These electric dump trucks not only contribute to reducing carbon emissions but also provide operational advantages […]
Introduction to Electric Drive Motors in New Energy Vehicles With the rapid advancement of new energy vehicles (Nevs), Ko nga motuka hiko hiko kua riro i tetahi o nga waahanga matua o nga waka hiko (EFS). Ko te mahinga o enei motuka e pa ana ki te whai hua, tuarā maunga, me te wheako taraiwa o te ev. Kaore i rite ki te miihini whakauru o roto (Haupapa) […]
Kupu whakataki me te tere tere o te umanga hiko hiko, Ko te waahanga punaha hiko hiko kua nui te ahunga whakamua. Kei te haere tonu te hangarau hua, Ko te tauine o te whanaketanga ahumahi kei te whakawhānui ake, me nga rauemi hou me nga tukanga kei te puta ake. Kei te kitea te ahua o te whakauru. Na te mea nui o te taraiwa waka hiko […]
I nga tau tata nei, Ma te kaha o te tautoko mai i nga kaupapa here a-motu, Ko te umanga waka hiko parakore kua whanake tere. Kei te whakawhiti nga kaiwhakamahi o te wahie hinu tuku iho ki nga kaiwhakamahi Nev, me te mea he ahu whakamua hangarau hua, kaiwhakamahi’ Ko nga tikanga whakahaere me te maarama me whakapai ake hoki. I muri katoa, Ko nga waka hiko parakore he hua hou mo nga kaihoko maha. Ki te […]
1. Motuka hiko motuka hiko 1.1 Ko nga motuka hiko DC (EFS) He maha nga wa e whakamahia ana mo nga motuka whakahaere ngawari me o raatau utu iti. Ko nga momo tino noa e whakauru ana i nga motuka DC e tino koa ana me nga motuka kua werohia. Hoianō, Ko te aroaro o te rangatira me nga brosses e arahi ana ki te kakahu miihini, Te tono tiaki auau. Ko enei waahanga […]
1. Introduction Lithium-ion batteries are widely used in various industrial applications, and their safety has always been a key research topic. Studies have shown that mechanical abuse is one of the main causes of short circuits in lithium batteries during traffic accidents. Many studies have investigated the mechanical abuse of batteries. Wang Zhenpo et al. […]
Under the multiple influences of environmental protection and policies, the sales volume of new energy vehicles, especially electric vehicles, has been rising steadily and growing rapidly. Hoianō, behind the rapid development, the comments on electric vehicles have always been mixed. Hei tauira, they are energy-saving but the purchase cost is too high, they are environmentally […]
This article mainly focuses on the same battery system, under the same temperature conditions and water cooling strategy, using environmental chambers of different specifications and sizes, to study the influence of different positions of the air outlet and different test layouts on the electrical performance test results of the battery system. 1. Theoretical Analysis As […]
