When fleet companies choose the power of a DC charging station, they need to consider many factors. Here are some common power selection suggestions:

1. 30kw/40kW DC Charger

Applicable scenarios: Suitable for fleet companies that have small electric vehicle fleets and do not have particularly high requirements for charging speed. For example, some small online car-hailing or taxi fleets that mainly travel short distances in the city and have more parking and charging time. If the fleet's operating model allows the vehicle to travel a short distance each time and have enough time to charge, then a 30kW DC pile can meet basic needs.

Advantages: The price is relatively low, the equipment cost investment is relatively low, and the load requirements on the power grid are relatively low. It can also be well adapted to some areas with limited power supply capacity. The damage to the vehicle battery is relatively small, which can extend the battery life to a certain extent.

2. 60kW DC Charger：

Applicable scenarios: Suitable for medium-sized fleets, such as some urban commuter bus fleets, medium-sized logistics and distribution fleets, etc. The vehicles in these fleets have relatively long mileages and need to replenish more power in a short period of time, but they do not have extremely high requirements for charging speed like large long-distance transport fleets.

Advantages: The charging speed is significantly higher than that of 30kW DC piles, and more power can be charged to the vehicle in a short period of time to meet the daily operation needs of the vehicle. At the same time, 60kW DC piles are more common in the market, the technology is relatively mature, the stability and reliability of the equipment are high, and the subsequent maintenance costs are relatively controllable.

3. DC charging station with power of 120kW and above:

Applicable scenarios: For large long-distance passenger transport fleets, large logistics transport fleets, and some high-end online car-hailing or taxi fleets that have extremely strict requirements on charging time, DC piles with power of 120kW or above are more suitable choices. The vehicles in these fleets have long mileage and tight operating hours, and they need to charge the vehicles with as much power as possible in the shortest time to ensure efficient operation of the vehicles.

Advantages: The charging speed is very fast, which can significantly shorten the charging time of the vehicle and improve the operational efficiency of the fleet. For example, some large logistics vehicles have large battery capacities, and high-power DC piles can complete charging in a shorter time, reduce the time the vehicle stays at the charging station, and increase the actual operating time of the vehicle, thereby improving economic benefits. However, high-power DC piles have high requirements for the power grid, and it is necessary to ensure that the charging station has sufficient power capacity to support its operation.

When choosing the power of a DC charging stations, fleet companies should comprehensively consider factors such as the size of the fleet, vehicle type, operating model, and power supply, and choose the DC charging station power that best suits them.
