        Intrinsic-Safe Module

        概述 Overview


        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.
