼續參閱圖2,充電輸入端與直流充電樁電連接,使得直流充電樁能夠對電池包進行充電。DC/DC變換器可將電池包正負極提供的直流電壓轉化為滿足電動汽車需要的直流電壓,進一步將充電輸出端與電動汽車充電口連接,對電動汽車進行充電。當電池包的電量過低時,輸入控制器會將電池包的電量資訊回饋給主控制器,進而停止對電動汽車充電;當電池包進行充電時,輸入控制器會將電池包的即時電量回饋給主控制器和直流充電樁,當電池包被充滿電時,主控制器會命令輸入控制器,使直流充電樁停止向電池供電。
繼續參閱圖1,輸入切換模組包括多個接觸器,充電輸入端與電池包通過接觸器電連接,並且該接觸器還設置有另一個輸入端,通過該輸入端電池包可與交流充電樁或者其他充電功率的充電樁進行連接,以滿足電池包對不同輸入功率的需求。如上所述,輸入控制器除了與充電輸入端和電池包連接以外,還與主控制器相連接。並且,CANaN是輸入控制器N與直流充電樁之間的傳輸信號,CANbN是輸入控制器N與電池包之間的傳輸信號,CANcN是輸入控制器N與主控制器之間的傳輸信號。DC/DC變換器的電流輸出端同樣設置有接觸器,該接觸器與每個輸出控制器連接,使得每個輸出控制器能夠獨立控制該接觸器的通斷。基於此,通過主控制器並結合相應的硬體介面和通信協定,所述充放電模組是可以擴展的。
如圖1所示,各充放電模組上連接充電輸入端和電池包的接觸器均佈置在輸入切換模組上,並且AC/DC變換器能夠使交流充電樁給每個充放電模組中電池充電,滿足長時間慢充輸入和無法找到直流樁時的應急需求。所有接觸器都分別與AC/DC變換器的電流輸出端連接,DC/DC變換器的電流輸出端的接觸器均與輸出控制器連接,以便輸出控制器能夠控制這些接觸器的通斷,並且所有接觸器另一端的電源輸出線最終連接到一條總的電源輸出線上,以便各充放電模組能夠並聯輸出,對各種型號的電動汽車進行充電作業。
繼續參閱圖1,一方面,主控制器分別與各充放電模組的輸入控制器連接,用於監測和控制各單路電池包;另一方面,主控制器分別與輸入切換模組上的接觸器連接,用於控制各接觸器的通斷,將多路輸入合併成一路,以適應不同的輸入功率工況,實現不同充電倍率對移動充電車內的一塊儲能電池充電;再者,主控制器與輸出控制器連接,通過控制輸出控制器對各DC/DC變換器的電流輸出端的接觸器進行投切,可將多路輸出合成一路,以適應不同的輸出功率需求,實現不同充電倍率對外部車輛的充電;另外,主控制器與AC/DC變換器連接,用於例如在交流慢充時,將相關電池包的電壓、電流、溫度、電量等資料回饋給交流充電樁,以便控制交流充電樁或AC/DC變換器的操作。
綜上所述,在充電車充電時,可以通過各充放電模組的直流充電樁分別給對應的電池包充電;也可以通過主控制器控制輸入投切範本上的接觸器將多路輸入合成一路,對充電車內的某一電池包進行集中充電;當沒有直流充電樁時,還可以通過AC/DC變換器,對每個充放電模組中的電池包進行充電。在充電車給電動汽車充電時,主控制器會根據不同規格的電動汽車將資訊發送給輸出控制器,輸出控制器控制DC/DC變換器的電流輸出端的接觸器,將多路輸出合成一路,對電動汽車進行充電。
至此,已經結合圖式所示的優選實施方式描述了本創作的技術方案,但是,所屬領域具通常知識者容易理解的是,本創作的保護範圍顯然不局限於這些具體實施方式。在不偏離本創作的原理的前提下,所屬領域具通常知識者可以對相關技術特徵作出等同的更改或替換,這些更改或替換之後的技術方案都將落入本創作的保護範圍之內。
