案例背景
本案例取自新能源车载动力电池维修手册素材,内容包含基础保养规范、日常维保项目、电池管理系统功能与故障处置三大模块,涉及电压温度限值、均衡触发条件、十余项检修条目、系统工作原理及高压安全警示等多层级技术信息。文本目标受众为售后维修人员、车辆驾驶员及运维人员,是电池系统维保环节的通用技术指引。翻译需对标海外车企原厂维修手册的规范语体、统一专业术语、区分技术说明与安全警示的语气层级,该处理思路可作为新能源汽车技术文档翻译的典型教学案例。
Ø 原文与译文
锂电池的保养与维护 不要过充和过放。磷酸铁锂电池在充电时不要超过3.65V(最高不超过3.9V),在放电时不要低于2.5V。 不要在低于0度时充电,充电温度最好在5度以上。如果低温情况下,需要先将电池预加热后再充电。 当动力电池在长期放置条件下,不可使用,要先对电池进行小电流充放电后再使用,充放电电流一般小于0.33C。 动力锂电池在容量降低到起始容量的80%以下,就不能作动力锂电池使用。 |
Maintenance Instructions for Lithium Batteries Overcharging and overdischarging of the battery are strictly prohibited. For lithium iron phosphate (LFP) batteries, the charging voltage shall be limited to a maximum of 3.65 V, with an absolute voltage ceiling of 3.9 V, and the discharge cut-off voltage must not drop below 2.5 V. Charging is prohibited when ambient temperature is below 0 °C. The recommended charging temperature range starts above 5 °C. If charging under low-temperature conditions is unavoidable, preheat the battery pack fully before charging. If a traction lithium battery is to be reused after long-term storage, complete low-current charge and discharge cycles before operation. The charge and discharge current shall be controlled below 0.33 C as a general requirement. A traction lithium battery shall be retired from power applications once its available capacity declines to less than 80% of the original rated capacity.

锂电池在充电到单体最高电压,或放电到最低电压,如果最大压差在200-300mV时,需要对电池进行均衡处理。 对电池的日常维护,包括电池的均衡、电池的一次绝缘检测、二次绝缘检测、电极螺栓松紧的检查、电池是否有短路、电压采样线束和温度采样线束的检查、电池模组在电池箱内固定情况、热管理系统(加热、冷却)是否正常工作、高低压接插件是否正常工作、电池箱固定装置是否有损坏。 |
Battery equalization is required when the lithium battery reaches the maximum cell charging voltage or the minimum discharging voltage, and the maximum cell voltage difference ranges from 200 mV to 300 mV. Routine maintenance of lithium batteries covers the following items: battery equalization, primary and secondary insulation detection, inspection of electrode bolt tightness, battery short-circuit inspection, integrity inspection of voltage and temperature sampling harnesses, fixation condition of internal battery modules, functional inspection of the thermal management system (heating and cooling functions), functional inspection of high and low-voltage connectors, and damage inspection of battery compartment fixing components. |
车载动力锂电池的每个单体都必须实现动态的监控和管理,必须将管理的信息与整车的驱动系统进行反馈传递,以指导驱动控制器的驱动运行方式。在每箱电池上都安装有电池检测模块,用于检测每节电池单体的电压和箱体的温度。每个从控模块与主控模块之间通过CAN通讯。电池信息通过CAN通讯在仪表上显示。当电池检测系统出现故障时,请驾驶员针对故障信息找故障原因,如涉及电池电容等高压部件,请勿触摸。联系相关人员进行维修。 |
Each cell of the on-board traction lithium battery pack shall be subject to dynamic monitoring and management. The battery management data shall be fed back to the vehicle drive system to guide the operation strategy of the drive controller. A battery monitoring unit (BMU) is installed in each battery pack to measure the voltage of individual cells and the pack internal temperature. All slave control modules communicate with the master control module via CAN bus. Battery status data is displayed on the instrument cluster through CAN communication. In the event that a fault occurs in the battery monitoring system, the driver shall identify the root cause based on the fault information. DO NOT touch any high-voltage (HV) components if the fault involves HV parts such as battery capacitors. Contact qualified service personnel for repair. |
Ø 译文解析:
此翻译针对不同功能模块采用差异化语体策略。保养禁令与参数限制部分使用规范强制语气,维保条目采用统一的名词化结构罗列,系统说明部分保持客观技术表述,安全警示则强化格式辨识度。全文术语保持一致,参数表述符合国际电池行业通用书写规范,在完整传递技术信息的同时,遵循英文维修手册的行文逻辑与排版习惯。
1) 本段文本翻译难点主要在于中英技术句式的转换与专业语境的统一。中文原文多为流水式短句、祈使句,符合国内技术说明的表达习惯,却不符合英文维保手册严谨、规整的句法规范,需在保留核心技术参数不变的前提下,重构句式结构、补充语法成分。同时,文本包含多项电池阈值参数、工况限定条件,需准确区分推荐值与极限值、常规工况与特殊工况的语义差异,规避语义混淆。此外,需统一动力电池领域专业语体,平衡技术文本的强制性与规范性,避免口语化表述,对标海外车辆维修手册的行文逻辑与专业标准。

