Problema sa pagpapahina ng baterya na may mababang temperatura: Pagbabahagi ng teknikal na solusyon ng BYD electric cold storage forklift(larawan1)

Sa low-temperature storage operation scenario, isa sa mga pangunahing sakit na kinakaharap ng mga electric forklift ay ang problema sa pagpapahina ng baterya sa mababang temperatura na kapaligiran, na hindi lamang lubos na magpapaikli sa buhay ng baterya ng isang operasyon, ngunit mababawasan din ang kabuuang buhay ng serbisyo ng baterya at dagdagan ang kabuuang halaga ng mga operasyon ng imbakan. Sa pamamagitan lamang ng paglilinaw sa mga sanhi ng pagpapahina ng mga baterya na may mababang temperatura at pagtutugma ng mga naka-target na solusyon sa teknikal na adaptasyon ay epektibong malulutas ang sakit na punto ng industriyang ito.

Ang pangunahing sanhi ng pagpapahina ng baterya sa mababang temperatura na kapaligiran

Ang mababang temperatura na kapaligiran ay hahantong sa isang makabuluhang pagbaba sa aktibidad ng electrolyte sa loob ng baterya, isang malaking pagtaas sa paglaban ng paglipat ng ion, at isang direktang pagbawas sa kahusayan ng conversion ng pag-charge at pagdiskarga. Ang kapasidad ng paglabas ay maaari lamang umabot sa 60% hanggang 70% ng normal na temperatura. Bilang karagdagan, ang pagkakaiba sa temperatura na dulot ng madalas na pagpasok at paglabas ng mga forklift sa malamig na imbakan ay madaling bumuo ng condensation sa ibabaw ng kompartamento ng baterya at mga bahagi ng elektronikong kontrol. Ang pangmatagalang akumulasyon ay makakasira sa mga bahagi at higit na magpapalala sa pagpapahina ng pagganap ng baterya. Sa matinding mga kaso, maaari rin itong magdulot ng mga panganib sa kaligtasan.

Ang pangunahing solusyon sa adaptasyon ng teknolohiya ng electric cold storage forklift

Pag-optimize ng cell ng baterya at sistema ng pagkontrol sa temperatura

Ang mga baterya na may malawak na hanay ng temperatura ay iniangkop para sa mga sitwasyong mababa ang temperatura. Kasabay nito, ang isang high-density insulation layer ay naka-install sa paligid ng battery pack, at isang intelligent na preheating system ay naka-install. Kapag ang ambient temperature ay mas mababa kaysa sa itinakdang threshold, awtomatikong sisimulan ng system ang preheating function. Ang temperatura ay stable sa loob ng isang makatwirang hanay, na binabawasan ang epekto ng mababang temperatura sa aktibidad ng cell mula sa ugat, at binabawasan ang hindi kinakailangang pagkawala ng pagganap.

Pagse-sealing ng sasakyan at anti-condensation na disenyo

Pagbutihin ang antas ng sealing at proteksyon ng kompartamento ng baterya at mga bahagi ng elektronikong kontrol ng sasakyan, at mag-spray ng espesyal na anti-condensation coating sa ibabaw ng mga pangunahing bahagi upang maiwasan ang pagpasok ng singaw ng tubig sa panloob na istraktura na dulot ng pagkakaiba ng temperatura, bawasan ang panganib ng pagguho ng condensation sa mga elektronikong bahagi, at protektahan ang buong sasakyan. Ang matatag na operasyon ng sistema ng circuit sa mga sitwasyon ng pagbabagu-bago ng temperatura.

Pagsasaayos ng diskarte sa pag-charge at pagdiskarga sa mga sitwasyong mababa ang temperatura

I-optimize ang lohika ng pag-charge at pagdiskarga ng buong sasakyan para sa mababang temperatura na kapaligiran, at naaangkop na babaan ang kasalukuyang threshold ng discharge sa mababang temperatura upang maiwasan ang karagdagang pagkawala ng cell na dulot ng mataas na kasalukuyang discharge. Sa yugto ng pag-charge, idinaragdag ang proseso ng pre-temperature ng baterya. Pagkatapos tumaas ang temperatura ng baterya sa isang makatwirang hanay, magsisimula ang regular na pag-charge upang maiwasan ang mga problema tulad ng virtual na kuryente at pagkasira ng cell na dulot ng mababang temperatura na pag-charge.

Pang-araw-araw na mga punto ng pagpapanatili ng mga baterya ng forklift sa mga sitwasyong mababa ang temperatura

Sa pang-araw-araw na operasyon, subukang iwasan ang mga forklift na idle sa matinding sub-zero na kapaligiran sa loob ng mahabang panahon, at iparada ang mga sasakyan sa mga transitional na lugar na may katamtamang temperatura sa mga oras na hindi gumagana. Regular na suriin ang integridad ng layer ng pagkakabukod ng baterya at istraktura ng sealing, at ayusin ang pinsala sa oras. Kasabay nito, gumana nang mahigpit alinsunod sa karaniwang proseso ng pag-charge na may mababang temperatura. Huwag direktang singilin ang sasakyan sa napakababang temperatura na kapaligiran.

Ang mga teknikal na solusyon na ito ay aktwal na na-verify ng isang malaking bilang ng mga low-temperature storage scenario, na maaaring epektibong bawasan ang attenuation rate ng mga baterya sa mga low-temperature na kapaligiran, pahabain ang kabuuang buhay ng serbisyo ng mga electric forklift, at tulungan ang mga low-temperature storage operator na bawasan ang komprehensibong operasyon at mga gastos sa pagpapanatili at pagbutihin ang kahusayan sa pagpapatakbo.
