Full Description

Preface

This is the second edition of CSA C381.2, Test method for determining the energy performance of batterycharging systems. It supersedes the edition published in 2008 under the title Test method for determining the energy efficiency of battery-charging systems.

This Standard specifies requirements, definitions, and test methods for determinig the energy performance of battery-charging systems. It is written in SI (metric) units.

CSA acknowledges the use of U.S. Department of Energy's Uniform Test Method for Measuring the Energy Consumption of Battery Chargers CSA acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada (NRCan), BC Hydro, Manitoba Hydro, and the Ontario Power Authority (OPA).

Scope

1.1
This Standard covers the test requirements used to measure battery charger energy consumption for battery chargers intended to be operated from 115 V ac, 60 Hz line voltage connected by plug to wall receptacles or existing dc sources (such as automotive power jacks or USB ports).

1.2
This Standard applies to battery-charging systems that are intended to charge secondary battery chemistries such as nickel cadmium, lead acid, lithium ion, and nickel-metal hydride.

1.3
This Standard does not apply to primary cell chemistries such as alkaline "dry" cells.

1.4
The test method specified in this Standard is intended to complement the methodology contained in CSA C381.1. This Standard and CSA C381.1 define two classifications of products for the purpose of energy-performance testing; products within the scope of CSA C381.1 are not intended to be tested by this Standard. Annex B specifies requirements for determining the appropriate test method (CSA C381.1 or CSA C381.2) for measuring a product's energy performance.

1.5
In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
