Secondary Batteries...

EV batteries still have storage capacity, typically at 80 percent, after they’re removed from their vehicles and can be reclaimed for a “second life” as stationary power sources. This should reduce the need for additional power production and shrinking landfill waste.

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

1.1 These requirements cover portable primary (nonrechargeable) and secondary (rechargeable) batteries for use as power sources in products. These batteries consist of either a single electrochemical cell or two or more cells connected in series, parallel, or both, that convert chemical energy into electrical energy by chemical reaction.

This Standard specifies the test method for measuring and reporting the energy performance of large battery charger systems.

Description: Terms currently in use in the field of stationary batteries are defined in this standard. This standard does not include terms specific to battery manufacturing activities or to nonstationary battery applications such as motive, portable, marine, or other such applications.

1.1 The requirements in this document evaluate the fire characteristics of a battery energy storage system that undergoes thermal runaway. The data generated will be used to determine the fire and explosion protection required for an installation of a battery energy storage system.

This is the harmonized CSA Group and UL standard for General Requirements for Battery-Powered Appliances. It is the first edition of CSA C22.2 No. 0.23, and the second edition of UL 2595. This edition of UL 2595 supersedes the previous edition published on May 22, 2013.
