NRCan能效限值要求
Energy performance standard for battery chargers 
Product class 
and description   
 Rated battery energy 
 (Ebatt†)     
Special characteristic or batty voltage Maximum UEC (kWh/yr)(as a function of E batt†)
1-Low-energy  ≤5 Wh  inductive connection* 3.04
2-Low-energy,low-voltage <100 Wh <4 V 0.144*E batt + 2.95
3-Low-energy,medium-voltage  <100 Wh 4-10V For E batt<10Wh,1.42kWh/yr      E batt≥10Wh,0.0255* E batt+1.16 
4-Low-energy,high-voltage <100 Wh    >10V  0.11*E batt+3.18
5-Medium-voltage ,low-voltage 100-3000Wh  <20 V 0.257*E batt+0.815
6-Medium-voltage ,high-voltage 100-3000Wh  ≥20 V 0.0778*E batt+2.4
7-High-energy  >3000Wh     0.0502*  E batt+4.53
   
E batt=rated battery energy
UEC=unit energy consumption
kWh/yr=kiowatt-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 toothbroushes).
