With the accelerated popularity of the 5G market, the battery life of 5G, a major power-consuming consumer, has shrunk a lot compared to the 4G era, which has dragged down the experience of using 5G mobile phones. Therefore, various manufacturers have chosen to adopt higher fast charging. To make up for the lack of battery life, even a fast charge of 100 watts was made, which can replenish the battery in about 20 minutes.
At present, the mainstream fast charging above 60W on the market basically uses a charge pump + dual battery solution, but the Honor 50 series just released recently has handed over its own answer sheet, using a unique multi-pole ear + single battery The core solution realizes a safer 100W fast charging solution.
First, let’s review the charging specifications of the Honor 50 series:
Honor 50 Pro supports 100W fast charge and 20V5A input, which can charge 90% in 20 minutes and fully charge in 25 minutes;
Honor 50 supports 66W fast charge and 11V6A input, which can charge 70% in 20 minutes and fully charge in 45 minutes.
In principle, it can be simply understood that Honor has turned a single lane into a two-lane road in a battery. The ordinary single cell uses one positive and one negative two poles. Honor released the bipolar single cell technology. When it comes to putting down two positive and one negative and three tabs on a battery cell, it is equivalent to realizing “dual charging” in a battery core, thereby achieving a 66W fast charging effect on the Honor 50.
The Honor 50 Pro is further upgraded to “multiple ear” technology, compared to the triple ear solution, the charging efficiency has been upgraded again, so as to achieve the effect of 100W fast charging.
Compared with the current multi-cell technology used in mainstream mobile phones, the single-cell technology has more obvious advantages: it is safer, the battery is thinner, and the battery capacity is larger. At the same time, it can also avoid the loss of battery cell splitting.
The general dual-cell solution is to connect two battery cells in series through the package together, and cooperate with a special “dual charger”, which is equivalent to using a charger at the same time to charge the two batteries separately. The charging effect is doubled. In fact, the charging power of a single channel is not very high.
However, there are some obvious shortcomings in the solution of dual-cell series connection, that is, a higher impedance effect will be formed after the series connection of the dual-cell cores, which will bring higher heat during charging, which will not only increase the heat of the mobile phone. More serious, there will be a risk of damage to the internal circuit, and will accelerate the loss of the lithium battery, affecting the battery life.
The Honor 50 series adopts a more technically more complicated multi-pole single cell solution, which achieves the effect of multiple charging and discharging circuits in only one cell, and will not bring higher impedance. While doubling the charging power, it can also reduce heat generation and battery core loss.
Therefore, the fast charging of the Honor 50 series has obtained higher safety and lower charging temperature, and can also obtain a longer service life.
In the actual test of the charging effect of the author’s Honor 50 Pro, it only took 27 minutes to charge the battery of the whole machine from 0% to 100%, and it was maintained at a state of 36°-37° for almost the whole process, which was the same as the temperature of the human body. There has never been a hot condition, which is a temperature performance that was completely unattainable by a 100W fast charge before.
In addition, in this age of justice, thickness and weight are both important judgment options for a mobile phone. Generally, the traditional dual-cell solution requires two batteries to be packaged together, and not only needs to be wrapped in a thick “coat”. “It also needs to be equipped with two charging and discharging circuits. This will not only bring more weight, but also need to further squeeze an inch of space inside the mobile phone. Therefore, the current dual-cell fast charging solution models on the market are in thickness and The weight performance is not satisfactory.
The Honor 50 series has a natural advantage in the use of space due to the single-cell solution. The multi-pole circuit realizes the effect of “dual fast charging” internally, eliminating the need for multiple cells in a physical way. Stacking, so you can save more internal space.
Reflected in the mobile phone, the single-cell solution can achieve a thinner and thinner body. On the basis of 100W fast charging, the Honor 50 Pro also has an 8.05mm ultra-thin body and weighs only 187g. Previously, an experience that the flagship of fast charging of 100W could not reach.
At the same time, smaller batteries can also make room for more components in the inner space of inches of gold, and can more conveniently configure linear motors, large-size image sensors, etc., on a relatively thinner body. , To achieve a better comprehensive experience.
It is worth mentioning that in addition to adopting a highly secure charging solution inside the phone, Honor 50 also implements triple identity authentication on the charger side: cable, charging connector, and battery. When the mobile phone is plugged in for charging, it will immediately verify the authenticity of the above three. If it is a third-party unqualified accessory, the charging power will be reduced to ensure the safety of charging.
At the same time, Honor has not limited its vision to high-end flagship products. The 66W fast charge was previously only eligible for 5,000 yuan or more. However, Honor has used the Honor 50/50 SE two products to reduce 66W. High-power and safer fast charging solutions are popularized to 2000 yuan.
In the six months since Honor became independent, the 66W fast charging solution has been used to cover the entire new Honor product line through the Honor V40 series and the Honor 50 series. All systems are equipped with 66W fast charging as standard, allowing more user groups to enjoy the single The battery core dual circuit brings a faster, thinner and safer fast charging experience.
With the continuous exploration of single-cell technology, Honor is likely to popularize 66W single-cell fast charging to cheaper models in the future, allowing more people to experience safer and more stable fast charging effects.
In summary, it can be seen that the most important thing for Honor in creating fast charging technology is not simply the pursuit of speed, but a comprehensive and comprehensive user experience, and hopes that more users can experience the charm of super fast charging.
Zhao Ming also talked about Honor’s choice of fast charging in the interview after the press conference. He emphasized that the single-cell dual-circuit fast charging solution adopted by Honor 100W charging is based on multiple dimensions such as speed, safety, reliability, and phone thickness. Based on the comprehensive considerations, a balanced choice has been achieved, and Honor has always occupied a leading position in the single-cell multi-circuit charging solution.
Zhao Ming said that product development will never be absolutely advancing in one direction, regardless of others. This kind of unbalanced design is very undesirable.
