Qualcomm announces Quick Charge 5 with support for 100W fast charging
Qualcomm presents a new version of its charging standard. Quick Charge 5 is based on the USB PD-PPS protocol and can fast charge up to 100W. This is only possible if smartphones have a battery that consists of two parts; otherwise the limit is 45W.
According to the manufacturer, Qualcomm’s Quick Charge 5 makes it possible to half charge a 4500mAh battery in five minutes. Full charging takes about 15 minutes. This is based on a telephone with a battery consisting of two parts. The halves can then be charged simultaneously, doubling the voltage. The feasibility of that maximum speed also depends on the cable used, AnandTech notes.
The new standard is the successor to Quick Charge 4 from 2016; the maximum charging power is 27W. With Quick Charge 5, Qualcomm embraces the usb power delivery programmable power supply protocol. The manufacturer no longer uses its own proprietary protocol for communication between the charger and smartphone. That means that devices with Quick Charge 5 support are also fully compatible with USB PD PPS chargers.
Quick Charge 5 chargers must be able to supply voltage from 3.3V to 20V and charge with 3A, 5A or more than 5 amps. Chargers must also be backwards compatible with previous QC versions and have overheat protection built in.
Along with the Quick Charge 5 standard, Qualcomm is announcing new components for charging batteries in smartphones. The new PMIC supports two-piece batteries and supports both wireless and wired charging.
