Pane zvakanakira nezvayakaipira zvakabatana neaya maviri makuru bhatiri chemistry anoshandiswa mu solar + kuchengetedza mapurojekiti.Mabhatiri e-lead-asidhi avepo kwenguva yakareba uye ari kunzwisiswa zviri nyore asi ane miganhu yekukwanisa kwawo kuchengetedza.Lithium-ion bhatiris vane hupenyu hwakareba uye vane huremu hwakareruka asi vachigara vachidhura.

Kuisirwa kwekuchengetedza kunowanzo kuve nemhando yebhatiri imwe chete, senge LG Chem, pano.Mufananidzo nerubatsiro rweGreenBrilliance

Munhu anogona here kusanganisa zvakanakira makemikari ega ega kuti aite bhangi risingadhure, rinokwanisa bhatiri repamusoro?

Mumwe anoenda kunobvisa lead-asidi bhatiri bhangi ravo kuti vangopinda mumabasa ebhatiri idzva relithium-ion?Munhu anogona here kuwedzera mabhatiri e-lead-asidhi akachipa kune yavo lithium system kuti asangane neimwe kilowatt-awa kugona?

Mibvunzo yese yakakosha ine mhinduro isina kutsanangurwa: zvinoenderana.Zviri nyore uye zvishoma zvine njodzi kuramba uine chemistry imwe, asi kune mamwe mabasa akatenderedza.

Gordon Gunn, injiniya wemagetsi paFreedom Solar Power muTexas, akati zvinokwanisika kubatanidza lead-asidhi uye lithium mabhatiri pamwe chete, asi chete kuburikidza ne AC coupling.

"Iwe haugone zvachose kubatanidza lead-asidhi uye lithium mabhatiri mubhazi rimwe chete reDC," akadaro.“Pazvakanakisa, zvinoparadza mabhatiri, uye zvakaipisisa…moto?Kuputika?Kuverenga kwenzvimbo-yenguva inoenderera?Handizive."

K. Fred Wehmeyer, mukuru VP weinjiniya pakambani yebhatiri ye-lead-acid US Battery Manufacturing Co., akapa imwe tsananguro.

"Inogona kugadzirwa, asi zvaisazove nyore sekungowedzera mabhatiri e-lead-asidhi kune lithium bhatiri system.Masisitimu maviri aya angangove achiita akazvimirira," Wehmeyer akadaro.“Lithium battery system inenge ichiri kudiwa kuti idzorwe neBMS yayo ine charger yayo nechaji controller.Iyo lead-acid bhatiri system yaizoda yayo pachaja uye/kana yekuchaja controller asi yaisazoda BMS.Masisitimu maviri aya anogona kunge achipa mitoro yakaenzana nenzira yakafanana asi panogona kuve nekutonga kugovera zvakachengetedzeka kugovera mitoro pakati pemakemikari maviri. "

Troy Daniels, tekinoroji masevhisi maneja weLFP bhatiri inogadzira SimpliPhi Power, haakurudzire kusanganisa yakafanana bhatiri chemistry rega kusiyanisa chemistry mune imwechete system, asi anobvuma kuti inogona kuitwa.

"Nzira dzinoverengeka dzekubatanidza ingave nzira yekuve nemasisitimu maviri ega (ese machaja uye inverter) anogona kugovera mutoro wakafanana kana kupatsanura zvinodikanwa zvemagetsi." akati.“Switch yekufambisa inogona kushandiswawo;zvisinei, izvi zvingangoreva seti imwe chete yemabhatiri kana kemisitiri inogona kuchaja kana kuburitsa panguva uye ingangove yekuchinjisa nemaoko.

Kupatsanura mitoro uye kumisikidza masisitimu maviri kazhinji ibasa rakaoma kupfuura iro vazhinji vanoda kukwira.

"Hatina kubata neiyo hybrid lithium/lead-acid system kuFreedom Solar nekuti haingave yakachipa yekuwedzera, uye tinoedza kuchengetedza mabhatiri edu ari nyore nekushandisa chete bhatiri chemistry uye chimwe chigadzirwa chebhatiri, ” akadaro Josh Meade, PE uye maneja wedhizaini.

