USB Type-C/PD brings new vitality to the charging field. Type-C with PD functionality makes charging ubiquitous. For example, you can use the same charger to charge computers, mobile phones, and mobile power supplies; You can also share power with mobile phones, tablets, and laptops. When sharing electricity, you can change the direction of power supply, etc. You can use car batteries, lithium batteries for electric vehicles, and lithium batteries for portable devices as a charging treasure to charge your mobile phone and provide emergency needs.
Because Type-C/PD can make all devices that support Type-C/PD compatible, it can also define its own private charging scheme, which will bring many innovative and customized things to the charging field.
To support Type-C/PD charging, both the charger end and the charged device end need to undergo Type-C/PD modifications. In terms of hardware, it is necessary to add a Type-C/PD management chip. In terms of protocol, to support the PD protocol, you can add a user-defined protocol.
For chargers, there is no need to modify the design of the front-end AC/DC, but it must be able to interact with Type-C/PD chips for information and status. In this way, the Type-C/PD chip manages the charging process. The most significant thing about a mobile charging bank is that you can use the PD protocol for fast charging without using private protocols such as QC2.0 or QC3.0. You can use ready-made Boost or Buck circuits, or you can use different Bucks or circuits based on customer needs. Because input voltage and input current can be arbitrarily selected (<20V,<5A)
Using the PD protocol, both your phone and your charging bank can implement a direct charging scheme. Due to the lack of voltage conversion, direct charging has high conversion efficiency, no heat generation, and high security. Due to voltage switching during high-voltage charging, there is always a risk of heating. The PD protocol can monitor the temperature of the phone or charging bank, thereby adjusting the charging strategy.
For a charging bank, many IC companies used to focus on the chip development of the QC2.0/BC1.2 external power supply (charge out) side, but now there are more opportunities to make products in the internal power supply (charge in) section. As long as you choose a chip with Type-C/PD, you can make a highly personalized charging bank. In short, Type-C/PD will bring a second life to the charging bank market.
