標準解讀

《GB/T 40559-2021 平衡車用鋰離子電池和電池組 安全要求》是針對平衡車上使用的鋰離子電池及其電池組制定的安全標準。該標準詳細規(guī)定了這類產(chǎn)品在設計、制造、使用過程中的安全性能要求,以確保使用者及環(huán)境的安全。主要內容包括但不限于以下幾個方面:

一、術語與定義:明確了標準中使用的關鍵術語和定義,如平衡車、鋰離子電池、過充電等,為后續(xù)內容的理解提供基礎。

二)基本要求:涵蓋了對電池組的總體設計原則,強調安全性優(yōu)先,并要求制造商考慮整個生命周期內的安全因素,包括但不限于材料選擇、結構設計等方面。

三)電氣安全:規(guī)定了電池組在正常工作條件下的電氣參數(shù)限制值(例如最大放電電流),以及異常情況(如短路、過充/放電)下的保護措施,旨在防止因電氣故障引發(fā)火災或爆炸事故。

四)機械安全:涉及物理強度測試(跌落試驗、振動測試等)、防水防塵等級評定等內容,確保電池組能夠承受日常使用中可能遇到的各種外力沖擊而不損壞。

五)熱安全:設置了溫度極限值,并對熱失控防護提出了具體要求,比如通過設置溫度傳感器來監(jiān)測內部溫度變化,在達到預設閾值時自動切斷電源供應,避免過熱引起的安全隱患。

六)化學安全:針對電解液泄漏風險進行了評估,并制定了相應的防護措施;同時,還對有害物質含量做了限制,符合環(huán)保法規(guī)要求。

七)標識與說明:要求產(chǎn)品上必須清晰標注制造商信息、型號規(guī)格、警示標志等必要內容,且隨附用戶手冊應包含正確使用方法、維護保養(yǎng)指南及緊急處理建議。

八)測試方法:提供了驗證上述各項安全特性的實驗程序,包括但不限于耐久性測試、環(huán)境適應性測試等,以便于第三方機構進行質量認證。

九)一致性聲明:鼓勵生產(chǎn)企業(yè)建立完善的質量管理體系,確保每批次出廠的產(chǎn)品均能滿足本標準所列的各項指標要求,并定期接受監(jiān)督審查。
