This is the first edition of CSA C812, Energy performance of large battery charger systems.
This Standard specifies the test method for measuring and reporting the energy consumption of large battery charger systems.
This Standard has been harmonized with the requirements for testing and evaluating the energy consumption of large battery charger systems specified in the California Energy Commission Appliance Efficiency Regulations, CEC-400-2014-009, which refers to Energy Efficiency Battery Charger System Test Procedure, Version 2.2, dated November 12, 2008, published by ECOS and EPRI Solutions.
CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada, B.C. Hydro, Manitoba Hydro, Hydro Quebec, Ontario Ministry of Energy, Canadian Electricity Association, Independent Electricity System Operator, and Nova Scotia Energy.
This Standard specifies the test method for measuring and reporting the energy performance of large battery charger systems.
Note: This Standard is technology neutral.
This Standard applies to large battery charger systems such as forklifts, autoettes, electric personal assistive mobility devices, and low speed vehicles that are battery charger systems with a rated input power of more than 2 kW, except those
a) used to charge a motor vehicle that is powered by an electric motor drawing current from rechargeable storage batteries, fuel cells, or other portable sources of electrical current, and which may include a nonelectrical source of power designed to charge batteries and components thereof;
b) used to charge a battery or batteries in an illuminated exit sign;
c) with input that is three phase of line-to-line 300 volts root mean square (rms) or more and is designed for a stationary power application;
d) that are battery analyzers;
e) that are uninterruptible power systems as defined by IEC 62040-3; or f) that are for golf carts.
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; and 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 and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
