Power system a lo thang zel chuan grid scale chu a zau zel a, hei hian power communication mamawhna sang zawk a thlen a ni. Battery te hian telecom power system-a thil pawimawh tak angin power communication rintlaknaah nghawng a nei nghal vek a ni. Charge leh discharge cycle hmanga capacity testing neih hi battery performance vawn thatna tur leh battery life tihzauh nan a pawimawh hle. Telecom power system enkawlna tur dan siam dan chuan battery hi enkawl reng a ngai a ni. Terminal voltage tehna leh internal resistance testing ang chi method nena khaikhin chuan capacity testing hian a dik zawk a ni. Battery dah thar hian full-capacity discharge test a ngai a, chumi hnuah kum tin capacity discharge test a ngai bawk. Kum li chhung battery hman mek tan chuan semi-annual capacity testing neih a ngai a ni. Battery pakhatin test vawi thum a zawna a rate 80% a neih theih loh chuan a thlakna tur ngaihtuah tur a ni.
Tunah hian common battery capacity testing scheme pathum chu engineering-ah hman a ni nasa hle a, chungte chu dummy load, DC/AC conversion, leh DC/DC boosted voltage scheme te an ni.
Capacity testing device hi a bul berah chuan high-frequency DC/DC battery pack boosted circuit module, high-frequency DC/DC battery pack constant current charge module, contactors, leh diode te a ni. He system hi state pathum-ah a thawk a, chungte chu standby floating charge, capacity discharge, leh constant current charge te an ni. Heng state te hian capacity testing atan operational cycle kimchang tak an siam a ni.
Standby a ni a, a chungah hian a awm a ni.
Floating charge state-ah chuan NC contactor K1 chu khar a ni a, no contactor km a inhawng a ni. Battery hi online a ni a, rectifier hian battery pack leh load pahnih ah power a pe vek a ni. Beisei loh taka power a tlak loh chuan battery pack hian load-ah power direct-in a supply thei a, hei hian power supply tihtawp loh a tichiang thei a ni.
Figure 1: Battery pack chu standby floating charge state ah a awm a.
Capacity discharge state 1.1.
Capacity discharge lai hian NC contactor K1 a inhawng a, no contactors KM leh KC close te a inhawng bawk. High-frequency DC/DC battery pack boosted circuit hian hna a thawk thei a ni. Battery chu DC/DC circuit hmangin voltage-ah rectifier voltage aiin a sang deuh hlek a, chu chuan rectifier chu load-a power supply-naah a thlak a ni. Discharge zawh chuan system chu constant current charging-ah a inthlak nghal a, constant current charge circuit module a thawk a ni.
Figure 2: Battery pack chu a awm theihna tur discharge state a ni.
Tuna charge awm mek state .
Capacity discharge hnuah system chu constant current charging-ah a inthlak nghal vek a ni. High-frequency DC/DC Battery Pack Constant Current Charge Circuit Module hian hna a thawk a, constant current charging atan original rectifier hmangin charge current chu set value-ah a siamrem nghal vek a ni. Battery voltage chu charging process tawp lam a nih chuan charging current a tlahniam zel a. Current chu device set threshold hnuaiah a tlak chuan system chuan constant current charge process chu a titawp nghal vek a ni. NC contactor K1 chu khar a ni a, high-frequency DC/DC Battery Pack awm mek chu charge circuit module awm reng a ni a, KM leh KC te chu a inzawm lo. Chumi hnuah chuan battery pack chu standby floating charge state-ah a kir leh a.

A chunga kan sawi tak hian DC/DC hmanga capacity testing system kalpui dan tur a sawi a. He solution hi industry siamtute chuan an hmang nasa hle a ni. Entirnan, DFUN chuan remote online capacity testing solution kimchang tak a design a, chu chuan dispersed site-te chu hla tak atangin centralized control a nei thei a, chu chu hun tikhawtlai thei, remchang leh rintlak a ni.
DFUN Capacity Testing Solution , capacity testing function bakah hian real-time battery monitoring leh battery activation features te a awm a, remote, round-the-clock monitoring leh battery pack te enkawl theihna a awm bawk.
