便攜式儲能產(chǎn)品近些年來發(fā)展迅猛，與儲能電源質(zhì)量相關(guān)的安全事故也頻頻發(fā)生，買家或電商平臺越來越重視對儲能電源產(chǎn)品的質(zhì)量安全管控。由美國安全檢定實驗室公司（Underwriteries Laboratories Inc）推出的UL2743標(biāo)準(zhǔn)最早應(yīng)用于便攜式儲能產(chǎn)品，由國際電工委員會（International Electrotechnical Commission）推出的IEC60335、IEC60730標(biāo)準(zhǔn)隨后也應(yīng)用于此類產(chǎn)品的管控。安規(guī)管控是產(chǎn)品銷售到市場的最低要求，有利于指導(dǎo)研發(fā)人員在設(shè)計方案和測試的動態(tài)調(diào)整中不斷優(yōu)化，設(shè)計出安全可靠的產(chǎn)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)

TheIEC60730 safety 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.
