據(jù)能源經(jīng)濟(jì)7月8日消息稱，在寶馬(BMW)億萬(wàn)富翁股東斯蒂芬?科萬(wàn)特(Stefan Quandt)的支持下，德國(guó)Solarwatt計(jì)劃推出一個(gè)小型模塊，讓房主可以將屋頂太陽(yáng)能電池板與儲(chǔ)能電池和電動(dòng)汽車連接起來(lái)，以降低成本。
墻箱可以讓房主控制何時(shí)以及儲(chǔ)存多少自家生產(chǎn)的光伏(PV)電力，用來(lái)給電動(dòng)汽車(EV)充電或賣給電網(wǎng)。
此舉針對(duì)的是殼牌(shell)旗下的索能、德國(guó)的E3/DC、EnBW的Senec、LG化學(xué)、Varta和特斯拉，EuPD Research 稱這些公司在家用存儲(chǔ)市場(chǎng)占據(jù)主導(dǎo)地位。
Solarwatt客戶解決方案副總裁Peter Bachmann在計(jì)劃于周三發(fā)布產(chǎn)品前對(duì)路透表示：“能源經(jīng)理是家庭的大腦。”
“它可以智能地分配來(lái)自屋頂?shù)碾娏??！?/p>
Manager Flex 設(shè)備看起來(lái)像一個(gè) wifi 路由器，售價(jià)約為 500 歐元（594 美元），可以將能量流和家里的小玩意整合在一起，比如屋頂面板、電池、電動(dòng)熱泵和電動(dòng)汽車充電盒。
擁有 Solarwatt 大部分股份的 Quandt 上個(gè)月表示：“我們正在展示，我們的DNA中有一種整體的思維方式。”
德國(guó)是一個(gè)明顯的起點(diǎn)。它擁有 30 萬(wàn)個(gè)固定電池，是全球最大的家用存儲(chǔ)市場(chǎng)，領(lǐng)先于美國(guó)、日本和澳大利亞。
自2015年以來(lái)，德國(guó)的電池市場(chǎng)已經(jīng)增長(zhǎng)了10倍，今年預(yù)計(jì)將增長(zhǎng)60%，其動(dòng)力來(lái)自1600萬(wàn)戶家庭，其中200萬(wàn)戶使用太陽(yáng)能電池板。
目前，在德國(guó)，生產(chǎn)一千瓦時(shí)太陽(yáng)能的成本為7歐分，占電網(wǎng)電力的五分之一。
一個(gè)家庭安裝電池板發(fā)電，用電動(dòng)熱泵代替燃油或燃?xì)忮仩t，用電動(dòng)車代替汽油汽車，可以減少89%的二氧化碳排放。

Solarwatt flexes muscles in home energy storage fight with Shell, Tesla
Germany's Solarwatt, backed by BMW's billionaire shareholder Stefan Quandt, plans to launch a small module that lets homeowners link rooftop solar panels to power storage batteries and electric vehicles to cut costs.
The wall box allows homeowners to control when and how much home-produced photovoltaics (PV) power they store, use to charge their electric vehicles (EVs) or sell to the grid.
The move takes aim at Shell-owned Sonnen, Germany's E3/DC, EnBW's Senec, LG Chem, Varta and Tesla, which EuPD Research says dominate the home storage market.
"The energy manager is the brain of the home," Peter Bachmann, Solarwatt's Vice President Customer Solutions, told Reuters ahead of a launch planned for Wednesday.
"It distributes the power from the roof intelligently."
The Manager Flex device, which looks like a wifi router and will go on sale at around 500 euros ($594), allows the integration of energy flows and gadgets at home, such as rooftop panels, batteries, electric heat pumps and EV-charging boxes.
"We are showing that we have a holistic way of thinking in our DNA," Quandt, who owns a majority of Solarwatt, said last month.
Germany is an obvious starting point. With 300,000 stationary batteries, it is the world's top home storage market, ahead of the United States, Japan and Australia.
Germany's battery market has grown tenfold since 2015 and is set for 60% growth this year, fuelled by its 16 million house owners, of which two million operate solar panels.
Currently, it costs 7 euro cents to produce a kilowatt-hour (kWh) of solar power in Germany, a fifth of grid power.
A household installing panels for generation, an electric heat pump to replace oil or gas boilers, and buying an EV instead of a petrol-based car can cut its CO2 emissions by 89%, it said.
