Battery Management System

The standard is intended to be a basic functional safety standard applicable to all kinds of industry. It defines functional safety as: “part of the overall safety relating to the equipment under control (EUC) and the EUC control system which depends on the correct functioning of the E/E/PE safety-related systems, other technology safety-related systems and external risk reduction facilities.”

This guidance provides for the protection of stationary battery systems, which include the battery and DC components to and including the first protective device downstream of battery terminals. Recommendations are not intended to set requirements; rather, they present options to the battery system designer concerning the types of protection available.

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 guide is intended to provide assistance to users of stationary battery systems in determining appropriate battery management strategies that may be applied by addressing the primary similarities and differences in battery design and operation for standby versus cycling applications.

The document presents general requirements that Telcordia and participating industry representatives view as applicable to large format non-aqueous rechargeable lithium batteries to replace or interoperate with conventional batteries (i.e., Lead-Acid, nickel-based); function seamlessly with DC power plants; and provide reliable backup power to load equipment in a network environment of a typical telecommunications service provider.

Wiring methods. The provisions of this section do not apply to conductors that are an integral part of factory-assembled equipment.

The document discusses operational parameters that may be observed by battery monitoring equipment used in stationary applications and the relative value of such observations. Although a list of commercially available systems is not given, a means for establishing specifications for the desired parameters to be monitored is provided.

This is an informative document covering the broadest aspects of automatic monitor systems as they apply to traction battery applications. The subject of the guide covers those monitor characteristics and features which need to be controlled, though not necessarily currently available. In addition it accommodates those characteristics which are measurable and provides interpretations of accuracy and reliability of the information generated. This publication has the status of a Technical Report - type 3

1 Scope
1.1 These requirements apply to controls that employ solid-state devices and are intended for specified safety-related protective functions.

1 Scope
1.1 These requirements apply to non-networked embedded microprocessor software whose failure is capable of resulting in a risk of fire, electric shock, or injury to persons.
