The similarities and differences between the main control boards of 14KW dual gun charging stations for single-phase and three-phase electricity

The main control board of the 14KW dual gun charging station for single-phase and three-phase electricity has the following similarities and differences:

Similarities

• Basic functions are consistent: both can control and manage two charging guns, ensuring the safety and stability of the charging process, can charge two electric vehicles simultaneously, and must comply with relevant charging standards and communication protocols, and can effectively communicate and exchange data with the vehicle's battery management system.

• The main components are similar: they all include the main control chip, power module, communication module, metering module, relay drive circuit, charging interface circuit and other basic components. The modules cooperate with each other to achieve the control and charging function of the charging pile.

difference

• Power input: The main control board of the single-phase 14KW dual gun charging station has an input voltage of 220V and a high current; The input voltage of the three-phase power control board is 380V, and the current is relatively small.

• Electricity transmission efficiency: Three phase electricity has relatively less loss when transmitting high-power electricity, and the efficiency of electricity transmission is higher because of its high line voltage and low current.

• Charging speed: The 14KW dual gun charging station for three-phase electricity generally provides faster charging speed during actual charging, reducing vehicle charging time and improving efficiency, while the charging speed for single-phase electricity is relatively slower.

• The impact on the power grid: The extensive use of single-phase electric charging piles may lead to unbalanced power grid loads, affecting the stability and reliability of the power grid, and increasing power grid losses; The load characteristics of three-phase electricity are stable, which can effectively avoid the problem of unbalanced power grid load and reduce the impact and loss on the power grid.

• Equipment cost: The main control board of the single-phase 14KW dual gun charging station has a relatively low cost due to its simple circuit; The control board for three-phase electricity is expensive due to its complex circuit and high equipment requirements.

• Applicable scenarios: The single-phase 14KW dual gun charging pile is suitable for scenarios such as households and small unit parking lots where charging speed is not required; Three phase electricity is suitable for scenarios that require high charging speed, such as public parking lots and highway service areas.
