CSA C812-16:2020 pdf download.Energy performance of large battery charger systems
1 Scope
1.1 CSA C812-16 specifies the test method for measuring and reporting the energy performance of large battery charger systems.
Note: This Standard is technology neutral.
1.2 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.
1.3 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.
Battery charger system (BCS) - a battery charger coupled with its batteries or battery chargers coupled with their batteries, which together are referred to as a "battery charger system".
Notes:
1) This term covers all rechargeable batteries or devices incorporating a rechargeable battery and the chargers used with them.
2) Battery charger systems include, but are not limited to,
a) electronic devices with a battery that are normally charged from AC line voltage or DC input voltage through an internal or external power supply and a dedicated battery charger;
b) the battery and battery charger components of devices that are designed to run on battery power during part or all of their operations;
c) dedicated battery systems primarily designed for electrical or emergency backup; and
d) devices whose primary function is to charge batteries, along with the batteries they are designed to charge. These units include chargers for power tool batteries and chargers for automotive, AA, AAA, C,D, or 9 V rechargeable batteries, as well as chargers for batteries used in larger industrial motive equipment and a la carte chargers.
3) The charging circuitry of battery charger systems might or might not be located within the housing of the end-use device itself. In many cases, the battery can be charged with a dedicated external charger and power supply combination that is separate from the device that runs on power from the battery.CSA C812-16 pdf download.
