IEEE 1660-2008 pdf free.IEEE Guide for Application and Management of Stationary Batteries Used in Cycling Service.
This guide provides information on the differences between stationary standby and stationary cycling applications and appropriate battery management strategies in cycling operations. While the primary emphasis is on lead-acid batteries, information is also provided on altcrnativc and emerging storage technologies. The management of battery systems in stationary standby service is covered in other IEEE documents and is beyond the scope of this guide.
1.2 Purpose
This guide is meant 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 11w standby versus cycling applications.
2. Normative references
The following referenced documents are indispensable for the application of this document (i.e.. they must be understood and used. so each referenced document is cited in te, and its relationship to this document is explained). For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any aniendiiients or corrigenda) applies.
For the purposes of this guide, the following terms and definitions apply. The Authoritative Dictionary of IEEE Standards Terms [B2] should be referenced for terms not defined in this clause.
3.1 Definitions
3.1.1 cyeling: The repeated charge/discharge of a storage battery. Some batteries are rated by their ability to withstand repeated, deep discharge cycles.
3.1.2 standby power system (emergency and standby power): An independent reserve source of electric energy that, upon failure or outage of the normal source, provides clectric power of acceptable quality so that the user’s facility may continue in satisfactory operation.
3.1.3 stationary battery: A storage battery designed for service in a permanent location.
4.1 Standby versus cycling batteries
The term “stationary battery” is not synonymous with “standby battery application.” There arc two primary applications for stationary batteries:
a) Standby [c.g., uninterruptible power supply (UPS)). also known as backup or float applications
b) Cycling (primary-power source batteries. e.g., ofT-grid hybrid power sources and distributed energy resources ([)ER) applications)
Cycling scrvicc is divided between “shallow cycling” [typically 10% to 20% depth of discharge (DOD)) and “deep cycling” (typically 50% to 80% DOD).
flattery construction, operation, and maintenance are very different for each of these two applications. While some batteries are capable of both standby and cycling service. using a battery specifically designed for standby service in a cycling application may result in short life and poor performance, and vice versa. ilicrefore, the correct battery must be selected for each application and the correct maintenance standard(s) and recommendations ftllowed for the application.
Typical applications in the standby category include telecommunications backup, emergency lighting, and UPS. Typical stationary cycling applications include off-grid renewable-energy applications, such as PV, and grid-connected applications, such as DER. Sec Table 1.IEEE 1660 pdf download.
