Summary of the charging head network
Through the dismantling and summary of as many as 40 outdoor power stations, it can be seen that the outdoor power stations that support high-power charging and discharging are all designed with multi-string battery packs and bidirectional inverter modules, and are equipped with cooling fans to dissipate heat for the battery pack and inverter modules and dissipate heat in time. In order to improve conversion efficiency and reduce heat dissipation requirements, GaN devices have also begun to be introduced into inverter modules to replace traditional silicon devices to improve energy efficiency.
PD fast charging is added to the outdoor power station, which further improves the user experience, and can also power the laptop normally outdoors. In addition, the small-capacity outdoor power station can also be charged through PD fast charging, without the need to use a special charger, which is more consumer-friendly. Most power stations also support external solar panel charging, which can be used as the main power supply equipment in an environment where there is no mains power at all.
