Dual-port multi-protocol: Huawei’s first 65W GaN fast charge evaluation



As we all know, Apple’s ecology is almost invincible, but Huawei’s layout in recent years has shown us that the ecology of Huawei products also has the power to catch up. The linkage of hardware and software between Huawei’s mobile phones, notebooks, TVs, headsets and other products has gradually become more vivid. Smart devices are also troublesome to charge every day. The best solution is high-power multi-port gallium nitride fast charging.

Relatively speaking, there are not many gallium nitride chargers that are compatible with all Huawei’s fast charging protocols. Everyone expects Huawei’s own gallium nitride fast charging to achieve the effect of one charger to solve all Huawei devices.

This wait lasted from April to September. But the saying goes well: Good food is not afraid of late, this charger is really good, we conducted all-round testing, dismantling, and thoroughly studied this bowl of belated “good food”. Let us take a look at the evaluation of Huawei’s gallium nitride charger.

8. Temperature rise

Thanks to the successful mass production and commercialization of gallium nitride power devices, the miniaturization of high-power chargers has been achieved, allowing consumers to enjoy this new era of technology. Many readers are very concerned about the heat generated by gallium nitride chargers, so we have added warm Rise test, but first of all, we must understand a few small knowledge about temperature rise test.

Charger heat is related to power density, efficiency value, internal design, ambient temperature, etc. Products with low power density are large and have enough space to separate the component layout, surface temperature will be lower, but the volume is often very large. For products with high power density, vertical plug-in component stacking is often used internally to make the charger as small as possible for users to carry. In theory, the temperature will be hotter than products with lower power density.

In addition, single-port chargers and multi-port chargers have different heat generation due to different circuit designs. Single-port chargers are AC to DC direct output mode, and multi-port chargers are AC to DC to DC, and the heat generation is relative after the secondary voltage drop. The single-port charger will be higher.

As a reference, in the one-hour full-load test, the full-load temperature of low-power density GaN chargers is generally between 60-70 degrees, while the high-power density single-port GaN charger is generally around 70 degrees. The temperature of multi-port GaN chargers generally exceeds 70 degrees.

Dual-port multi-protocol: Huawei's first 65W GaN fast charge evaluation 47

The temperature rise of Huawei’s 65W 1A1C GaN charger was tested. The test condition was to conduct the test at a constant output of 20V 3.25A 65W for one hour in an incubator with a temperature of about 25°C. Before charging, the maximum temperature of the charger is 35.0℃.

Dual-port multi-protocol: Huawei's first 65W GaN fast charge evaluation 48

One hour later, the current maximum temperature is 86.1℃, and the temperature has risen by 61.1℃. The high temperature is concentrated on the upper end of the charger, and the overall temperature is relatively uniform.

Dual-port multi-protocol: Huawei's first 65W GaN fast charge evaluation 49

Looking at the other side, the current maximum temperature is 90.3°C, and the temperature has risen by about 65.3°C. The high temperature is concentrated on the upper end of the charger, and the overall temperature is relatively uniform.

Summary of temperature rise test

The one-hour full-load temperature rise link is used to test the heating of the charger under extreme use. Users rarely encounter this long-term full-load situation in daily use. The power of digital devices such as mobile phones, tablets, and power banks is not large, and the temperature rise will be more moderate. However, when charging a notebook, the power will be reduced as the power is gradually saturated, and the heat will also be reduced.

The current national standard requires that the surface temperature of the charger is not higher than 95 degrees. The maximum test temperature of this multi-port 65W GaN charger from Huawei is lower than the national standard and meets the safety standard.

Nine, load test

Minutes; after 52 minutes, the power will decrease with the gradual decrease of the current until the end of charging. The whole process takes about 2 hours. The maximum power is 19.61V 2.81A 55.25W.

Next, let’s take a look at the USB-A (purple) charging the Huawei P40 Pro. 7 minutes ago, the voltage stabilized at 5V and the current oscillated up and down 2A. After 7 minutes, the voltage dropped to 4V and gradually climbed. About 2A; 1 hour and 50 minutes, the current drops to 1.3A; 1 hour and 55 minutes, the voltage rises to 5V, and the current rises to about 2A; then the power and current show a gradual decline until the end of charging, the whole process takes about 2 In 45 minutes, the maximum power is 5.18V 2.1A 10.92W.

11. Ripple test

The chargers (power adapters) of most digital products on the market are DC output chargers, which are obtained through AC rectification, filtering, and voltage stabilization. The periodic and random clutter signals in the output voltage, voltage The rapid and slight fluctuation of the value is like water ripples, so it is called ripple.

For chargers with different designs and different materials, the filtering degree is different, and the ripple size is also different. Therefore, the ripple test is added to the charging head network to facilitate users to know the ripple test parameters of the tested product.
