What type of EV Charging Station regulates voltage and current using the EV On-board charging system?

The correct choice is the AC Charging Station, as it utilizes the electric vehicle's on-board charging system to manage the voltage and current. In an AC charging setup, the electricity is delivered in alternating current, and the vehicle itself incorporates an onboard charger that converts AC power from the grid into the appropriate direct current (DC) to charge the battery.

This system allows for fine-tuning of the charging process, making it essential for regulating how much power is drawn from the charging station. As a result, the onboard charging system plays a critical role in ensuring the safety of the charging process, preventing overcharging, and optimizing charging efficiency.

In contrast, DC Charging Stations bypass the vehicle's onboard charger and supply direct current straight to the battery, which means they do not regulate voltage and current through the vehicle's systems. Both Level 1 and Level 2 Charging Stations are types of AC chargers, so they also rely on the onboard charger to handle the voltage and current regulation; however, there is a distinction in their power levels and charging speeds. The emphasis on the type of charging station that specifically indicates using the onboard system aligns best with the AC Charging Station.
