Battery chhunga resistance hi battery hriselna leh service life tehna atana thil pawimawh tak a ni. Hun kal zelah internal resistance a pung zauh zauh a, performance a nghawng tha lo hle. Hei hian discharge rate a ti hniam thei a, energy hloh a ti sang thei a, operating temperature a tisang thei bawk. A bik takin, internal resistance chu normal value atanga 25% aia tam a nih chuan battery capacity a tlahniam nasa hle a, system stability a tichhe thin. Chuvangin battery chhunga resistance awm dan chu real-time dynamic monitoring neih a pawimawh hle.
1. Direct Current (DC) hmanga paih chhuah dan
Hetiang method hian battery chu current sang tak hmanga discharge a, voltage drop atanga internal resistance chhut a ni. Measurement accuracy sang tak a pek rualin battery chhungah polarization reaction a siam a, aging a ti chak hle. Chuvang chuan he method hi research leh pilot production phase-ah hman a ni ber a, hun rei tak chhunga enkawlna atan a tha lo hle.
2. Alternating Current (AC) Impedance hman dan tur
Frequency bik alternating current hmanga Ohm’s Law leh capacitance principle te hmang tangkaiin he method hian internal resistance a teh a ni. DC discharge method ang lo takin AC impedance method hian battery life a tichhe lo va, frequency-a innghat lo zawk result a pe bawk. Frequency 1kHz-a tehna lak hi a tlangpuiin a nghet ber. Hetiang method hi industry-ah hman a ni nasa hle a, accuracy sang tak a nei a, margin of error chu 1% leh 2% inkar a ni.
DFUN hian AC impedance method hmanlai—AC Low Current Discharge Method—a siam thatna thar a siam chhuak a ni. Alternating current 2A aia tam lo hman a, voltage inthlak danglamna chiang taka tehna hmang hian battery chhunga resistance chu hun rei lote chhung (second khat vel) chhungin dik takin chhut theih a ni.
A thatna pawimawh tak tak:
High Accuracy: Measurement accuracy hi 1% vel a ni a, third-party brand Hioki leh Fluke te result nen a inang tlang hle.
Chhungril lama Dodalna |
2V Battery: 0.1 ~ 50 mΩ a ni |
A tih nawn leh theihna: ±(1.0% + 25 μΩ) |
A chhuahna tur hmun: 0.001 mΩ |
12V Battery: 0.1 ~ 100 mΩ a ni |
Battery hriselnaah nghawng a nei lo: Current hniam leh discharge amplitude tlem ber a nih chuan he method hian battery a tichhe lo va, a tar chak lo bawk.
Real-Time Monitoring: Battery status real-time-a hmuh theihna a siam a, internal resistance tihpun avanga performance tihchhiat a veng tha hle.
Versatile Application: He technology hi lead-acid battery-ah chauh hman theih a ni lo va, battery chi dang hrang hranga internal resistance enfiahna atan pawh a tangkai hle.
I battery te chu a tha ber tura enkawl la, i power system te stability leh rintlakna a ti sang ang.
