Principle of Car Charging Pile

Car charging piles work based on the principle of converting alternating current (AC) from the power grid to direct current (DC) or supplying AC power directly to the vehicle's battery management system. In AC charging, the charging pile steps down the voltage from the grid to a suitable level and provides it to the vehicle. The vehicle's onboard charger then converts the AC power to DC to charge the battery. In DC fast charging, the charging pile itself performs the AC to DC conversion and delivers high-power DC directly to the battery, bypassing the vehicle's onboard charger. This allows for much faster charging times but requires more advanced and expensive charging equipment. The charging process is controlled by communication protocols between the charging pile and the vehicle to ensure safe and efficient charging, including monitoring the battery's state of charge, temperature, and voltage to prevent overcharging and overheating.
