Which power is better for commercial charging station motherboards?

The selection of commercial charging station motherboards is mainly considered from the following aspects:

1. Factors to Consider in Power Selection

Vehicle type and user requirements:

• For commercial scenarios dominated by commercial vehicles such as electric buses and electric logistics vehicles, due to their large battery capacity, in order to shorten charging time and improve operational efficiency, high-power charging pile motherboards are usually required, such as 60kW-120kW or even higher power DC charging pile motherboards. For example, the battery capacity of electric buses may reach 100-200kWh or more, and high-power charging stations can replenish a large amount of electricity for them in about 1-2 hours to meet their operational needs.

• If the main service is for commercial places (such as shopping malls, hotel parking lots, etc.) that serve passenger cars (such as private cars and ride hailing services), a 7kW -22kW AC charging pile motherboard is a more suitable choice. The 7kW charging station motherboard can fully charge a regular passenger car in about 4-6 hours, meeting the charging needs of vehicles during their stay in commercial places such as shopping, accommodation, etc; The 22kW charging station motherboard has a faster charging speed and is more attractive to users who have higher requirements for charging time, such as ride hailing drivers.

Limitations on site and power conditions:

• Considering the power capacity and distribution facilities of the site, if the power supply of the site is limited, installing high-power charging piles may lead to power overload. For example, in some old commercial buildings with small power transformer capacity, choosing multiple low-power (such as 7kW) charging pile motherboards and allocating power loads reasonably may be a more feasible solution.

• Meanwhile, the space of the venue will also affect the power selection. High power charging stations (especially DC charging stations) are usually bulky and require sufficient space for installation and heat dissipation. If the site space is limited, it may be necessary to choose a charging pile motherboard with slightly lower power and smaller volume.

Balance of operating costs and revenue:

• The equipment and installation costs of high-power charging station motherboards are relatively high, including the price of the charging station itself, the cost of power capacity expansion (if needed), and the cost of supporting facilities such as cables and distribution cabinets. Moreover, the electricity cost during high-power charging may also be higher (some regions have different electricity pricing policies for high-power consumption). Therefore, it is necessary to comprehensively consider the charging fee standards and expected charging capacity to evaluate the return on investment. For example, in commercial areas with strong charging demand and high charging prices (such as airport parking lots), installing high-power charging pile motherboards may require a large initial investment, but can generate good returns by charging higher charging fees and improving equipment utilization; In areas with relatively low charging demand, choosing lower power charging pile motherboards can reduce costs and minimize operational risks.

2. Recommended better power in common scenarios

Highway service area:

• A better choice is a 60kW -120kW DC charging pile motherboard. Vehicles on highways usually hope to continue driving after fast charging, and the service area has a large space and relatively sufficient power supply. High power DC charging stations can replenish sufficient power to vehicles in a short period of time (such as 30-60 minutes) to meet the needs of long-distance travel.

• Large shopping malls and shopping center parking lots:

• Mainly using AC charging station motherboards ranging from 7kW to 22kW. These places usually have a vehicle stay time of about 2-4 hours, and a charging station of 7kW-22kW can provide sufficient power for the vehicle during its stay. Moreover, the cost of AC charging station motherboards is relatively low, and installation and maintenance are also convenient, making them suitable for use in places with high vehicle traffic but relatively flexible charging times for individual vehicles.

Hotel and office parking lots:

• A 7kW-11kW AC charging station motherboard is more suitable. Hotel guests and office building users' vehicles stay for a long time and usually park and charge at night. Charging stations with a capacity of 7kW-11kW can fully charge the vehicles at night to meet their travel needs the next day. At the same time, the charging pile motherboard in this power range has achieved a good balance between cost and charging efficiency, making it a relatively economical choice for operators.

Logistics park and bus station:

• For electric logistics vehicles and electric buses, a 30kW-120kW DC charging station motherboard is a better choice. The operating routes of these vehicles are relatively fixed, and the charging time can be centrally arranged. High power charging stations can quickly charge the vehicles during their rest period, ensuring that the vehicles can be put into the next round of operation in a timely manner. For example, electric buses can be fully charged within 3-4 hours using high-power charging stations after returning to the station at night, ensuring normal operation the next day.
