(Current Sensor Anomaly)\u003cbr\u003e\u003cbr\u003eThis problem exists when the inverter is used, because the current direction is uncertain,\u003cbr\u003eThe alarm will be displayed. It does not affect the normal use of BMS.\u003cbr\u003eThis kind of alarm will appear when the sun is not big or small, because at this time,\u003cbr\u003ethe battery fluctuates frequently between charging and discharging,\u003cbr\u003eand there are uncertain factors, so this problem occurs.\u003cbr\u003e\u003cbr\u003eA pure sine wave inverter does not draw a constant current. The current from the battery follows a sine wave shape.\u003cbr\u003eIt ramps from zero current up to peak current in 1\/4 of a cycle.\u003cbr\u003eThe peak current is actually about 40% more than the average current.\u003cbr\u003eThen the current will ramp back down to zero at the 1\/2 cycle time. At this point, the inverter reverses polarity,\u003cbr\u003eand ramps the current back up again, hitting the peak at the 3\/4 cycle time. The battery current is positive again,\u003cbr\u003eand the inversion happens in the inverter circuit. The the current ramps down back to zero again at the end of the cycle.\u003cbr\u003eThe process them repeats for every cycle.\u003cbr\u003e\u003cbr\u003eIf you measure with an averaging meter, you will just see a fairly steady current that should be close to the true RMS current.\u003cbr\u003eI use a True RMS Fluke meter, and it is able to give a vey accurate reading on this odd waveform.\u003cbr\u003eThe current reading in the BMS just measures the voltage across a shunt resistor. This reading is only taken periodically,\u003cbr\u003eand it is not synced the the changing current from the inverter. It might take a reading at zero current, or at the peak current,\u003cbr\u003ebut most likely, it will fall somewhere in between.\u003cbr\u003eDue to the shape of the wave, the reading tends to bounce a bit above and below the true RMS current.\u003cbr\u003eIt is not perfect, but over the long term, it is \"good enough\" for the BMS to calculate the amp hours charged in or discharged out of the battery.\u003cbr\u003eThis works because if you average the readings over a full hour, the high and low readings will average out.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S80c3f54f94b94a96b0ea2472e21bac45J.jpg?width=1000\u0026amp;height=1329\u0026amp;hash=2329\"\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S361ba74fd46944e6bee8390c8e1f163cX.jpg?width=1000\u0026amp;height=1422\u0026amp;hash=2422\"\u003e\u003cimg src=\"https:\/\/ae01.alicdn.com\/kf\/S286f738362fe4b7b92546610d9d63a53A.jpg?width=1000\u0026amp;height=391\u0026amp;hash=1391\"\u003e\u003c\/p\u003e","brand":"hakadibattery","offers":[{"title":"JK 4.3 LCD display","offer_id":48142138474701,"sku":null,"price":32.0,"currency_code":"USD","in_stock":true},{"title":"JK-BD4A8S4P(4-8S 0.4A 40A)","offer_id":47337248817357,"sku":"","price":42.3,"currency_code":"USD","in_stock":true},{"title":"JK-B1A8S10P (4-8S 1A 100A)","offer_id":47337249145037,"sku":"","price":62.45,"currency_code":"USD","in_stock":true},{"title":"JK-B1A8S20P(4-8S 1A 200A)","offer_id":47337249177805,"sku":"","price":63.0,"currency_code":"USD","in_stock":true},{"title":"JK-B2A8S20P(4-8S 2A 200A)","offer_id":47337249210573,"sku":"","price":64.0,"currency_code":"USD","in_stock":true},{"title":"JK-B2A8S30P(4-8S 2A 300A)","offer_id":47337249243341,"sku":"","price":92.45,"currency_code":"USD","in_stock":true},{"title":"JK-BD4A24S4P(8-24S 0.4A 40A)","offer_id":47337248850125,"sku":"","price":47.0,"currency_code":"USD","in_stock":true},{"title":"JK-BD6A24S6P(8-24S 0.6A 60A)","offer_id":47337248882893,"sku":"","price":53.0,"currency_code":"USD","in_stock":true},{"title":"JK-BD6A24S8P(8-24S 0.6A 80A)","offer_id":47337248915661,"sku":"","price":55.0,"currency_code":"USD","in_stock":true},{"title":"JK-BD6A24S10P(8-24S 0.6A 100A)","offer_id":47337248948429,"sku":"","price":60.2,"currency_code":"USD","in_stock":true},{"title":"JK-BD6A24S12P(8-24S 0.6A 120A)","offer_id":47337248981197,"sku":"","price":64.6,"currency_code":"USD","in_stock":true},{"title":"JK-BD6A24S15P(8-24S 0.6A 150A)","offer_id":47337249013965,"sku":"","price":73.85,"currency_code":"USD","in_stock":true},{"title":"JK-B1A24S15P(8-24S 1A 150A)","offer_id":47337249046733,"sku":"","price":92.45,"currency_code":"USD","in_stock":true},{"title":"JK-B2A24S15P(8-24S 2A 150A)","offer_id":47337249079501,"sku":"","price":98.58,"currency_code":"USD","in_stock":true},{"title":"JK-B2A24S20P(8-24S 2A 200A)","offer_id":47337249112269,"sku":"","price":115.58,"currency_code":"USD","in_stock":true},{"title":"JK-B2A24S30P(8-24S 2A 300A)","offer_id":48180022640845,"sku":null,"price":121.3,"currency_code":"USD","in_stock":true},{"title":"JK-PB1A16S10P(8-16S 100A-1A +4.3V19 JK LCD)","offer_id":48079816655053,"sku":null,"price":110.45,"currency_code":"USD","in_stock":true},{"title":"JK-PB1A16S15P(8-16S 150A-1A+4.3V19 JK LCD)","offer_id":48079816687821,"sku":null,"price":115.45,"currency_code":"USD","in_stock":true},{"title":"JK-PB2A16S15P(8-16S 150A-2A+4.3V19 JK LCD)","offer_id":48079816720589,"sku":null,"price":121.2,"currency_code":"USD","in_stock":true},{"title":"JK-PB2A16S20P(8-16S 200A-2A+4.3V19 JK LCD)","offer_id":48079816753357,"sku":null,"price":138.0,"currency_code":"USD","in_stock":true},{"title":"V19-JK-PB2A16S20P(8-16S 200A-2A+4.3V19 JK LCD)","offer_id":48249828737229,"sku":null,"price":139.45,"currency_code":"USD","in_stock":true},{"title":"V19-JK-PB2A16S30P(8-16S 300A-2A+4.3V19 JK LCD)","offer_id":48361263300813,"sku":null,"price":147.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/3694\/2029\/files\/03.jpg?v=1702632693","url":"https:\/\/hakadibattery.com\/pl\/products\/eu-stock-jk-bms-active-balance-bms-4s-8s-12s-16s-20s-24s-smart-bluetooth-bms-60a-80a-100a-150a-200a-for-lifepo4-li-ion-lto-battery","provider":"hakadibattery","version":"1.0","type":"link"}
