Bentenane voltase sing seimbang nuduhake yen sel diisi kanthi padha, njamin maca SOC sing akurat. Bedane, prabédan voltase sing ora seimbang bisa nyebabake maca SOC sing ora akurat, sing nyebabake perkiraan kapasitas baterei sing ora bisa dipercaya. Nalika sel disambungake kanthi seri, prabédan voltase ing antarane sel kasebut cenderung saya tambah suwe amarga variasi karakteristik sel lan efek penuaan. Ketidakseimbangan voltase iki bisa nyebabake ngisi daya sing berlebihan utawa kurang daya sel, sing bisa nyebabake karusakan sing ora bisa dibaleni maneh lan nyuda umure.Kanggo ngatasi masalah iki, sistem manajemen baterei (BMS) digunakake ing paket baterei lithium. BMS ngawasi lan ngontrol beda voltase antarane sel, mesthekake yen iku tetep ing sawetara aman. Iki bisa ditindakake kanthi ngimbangi pangisian daya ing antarane sel, kanthi nyebarake energi utawa mbatesi pangisi daya sel kanthi voltase sing luwih dhuwur. Balancing aktif iki mbantu kanggo njaga prabédan voltase imbang lan ngluwihi umur sakabèhé saka Pack baterei.

Kesimpulane, ngerteni pentinge bedane voltase sel baterei lithium iku penting kanggo ngoptimalake kinerja, efisiensi, lan umure paket baterei. A prabédan voltase imbang mesthekake yen saben sel nyumbang merata kanggo voltase total Pack, ngoptimalake output daya. Iki uga mbantu maca SOC sing akurat lan perkiraan kapasitas baterei sing dipercaya. Kajaba iku, njaga prabédan voltase sing seimbang penting kanggo umur dawa baterei, amarga prabédan voltase sing ora seimbang bisa nyebabake karusakan sel lan umure suda. Sistem manajemen baterei nduweni peran penting kanggo njaga prabédan voltase sing seimbang kanthi aktif ngimbangi daya ing antarane sel. Kanthi nimbang lan ngatur prabédan voltase, kita bisa njamin fungsi optimal lan umur dawa paket baterei lithium ing macem-macem aplikasi.In conclusion, understanding the importance of lithium battery cell voltage difference is crucial for maximizing the performance, efficiency, and lifespan of battery packs. A balanced voltage difference ensures that each cell contributes equally to the pack’s total voltage, optimizing power output. It also helps in accurate SOC readings and reliable battery capacity estimations. Moreover, maintaining a balanced voltage difference is essential for the longevity of the battery pack, as an imbalanced voltage difference can lead to cell damage and reduced lifespan. Battery management systems play a vital role in maintaining a balanced voltage difference by actively balancing the charge among cells. By considering and managing the voltage difference, we can ensure the optimal functioning and longevity of lithium battery packs in various applications.
