Isishwankathelo:

Ngomhla wama-21 kuJuni, ngo-2022, iwebhusayithi yoMphathiswa weZindlu waseTshayina noPhuhliso lwaseziDolophini-maPhandle yakhuphaIKhowudi yoYilo yeSikhululo sokuGcinwa kwaMandla e-Electrochemical (Idrafti yamagqabaza). Le khowudi yabhalwa yiChina Southern Power Grid Peak kunye neFrequency Regulation Power Generation Co.,Ltd. kwakunye nezinye iinkampani, eziququzelelwa nguMphathiswa weZindlu noPhuhliso lweDolophu-maPhandle. Umgangatho ujonge ukusetyenziswa kuyilo lwesikhululo esitsha, esandisiweyo okanye esilungisiweyo esimileyo sokugcina amandla e-electrochemical esinamandla angama-500kW kunye nomthamo wama-500kW·h nangaphezulu. Ngumgangatho wesizwe osisinyanzelo. Umhla wokugqibela wezimvo nguJulayi 17, 2022.

Iimfuno zeebhetri zeLithium:

Umgangatho uncoma ukusebenzisa i-lead-acid (lead-carbon) iibhetri, iibhetri ze-lithium-ion kunye neebhetri zokuhamba. Kwiibhetri ze-lithium, iimfuno zimi ngolu hlobo lulandelayo (ngokwezithintelo zokujonga le nguqulo, kuphela iimfuno eziphambili zidweliswe):

1. Iimfuno zobuchwepheshe zeebhetri ze-lithium-ion ziya kuhambelana nomgangatho wangoku welizweIibhetri zeLithium-ion ezisetyenziswa kuGcino lwaMandlaI-GB / T 36276 kunye nomgangatho wangoku wamashishiniIiNkcazo zobuGcisa kwiiBatri zeLithium-ion ezisetyenziswa kwiSikhululo sokuGcina saMandla e-ElectrochemicalNB/T 42091-2016.

2. I-voltage elinganisiweyo yeemodyuli zebhetri ye-lithium-ion kufuneka ibe yi-38.4V, 48V, 51.2V, 64V, 128V, 153.6V, 166.4V, njl.

3. Iimfuno zobuchwepheshe zenkqubo yokulawula ibhetri ye-lithium-ion kufuneka ihambelane nomgangatho wangoku welizweIiNkcazo zobuGcisa kwiiBatri zeLithium-ion ezisetyenziswa kwiSikhululo sokuGcina saMandla e-ElectrochemicalGB / T 34131.

4. Imo yeqela kunye ne-topology yoqhagamshelo lwenkqubo yebhetri kufuneka ihambelane nesakhiwo se-topology somguquli wokugcina amandla, kwaye kuyinqweneleka ukunciphisa inani leebhetri eziqhagamshelwe ngokufanayo.

5. Inkqubo yebhetri kufuneka ixhotyiswe nge-DC, i-switch switches kunye nezinye izixhobo zokuqhawula kunye nokukhusela.

6. I-voltage yecala le-DC kufuneka imiselwe ngokweempawu zebhetri, inqanaba lokumelana nombane, ukusebenza kwe-insulation, kwaye akufanele ibe phezulu kune-2kV.

Ingxelo yoMhleli:

Lo mgangatho usaphantsi kokubonisana, amaxwebhu ahambelanayo anokufumaneka kwiwebhusayithi elandelayo. Njengomgangatho onyanzelekileyo wesizwe, iimfuno ziya kuba yimfuneko, ukuba awukwazi ukuhlangabezana neemfuno zalo mgangatho, ukufakwa kamva, ukwamkelwa kuya kuchaphazeleka. Kucetyiswa ukuba iinkampani kufuneka ziqhelane neemfuno zomgangatho, ukuze iimfuno zomgangatho ziqwalaselwe kwinqanaba loyilo lwemveliso ukunciphisa ukulungiswa kwemveliso kamva.

Kulo nyaka, i-China iye yazisa kwaye ihlaziywa inani lemimiselo kunye nemigangatho yokugcina amandla, njengokuhlaziywa kwe-GB / T 36276 umgangatho, iiMfuno eziPhambili ezingamashumi amabini anesihlanu zokuThintela iiNgozi zoMveliso woMbane (2022) (idrafti yokuphawula) (jonga ngezantsi ngeenkcukacha), Ukuphunyezwa koPhuhliso loGcino lwaMandla oMtsha kwiSicwangciso seMinyaka emiHlanu ye-14, njl.njl. Le migangatho, imigaqo-nkqubo, imimiselo ibonisa indima ebalulekileyo yamandla. ukugcinwa kwinkqubo yamandla, ngelixa libonisa ukuba kukho ukungafezeki okuninzi kwinkqubo yokugcina amandla, njenge-electrochemical (ingakumbi ibhetri ye-lithium) yokugcina amandla, kwaye i-China iya kuqhubeka nokugxila kwezi ziphene.
