Energy Storage Unit

(a) General requirements—(1) Batteries of the unsealed type shall be located in enclosures with outside vents or in well ventilated rooms and shall be arranged so as to prevent the escape of fumes, gases, or electrolyte spray into other areas.

(2) Ventilation shall be provided to ensure diffusion of the gases from the battery and to prevent the accumulation of an explosive mixture.

In June 2015, the ASME Council on Standards and Certification approved the creation of a new Standards Committee on Safety Standards for Thermal Energy Storage Systems (TES).

Intended Use
The objective of Standards issued as part of the Canadian Electrical Code, Part II, is to give consideration to the prevention of injury to persons and damage to property through proper design, good construction, and high quality of work. These safety Standards are intended to provide requirements for the design and construction of electrical equipment, primarily to address fire and electrical shock hazards and for use throughout Canada in conformity with the rules of the Canadian Electrical Code, Part I.

The sizing of nickel-cadmium batteries used in standby operation for stationary applications is discussed in this recommended practice

This guide describes methods for selecting the appropriate type of valve-regulated, immobilized-electrolyte, recombinant lead-acid battery for any of a variety of stationary float applications. The purpose of this document is to ensure that the reader is aware of all significant issues that should be considered when selecting VRLA batteries, so that the user might make an informed decision

A method for properly sizing the PV array and battery for stand-alone PV systems where PV is the only charging source is recommended (in conjunction with IEEE Std 1013TM). Load calculations and determination of solar radiation in the sizing of the system need special attention. Additionally, the critical nature of the load in deciding an acceptable annual availability needs to be considered

IEC 60086-2:2015 is applicable to primary batteries based on standardized electrochemical systems. It specifies the physical dimensions, the discharge test conditions and discharge performance requirements. This thirteenth edition cancels and replaces the twelfth edition (2011) and constitutes a technical revision.

IEC 60086-4:2014 specifies tests and requirements for primary lithium batteries to ensure their safe operation under intended use and reasonably foreseeable misuse. This fourth edition cancels and replaces the third edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
 - Harmonisation with the second edition of IEC 62281;
 - Alternative protective circuits in 7.1.1;
