What is Power Delivery (PD)?
Power Delivery (PD) is a power management technology that is designed to significantly enhance the charging capabilities of electronic devices through USB-C ports. Introduced as part of the USB-C specification, Power Delivery allows the power sent to a device to be dynamically adjusted, speeding up the charging process and allowing more demanding devices such as laptops to be powered.
Development of Power Delivery technology
Power Delivery technology was introduced to address the limitations of traditional USB standards in terms of power transfer. Earlier versions of USB were limited to low voltage and current, making it impossible to charge larger devices such as laptops. Power Delivery changes this situation, allowing up to 100 W of power to be transmitted at voltages up to 20 V and currents up to 5 A.
Differences between Power Delivery and traditional USB charging
Traditional USB charging, often referred to as USB Battery Charging (BC), is limited to 5 V and typically 1.5 A, giving a maximum of 7.5 W of power. This is sufficient for charging smartphones and some tablets, but insufficient for charging more demanding devices. Power Delivery offers much greater flexibility and efficiency. Thanks to dynamic power management, PD can adapt the voltage and current to the needs of the device being charged, which not only speeds up the charging process, but also increases its efficiency and safety.
Power Delivery technology applications
Power Delivery is widely used in modern electronic devices. In smartphones and tablets, PD enables fast charging, which is particularly useful when users need a quick battery recharge. In laptops and ultrabooks, Power Delivery allows devices with high power requirements to be powered, eliminating the need for separate, large power supplies. In addition, PD technology is used in monitors, docking stations and other accessories that can be powered by a single USB-C connector, significantly simplifying desktop setup and reducing the number of cables.
Enhanced charging security
Power Delivery also enhances the charging security of devices. Thanks to advanced communication mechanisms between the charger and the device, PD can monitor and adjust charging parameters in real time. This means that the risk of overheating, overcharging or damaging the battery is significantly reduced. PD technology is designed to automatically adjust power, ensuring that each device is charged in the safest and most efficient way.
Saves space and simplifies the workstation
With Power Delivery technology, it is possible to reduce the number of cables and chargers needed to power various devices. One PD charger and USB-C cable can replace many different chargers, which not only saves space but also simplifies the management of the charging infrastructure. In offices, homes and when travelling, fewer cables and chargers mean less clutter and more convenience.
How does Power Delivery technology work?
One of the key elements of Power Delivery technology is the advanced communication mechanism between the power source (the charger) and the receiver (the device being charged). When a USB-C cable is connected to a device, initialisation and power negotiation takes place. The charger and the device exchange information about the maximum power they can deliver and accept, allowing dynamic adjustment of charging parameters.
PD – Power profiles
Power Delivery uses so-called power profiles, which define the different levels of power that can be delivered to a device. These profiles can range from low voltages and currents for small devices to high voltages and currents for larger devices. For example, a PD may start charging at a low voltage of 5 V and gradually increase to 9 V, 15 V or 20 V, depending on the needs of the device. Power profiles are dynamically negotiated and adjusted in real time to ensure optimal charging.
