IEC

This part of the IEC 62932 series specifies general information relating to the requirements and typical methods of test for flow battery system.

A flow battery is an electrolyte cyclical form battery, and a rechargeable battery mainly applicable to broad applications such as energy storage, independent power supply, grid stabilization, and a stabilization use of renewable energy. This standard is applicable to all flow battery systems.

This regulation will define terms applicable to the electrical energy storage systems

The scope of this NWIP is to prepare normative documents on safety dealing with: 1) main risks related to couples of use cases and associated technologies; 2) technical contents and results to be included in the safety report and auditing framework; 3) list of main features to be validated by testing; 4) scale at which the storage system must be tested; and 5) recommendations to prevent or mitigate accidental effect.

There are various sub standards (6-1, 6.-2, etc.) that apply to EMC. Information from IEC 61000-6-1 covers EMC immunity requirements for electrical and electronic apparatus intended for use in residential, commercial and light-industrial environments. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No tests need to be performed at frequencies where no requirements are specified. This generic EMC immunity standard is applicable if no relevant dedicated product or product-family EMC immunity standard exists.

"The standard applies to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72,5 kV. The object of the standard is to give a) Definitions for degrees of protection provided by enclosures of electrical equipment as regards: 1) protection of persons against access to hazardous parts inside the enclosure; 2) protection of the equipment inside the enclosure against ingress of solid foreign objects; 3) protection of the equipment inside the enclosure against harmful effects due to the ingress of water.

This Part of IEC 62485 specifies the basic requirements for secondary batteries and battery installations. The requirements regarding safety, reliability, life expectancy, mechanical strength, cycle stability, internal resistance, and battery temperature, are determined by various applications, and this, in turn, determines the selection of the battery design and technology. In general, the requirements and definitions are specified for Lead-Acid and Nickel Cadmium batteries. For other battery systems with aqueous electrolyte, the requirements may be applied accordingly.

This part of IEC 62485 applies to secondary batteries and battery installations used for electric vehicles (e.g., in electric industrial trucks, including lift trucks, tow trucks, cleaning machines, automatic guided vehicles), battery powered locomotives, electric vehicles (e.g., goods vehicles, golf carts, bicycles, wheelchairs) and does not cover the design of such vehicles. The standard covers Lead dioxide-Lead (Lead-Acid), nickel oxide-cadmium, nickel-oxide-metal hydride and other alkaline secondary batteries.
