Mayankho Oyendetsera Kutentha kwa Machitidwe a Batri

Palibe kukayika kuti kutentha kumakhudza kwambiri magwiridwe antchito, moyo, ndi chitetezo cha mabatire amagetsi. Kawirikawiri, tikuyembekeza kuti makina a batire azigwira ntchito pamlingo wa 15 ~ 35℃, kuti akwaniritse mphamvu yabwino kwambiri yotulutsa ndi kulowetsa, mphamvu yayikulu yomwe ilipo, komanso moyo wautali kwambiri (ngakhale kuti kusungirako kutentha kochepa kumatha kukulitsa moyo wa batire pakalendala, koma sizomveka kuchita kusungirako kutentha kochepa mu ntchito, ndipo mabatire ndi ofanana kwambiri ndi anthu pankhaniyi).

Pakadali pano, kasamalidwe ka kutentha kwa makina a batri yamagetsi kangagawidwe m'magulu anayi, kuzizira kwachilengedwe, kuzizira kwa mpweya, kuzizira kwamadzimadzi, ndi kuzizira mwachindunji. Pakati pawo, kuzizira kwachilengedwe ndi njira yowongolera kutentha yopanda mphamvu, pomwe kuzizira kwa mpweya, kuzizira kwamadzimadzi, ndi mphamvu yolunjika zimagwira ntchito. Kusiyana kwakukulu pakati pa zitatuzi ndi kusiyana kwa njira yosinthira kutentha.

· Kuziziritsa kwachilengedwe
Kuziziritsa kwaulere kulibe zida zina zowonjezera zosinthira kutentha. Mwachitsanzo, BYD yagwiritsa ntchito kuziziritsa kwachilengedwe mu Qin, Tang, Song, E6, Tengshi ndi mitundu ina yomwe imagwiritsa ntchito maselo a LFP. Zikumveka kuti BYD yotsatira idzasintha kukhala kuziziritsa kwamadzimadzi kwa mitundu yomwe imagwiritsa ntchito mabatire a ternary.

· Kuziziritsa Mpweya (Chotenthetsera Mpweya cha PTC)
Kuziziritsa mpweya kumagwiritsa ntchito mpweya ngati njira yosamutsira kutentha. Pali mitundu iwiri yodziwika bwino. Yoyamba imatchedwa kuti passive air cooling, yomwe imagwiritsa ntchito mwachindunji mpweya wakunja posinthana kutentha. Mtundu wachiwiri ndi active air cooling, yomwe imatha kutentha kapena kuziziritsa mpweya wakunja isanalowe mu batire. Kale, mitundu yambiri yamagetsi yaku Japan ndi Korea idagwiritsa ntchito njira zoziziritsira mpweya.

· Kuziziritsa madzi
Kuziziritsa kwamadzimadzi kumagwiritsa ntchito mankhwala oletsa kuzizira (monga ethylene glycol) ngati njira yosamutsira kutentha. Nthawi zambiri pamakhala ma circuit osiyanasiyana osinthira kutentha mu yankho. Mwachitsanzo, VOLT ili ndi circuit ya radiator, circuit ya air conditioner (Mpweya Woziziritsa wa PTC), ndi dera la PTC (Chotenthetsera Choziziritsira cha PTC). Dongosolo loyendetsera mabatire limayankha ndikusintha ndikusintha malinga ndi njira yoyendetsera kutentha. TESLA Model S ili ndi dera lozungulira lomwe limazizira mota. Batire ikafunika kutenthedwa kutentha kochepa, dera lozizira mota limalumikizidwa limodzi ndi dera lozizira batire, ndipo mota imatha kutenthetsa batire. Batire yamagetsi ikatentha kwambiri, dera lozizira mota ndi dera lozizira batire zidzasinthidwa nthawi imodzi, ndipo makina awiri oziziritsira adzachotsa kutentha pawokha.

1. Chokonzetsera mpweya

2. Kondensa yachiwiri

3. Fani yachiwiri ya condenser

4. Fani yotenthetsera mpweya

5. Chowunikira mpweya woziziritsa (mbali ya mpweya wozizira kwambiri)

6. Chowunikira kutentha kwa mpweya woziziritsa mpweya (mbali yothamanga kwambiri)

7. Chokometsera mpweya wamagetsi

8. Choyezera mpweya woziziritsa (mbali yotsika ya mpweya)

9. Chowunikira kutentha kwa mpweya woziziritsa mpweya (mbali yotsika ya mpweya)

10. Valavu yokulitsa (yoziziritsira)

11. Valavu yokulitsa (chotenthetsera)

· Kuziziritsa mwachindunji
Kuziziritsa mwachindunji kumagwiritsa ntchito refrigerant (zinthu zosintha magawo) ngati njira yosinthira kutentha. Refrigerant imatha kuyamwa kutentha kwakukulu panthawi yosinthira gawo la gasi ndi madzi. Poyerekeza ndi refrigerant, mphamvu yosamutsa kutentha imatha kuwonjezeka ndi katatu, ndipo batri imatha kusinthidwa mwachangu. Kutentha mkati mwa dongosolo kumatengedwa. Njira yoziziritsira mwachindunji yagwiritsidwa ntchito mu BMW i3.

 

Kuwonjezera pa mphamvu yozizira, njira yoyendetsera kutentha kwa batri iyenera kuganizira kusinthasintha kwa kutentha kwa mabatire onse. PACK ili ndi ma cell mazana ambiri, ndipo sensa yowunikira kutentha singathe kuzindikira selo lililonse. Mwachitsanzo, pali mabatire 444 mu gawo la Tesla Model S, koma malo awiri okha ozindikira kutentha ndi omwe amakonzedwa. Chifukwa chake, ndikofunikira kupanga batri kukhala yogwirizana momwe mungathere kudzera mu kapangidwe ka kayendetsedwe ka kutentha. Ndipo kusinthasintha kwa kutentha kwabwino ndikofunikira kuti pakhale magwiridwe antchito okhazikika monga mphamvu ya batri, moyo, ndi SOC.
