BYD forklift BMS abnormal na komunikasyon orihinal na wiring harness at plano sa pagpapalit ng mga bahagi ng baterya(larawan1)

Ang BMS ay ang core ng sistema ng pamamahala ng baterya ng electric forklift. Kapag nagkaroon ng abnormal na komunikasyon, mabibigo ang pagsubaybay sa status ng baterya, magiging hindi matatag ang power output, at ma-trigger pa ang mekanismo ng proteksyon sa kaligtasan upang ihinto ang forklift, na makakaapekto sa kahusayan sa pagpapatakbo at kaligtasan ng kagamitan. Kapag nakakaranas ng mga ganitong problema, ang pagkabigo ng orihinal na wiring harness at mga accessory ng baterya ay isang karaniwang sanhi, at kinakailangang sundin ang standardized na proseso para sa inspeksyon at pagpapalit.

Ang una ay ang lohika ng pag-troubleshoot: suriin muna kung may mga palatandaan ng pinsala o baluktot sa hitsura ng orihinal na wiring harness, kung mayroong anumang pagkaluwag o oksihenasyon sa interface, at gumamit ng mga propesyonal na instrumento upang makita ang on-off ng wiring harness; pagkatapos ay basahin ang fault code sa pamamagitan ng on-board diagnostic system, at suriin ang mga accessory ng baterya. Kung ang module ng komunikasyon at sensor ay may abnormal na paghahatid ng signal, at tumpak na i-lock ang mga may sira na bahagi.

Ang pagpapalit ng orihinal na wiring harness ay dapat sundin ang mga sumusunod na hakbang: ang unang hakbang ay putulin ang pangunahing power supply ng forklift at magsuot ng insulating protective equipment upang matiyak ang ligtas na operasyon; ang pangalawang hakbang ay markahan ang posisyon at paraan ng koneksyon ng bawat wiring harness interface na may label na panulat upang maiwasan ang kasunod na pag-install ng misalignment; Ang ikatlong hakbang ay maingat na alisin ang lumang wiring harness, at mag-ingat na huwag hilahin ang mga nakapaligid na pipeline at mga de-koryenteng bahagi; ang ikaapat na hakbang ay alisin ang orihinal na wiring harness ng parehong detalye, at ikonekta ang mga interface nang paisa-isa ayon sa mga marka upang matiyak na ang mga wiring harness ay nakasaksak nang mahigpit nang walang pagkaluwag; ang ikalimang hakbang ay upang ayusin ang wiring harness At ayusin ito gamit ang isang buckle upang maiwasan ang alitan sa mga gumagalaw na bahagi ng forklift; sa wakas, i-on ang power at simulan ito, at i-verify kung

Ang proseso ng pagpapalit ng mga accessory ng baterya ay ang mga sumusunod: ang unang hakbang ay upang kumpirmahin ang modelo ng mga may sira na accessory, at piliin ang orihinal na mga accessory ng parehong detalye upang matiyak ang pagiging tugma ng system; ang pangalawang hakbang ay upang putulin ang pangunahing supply ng kuryente, at alisin ang mga fixing bolts at mga interface ng linya ng komunikasyon ng mga accessory; ang ikatlong hakbang ay ang pag-install Ang mga bagong orihinal na bahagi ay naayos ayon sa orihinal na mga detalye ng pabrika, at ang linya ng komunikasyon ay muling nakakonekta; ang ikaapat na hakbang ay upang tumugma sa mga parameter ng mga bahagi sa pamamagitan ng espesyal na kagamitan upang matiyak ang maayos na paghahatid ng data sa BMS system; sa wakas ay simulan ang forklift at patuloy na subaybayan ang boltahe at temperatura ng baterya. At iba pang data ng katayuan, i-verify na ang function ng komunikasyon ay matatag bago ilagay sa operasyon.

Dapat tandaan na ang mga orihinal na bahagi ay dapat gamitin sa buong proseso ng pagpapalit upang maiwasan ang mga pangalawang pagkabigo na dulot ng hindi pantay na mga detalye ng mga bahagi; mahigpit na sundin ang mga detalye ng proteksyon sa pagkawala ng kuryente sa panahon ng operasyon upang maiwasan ang panganib ng electric shock; pagkatapos makumpleto ang pagpapalit, isang walang-load na pagsubok na operasyon ay kinakailangan nang hindi bababa sa 30 minuto., at pagkatapos ay isagawa ang aktwal na operasyon pagkatapos makumpirma na walang abnormalidad.
