Tunah hian sumdawnna leh industry lama energy dahkhawmna hi a lar hle a, mahse hmun dik thlan erawh a pawimawh hle. Peak-valley man inthlauhna 0.7 RMB/kWh aia tam awmna bial, Guangdong, Zhejiang, leh Jiangsu-ah te chuan sumdawnna leh industry lama energy khawlkhawm hi a awm thei a ni. Zhejiang hi entirnan la ila, sumdawnna leh industry lama hmanna atana peak-valley price difference chu a tlangpuiin 0.8-0.9 RMB a ni a, load curve tling tak a awm chuan payback period hi kum 5-6 vel a ni thei. Mahse, peak-valley man inthlauhna tlem zawk awmna hmun, Henan leh Shandong-ah chuan economics hi a kal thei lo.

Energy thar chhuahna atana energy dahkhawmna tur (mandatory energy storage allocation) chu, thudik tak sawi ila, tunah hian policy-driven a ni a, a economic viability pawh a tlangpuiin a hniam hle. Allocation ratio 10%-20% leh hman hun chhung darkar 2 a nih chuan kum khata hman hun chhung chu darkar za thum atanga za li chauh a ni thei a, hei vang hian hlawkna hmuh a harsa hle. Mahse, hei hi grid connection atana threshold a ni a, kawng dang a awm lo.

China Chemical and Physical Power Sources Industry Association data atanga a lan dan chuan kum 2023 khan China ramah hian energy storage project thar 20GW/40GWh chuang hman tan a ni a, 80% chuangin containerized solution an hmang a ni. He proportion ngei pawh hian market duhthlanna a lantir a ni.

Tunah chuan liquid cooling hi energy storage project lian tak takah chuan standard practice a ni tawh a ni.

Liquid cooling chungchanga inhnialna chu a tam zawk chu a tawp tawh. Kum hnih kalta khan miten air cooling nge liquid cooling hi a tha zawk tih an inhnial nasa hle a; tunah chuan inhnialna chu practically a tawp ta. A chhan chu a awlsam hle: battery cell capacity a sang chho zel (280Ah atanga 314Ah-ah, tunah chuan 560Ah chu mass production-ah a awm tawh), energy density a sang chho zel a, heat generation pawh a sang chho zel bawk. Air cooling hian a zui thei lo mai mai.

Liquid cooling hlawkna chu direct a ni:

Dik tak chuan liquid cooling hian a chhiatna a nei bawk-a man to, system complexity, leh leakage hlauhawmna te. Mahse, thil zawng zawng ngaihtuah chuan, 3MWh emaw a aia tam emaw container lian-capacity tan chuan liquid cooling hlawkna hian a senso aiin a tam zawk a ni.

CATL-in kum 2024-a an tihchhuah Tianheng energy storage system hian liquid cooling technology hmasawn tak hmangin feet 20-a sei container pakhatah 6.25MWh a pe thei a ni. He energy density hi kum thum kalta khan ngaihtuah phak loh a ni.

Containerized Energy Storage lama Trend engemaw zat

Trend 1: Capacity lian zawk lam hawia kal zel tur a ni.

Foot 20-a sei battery case chu 2MWh aṭangin 3.5MWh-ah a pung a, chumi hnuah 5MWh-ah a pung a, tunah chuan company lar tak takte chuan 6MWh+ product-te chu an nawr chho ta a ni. Feet 40-a sei case-a 10MWh neih chu thil theih loh a ni lo.

Trend 2: Technological "involution" chu cell atanga system ah a inthlak chho zel a.

Cell segment hi homogenized sang tak a ni tawh a, lithium iron phosphate battery supplier lar tlemte chauh an awm. Nakin lawka differentiated competition hian system integration theihna-thermal management, safety design, intelligent operation leh maintenance, leh full lifecycle cost optimization te a ngaih pawimawh zawk dawn a ni.

Trend 3: Sodium battery hi market-ah a lut dawn a, mahse order awmsa chu a tibuai dawn lo.

Sodium-ion battery hi a man tlawm zawk tak zet a, low-temperature performance tha zawk a nei bawk. Mahse, tunah chuan an energy density leh cycle life hi lithium iron phosphate aiin a hniam zawk a ni. Ka ngaihdan chuan sodium battery hian energy density mamawh hniam zawk (hmarchhak biala peak-shaving energy storage ang chi) cost-sensitive scenario-ah market share engemaw zat a nei ang a, mahse kum thum atanga kum nga chhungin lithium battery-te dinhmun thunun ber chu a tichhe dawn lo.

Trend 4: Operation leh maintenance chu "human wave" approach atanga intelligent systems ah a inthlak dawn a ni.

Tunah hian energy storage power station tam tak chu kut hmanga enfiahna (manual inspection)-ah an la innghat a, hei hi a hlawk lo va, a man pawh a to hle. Nakin lawkah chuan digital twins, AI diagnostics, leh predictive maintenance hmangin operation leh maintenance model-ah hian inthlak danglamna bulpui tak a awm dawn a ni. Company thenkhat chuan he lam hi an dap tawh a, result duhawm tak an nei.
