本征安全模块

Intrinsic-Safe Module

概述 Overview

振华新能源开发了基于三元18650电芯的本征安全模块,是系统解决方案的核心部件。电芯的电路自熔断、定向泄压、安全隔离设计可以确保失效的单颗电芯被有效隔离,保障模块的高安全性;模块采?#20204;?#37327;化材料和紧凑型结构,保证高能量密度;温度场分布和电流密?#30830;?#24067;的一致性设计使所有电芯处于相同的工作环境,故循环寿命与电芯相比无明显衰减;由于电芯具有很好的高低温性能,模块无需温控装置即可具有较宽的工作温度窗口。模块的具体规格依不同的应用领域而不同,且可进行定制开发。

Sinowatt has developed intrinsic-safe module based on 18650 cell, which is the critical part of our system solution. Thermal run-away cell can be isolated effectively by self-fusing connection, oriented pressure relief vent, safety spacing against thermal transmission, so the high safety of the module is guaranteed. The module has high energy density due to light-weighting material and compact structure. The uniformity design of thermal field and current density distribution guarantees that all cells work under same condition, so that there is no deterioration of module lifecompared with single cell. Module can be operated under wide temperature window without additional temperature-adjusting devices due to excellent cell performance. Dimension of modules varies according to different application fields, and can be tailored as well.
