Battery chargers

Energy Efficiency Regulations

Regulatory definition

Battery charger, a device that charges the battery of a wheelchair, golf cart, low-speed vehicle or any other end-use product. It does not include any of the following:

• a device that charges the battery of a vehicle other than a wheelchair, golf cart or low-speed vehicle
• a device that charges the battery of a medical device
• a wireless battery charger, other than a wireless battery charger that is inductive and designed for wet environments or
• a backup battery charger, a device that:
  • is incorporated into an end-use product, including a device that is incorporated into an uninterruptible power supply or that uses an external power supply, that is designed to operate continuously using mains power and
  • recharges a battery that is used to maintain the continuity of electrical power to the end-use product such that the product can continue its full or partial operation in the event of a failure of mains power

Compliance date

Energy efficiency standard

Energy performance standard for battery chargers

Product class and description	Rated battery energy (Ebatt†)	Special characteristic or battery voltage	Maximum UEC (kWh/yr) (as a function of Ebatt †)
1 - Low-energy	≤5 Wh	Inductive connection*	3.04
2 - Low-energy, low-voltage	<100 Wh	<4 V	0.1440 * Ebatt + 2.95
3 - Low-energy, medium-voltage	<100 Wh	4-10 V	For Ebatt <10 Wh, 1.42 kWh/yr Ebatt ≥10 Wh, 0.0255 * Ebatt + 1.16
4 - Low-energy, high-voltage	<100 Wh	>10 V	0.11 * Ebatt + 3.18
5 - Medium-energy, low-voltage	100-3000 Wh	<20 V	0.0257 * Ebatt + 0.815
6 - Medium-energy, high-voltage	100-3000 Wh	≥20 V	0.0778 * Ebatt + 2.4
7 - High-energy	>3000 Wh		0.0502 * Ebatt + 4.53

E_batt= rated battery energy
UEC = unit energy consumption
kWh/yr = kilowatt-hours per year
Wh = watt-hours
V = volts

† E_batt used in this Table is the sample mean of the measured battery discharge energy.
* Inductive connection and designed for use in a wet environment (e.g. electric toothbrushes).

Energy efficiency report requirements
