With the widespread application of intelligent electronic products, fast charging solutions are receiving more and more attention, and the number of iterations is also becoming more frequent. In some electronic products with high usage frequency and high power consumption, the fast charging solution has also become the pursuit of most people, which can greatly shorten the charging time.
Everyone knows: P (power)=U (voltage) X I (current), Q (heat)=I2 (current) X R (resistance) X T (time). From this, it can be seen that the elements of fast charging cannot be separated from voltage and current. With the same resistance, the greater the current, the greater the heat dissipated over time. Below, we will explain the three main elements of fast charging schemes!
Raise voltage
The speed of mobile phone charging is actually controlled by the charging IC in the fast charging scheme, which achieves the goal of fast charging through secondary voltage reduction. Charging ICs mostly convert voltage, and a small portion is converted into heat, so high temperatures can lead to reduced power and long charging times, which is why charging mobile phones in summer is easy to get hot.
Increase current
As mentioned above, the charging IC will partially convert into heat during the secondary voltage reduction process. However, our other fast charging solution is to use low-voltage high current, which is what we call a dedicated charger. Although it reduces losses, customized chargers also bring compatibility issues.
Simultaneous adjustment
Huawei‘s SuperCharge uses a charge pump IC, which not only improves efficiency but also generates an output voltage greater than the input voltage. The fast charging solution provided by Yingruien is fast and stable.
After the above understanding, we have also gained a certain understanding of fast charging solutions. So how should we choose a suitable fast charging solution? Chip selection is also important, and here are 5 suggestions for everyone:
1. According to usage, it is divided into travel type, seat type, multi port seat type, and car charger.
2. The selection of internal chips is also important, and the types of fast charging are divided into Quick Charge technology, Pump Express fast charging technology, and USB PD fast charging technology.
3. When purchasing a mobile phone charger, try to choose products with "CCC" or other certification marks, and then choose a charger that matches your phone.
4. If you want to purchase all the compatible fast charging technologies from legitimate channels and non trustworthy merchants, they may seem the same, but in reality, they are very different.
5. Regular maintenance should be carried out on mobile phone chargers.
