Charging: Power Delivery

Charging: Power Delivery USB Power Delivery 2.0 introduced some changes to the way that power ratings between devices are handled, making the standard more flexible than before. The old set of Power Profiles were removed in PD 2.0 and replaced by Power Rules that allow for a wider range of current negotiations. The USB 3.1 specification adopted Power Profiles instead, but is only rated up to 15W rather than 100W.

PD 3.0 made some tweaks to enhance power delivery, but the Power Rules are the same as PD 2.0 products. Rules are split into four target power categories; 7.5W, >15W, >27W, and >45W; each of which offers a range of voltage and current configurations. Sources supplying more than 15 watts offer voltages of 5 and 9 volts, those supplying more than 27 watts offer 5, 9 and 15 volts, and those supplying more than 45 watts offer 5, 9, 15 and 20 volts. The maximum 100W power supply is achieved with 20V and up to 5A, although all of the other modes cap out at 3A, depending on the required power.

USB Power Delivery offers the following features:

• Increased power levels from existing USB standards up to 100W.
• The power direction is no longer fixed. This enables the product with the power (Host or Peripheral) to provide the power.
• Optimize power management across multiple peripherals by allowing each device to take only the power it requires, and to get more power when required for a given application.
• Intelligent and flexible system-level management of power via optional hub communication with the PC.
• It allows low power cases such as headsets to negotiate for only the power they require.

Flame Retardant (LSZH)

Flame Retardant (LSZH) The cable material is made of flame-retardant material and is therefore suitable for network installations in public and commercial buildings, schools, institutions, etc., as there are high requirements for cable installations to be flame-retardant or their reaction to fire according to the latest fire regulation, as described in the Construction Products Regulation EN 50575 "Power, signal, and communication cables. Cables for general application in construction works subject to reaction to fire requirements".

The cables must also meet the requirements for a new European fire classification, determined by tests of energy content, acid formation, heat release, smoke production, droplet formation, and fire spread. The existing fire classes will be replaced with seven new categories from A to F, as detailed in the standard.

Typically, an exemption can only be given for 10% of the cables that are not flame-retardant in commercial buildings. However, to facilitate the work, it is therefore easiest to "simply" choose cables with the right approvals, within both power, network, speaker, and data cables for all fixed installations, when building new or modernizing.

The EN 50575 standard as a book is not free, but can be purchased online from official stores.

Quick Charge 3.0

Quick Charge 3.0 If you’re new to the concept of quick charging, the result is in the name: your smartphone charges up faster than it would without Quick Charge technology.

Qualcomm boasts a fourfold increase in charging times over conventional chargers with Quick Charge 3.0, up from the 40 percent speed increase offered by its first-generation technology. However, one of the interesting things to note is that Qualcomm isn’t touting massive increases in charging times over version 2.0, instead, the company is focusing on improved efficiency this time around.

Voltage
• 3.6 V to 22 V, dynamic with 200 mV increments
Max current
• 2.6 A or 4.6 A
Max power
• 36 W (12 V x 3 A)

The major new feature with 3.0 is INOV (Intelligent Negotiation for Optimum Voltage), which allows for a fined tuned power output and a more optimized charging cycle. Firstly, different batteries require different charging voltages. Version 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option. Quick Charge 3.0’s INOV communicates with the device to request any voltage between 3.2V and 20V at 200mV increments, allowing for a wider selection of voltages.

Importantly, Qualcomm has retained backward compatibility with its 2.0 and 1.0 standards. As the power draw is handled on the smartphone side, you will safely receive the maximum amount of power for your device using any of the certified chargers. However, you won’t achieve full charging speeds if you try charging newer phones with older lower power chargers.

Although Qualcomm supports Quick Charge in all of its new SoCs, it is still up to smartphone and tablet manufacturers to implement the specific circuitry required to make full use of the fastest charging speeds available.
