百公里能耗17kWh 威馬首款電動轎車-30℃高寒測試曝光

   時間:2022-01-21 11:09 來源:快科技

近日,威馬汽車官方公布了旗下首款轎車M7的高寒測試情況,據了解,此次是在-30℃極寒環境下,針對空調、熱管理、動力性等項目進行嚴苛測試。

從官方公布的數據集來看,得益于分布式架構的電池熱管理系統,威馬M7在-30℃的極寒環境中,測試能耗僅為17kWh/100km

M7空調系統針對極熱、極寒天氣做了特別優化,在春秋兩季,5分鐘便可使車內溫度保持在頭部約22℃、腳部約33℃的舒適溫度區間;而在極熱和極寒環境中,17分鐘便可達到此舒適溫度。而數據表明,在常規環境下M7空調能耗占比僅3%,在極熱、極寒環境下,M7空調能耗占比也小于10%。

針對電池等核心部件,M7在-30℃環境中進行了持續12小時的多項“冰凍”試驗,“冰凍”后,M7整車冷啟動正常,熱管理系統均能正常且高效工作。同時,SOC從30%-80%充電時間僅30分鐘。

對于動力系統的測試標準只有一條,M7的電驅總成要跟常溫環境表現一致,性能不打折,功率、扭矩輸出正常,同時扭矩響應時間要小于80ms。

作為國內最早進軍新能源市場的車企,威馬可以說是“老資格”,但跟銷量均已突破十萬臺的“蔚小理”相比,威馬又妥妥的是“吊車尾”,首款轎車迄今也未交付。

最近,威馬首款電動車EX5遭遇了“四連燒”,又身陷“鎖電”糾紛之中,更有173名車主聯合發律師函向廠家維權,這都嚴重損害了威馬自身的品牌形象,也加大了消費者對其系列產品的疑慮。

只有重視問題、解決問題,才能贏得消費者信任,才能奪回市場,期待威馬官方能夠拿出行之有效的解決辦法。
