| Amashaja wamathuluzi wamandla angenazintambo asebenza ngokusebenzisa ugesi ophuma kumapayipi amakhulu kanye nokushaja ibhethri elilahliwe. |
 | Isayensi yamabhethri aphinde ashajwe nokuthi amashaja angashaja kanjani ibhethri kuxoxwa ngawo ekhasini Lisebenza kanjani ibhethri lethuluzi lamandla angenazintambo? Lapha sibheka ukuthi amashaja ahlinzeka kanjani ngokushaja okugcwele nangempumelelo futhi avimbele ukulimala kwebhethri. |
| Amashaja angcono kakhulu asebenzisa lokho okubizwa ngokuthi ishaja yezigaba ezintathu noma ishaja enezigaba eziningi. Amashaja ebhethri asekelwe ku-nickel kanye ne-lithium asebenzisa isistimu enezigaba ezintathu, nakuba esebenza ngokuhlukile kancane. |
Ukushaja okuyizigaba ezi-3 |
| Izigaba ezintathu zibizwa ngokuthi "inqwaba", "ukumuncwa" kanye "nokuntanta". Amanye amashaja asebenzisa isistimu enezigaba ezimbili enezigaba eziningi kuphela nezintantayo; lamashaja ayashesha kodwa awanakekeli kangako ibhethri. |
| Phakathi nesigaba sokugcwalisa, ibhethri lishajwa kumthamo olinganiselwa ku-80%. Amandla kagesi ahlala ezingeni elifanayo, kodwa i-voltage (ingcindezi kagesi) ehlinzekwa yishaja iyakhula. |
| Isigaba sokumunca yilapho i-voltage ibanjwe ezingeni elifanayo futhi yamanje inhla kancane kuze kube yilapho ibhethri selishajwe ngokugcwele. Kwaziwa nangokuthi "i-top-up charge" ngoba ishaja kabusha ibhethri yokugcina. Lokhu kuthatha isikhathi eside kakhulu kunesiteji sobuningi ngoba kufanele sihambe kancane ukuvikela ukulimala kwebhethri. |
| Isiteji esintantayo samashaja ebhethri e-NiCd kanye ne-NiMH, esaziwa nangokuthi "i-drip charge", yilapho i-voltage kanye namanje kwehliswa kuze kufike ezingeni eliphansi kakhulu. Lokhu kugcina ibhethri ligcwaliswe ngokugcwele kuze kudingeke. |
| Amabhethri e-NiMH adinga ukushajwa okuqhubekayo okuphansi kakhulu kunamabhethri e-NiCd, okusho ukuthi awakwazi ukushajwa kabusha ngeshaja eqondene ne-NiCd. Nokho, amabhethri e-nickel-cadmium angashajwa kushaja yebhethri ye-nickel-metal hydride, nakuba lokhu kungalungile. |
| Isiteji esintantayo samashaja ebhethri e-lithium-ion asishayi ngokuqhubekayo. Kunalokho, ama-pulses eshaja agcina ibhethri lishajwe ukuze limelane nokuzikhipha ngokwawo. Ukushaja kabusha kungase kushaje ibhethri le-lithium futhi kulilimaze. |
Ukutholwa kwebhethri okugcwele |
| Amashaja ashibhile anquma ukuthi ibhethri le-nickel-cadmium lishajwa nini ngokugada izinga lokushisa lebhethri. Lokhu akunembile ngokwanele futhi kungalimaza ibhethri ngokuhamba kwesikhathi. |
| Amashaja e-NiCd athuthuke kakhulu asebenzisa ubuchwepheshe be-Negative Delta V (NDV), obuthola ukwehla kwamandla kagesi okwenzeka lapho ibhethri selishajwe ngokugcwele. Kuthembeke kakhulu. |
| Amashaja ebhethri e-NiMH kufanele asebenzise inhlanganisela yezinzwa ukuze anqume ukuthi ibhethri ishajwe nini ngokugcwele ngenxa yokuthi ukwehla kwamandla kagesi akukukhulu ngokwanele ukuze kubonakale ngokunembile. |
| Amashaja ebhethri e-lithium-ion ane-chip yekhompyutha eyinkimbinkimbi egcina umkhondo wezinguquko zeseli. Amabhethri e-lithium-ion antekenteke kakhulu futhi adinga izindlela zokuthola ezinembe ukuze avikeleke emonakalweni. |
