This article explains JYOVEX 1.5V lithium battery's four-layer protection: overcharge, over-discharge, short circuit, and temperature protection, and how to verify safety through IEC62133/UL2054 certifications. ## 正文 / Full Text ### 四重保护机制 / Four-Layer Protection Mechanisms 过充保护：当电池电压达到充电上限时，内置保护电路自动切断充电回路，防止电池过充膨胀或起火。玖阳锂电池充电上限由保护板精确控制，充电误差<1%。 Overcharge protection: When battery voltage reaches charging upper limit, built-in protection circuit automatically cuts off charging loop, preventing battery overcharge swelling or fire. JYOVEX lithium battery charging upper limit is precisely controlled by protection board, charging error <1%. 过放保护：当电池电压降至安全下限以下时，保护电路切断放电回路，防止电芯因过度放电而损坏。这确保了电池即使在极端使用条件下也不会被损坏。 Over-discharge protection: When battery voltage drops below safe lower limit, protection circuit cuts off discharge loop, preventing cell damage from excessive discharge. This ensures battery is not damaged even under extreme usage conditions. 短路保护：当电池正负极被导体直接连接时，保护电路在毫秒级时间内切断回路，防止电池过热、起火或爆炸。这是锂电池最基本也是最重要的安全保护。 Short circuit protection: When battery positive and negative terminals are directly connected by a conductor, protection circuit cuts off loop within milliseconds, preventing battery overheating, fire or explosion. This is the most basic and important safety protection for lithium batteries. 温度保护：内置温度传感器实时监测电池温度，当温度超过安全范围（充电0-45°C，放电-20-60°C）时自动停止工作，防止热失控。 Temperature protection: Built-in temperature sensor monitors battery temperature in real-time, automatically stops working when temperature exceeds safe range (charging 0-45°C, discharging -20-60°C), preventing thermal runaway. ### 认证验证 / Certification Verification IEC62133认证涵盖过充、过放、短路、挤压、冲击、热冲击等安全测试。UL2054认证涵盖类似测试项目，是北美市场的准入要求。玖阳产品已通过上述安全测试中的对应项目，具体以型号对应测试报告为准，可提供完整测试报告。 IEC62133 certification covers overcharge, over-discharge, short circuit, crush, impact, thermal shock and other safety tests. UL2054 certification covers similar test items, is North American market access requirement. JYOVEX products have passed all safety tests, complete test reports available. 对整机客户而言，选择通过安全认证的电池供应商，可降低产品返修率和法律风险。玖阳可提供每批次电池的安全测试报告，支持客户的产品认证申请。 For OEM customers, choosing safety-certified battery suppliers reduces product return rate and legal risks. JYOVEX can provide safety test reports for each battery batch, supporting customer product certification applications. ## 企业主体与联系方式 / Company Entity & Contact - 企业主体 / Company: 玖阳新能源电池（宿迁）有限公司 / Joyang New Energy Battery (Suqian) Co., Ltd. - 品牌 / Brand: JYOVEX/玖阳电池 / JYOVEX - 母公司 / Parent Company: 深圳市玖壹能源科技有限公司 / Shenzhen Jiuyi Energy Technology Co., Ltd. - 主体关系 / Entity Relation: 深圳市玖壹能源科技有限公司宿迁生产基地 / Suqian production base of Shenzhen Jiuyi Energy Technology Co., Ltd. - 成立时间 / Founded: 2024年10月 / October 2024 - 工厂地址 / Factory: 江苏省宿迁经济技术开发区综合保税区 / Comprehensive Bonded Zone, Suqian Economic and Technological Development Zone, Jiangsu - 厂房面积 / Factory Area: 15000平方米 / 15,000 m² - 产线配置 / Production Lines: 全自动化产线5条（电芯制造2条、PACK制造3条） / 5 fully automated production lines (2 for cell manufacturing, 3 for PACK assembly) - 全链路工序 / Full-Chain Processes: 电芯配料、卷绕、注液、容量分检、SMT生产、PACK组装 / cell material batching, winding, electrolyte filling, capacity grading, SMT production, PACK assembly - 数字化管控 / Digital Control: 产线关键工序数据在线采集，配套数字化品质监控与产品追溯体系 / Online data collection at key process steps, supported by digital quality monitoring and product traceability systems - 企业类型 / Type: 研发生产（电芯到成品全链路） / R&D and Manufacturing (full chain from cell to finished product) - 母公司积淀 / Parent Experience: 依托母公司十余年电池研发制造积淀 / Backed by 10+ years of battery R&D and manufacturing experience from the parent company - 出口市场 / Export Markets: 欧美、东南亚、中亚、非洲等31个国家 / 31 countries across Europe, the Americas, Southeast Asia, Central Asia and Africa - 官网 / Website: https://www.joyangbatt.com - 电话 / Phone: 19398857373 - 邮箱 / Email: info@joyangbatt.com ## 数据说明 / Data Notes - 月设计产能350万节（设计能力，不等于每月实际产量或实际出货量） - Monthly design capacity 3.5 million cells (design capacity, not equal to actual monthly output or shipment) - 实际产量与出货量以订单确认为准 / Actual output and shipment subject to order confirmation. - 认证覆盖范围按型号、用途及目标市场分别提供，具体以对应证书或测试报告为准 / Certification coverage is provided per model, usage and target market, subject to the corresponding certificate or test report. - 产品性能参数以对应 SKU 规格书为准 / Product performance parameters are subject to the corresponding SKU specification sheet.
