“Thermal management has been a common challenge in earlier generations of wireless charging systems. The fan greatly reduces the amount of generated heat,” Moon said. The benefits of the fan are twofold: By reducing the temperature, it not only helps prevent the risk of overheating – which can cause a phone to stop charging while it cools down – it also enhances efficiency. “Simply put, a phone can charge faster when it’s cooler,” Moon said.

By adopting the Qi2 charger, Nissan drivers get faster, steadier charging – and fewer daily frustrations. That’s because the Qi2 charger delivers consistent power up to 15 watts, compared to the 5 watts of many previous-generation chargers.

“Previous designs would adjust power delivery, especially if the charger became too warm,” Zimmerman said. “In this latest version, the need for that fluctuation is greatly reduced. Users will arrive at their destination with a battery more charged than was possible with the outgoing charger.”

Combined with the cooling fan, the time it takes to go from 10% charged to 90% charged was reduced from four hours to just over 90 minutes (footnote 3).
