CSA C381.2-17:2019 pdf download.Energy performance of battery-charging systems and uninterruptible power supplies
1.1 General
CSA C381.2-17 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). Uninterruptible power supplies that utilize the standardized National Electrical Manufacturer Association (NEMA) plug, 1-15P or 5-15P, as specified in ANSI/NEMA WD 6-2016 and have an ac output are included in the scope.
1.2 Purpose
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 this Standard) for measuring a product's energy performance.
1.4 Terminology
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.
Back-up battery charger一a battery charger excluding uninterruptible power supplies (UPSs)
a) that is embedded in a separate end-use product that is designed to continuously operate using mains power (including end-use products that use external power supplies); and
b) whose sole purpose is to recharge a battery used to maintain continuity of power in order to provide normal or partial operation of a product in case of input power failure.
Batch charger一a battery charger that charges two or more identical batteries simultaneously in a series, parallel, series-parallel, or parallel-series configuration. A batch charger does not have separate voltage or current regulation, nor does it have any separate indicators for each battery in the batch.
Note: When testing a batch charger, the term "battery" is understood to mean, collectively, all the batteries in the batch that are charged together. A charger can be both a batch charger and a multi-port charger or multi-voltage charger.
Battery or battery pack)一an assembly of one or more rechargeable cells and any integral protective circuitry intended to provide electrical energy to a consumer product, and may be in one of the following forms:
a) detachable battery (a battery that is contained in a separate enclosure from the consumer product and is intended to be removed or disconnected from the consumer product for recharging); or
b) integral battery (a battery that is contained within the consumer product and is not removed from the consumer product for charging purposes).
Note: The word "intended" in this context refers to whether a battery has been designed in such a way as to permit its removal or disconnection from its associated consumer product.CSA C381.2-17 pdf download.
