1、極簡(jiǎn)：5G電源需要遵循極簡(jiǎn)的設(shè)計(jì)理念，5G電源創(chuàng)新解決方案實(shí)現(xiàn)少占空間、簡(jiǎn)易安裝、快速部署和簡(jiǎn)單運(yùn)維。 2、智能：5G電源基于Bit管理Watt的理念，應(yīng)用AI與Cloud技術(shù)實(shí)現(xiàn)電源與站點(diǎn)設(shè)備、電源與網(wǎng)絡(luò)設(shè)備多層次的智能協(xié)同，電源從“功能機(jī)”演進(jìn)到“智能機(jī)”，支撐站點(diǎn)的CAPEX和OPEX大幅降低。同時(shí)站點(diǎn)運(yùn)維也需要從傳統(tǒng)人工運(yùn)維走向更有效的智能運(yùn)維。 3、有效：區(qū)別于傳統(tǒng)基于單部件節(jié)能的設(shè)計(jì)，5G電源需要從供電、轉(zhuǎn)換、備電、配電、溫控和負(fù)載環(huán)節(jié)進(jìn)行端到端的全鏈路有效設(shè)計(jì)。同時(shí)在供電環(huán)節(jié)，支持各類新能源接入，支撐綠色節(jié)能，實(shí)現(xiàn)0比特0瓦特的目標(biāo)。</p><p style="text-indent:25px">5G基站電源，市場(chǎng)空間多大？不可否認(rèn)，5G通信電源目前是一個(gè)藍(lán)海市場(chǎng)。目前，5G單站供電功率預(yù)計(jì)將達(dá)到約4000瓦甚至更高，因而基站電源存在極大的擴(kuò)容需求。換言之，90%的4G存量電源均需擴(kuò)容和改造，以滿足5G使用需求。那么，通信電源市場(chǎng)前景究竟有多誘人，安信證券對(duì)5G電源市場(chǎng)空間的測(cè)算可見一斑：（1）若在現(xiàn)有的-48V開關(guān)電源方案基礎(chǔ)上擴(kuò)容，按照5G基站近4000瓦的輸入功率需求測(cè)算，至少需要增加2個(gè)-48V/50A的整流模塊，假設(shè)以2000元/個(gè)的模塊單價(jià)，則單站的擴(kuò)容成本為4000元。（2）若采用HVDC直流遠(yuǎn)供或者DPS分布式供電，單站價(jià)值約在7000-1萬(wàn)元左右。進(jìn)一步假設(shè)3種供電方案的建設(shè)比例為1：1：1，那么按照國(guó)內(nèi)450萬(wàn)站的建設(shè)規(guī)模測(cè)算，預(yù)計(jì)5G基站電源市場(chǎng)空間有望達(dá)到315億元。5G通信時(shí)代下UPS電源+鋰電池的應(yīng)用。</p><div
