Active cooling is required only on the infrastructure side of ___ charging.

Active cooling is required only on the infrastructure side of ___ charging.

• A. Level 1
• B. Level 3
• C. Wireless
• D. Level 2

Answer: (D)

Active cooling in charging systems is all about removing heat produced by the power electronics. When you’re charging at Level 2, the charger (the infrastructure) handles a substantial amount of power—enough that the charging hardware itself can heat up quickly. To keep the equipment safe and reliable, it needs active cooling, such as fans or a liquid cooling loop, to move that heat away. The vehicle’s onboard charger is inside the car and is designed with its own thermal management, so the cooling needs aren’t the same kind of constraint for the vehicle side. That’s why the statement says the cooling requirement is on the infrastructure side and not the vehicle side for Level 2 charging. Level 1 uses much lower power, so cooling the charging hardware is typically not an issue, and Level 3 involves much higher power with significant cooling needs, but the point here is that Level 2 charging specifically requires active cooling on the charger itself to safely handle the heat generated by the infrastructure electronics.
