Battery Charger

On June 13, 2016, the US Department of Energy (DOE) published a Final Rule pertaining to energy conservation standards in battery chargers – 10 CFR 430.32(z): Energy Conservation Program: Energy Conservation Standards for Battery Chargers. The new rule came into force on August 12, 2016 and will be enforced from June 13, 2018. 

The final rule covers:

  • Battery chargers for consumer products, including battery chargers embedded in other consumer products
  • Wireless battery chargers designed to operate in wet conditions
  • USB-charged devices and other DC-powered device USBs

Products within its scope include: cell phones, digital cameras, consumer IT products, audio/video products, toys, power tools, rechargeable toothbrushes, and water jets.

Registration:

efore offering the battery charger onto the market, it should be registered in the Compliance Certification Management System (CCMS). Registration has a validity period of one and following this the manufacturer or importer must re-register to continue selling the battery charger.

General Requirements:

Battery chargers manufactured on or after June 13, 2018, must have a unit energy consumption (UEC) less than or equal to the prescribed ‘‘Maximum UEC’’ specified in 10 CFR 430.32(z).

Product class description  Rated battery energy (Ebat**)  Special characteristics or battery voltage  Maximum UEC (kWh/yr) (as a function of Ebatt**) 
Low-Energy ≤5 Wh  Inductive connection in wet environments (eg. electric toothbrushes)  3.04 
Low-Energy, Low Voltage 

≤100 Wh  

 

<4 V  0.1440 * Ebatt + 2.95
Low-Energy, Medium Voltage  4-10 V 

Ebatt <10Wh, UEC = 1.42 kWh/y

Ebatt ≥10 Wh, UEC = 0.0255 * Ebatt + 1.16 

Low-Energy, High Voltage
>10 V  0.11 * Ebatt + 3.18
Medium-Energy, Low Voltage  100-3000 Wh  <20 V  0.0257 * Ebatt +0.815 
Medium-Energy, High Voltage  ≥20 V  0.0778 * Ebatt + 2.4 
High Energy  >3000 Wh    0.0502 * Ebatt + 4.53 
                                                                                                                   

**Ebatt = Rated battery energy as determined in 10 CFR part 429.39(a)
