Xiaomi officially announced: 30W super wireless flash charging is a self-developed solution

Recently, Xiaomi officially announced the MI CHARGE TURBO super wireless flash charger, the world's first 30W super wireless flash charger, which can wirelessly charge a 4000mAh battery to 50% in 20 minutes and fully charge it to 100% in 69 minutes.

However, some netizens have questioned this technology. Is it a ready-made solution from a supplier partner or a self-developed technology from Xiaomi? In this regard, Xiaomi's product director Wang Teng posted on Weibo this afternoon that 30W Super Wireless Flash Charge is a leading solution developed by Xiaomi, which includes many innovative technologies:

1. Efficient direct charging architecture: Circuit architecture design, device selection, protection design, etc. are all self-developed by Xiaomi.

2. Charge turbo 2.0 technology: 4:1 direct charging algorithm, charging strategy, protection algorithm, etc. are all self-developed by Xiaomi.

3. Wireless charging private protocol: Xiaomi's wireless charging private protocol process, security encryption mechanism algorithm, etc. are all self-developed by Xiaomi.

4. Xiaomi wireless dual-band transmission protocol: Dual-band transmission supports in-band transmission and out-of-band transmission. The protocol flow between the transmitter chip and the communication chip, the protocol flow between the mobile phone AP and the communication chip, the out-of-band protocol flow between the mobile phone AP and the receiving chip, and the protocol flow between the mobile phone and the communication chip of the transmitter are all defined and developed by Xiaomi.

5. High-power reverse charging: BOOST+ reverse 1: 2 boost architecture and reverse charging protection strategy are both Xiaomi's self-developed designs.

Wang Teng said that our suppliers Volta and IDT designed a high-power wireless charging chip for Xiaomi according to Xiaomi's design requirements and circuit architecture, thereby achieving a wireless charging power of up to 30W and extremely high conversion efficiency.
