1. Selection of power devices

High-power charging piles need to use power devices that can withstand high current and high voltage,

which determines whether the equipment operates safely and has a long service life.

For example, the 30-kilowatt power module unit based on three-phase LLC converter technology can meet the existing market requirements for high power density,

high power, and high efficiency. Power devices are used in PFC rectifier circuits and LLC DC/DC circuits of charging piles,

and play an important role in improving circuit efficiency and optimizing circuit structure.

2. Busbar copper bar area

The power of the charging pile determines the selection of its bus’s current carrying capacity level. For example, charging piles with higher power should choose copper bars with larger contact area and thickness to increase the current carrying capacity, while charging piles with low power can choose smaller copper bars to achieve higher cost performance.

3. Temperature rise test requirements

The power of the charging pile will affect the temperature rise test requirements of its components. Although the 1.25 coefficient may be deleted in the new version of the standard, it will not have a fundamental impact on the selection of contractors, because the charging pile’s requirements for component temperature rise tests are much higher than the requirements of the component’s standard.

4. Installation environment

The installation environment of the charging pile will also affect the choice of power. In commercial areas or on highways, high-power charging piles may be needed to meet the simultaneous charging needs of multiple users; while in residential areas, lower-power charging piles can be selected.

5. Hardware device composition

The power of the charging pile will also affect the composition of its hardware equipment. Charging modules account for up to about 50% of charging pile hardware equipment, of which power devices account for about 30%, and other components such as magnetic components, semiconductor ICs, capacitors, and PCBs also occupy a certain proportion.

6. Market demand

With the rapid development of new energy vehicles, the market’s power requirements for charging piles are also constantly increasing. High-power charging piles face a blue ocean market because of their ability to provide faster charging services, especially in the field of DC fast charging.

In summary, the power of the charging pile has an important impact on device selection, including the selection of power devices, bus voltage level, temperature rise test requirements, installation environment, hardware equipment composition, and market demand. When selecting components for charging piles, these factors need to be considered comprehensively to ensure the performance and safety of the charging pile and make it work at its best.
