標(biāo)準(zhǔn)解讀

GB 44240-2024是一項(xiàng)針對電能存儲系統(tǒng)中使用的鋰蓄電池和電池組的安全要求標(biāo)準(zhǔn)。此標(biāo)準(zhǔn)旨在確保此類產(chǎn)品的設(shè)計(jì)、生產(chǎn)、使用及維護(hù)過程中符合國家安全規(guī)定，預(yù)防潛在的電氣火災(zāi)、爆炸、漏電等危險(xiǎn)情況，保護(hù)用戶生命財(cái)產(chǎn)安全和環(huán)境。以下是該標(biāo)準(zhǔn)涵蓋的主要內(nèi)容要點(diǎn)：

  1. 適用范圍：明確了標(biāo)準(zhǔn)適用于固定式和移動式電能存儲系統(tǒng)中使用的鋰離子電池和電池組，包括但不限于太陽能、風(fēng)能儲存系統(tǒng)以及電動汽車、通信基站備用電源等應(yīng)用領(lǐng)域。

  2. 安全設(shè)計(jì)原則：要求鋰蓄電池和電池組在設(shè)計(jì)階段需遵循安全優(yōu)先原則，包括過充電保護(hù)、過放電保護(hù)、短路保護(hù)、溫度控制及熱失控管理機(jī)制，確保電池在異常狀態(tài)下的安全性能。

  3. 電池結(jié)構(gòu)與材料：規(guī)范了電池的結(jié)構(gòu)設(shè)計(jì)、外殼材質(zhì)及內(nèi)部組件的選用標(biāo)準(zhǔn)，強(qiáng)調(diào)使用阻燃、耐高溫材料，提高電池的整體安全等級。

  4. 電氣安全要求：詳細(xì)說明了電氣連接、絕緣電阻、耐電壓測試等電氣安全性能指標(biāo)，確保電池在正常及異常工作條件下的電氣安全。

  5. 熱管理與散熱要求：規(guī)定了電池組的熱管理系統(tǒng)設(shè)計(jì)標(biāo)準(zhǔn)，包括有效散熱途徑、溫控傳感器的布置、熱失控預(yù)警及防護(hù)措施，以防止熱積累導(dǎo)致的安全事故。

  6. 機(jī)械安全與環(huán)境適應(yīng)性：要求電池組具有足夠的機(jī)械強(qiáng)度，能夠承受預(yù)期的運(yùn)輸、安裝及使用過程中的外力沖擊，同時(shí)要能在特定的環(huán)境條件下（如高低溫、濕度變化）保持正常功能。

  7. 電池管理系統(tǒng)(BMS)要求：強(qiáng)調(diào)了電池管理系統(tǒng)的重要性，要求其具備精確的電量計(jì)量、狀態(tài)監(jiān)測、故障診斷及保護(hù)控制功能，以實(shí)現(xiàn)電池的智能化管理與保護(hù)。

  8. 測試與認(rèn)證：規(guī)定了電池和電池組在出廠前必須通過的一系列安全測試項(xiàng)目，包括但不限于循環(huán)壽命測試、濫用測試（如外部短路、過充過放、碰撞試驗(yàn)）及環(huán)境適應(yīng)性測試，并要求取得相應(yīng)的安全認(rèn)證。

  9. 標(biāo)識與說明書：要求產(chǎn)品上明確標(biāo)注安全警告、操作指南及維護(hù)信息，提供詳細(xì)的用戶手冊，確保用戶正確使用和維護(hù)電池系統(tǒng)。

  10. 回收與處置：雖然可能不直接包含在安全要求內(nèi)，但標(biāo)準(zhǔn)可能提及電池的環(huán)?；厥蘸吞幹弥笇?dǎo)原則，以減少對環(huán)境的影響。

GB44240—2024

前言

本文件按照GB/T1.1—2020《標(biāo)準(zhǔn)化工作導(dǎo)則第1部分：標(biāo)準(zhǔn)化文件的結(jié)構(gòu)和起草規(guī)則》的規(guī)

定起草。

請注意本文件的某些內(nèi)容可能涉及專利。本文件的發(fā)布機(jī)構(gòu)不承擔(dān)識別專利的責(zé)任。

本文件由中華人民共和國工業(yè)和信息化部提出并歸口。

Ⅲ

GB44240—2024

引言

本文件僅考慮鋰蓄電池和電池組最基本的安全要求以提供對人身和財(cái)產(chǎn)安全的保護(hù)，而不涉及性能

和功能特性。

隨著技術(shù)和工藝的進(jìn)一步發(fā)展，必然會要求進(jìn)一步修訂本文件。

在本文件范圍內(nèi)鋰蓄電池和電池組導(dǎo)致的危險(xiǎn)是指：

—漏液，可能會直接對人體構(gòu)成化學(xué)腐蝕危害，或?qū)е码姵毓╇姷碾娮釉O(shè)備內(nèi)部絕緣失效間接造

成電擊、著火等危險(xiǎn)；

—起火，直接燒傷人體，或?qū)﹄姵毓╇姷碾娮釉O(shè)備造成著火危險(xiǎn)；

—爆炸，直接危害人體，或損毀設(shè)備；

—過熱，直接對人體引起灼傷，或?qū)е陆^緣等級下降和安全元器件性能降低，或引燃可燃液體；

—電擊，由于電流流過人體而引起的傷害，例如燒傷、肌肉痙攣、心室纖維性顫動等。

對于輸出電壓超過安全電壓限值（直流60V）的電池組，可能直接會引發(fā)電擊危險(xiǎn)。而對于通過逆

變后能產(chǎn)生超過安全電壓限值（直流60V或者交流峰值42.4V）的電池組，也同樣可能會引發(fā)電擊

危險(xiǎn)。

在確定鋰蓄電池或電池組采用何種設(shè)計(jì)方案時(shí)的優(yōu)先次序：

—首先，如有可能，優(yōu)先選擇安全性高的材料；

—其次，如果無法實(shí)行以上原則，則需設(shè)計(jì)保護(hù)裝置，減少或消除危險(xiǎn)發(fā)生的可能性，如增加保

護(hù)裝置等；

—最后，不能徹底避免的殘留危險(xiǎn)采用標(biāo)識和說明。

上述原則不能代替本文件的詳細(xì)要求，僅為讓設(shè)計(jì)者了解這些要求所依據(jù)的原則。

鋰蓄電池和電池組的安全性與其材料選擇、設(shè)計(jì)、生產(chǎn)工藝、運(yùn)輸及使用條件有關(guān)。其中使用條件

包含了正常使用條件、可合理預(yù)見的誤使用、濫用及故障條件，還包括影響其安全的環(huán)境條件諸如溫

度、海拔等因素。

鋰蓄電池和電池組的安全要求覆蓋上述所有因素對人員引起的危險(xiǎn)。人員是指維修人員和使用

人員。

維修人員是指電子設(shè)備及其電池的維修人員，維修人員在有明顯危險(xiǎn)時(shí)能運(yùn)用專業(yè)技能避免可能的

傷害。但是，需對維修人員就意外危險(xiǎn)進(jìn)行防護(hù)，例如用標(biāo)識或警示說明以提醒維修人員有殘留的

危險(xiǎn)。

使用人員是指除維修人員以外的所有人員。安全保護(hù)要求是假定使用人員未經(jīng)過如何識別危險(xiǎn)的培

訓(xùn)，但不會故意制造危險(xiǎn)狀況而提出的。
