鋰電池在運作與充放電過程中會產生熱能,若熱能無法有效導出,可能導致熱失控,因此有下列三種常用改善方法:
鋰電池隨使用時間會產生輕微膨脹,若模組無預留彈性空間,容易擠壓主板或外殼,造成結構損壞或安全風險,因此通常建議設計預留 10~15% 的膨脹緩衝區。
避免使用者因摔落或擠壓造成內部電路損傷造成短路,因此使用高強度外殼(如 ABS+PC、防火材料)或加裝橡膠墊、緩衝膠條;甚至在特殊使用場景,例如大型工程或軍警應用會搭配強固型專用電腦。
根據 EU 電池法等規範,結構設計應支援螺絲固定而非永久黏接,其中個別模組可獨立拆裝、並且不破壞產品主體,可重工使用;最後在電池條碼與規格標示,應可清晰辨識,才有辦法做到商品售後維修服務。
我們在產品結構開發流程中,會於設計初期就導入:
透過與 OEM 客戶的密切合作,我們協助多項相關產品進行驗證,符合國際安規與綠色設計標準。
