Outdoor power supply vehicle parameters

In 2020, 1.7 billion external power supplies (EPS) were in use in the EU27, of which 75% for residential use, on average 6.5 units per EU household. They converted 48 TWh/a of electricity from the 220V mains to the input needed by the powered products.

In 2020, due to Ecodesign measures, EU27 users saved € 0.9 billion on external power supplies. This is projected to increase to € 1.3 billion in 2030, a 16% saving. In 2030, the annual household expenses for EPS are projected to decrease from € 33 (without measures) to € 28.

From April 2020, Regulation (EC) 278/2009 was replaced by Regulation (EU) 2019/1782. The rules apply to both the active efficiency and the no-load power consumption. Active efficiency is the average efficiency when a power supply is connected to a device, for example a laptop, when it is being used.

If you design your power supply to support sudden voltage drops, it is possible to save the expense of the boost, as well as the cost, space and power consumption associated with the additional components.

This is because the datasheet covers the integrated circuit performance and can miss how the device will work in a closed loop or how it will interact with other components in the system. This is even more important when choosing a front-end power supply for an automotive design.

No-load power consumption is the power consumed when this is plugged into a power outlet but not connected to a device. Voltage converters, uninterruptible power supplies, battery chargers, halogen lighting converters and external power supplies for medical devices are excluded from these requirements.