Pane imwe kambani iri kuyedza kuita kuti kusanganisa maviri chemistry kuve nyore.Inotakurika magetsi chigadzirwa inogadzira Goal Zero ine lithium-yakavakirwa Yeti Inotakurika Power Station iyo inogona kushandiswa kune chikamu chekuchengetedza imba.Yeti 3000 ndeye 3-kWh, 70-lb NMC lithium bhatiri inogona kutsigira maseketi mana.Kana simba rakawanda richidikanwa, Goal Zero inopa yayo Yeti Link Kuwedzera Module iyo inobvumira kuwedzera kwelead-asidhi yekuwedzera mabhatiri.Hongu, ndizvozvo: Iyo lithium Yeti bhatiri inogona kupetwa nelead-asidhi.

“Tangi redu rekuwedzera idenderedzwa risinganzwisisike, lead-acid bhatiri.Izvi zvinokubvumira kushandisa magetsi muYeti [lithium-based system] asi inowedzera bhatiri, "akadaro Bill Harmon, GM paGoal Zero.“Pa1.25-kWh imwe neimwe, unogona kuwedzera akawanda [mabhatiri eeasidhi] sezvaunoda.Mutengi anogona kungoaisa mukati. Kamwe kamwe unowana kutakurika kwebhatiri relithium uye mabhatiri elead-asidhi asingadhure akagara pamba.”

Matambudziko makuru kana uchiedza kubatanidza lithium uye lead-asidhi pamwe chete iwo akasiyana voltages, kuchaja profiles uye kuchaja/kuburitsa miganho.Kana mabhatiri ari kunze kwemagetsi akafanana kana kuti ari kuburitsa pamitengo isingaenderane, simba rinomhanya nekukurumidza pakati peumwe neumwe.Kana simba richimhanya nekukasira, nyaya dzekudziya dzinomuka uye dzinowedzera kushanda kwebhatiri kutenderera.

Goal Zero inogadzirisa mamiriro aya neiyo Yeti Link mudziyo.Yeti Link inonyanya kugadzirwa kwebhatiri manejimendi system inokodzera yekutanga Yeti lithium bhatiri iyo inokwenenzvera voltages uye kuchaja pakati pemakemikari akasiyana.

"Yeti Link iri kudzora kufambisa kwesimba pakati pemabhatiri.” Harmon akadaro."Isu tinodzivirira nenzira yakachengeteka, kuitira kuti lithium bhatiri isatomboziva kuti yakaroora nebhatiri re-lead-acid."

Iyo Yeti 3000 inogona kunge idiki pane yechinyakare lithium mabhatiri epamba - LG Chem.Tesla nemasonnet modhi anowanzo aine angangoita 9.8 kWh yesimba - asi ndiko kudhirowa kwayo, Harmon akadaro.Uye kana mumwe munhu achikwanisa kuiwedzera kusvika kune iyo 9-kWh mamaki aine mamwe mabhatiri ekutungamira akachipa uye zvakare kutora bhatiri relithium naro paunenge uchidzika musasa kana kumonereka, wadii?

“Sitimu yedu ndeyevanhu vese munyika vasina $15 000 yekuisa mari mukugadzira magetsi.Uye kana ndapedza, ndinongofanirwa kuve chimwe chinhu chakaiswa zvachose mumba mangu, ”Harmon akadaro."Yeti ndeyeavo vari panjodzi kune izvo zvavari kushandisa mari pazviri.Sisitimu yedu i$3,500 yakazara yakaiswa."

Chinangwa Zero chave pachizvarwa chechishanu chechigadzirwa, saka ine chivimbo mukugona kwayo kwe lithium-lead musanganiswa.Asi kune vamwe vazhinji vasina kugadzikana kusanganisa kemikari yebhatiri zvachose, masisitimu maviri akazvimirira uye akazvimirira anogona kuiswa mubhizinesi rimwechete kana imba - chero bedzi akamiswa nenyanzvi yemagetsi.

"Nzira yakapfava uye yakachengeteka yekuwedzera yakaderera-mutengo yekuchengetedza kune iripo lithium system ingave yekukamura mitoro nekuigovera zvakasiyana kune maviri mabhatiri masisitimu.” US Battery's Wehmeyer akadaro.“Chero nzira.Zvinofanirwa kuitwa nenyanzvi yakadzidziswa kuchengetedza kuchengeteka.
