储能电源产品安规简述|储能电源|元器件|安规|电路板

便携式储能产品近些年来发展迅猛，与储能电源质量相关的安全事故也频频发生，买家或电商平台越来越重视对储能电源产品的质量安全管控。由美国安全检定实验室公司（Underwriteries Laboratories Inc）推出的UL2743标准最早应用于便携式储能产品，由国际电工委员会（International Electrotechnical Commission）推出的IEC60335、IEC60730标准随后也应用于此类产品的管控。安规管控是产品销售到市场的最低要求，有利于指导研发人员在设计方案和测试的动态调整中不断优化，设计出安全可靠的产品。

Functional Safety (FS) taken from the TuV website:
o Functional Safety (FS)is the safeguard against hazards resultingfrom faulty and interrupted functionality. More and moresafety-related control systems are being used primarily in themanufacturing and process industries as well as in the railway,automotive and medical industries with the aim of reducing therisk of hazards.
Safety must be ensured under normal and/or undisturbed(oconditions and maintained in case of abnormal conditions, re-quiring products to be designed in such a way that fault, fail-ures and external influences do not result in cases of undetected loss of safety

The basic Functional Safety standard is lEc61508 and it is applica.ble to all industries. Each industry has its own nuance, therefore somany have developed their own standards based off lEC61508IEC60335 or lEC60730 will be applicable for Portable Power.
A number of standards will divide Functional Safety into 3 separateClasses(taken from lEC 60730-1:2022)
Class A: Control functions which are not intended to be reliedupon for the safety of the application.(e.g., speed control)Class B: Control functions which are intended to prevent an un-safe state of the appliance.(e.g., Cell voltage overcharge)Class C: Control functions which are intended to prevent specialhazardssuch as explosion or whose failure could directly cause ahazard in the appliance.(e.g.,explosion of the controlled equipment)

TheIEC60730safety standard defines the test and diagnostic methods that ensure the safe operation of embedded control hardware and software for household appliances. To achieve functional safety, it's necessary to remove all risk of hazards caused by system malfunction.

For Portable Power, somesituationssuch as overcharge or overtempertaure should be controlled by Class B.That's why we need tohave secondaryprotectorfromhardware side andClass Bsafety libararyfrom softwareside.
