CEC California Energy Efficiency Certification

With the popularization of household appliances, the rapid growth of household appliances has brought huge energy consumption and aggravated environmental pollution.

Countries around the world have improved the energy efficiency of energy-using products and promoted energy-saving technology progress by formulating and implementing energy efficiency standards and promoting energy efficiency labeling systems,

thus reducing harmful emissions and protecting the environment. The United States has been China's second largest trading partner for several consecutive years, and the trade volume between China and the United States has been increasing year by year.

Therefore, exports to the United States cannot be underestimated. The strictness of the United States' product technical standards and import regulations is the best in the world. Understanding the US market access rules will

help Chinese products further open up the US market.

As the largest state in the United States, California has stricter requirements for energy efficiency. The California Electric Appliance Energy Efficiency Regulations, which the California CEC Energy Commission has been promoting since 1976,

are the only mandatory energy-saving regulations in the United States that can affect non-governmental consumer behavior and have played an important role in reducing energy consumption. The regulation stipulates that electrical products must first meet the equipment energy efficiency regulations when they are sold in California, USA. The regulations stipulate energy efficiency index requirements, measurement methods and phased implementation plans for 58 categories of electrical products. According to the requirements of the regulations, electrical products must be tested by qualified laboratories in accordance with relevant US regulations or standards, and can only be sold in California, USA after they are proven to meet the requirements.

California Energy Efficiency Summary

Test adjustment, unless otherwise specified, is tested according to the following test conditions.

CEC California Energy Efficiency Test Instrument

Power measurements must be tested with a calibrated volt-ampere meter or power analyzer. The instrument must be calibrated according to the IEC 62301 standard.

When the test power is 0.5W, the error must be less than or equal to 2%. When the test power is less than 0.5W, the error must be less than 0.01W.

The accuracy of the power test instrument must reach 0.01W or better. The error of the test voltage and current must be less than or equal to 2%.

CEC California Energy Efficiency Test Room

According to the IEC 62301 standard, the air flow in the test room must be 0.5m/s or less, and the surrounding ambient temperature must be controlled within the range of 23℃±5℃. The sample must be placed on a laboratory bench without heat conduction for testing. For products used outdoors, if there are additional test requirements, they must be stated in the report.

CEC California Energy Efficiency Test Voltage

According to the IEC 62301 standard, the fluctuation range of the test voltage cannot exceed ±1% of the specified test voltage and ±1% of the specified test frequency. If the input voltage on the nameplate is wide voltage, the test voltage is 115V/60Hz and 230V/50Hz. If the nameplate indicates single voltage input, the test voltage is one of the two test voltages that are close to each other. CEC California Energy Efficiency Judgment Results

California Energy Efficiency Law stipulates that from July 1, 2006, all external power supplies exported to California, USA must meet the average energy efficiency regulations and no-load power requirements in the following table (see Table 1)

Table 1 Average Energy Efficiency Regulations and No-load Power Requirements (Old)

Nominal Output Power Minimum Average Energy Efficiency in Working Mode

＜1 Watt 0.49 * Nominal Output Power

＞1 and ≤49 Watts 0.09 * Ln(Nominal Output Power) + 0.49

＞49 Watts 0.84

Maximum Power Consumption in No-load Mode

0 to ＜10 Watts 0.5 Watts

≥10 to ≤250 Watts 0.75 Watts

Note: Ln (Nominal Output Power) = The natural logarithm of the nominal output power (in Watts).

From January 1, 2008, all external power supplies exported to California, USA must meet the new

Average energy efficiency regulations and no-load power requirements in the following table TABLE2 (see Table 2)

Table 2 Average energy efficiency regulations and no-load power requirements (new)

Nominal output power Minimum average energy efficiency in working mode

＜1 Watt 0.5 * nominal output power

＞1 and ≤51 Watts 0.09 * Ln(nominal output power) + 0.5

＞51 Watts 0.85

Maximum power consumption in no-load mode

Any output 0.5 Watts 0.5 Watts

Note: Ln (nominal output power) = The natural logarithm of the nominal output power (in Watts).

All tests must take into account the load conditions of 100%, 75%, 50%, and 25% of the output current indicated on the nameplate (

Note: the error range of the load here cannot exceed ±2%), and record the input power, input current, power factor,

output voltage, and THD (total harmonic distortion) respectively, and then calculate the current energy efficiency value according to energy efficiency = (output voltage × output current) / input power,

then average the energy efficiency values ​​measured under the four load conditions of 100%, 75%, 50%, and 25% to obtain the average energy efficiency value. In addition,

the input power value when the output current is 0% load must also be tested. The average energy efficiency value and no-load power value obtained from the above tests are determined according to the

limit requirements of TABLE1 and TABLE2 to determine whether they meet which energy efficiency mark.

Significance of CEC California Energy Efficiency Certification

CEC energy efficiency standards and energy efficiency labels have been proven to be the most cost-effective way to reduce energy consumption, while bringing huge environmental benefits, and also providing positive returns for consumers. Research results show that the formulation and effective implementation of new energy efficiency standards and energy labels can improve the energy efficiency of products

play a significant role in improving environmental quality and improving people's quality of life.

Does CEC California Energy Efficiency Certification require factory inspection?

CEC certification does not require factory inspection, he only needs to ensure that the product meets the relevant energy efficiency requirements!

CEC California Energy Efficiency Certification Cycle and Validity

The product time for conventional power supply is 1 week, and the battery charging system needs to be registered for 3 weeks. The validity period of the CEC certificate is determined by the product!

Power CEC Energy Efficiency Certification Notes

For AC Input external power supplies, the California Energy Act stipulates that

If such devices are to be sold in California, they must obtain CEC (California Energy Commission’s) energy efficiency test certification before July 1, 2007.

If the device fails to meet the requirements of the new Appliance Efficiency Regulation, it is prohibited to be sold in California.

This energy bill has special requirements for the performance of switching power supplies. It has two levels, "Ⅲ" and "Ⅳ", namely the third and fourth levels.

It has relatively high requirements for the no-load power consumption and overall efficiency of switching power supplies:

The power supply device is implemented in two stages:

Battery Charging System CEC Certification Product Labeling Requirements

CEC requires that battery charging systems that meet the specifications must be marked with the corresponding symbol, specifically a circular mark with the two letters "BC",

as shown in the following figure. There are no requirements for the size and color of the symbol.

The mark must be easy to read and not easily damaged. It can be placed on:

A: product nameplate;

B: or on retail packaging and the first page of the manual;

However, it should be noted that if the product does not have retail packaging, it must be marked on the product nameplate in method A.