Lithium Battery Maintenance Instructions
Avoid overcharging and overdischarging. For lithium iron phosphate batteries, the charging voltage shall not exceed 3.65 V (absolute maximum 3.9 V), and the discharge cut-off voltage shall not drop below 2.5 V.
Do not charge the battery at temperatures below 0 ℃; the optimal charging temperature is above 5 ℃. If charging under low-temperature conditions, preheat the battery prior to charging.
If a traction battery has been stored for an extended period and remains idle, perform low-current charge-discharge cycles before putting it into service. The charge and discharge current shall generally be less than 0.33 C.
Once the capacity of a traction lithium battery falls below 80% of its rated initial capacity, it shall no longer be deployed as a power traction battery.
AI译后编辑要点:
(1) 改写核心禁令句式,符合维保手册语体。将普通直译句式优化为Overcharging and overdischarging of the battery are strictly prohibited,替换通俗的规避式表达,符合海外技术规范的官方行文风格,适配安全警示条款的语体要求;
(2) 拆分电压参数层级,准确区分技术阈值。原文仅罗列电压数值,译文通过maximum of 3.65 V与absolute voltage ceiling of 3.9 V分层表述,明确常规充电限值与绝对安全极限值,精准还原动力电池两级电压管控标准,符合新能源电池维保参数标注的行业规范,避免技术误导;
(3) 针对原文“长期放置后使用”的模糊表述,译文细化为be reused after long-term storage,同时明确低温充电unavoidable的适用前提,补全原文隐含的工况限定条件,界定特殊操作场景,让技术操作规范更严谨,适配实操类维保文档的精准性要求;
(4) 统一采用traction lithium battery、original rated capacity等行业通用术语,将口语化表达“不能使用”规范译为be retired from power applications,对标国际新能源车辆维保专业术语体系,准确表达电池退役的行业专业概念,规避中式英语表述,符合海外技术文档阅读标准。
2) 本段翻译难点集中体现在工况逻辑重组与工程语体标准化两方面。中文原文多并列短句,条件状语语序松散,直译易造成英文语句逻辑割裂;文本包含电芯压差阈值、多类维保检测项目,大量行业专属术语需统一规范,并同时区分普通检查与完整性检测的语义差异。其次,原文罗列十余项维护条目,存在多处简略表述,无法区分操作层级。翻译过程中既要保留全部技术参数与检修条目,又要重构句式逻辑,采用车企维修手册通用的书面表达,精简重复冗余词汇,统一部件标准化称谓,使文本符合海外新能源设备技术文档的行文范式。

When lithium batteries are charged to the maximum cell voltage or discharged to the minimum cell voltage, balancing treatment shall be performed on the batteries if the maximum voltage difference ranges from 200 mV to 300 mV.
Daily maintenance of batteries includes battery balancing, primary insulation testing and secondary insulation testing of batteries, inspection of the tightness of electrode bolts, check for internal short circuits in batteries, examination of voltage sampling wiring harnesses and temperature sampling wiring harnesses, verification of the fixing condition of battery modules inside the battery box, functional inspection of the thermal management system (heating and cooling functions), operational check of high-voltage and low-voltage connectors, and inspection for damage to battery box fixing devices.
AI译后编辑要点:
(1) 重构主句与限定条件的排布顺序,以Battery equalization is required作为主句前置,操作指令直观清晰,符合英文规范条款先规定、后说明前提的写作习惯;
(2) 增加covers the following items作为总起引导语,清晰划分总述与分项内容,优化行文架构,符合外文维保手册分条说明的逻辑;
(3) 将笼统描述线束检查的examination替换为integrity inspection,准确体现对线束完好性、有无破损虚接的检修核心要求,专业指向更明确,适配维保实操场景。
3) 本段翻译难点集中体现在语体分层把握与隐含逻辑梳理两方面。前半段系统原理表述需保持技术文档的客观严谨,后半段故障操作指引则需传递安全警示的强制约束力,两类语气需自然切换。中文原文多为无主语短句,功能递进关系隐含其中,直译易造成英文结构松散;同时涉及电控系统专属缩略语与部件称谓,需匹配整车厂维修手册的通用缩写规范。此外,“相关人员”此类模糊指代需结合维修场景明确限定,避免安全指引产生歧义。
经AI辅助翻译并优化提示词后,生成以下译文:
Every single cell of the vehicle-mounted traction lithium battery shall be dynamically monitored and managed. The managed battery data shall be fed back and transmitted to the vehicle drive system to regulate the operating logic of the drive controller. Each battery compartment is equipped with a battery monitoring module to measure the voltage of every single cell and the internal temperature of the compartment. Communication between each slave control module and the master control module is realized via CAN bus. Battery operating data is displayed on the instrument panel through CAN communication. If a fault occurs in the battery monitoring system, the driver shall troubleshoot according to the fault codes. Do not touch high-voltage components including battery capacitors when such components are involved in faults. Qualified personnel must be contacted for maintenance work.
AI译后编辑要点:
(1) 优化安全警示的呈现形式。将高压部件触碰禁令译为大写的DO NOT,替代普通否定句式,契合原厂维修手册中高压安全警示的标准化方式;强化警示辨识度,符合维保文档安全信息的呈现惯例;
(2) 规范行业缩略语的使用逻辑。首次出现电池检测模块时标注battery monitoring unit (BMU),CAN通讯补充为CAN bus明确总线属性,既保证初次阅读者理解全称含义,又符合技术文档“首次标注、后续复用”的缩略语使用规范;
(3) 梳理原文短句的逻辑层级。将原文连续并列的监控、反馈、调控三个功能环节,重构为递进式的英文主从结构,明确数据流向与功能因果关系,避免直译造成句式碎片化,符合英文技术说明的表达逻辑;
(4) 细化模糊指代的语义边界。将“相关人员”明确译为qualified service personnel,限定为具备专业资质的维修人员,而非泛指关联人员,消除安全指引中的责任模糊地带,契合高压操作安全规范的严谨性要求。
