What innovations does the main control board of the charging pile have in terms of energy saving?

The innovations in energy saving of the charging pile's main control board can be summarized into three main aspects: "hardware upgrade + intelligent algorithm + green energy collaboration", as follows:

Low loss at the hardware level：

• SiC/Si-MOSFET hybrid power device: The new generation of main control board adopts SiC-MOSFET as the high-voltage, high-current switch, with on-resistance reduced by 60%, switching loss reduced by 40%, and overall efficiency increased from 93% to 97%.

• High-frequency soft-switching topology: LLC resonance or totem-pole PFC elevates the switching frequency to over 100 kHz, reducing the magnetic core volume by 30% and lowering standby power consumption to < 0.5 W.

• Modular power supply: Integrating AC/DC, DC/DC, and PFC into a single power module reduces inter-stage losses and wiring harness, increasing power density by 1.5 to 2 times.

Intelligent energy-saving algorithm：

• Adaptive power scheduling: Real-time adjustment of output based on vehicle SOC, temperature, and grid load, which can reduce total energy consumption during the same period by 8% to 12%.

• Off-peak power priority strategy: The main control board is equipped with a built-in clock chip and an electricity price database, which automatically initiates charging during off-peak periods, saving users over 20% on electricity bills.

• Standby sleep mechanism: After 30 seconds without vehicle access, it automatically enters deep sleep, with the MCU clock reduced to kHz level, and the standby power consumption of the entire device is less than 1 W.

Green energy collaboration：

• Photovoltaic direct-drive channel: The main control board is equipped with a reserved MPPT interface, allowing direct connection to a 600 V photovoltaic array. During the day, it adopts a "photovoltaic priority, grid power supplement" strategy, reducing grid power consumption by 30%.

• Peak shaving and valley filling through energy storage: Linking with small lithium-ion battery or supercapacitor modules, energy storage supplies power during peak grid hours, arbitraging between peak and valley periods while reducing the need for transformer expansion.

• V2G (Vehicle-to-Grid) reverse power transmission: The main control board supports bidirectional metering and grid synchronization. When the vehicle is idle, it can feed excess electric energy back to the grid, realizing the benefits of "mobile energy storage".

Through the aforementioned hardware, algorithm, and system-level innovations, the new generation of charging pile main control boards not only enhance charging efficiency but also reduce overall energy consumption and carbon emissions by 15% to 25%, bringing significant economic and environmental benefits to operators and users.
