Full test of charging
Because this charger of Bess supports 30W fast charging, the device targeted at the full test of this charging is the iPhone 13 Pro Max, and the following is the actual test process.
This is the data change of the whole process of charging the iPhone 13 Pro Max using the USB-C of the Bess 30W charger, and the voltage rises from 5V to 9V into the fast charging state at about 3 minutes, and then drops from 9V to 5V into trickle charging at about 59 minutes, and the charging ends at 1 hour and 44 minutes.
The whole charging process is drawn into a curve, while the Apple 30W PD charger for the iPhone 13 Pro Max charging curve to add, the overall two curves are not much different, Beth 30W charger can charge 47% of the iPhone 13 Pro Max for half an hour, 83% for 1 hour, and it takes 1 hour and 44 minutes to fully charge.
Standby power consumption test
If the charger is often plugged into the socket and not used, it will consume power, but it is very small. Many readers want to know whether the charger is wasted if it is always plugged into the socket, and the standby power consumption test session is to answer this question.
After the power meter test, the charger in 220V 50Hz no-load power consumption of 0.163W, converted to a year's loss of electrical energy is about 1.42KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.852 yuan.
The no-load power consumption at 110V 60Hz is 0.161W, which translates to a year's loss of electrical energy of about 1.41KW·h, and if the market price is 0.6 yuan/KW·h, the charger's annual electricity cost is about 0.846 yuan.
Conversion efficiency testing
A charger is essentially a conversion device that is lost during the process and dissipated in the form of heat. We usually look at the charger above the parameter output 100W or 65W is the maximum output power that the charger can provide for the device, but the charger draws power from the socket is often larger, the following is the charger in the case of 220V 50Hz and 110V 60Hz AC input respectively carried out conversion efficiency test, the test results are as follows:
At 220V 50Hz, the output power of the charger in each voltage gear is fully tested: five gears are measured to measure the input power of the AC terminal of the power strip and the output power of the USB terminal, and the conversion efficiency of the available charger varies from 83.82% to 90.03% through calculation.
At 110V 60Hz, the conversion efficiency of the charger varies from 83.12% to 89.11%.
Ripple test
Due to the switching power supply in the charger, the secondary output of the transformer is not direct current, and it needs to be rectified and capacitor filtered, that is, there will be ripple in the charger output. The charging head network uses an oscilloscope to test the ripple value of the charger output, compare with the national standard, and detect the output quality of the charger. The lower the ripple, the higher the output quality of the charger.
This is the use of the charger at 220V 50Hz AC input ripple test, ripple test is divided into no load (Y axis current in the histogram is 0A) and heavy load (Y axis current in the histogram is non-0A) two kinds, the maximum is 36mVp-p, the charger is at 15V2A output; the minimum is 14mVp-p, the charger is in the 5V0A no-load state.
At 110V 60Hz, the maximum is 38mVp-p, the charger is in the 15V2A output state, the minimum is 14mVp-p, the charger is in the 9V0A no-load state.
Ripple test summary
In the national standard, the charger ripple requirement is not higher than 200mVp-p, and the Beth 30W charger has a good performance at 110V 60Hz, 220V 50Hz input voltage, and all output power ripple peak-to-peak are lower than 200mVp-p.
Temperature testing
As mentioned earlier, the charger will involve the problem of efficiency conversion, and the vast majority of the lost power is dissipated by heat, so the heat of the charger working for a long time is also an important part of the test. Let the charger output at 30W power for one hour, collect the surface temperature of the charger, and place the charger in a 25 °C incubator throughout the experiment.
First, let's take a look at the temperature performance of the charger in the mains environment of 220V50Hz.
After one hour the maximum temperature on both sides of the charger was 66.9°C.
The other two surfaces have a maximum temperature of 61.8°C.
Let's take a look at the 110V 60Hz mains environment.
After one hour the maximum temperature on both sides of the charger is 67.7°C.
The other two faces have a maximum temperature of 63.3°C.
1 hour full load stability test
After long-term use, will the charger be reduced due to overheating? The charging head network also tested the Beth 30W 1C1A charger.
The charger gear is adjusted to 20V1.5A, and the output is continuously output at 30W power for one hour, and the voltage and current are horizontal and straight during the test, without obvious fluctuations, and the use of full load for a long time is also quite stable.
